Less than 12 hours light flowering

We all accept as gospel that pot plants must have a 12/12 light schedule to promote flowering. Maybe I'm too linear in thinking, but, if flowering is prompted by shorter days why won't even longer nights promote flowering even more? If maturity is sped up by shorter day For example, I give my cannabis plants 12 hours of light each day for most of the flowering stage (as is considere the standard for flowering cannabis plants), then 3-4 weeks before harvest, I'd reduce that to 11 hours of light each day, then a few days later I'd change to 10 hours of light each day, etc Stay with the 12/12. Cannabis only needs 12 hours of darkness to put it into the Flowering stage. Therefore, although your friend is saving money on the power bill he is limiting the amount of growth that normal plants would receive. It is okay for 8/16, but not Optimum Cannabis plants need short days (or more specifically long nights) in order to start flowering and make buds. Most indoor growers give their plants 12 hours of darkness and 12 hours of light each day to initiate budding and continue with that 12/12 light schedule until it's time to harvest

Anyone Tried Flowering With Less Than 12 Hours Of Light

Most strains will start flower at about 14-14.5 hours light outdoors and indoor if gradual decrease in time. Yeah it looks like 14.5 hours is the critical day length, at least for most non-equatorial strains. And notice that there was rapid formation of new florets until it got down to 12.56 hours, so might as well say 13 hours Therefore, if the plant is not supplied with light for 12-14 hours in a day, then it means that its light cycle has been disrupted. If less light is supplied, then the plant won't transition as required. It will flower, but you won't get enough yield from the plant. First Buds Stag They put together alot of data which shows that during most of flowering the plant recieves up to 14 1/2 hrs of light and less than 10 hrs of darkness. it fluctuates throughtout the flowering season ending with a light cycle of pretty much 13/11. I belive it some what like 12 hrs 45 minutes and 11 hrs and 15 minutes

Does shorter light periods create more potent buds? Grow

  1. Plants that prefer less than 12 hours of daylight to flower are called short day plants. These are plants that typically flower in spring or fall. One example is the chrysanthemum (Chrysanthemum.
  2. FLOWERING: 12-12, THE INDOOR GROWER SOP 12-12, the even split of 12 hours of light and 12 hours of darkness, only occurs naturally close to the equator. Indoor growers rely on timers to artificially dial in this light-dark cycle. During the day or lights-on period, two receptors, phytochrome red and phytochrome far-red, are in balance
  3. g shrubs are larger and more compact than ground cover plants. Dwarf shrub varieties have upright growth rather than spreading across the ground. Most ground cover plant species grow less than 1 ft. (30 cm) tall. However, the flowering shrubs on this list grow to between 2 and 3 ft. (0.6 - 1 m) high

Only using 8 hours of light for flower? instead of 12/12

  1. For cannabis to flower, there must be at least 12 hours of continuous darkness. This allows for the use of a series of shorter light schedules while the plant is in veg —as long as the plant receives less than 12 hours of continuous darkness, it will stay in veg
  2. Anything equal to or less than 12 hours of light will trigger flowering in.
  3. Short-day plants form flowers only when day length is less than about 12 hours. Many spring and fall flowering plants are short day plants, including chrysanthemums, poinsettias and Christmas cactus. If these are exposed to more than 12 hours of light per day, bloom formation does not occur. Other plants require only a short night to flower
  4. Short day plants flower when the day length is less than a critical length (often considered to be 12 hours of light or less). Long day plants flower when the day length is greater than a critical length (often considered to be 14 hours or greater). Day neutral plants flower regardless of the day length
  5. g is used during the flowering period with Photoperiod plants. The light cycle is important because plants need light to photosynthesize. The more light we can give them, the better they are. With photoperiod plants, we are limited to only 12 hours of light during the flowering stage
  6. To maintain vegetative growth, use 18-24 hours of light; six hours of darkness or less. To promote flowering, alternate 12 hours of light with 12 hours of darkness. When switching light cycles from vegetative to flowering, first give plants 36 hours of darkness

Will Buds Mature Faster if I Switch From 12/12 to 10/14

Contrary to popular belief, darkness is more important than light when it comes to flowering. Any plant that requires less than 12 hours of light to bloom is called a short-day plant. T his includes salvia, green onions, and soybeans among many. Any plant that requires more than 12 hours of light to bloom is called a long-day plant Partial shade (the spot still gets 3-6 hours of direct sun per day or continuous dappled sun) American Holly, Azalea, Forsythia (plus all the bushes listed below) Deep shade (the spot may get less than 3 hours of sun per day) Leatherleaf Arrowwood, Inkberry, Japanese Andromeda, Japanese Holly, Mahonia, Japanese Kerria, Rhododendron

To keep vegetative growth, utilize 18-24 hours of light; six hours of night or less. To induce flowering, alternate 12 hours of light with 12 hours of the night. When switching light patterns from vegetative to flowering, first provide plants 36 hours of darkness. To harvest outdoor plants early, cut the time light reaches the plants to 12. The days are the longest during the middle of the growing season - the sun could shine for longer than 12 hours a day during this time of year. You need to find a location that is free from objects or other plants that might block your plants from receiving the most amount of light possible Flowering. 12. 12. Until your plants have 12 hours of complete, uninterrupted darkness, they will stay in the vegetative stage. Once you do give your plants 12 hours of light and 12 hours of darkness, the plants will respond as if the fall season was coming soon, and will, therefore, begin to flower. To summarize Autoflowering cannabis will bloom just fine in 12 hours of light, but yields and overall size will be reduced. It's not the perfect lighting schedule for autos, but for photoperiod strain growers it's a means of gaining familiarity with autos and giving them a trial run. WHAT'S THE BEST TYPE OF LIGHT FOR THE AUTO GROWER When plants were grown on a 48-hour cycle with 15 minutes of red light every 4 hours during the dark period, the critical daylength was reduced from about 32 hours to slightly less than 12 hours.Continuous red light induced a fairly good flowering response

12/12 is easy to explain. Cannabis plants grow outdoors naturally between the months of April to October/November. This means that towards the Sept/Oct/Nov dates the plants will be in flowering. During this time the days get shorter and the nights get longer. When this occurs the plant is under 12 hours of light and 12 hours of darkness 24/0 then switching to 12/12 - The best option if you want to use the 12 hour days is to start your plants under 24/0 or 18/6 while they are in their vegetative growth stage and then switch that light cycle to 12/12 when the first pre-flowers appear. This will give your autos the most amount of growth and the yield will not suffer that much Outdoor plants start flowering late in the summer when the nights get longer, and the days shorten to less than 12 hours of sunlight. This is why it is vitally important to make sure that they are not exposed to light during the night. Even things as common as streetlights or spotlights can interrupt the flowering stage Seit 12 Jahren das beste E-Shop für Beleuchtungsdesign.

Flowering Light Cycle Interrupted- Here's How to Deal with

One of the earliest flowering perennials in the aster family, leopard's bane, shoots up bright yellow daisylike flowers just as spring is getting underway. This eager perennial makes a wonderful companion for spring-flowering bulbs, such as scilla, daffodil, and tulip. To encourage fall flowering, be sure to deadhead its spent blooms You see, the poinsettia is a short-day plant, that is to say, it only blooms when days are less than 12 hours long (or, actually, when nights are more than 12 hours long). So, flowering starts to be initiated starting at fall solstice (that would be September 22 in the Northern Hemisphere this year). Flowering actually begins after about two. Although pre-flowering under 18/6 does not cause flowering it certainly contributes to a decrease in vegetative activity. As soon as you go down to less than 14 hours of light the plant will normally start to flower. 12/12 is the best light regime for flowering and can be introduced as soon as calyx development appears

Flowering Light Cycle for Marijuana The Weed Scen

To bring a long-day plant into flower when day length is less than 12 hours, expose the plant to supplemental light. After a few weeks, flower buds will form. Temperature. Temperature influences most plant processes, including photosynthesis, transpiration, respiration, germination, and flowering Turnips, a long-day crop, require <12 hours of uninterrupted darkness to initiate flowering. Take turnips for example, a long-day plant. Remember the definition of a long day plant: this means that with >12 hours of daylight and <12 hours of uninterrupted darkness, a turnip plant will initiate reproductive growth and attempt to flower

I get it that realizing the 12-12 cycle has four marijuana flowering phases instead of one long phase is more complex than the old-school idea. But just like we humans have distinct growth phases (infant, toddler, child, adolescent, young adult, middle-aged adult, elderly adult, deceased), marijuana does too It's usually recommended ( by lighting companies like gavita)that you veg with less intensity than flowering because the plant is typically receiving 50% or more hours of light per day 18vs 12. This is because a plant can only process so much intense light in a day. In nature a plant would NEVER receive 18 hours of intense light in a day

What is the difference between indica and sativa? - Sensi

If the 12 hours of darkness is interrupted with light, the signal to flower is turned off. The sooner this can be corrected with 12 hours of uninterrupted darkness the better. Once a plant is fully in the flowering state it is very difficult to coax it back to fully vegetative growth but you can still cause plant stress which may lead to. Light Cycle for Indoor Flowering Period. When growing indoors, growers will typically put plants on a schedule of 12 hours of light and 12 hours of darkness (12/12) once plants have reached the desired size during the vegetative period. On average, growers veg indoor plants for 4-8 weeks under an 18/6 or 24/0 light period

Best Light Schedule For Cannabis In The Flowering Stage

When your photo-flowering plants reach the flowering stage, you should actually decrease the amount of light your plants receive down to 12 hours per day. Why is this, you might ask? Contrary to what you might believe, plant growth in this stage is triggered by darkness, rather than light The critical photoperiod for tuberous begonia is 12 hours. That is, photoperiods longer than 12 hours promote the growth of leaves and flowers. Alternatively, when the photoperiod is less than 12 hours, the plants will develop tubers; this comes at the expense of shoot growth and, therefore, flowering Simple light timers like these can change your light and dark cycles to 12 hours on, 12 hours off very easily. From the time flowering starts, you will have approximately eight weeks before it is.

Growing Cannabis As Fast As Possible: What You Need To

The flowering stage is the final stage of growth for a cannabis plant. Flowering occurs naturally when the plant receives less than 12 hours of light a day as the summer days shorten, or as the indoor light cycle is shortened. It is in this stage that resinous buds develop and your hard work will be realized A certain short-day plant flowers when days are less than 12 hours long. Which of the following treatments will result in flowering? A. a 15-hour day and a 9-hour night B. a 12-hour day and a 12-hour night with 1 minute of white light after 6 hours C. an 11-hour day with 1 minute of darkness after 6 hours, followed by a 13-hour nigh There are basically four light cycles aka Light schedules: 24/0, 20/4, 18/6, and 12/12 (the first number is hours of light, the second is hours of dark). You can always adjust the cycle as long as they are receiving more than 12 hours of light a day (to achieve the best results). An example would be 19/5, 16/8, 22/2, etc Photoperiods to start the Flowering Stage of Cannabis. As we said in the previous section the Marijuana plant will enter the flowering stage once there's about 12 straight hours of darkness in a 24-hour photoperiod. Research has proven that less than 12 hours of light does not induce flowering any faster and reduces flower formation and yield The term photoperiod refers to the balance between daylight and darkness in a 24-hour period. You'll often hear cannabis growers talking about a 12-hour (or 12/12) photoperiod, which means 12 hours of light followed by 12 hours of darkness. Some plants, like garden peas, are known as long-day plants, which means they flower when the days are.

Flowering with 14 hours light Rollitu

Short-day plants are those plants that flower when they are exposed to long periods of darkness and short periods of light. For a short-day plant to bloom, there must be less than 12 hours of. The plant has a steady shift in responses to hours of light it receives over a 24-hour period. Foliage continues to form in the plant's vegetative state when lighting follows a 12hr/day format. Some growers debunk the 12hour/day suggestion, claiming 16-18hrs/day is much better for canna growth Most growers of autoflowering strains prefer a light cycle of 20 hours of light and 4 hours of darkness per day. The short growth phase makes it necessary to use this time as effectively as possible and to maximise the growth of the plants. Yet, you may prefer to save fuel bills by adopting a lighting schedule of 18 hours of light and 6 hours. DLI of about 65 mol m-2d-1during the flowering stage •Supplemental lighting increased day length from 12 to 14 hours, which could be used to control vegetative to flowering transitions. If Cannabis sativa is exposed to less than 12 hours of light, flowering is triggered. Natural day lengths change during the year

Flowering Light Cycle Interrupted - Here's How to Deal

Unless the plants are receiving less than 14 hours of light every day, they won't enter the flowering phase. It looks to me like that would be around mid-August in Ontario. If you want the plants to begin flowering early, then really the only option would be to do light-deprivation, which involves covering the plants for 12 hours with some kind. Auto-flowering cannabis plants are unique in that they do not depend on a light cycle to signal when to flower. Instead, they flower on their own time, usually about two to three weeks after germination (average auto-flower seeds can be harvested in less than 13 weeks). Due to their short grow cycle, auto-flowering cannabis plants are a great way to reap multiple harvests in a single season. If your plants are in the flowering phase, 24 hours of light is a big problem. Cannabis plants are sensitive to photoperiods when flowering. In other words, more than 12 hours of light risks confusing your plant and causing it to re-enter the vegetative phase of growth

Using blasts of Far Red at the end of the day - 10 minutes while the lights as on and then to minutes while the normal lights are on - can keep plants flowering with less than the 12 hours of darkness that are normally required Even a quick flash of light can be enough to interrupt the flowering cycle. Grow tents are ideal for light control, but cabinets or closets work well too. Learn more about grow spaces here.. Lights. Provide ample bright lights for under 12 hours per day. Photoperiod plants require at least 12 hours of uninterrupted darkness per day to flower Cannabis Light Schedules Vegetative Stage vs Flowering Stage 2. The vegetative stage is a champion among the most basic bits of the life of your cannabis plant. The vegetative stage is the growing period of the plant. Exactly when in veg, cannabis plants wind up more prominent and taller, growing just stems and leaves How many hours do grow light have to be on. Depending on the plant you will want 12 -18 hours of light. As a rule of thumb leafy plants need less light, flowering and fruiting plants need more. For example, turn the grow light on at 7 in the morning and let them on till the sun is up, after that in a window garden it can be turned off

Tuberous begonia dormancy is controlled by photoperiod. Day lengths longer than 12 hours promote the growth of leaves and flowers, while those less than 12 hours will cause the plant to develop tubers. Tuber growth comes at the expense of shoot growth and, therefore, flowering 4 hours of light, 10 hours of dark, 6 hours of light, 4 hours of dark Long-day (short-night) plants need FEWER consecutive hours of darkness than their critical period. In this question, that means the plant would flower whenever it received fewer than 12 consecutive hours of darkness Regular 'photoperiod' strains of cannabis will basically grow in the vegetative phase if there is more than 12 hours of light provided consecutively. Once the light cycle has shortened to 12 hours or less, the plant will begin to flower. As long as you avoid pollination, flowers will get bigger, denser, and stickier with high resin being. Important Facts to Remember for Flowering Stage. 1. Less than 12 hours light will reduce flowering speed and overall yield. 2. Putting the lights on during the 12 hour dark period even if it's a short period will harm your plant and leave them stuck in the vegetative stage. 3 These plants thrive on less than 12 hours of light a day. To the extent that they can create larger buds in a shorter growing timeframe than many typical weed plants. They are small in stature, which makes them perfect for a clandestine grow. The potency of these plants has increased markedly in the last few years

What light cycle do you prefer for flowering 12/12 or 13

Some flowering plants can take less light than others. fooling such a plant into bloom at other times of the year by putting it in a dark closet each day after it receives 12 hours of sun for. So, when the days (number of hours of daylight, that is) are 14 hours long, both chrysanthemums and spinach will be stimulated to begin flowering. Chrysanthemums will initiate flowers because the day length is shorter than their critical day length of 15 hours; spinach will flower because the day length is longer than its critical day length of. Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these. Autoflower seeds grow small, easy-growing plants that you can harvest in 10 weeks. Great for new growers, small spaces, or multiple harvests per season

For instance, giving the plants 18 hours of light should result in 6 hours of darkness afterward. Consequently, giving the plants 12 hours of light should also give them the same amount of darkness. Experienced growers who can effectively maintain their autoflowering plants can even boost their light schedules to 21-3 cycles I am very happy with this product. I have ONLY used this light for the Flowering Stage of my medical cannabis growing, which I have not finished yet. The vegetative state was with flourescent lighting. The plants took very well to this when switched over. I'm using 12/12 hour light/dark schedule and the buds have responded well during this. In this experiment it means that every hour of light can produce one new cell from one cell. Let's start with one cell and two light cycles 24 hours and 12 hours: 24 Hours-. 1. day - 1*24*1 = 24. 2. day - 24*24*1 = 576. 3. day - 3456*24*1 = 13824. 4.day - 13824*24*1 = 331776. 5.day - 331776*24*1 = 7962624

Short-day plants, such as chrysanthemums, kalanchoe, azaleas and begonias, will thrive on less than 12 hours of light per day. In fact, these plants must usually go through a series of even shorter days before they will set buds and flower. Long-day plants require 14 to 18 hours of light each day. Most seedlings for vegetables and garden. I have reverted plants that were in the flower cycle for up to 3 weeks back to the veg cycle with no problems other than losing time. All you have to do is change your flowering light cycle of 12 hours on and 12 hours off to 24 hours on for about 10 days. Your plants will start reverting back to the veg cycle Increasing the light cycle slows down the flowering time but also increases yield. Not all cannabis strains require 12 hours of dark to flower. Some can flower at 11 or even 10 hours of dark, but we use 12 hours because this satisfies practically all strains and ensures that a cannabis will flower regardless of genetic variances Using light deprivation to stimulate flowering in your cannabis plants — which happens during a 12-hour light, 12-hour darkness cycle — is helpful for many reasons. Light dep, as it's commonly known, can help outdoor and greenhouse growers avoid bud rot, powdery mildew , and get two grow seasons in most climates Thus nurserymen can get short-day chrysanthemums to bloom in summer by keeping them in the dark for more than 12 hours each day. Poinsettias can be induced to bloom if they get 10 or more hours of darkness for a week or so. Indoor lighting and the light from stree

How Day Length Can Affect the Flowering of Plants Home

When switching to the flowering stage, auto seeds develop better, bigger and faster with 18 hours of light but they can make do with 12 hours. Bear in mind that autos growing with only 12 hours of light may experience slower growth and may take longer to mature. Also, most of the times, less light also means less yield when growing autos The autumnal equinox is near September 22 in the north and March 20 in the south. Light schedules intended to induce flowering simulate the light around the time of the autumnal equinox, with 12 hours of light and 12 of dark. Winter months occur when a hemisphere is pointed away from the sun 12 24 36. per page. When planting partial sun perennials, consider the amount of light the specific area receives per day. Partial sun means the plants get at least three to four hours of direct sun a day, but less than 6 hours of direct sun. If the plants are under a tree and receive filtered light most of the day that can also be partial sun

The Importance Of The Dark Cycle In Cannabis Cultivation

How to Use Light Deprivation to Control Cannabis Flowering. Light deprivation as a practice is more or less straightforward. However, your growing environment will dictate the exact protocol you need to follow to ensure a successful harvest (or several!). Indoors. Indoors, light deprivation is the name of the game 8 /22. Known for dense foliage, unusual purple flowers, and its ability to spread, Aristolochia macrophylla, or Dutchman's Pipe, is a fast-growing shade plant that can reach heights of up to 30. Flowering (12/12) Once our cannabis plants are big enough, we can switch the lighting schedule to 12/12. This means they have an even amount of light to dark over a 24 hour period. Sometimes growers give even less as a way to further save on bills, but 12 hours is perfect

20 Small or Dwarf Flowering Shrubs (With Pictures and Names

Light left on for 48 hours in flower. I just discovered a huge mistake that I made. I have 20 female all in week 4 of flowering. My light cycle for them is 12 on and 12 off. I was moving something around and I hit my light timer which turned off the auto mode to the light. Today I needed to go in the room to (while the lights should be off) and. FLOWERING STAGE. Finally, the flowering stage (6-8 weeks, 12 hours sunlight). When the plant gets less than 12 hours of sunshine a day and the days of summer become shorter, or the light cycle is reduced indoors, flowering will occur naturally. And soon, those sweet, resinous buds will grace you with their presence

Fast Flowering Cannabis Strains

Many equatorial varieties require 12 1/2 or even 13 hours of uninterrupted darkness (each day) in order to force them into flowering properly. Most plants are less picky, and will begin flowering when they begin getting 12 hours of uninterrupted darkness every night (and always at the same time each night) The classic light dep schedule is 12 hours of light and 12 hours of dark, with the plants being covered at 7 p.m. and uncovered at 7 a.m. This schedule requires good ventilation, so some farmers choose to uncover their plants at night. Others simply cover in the morning before the sun comes up, uncovering a few hours later In order to begin the flowering process, photoperiod weed plants require the amount of daily light to be decreased to 12 hours. This change in lighting then causes a chemical reaction in the plant which signals that it is time to start flowering The critical night length, or the amount of time required for the photoperiod response in Cannabis to occur in order to stimulate flowering, is between nine and 10 hours, which corresponds to 14 to 15 hours of daylight, but it varies by cultivar. To induce Cannabis flowering in greenhouse production, plants receive 12 hours of darkness

University of Delaware Cooperative Extension, Kent Co

For example, a long day for many herbaceous perennials is 13-14 hours or longer of light, and a short day for poinsettias is around 12 1/4 hours or less. Some plants will flower under a range of photoperiods but flower quicker under some photoperiods than others This cap must be placed over the plants every evening at the same hour to make sure they don't get more than 12 hours of light for each flowering day. Cardboard boxes, blackout photography curtains or camping tents are good materials for building a forced flowering system. A well engineered blackout cap can also be hung to cables and. The bloom period begins with the appearance of the first flowers, about 10-15 days after switching the photoperiod to 12 hours of continuous light followed by 12 hours of complete darkness. Autoflowering strains do not depend on photoperiod to develop flowers, for they automatically start flowering 2 or 3 weeks after seed germination

What is Artificial Light? - Definition from MaximumYield

It's all dependent on the genetics, your light strength, and more. Also, just because it is smaller doesn't mean it will make less weight - a more accurate statement would be 'they are generally smaller, and can yield less under similar conditions'. I've seen an auto-flowering yield 8 ounces, and a 12/12 yield an eighth At 50,000 lux, a double ended HPS grow light emits 650 uMols of light per second and about 28 Moles of light during a 12 hour flowering light cycle, or 42 moles of light during an 18 hour vegetative phase light cycle. That's more or less on target with what cannabis plants need to grow While autoflowers don't need to be introduced to a specific photoperiod like regular cannabis strains (the 12 hours of undisturbed light vs. 12 hours of undisturbed darkness), autos will give best results upon harvesting when they have been bathed in a minimum of 18 hours of light every day

Philips 46 inPlant Light Indoor Plant 1500W LED Black Greenhouse

The flowering stage of a cannabis plant occurs after light exposure is reduced. Where cannabis plants will stay in veg forever if they're kept under light for 18 hours a day, switching the light cycle to 12 hours of light and 12 hours of darkness will initiate the flowering stage Week 1 Flowering. Light Quantity - 100% (600watt HPS) Light distance - 1.6 ft (50cm) Light Duration - 12 hours; Temperature Day / Night - 77ºF / 64.4ºF (25ºC/18ºC) Humidity level - 70%; pH level - 6.0; EC - 1.2; By reducing the light duration from 18 to 12 hours, the plant 'thinks' the fall season is coming and begins to. light. Short-day plants form flowers only when the day length is less than a critical minimum, usually about 12 hours in duration. Examples include spring and fall flowering plants, such as chrysanthemum and poinsettia. Long-day plants form flowers only when day length exceeds a critical minimum, usually more than 12 hours Most cannabis strains need equal spells of dark and light every 24 hours before they will begin to start budding. If the plants are exposed to more than 12 hours of light every 24 hours then they will continue to grow but not flower or form buds. Bummer! Not so with auto-flowering cannabis. These suckers will start to flower a few weeks after. Flowering in hemp plants is triggered when the dark period (night) is approximately 12 hours long. When the dark period is shorter than 12 hours, and the light period (daylength) is longer, plants remain vegetative and do not flower. Closed growing environments, such as a grow tent or blackout cover, allow you to control photoperiod

They require more than the critical duration of light to flower (usually 14-16 hours). The light period is very critical in LDP plants. Prolongation of the light period or a brief exposure to light during the dark period boosts flowering in these plants. One usually does not find LDP plants in places where the length of a day is too short 200 to 280 nm: ultra violet range extremely harmful to plants, highly toxic 280 to 315 nm: has harmful ultraviolet light causing plants colors to fade. 315 to 380 nm: range ultraviolet light is neither harmful nor beneficial to plant growth. 380 to 400 nm: light spectrum starts to be visible. Chlorophyll absorption process begins. 400 to 520 nm: the range includes violet, blue, and green bands I have 3 tents, one bigger than the other. 1) is my seedling/germination box 2) is my med tent 3) is my veg tent which will also house my flowering ladies. I had my seedling box on a 16-8 but box 2,3 on a 18-6. i read that less light will encourage females. I also have a blue dominant spectrum light in my seedling box
