Why, exactly 12/12?

[hyroot]

With so much rep you'd think you'd be right , but your not friend. The only type of Cannabis you can make flower under 24/7 lights in an autoflower or ruderalis and you can flower using an MH light too by the way; I use the MH light for the first 2 weeks of flowering to keep the stretch to a minimum because the HPS spectrum increases the stretch those first 2 weeks and by the end of those 2 weeks she's already started to bud, every time. I've seen growers half way through their grow have to use the MH light because their HPS broke or whatever and they have finished their grow just fine, not as well perhaps but a good harvest nonetheless. Very few strains wYould flower at only 8 hours of darkness (if any); most will flower with 10 or more, 12 to be sure.

You can flower any strain in 24 /7 I have done it on accident then 2 more times to figure out how. Poly is right. Its about spectrum. All you have to do is add enough infrared at 760 nm and you will see flowers forming within 15 hours. Add two wave point coral wave t5 bulbs. They have 35% peak at 760 nm and has IR from 740nm to 800nm.

Texas A&M Agricultural site has several studies on the matter.

my first where accidents too.

Supposing that you could which I still think you can't regardless of your claims; why would you want to do that?? Wouldn't constant exposure to light erode the trichomes and result in a less potent product? Some growers like to leave them in the dark for 2-3 days before harvest for that same reason to allow the trichomes to be a their full potential and in fact they "recycle" every day; degrading during the day and multiplying at night. Not to mention the costs of having the light on for the whole 3 months of the grow 24/7 IF you could even flower that way; I don't believe it sorry, show me proof and I'll admit I was wrong but until then I'll go with the science that I have seen to be true.

P.S.: If you veg a plant long enough she will show pre-flowers all throughout; this is not the same as creating buds mind you. Also a LOT of strains out there are crossed with a ruderalis at some point to either keep them short or for some other traits, maybe the strain you grew that had this happen had been crossed with a ruderalis and that particular phenotype if kept long enough will start to flower regardless of how many dark time she gets. It is possible. BUT a pure Sativa or a pure Indica I highly doubt this will ever happen; she might pre-flower profusely but she will not produce buds until the time changes. IMO.

well buddy i like your guff.

but yeah for the most part you wouldnt want to do that, well not 24 hours light at least yeild will more than likely suffer, but no im talking buds, not big buds but buds none the less..

yep im still trying to figure out why pros put there shit in the dark for a few days....... its pure nonsense thats all.

anyways i dont think i have any pics of the plants but they where put into 12/12 soon after it happened because it was an accident. i could recreate but uh right now my grow is all tiny for personal reasons ill be picking back up soon enough(2 or 3 mo.) and see if i cant make it happen with some pics.

as far as BF bluecheese having ruderalis, i dont think so its pretty sat. dom.

Whoop!!!!!

I dont want to make them flower on purpose while in 24/7. I was trying different bulbs. It just happened. Now I know what light not add during veg.

I put mine in the dark for 2 days prior to harvest. For one reason much more trichomes. When plants sit in the dark and the light does not come on when plants are used too. The plant knows its at the end so its calyx swell up with thc beacuse the plant is trying to push out seeds to make its lineage live on. Since its not pollinated. No seeds form and the calyx swell that much more. Buds become more resinous. Trichomes form in the dark.

imvho, i don't see how a plant will flower under 24 hours of light.. a plant will only flower once it receives enough dark hours... it's the amount of dark hours built up which triggers flowering hormones, nothing more, nothing less..

par, k or anything else has nada to do with when a cannabis plant will flower..

and the reason people use 12 / 12 is simply because it's easy, nothing more, nothing less.. yes, some plants will flower with say only 10 hours of darkness, and some will flower with 14 hours of darkness, but all plants will flower under 12 / 12, which is why people stay with it..

i disagree with this as well.. firstly, i always like to look at nature.. what happens in nature to give plants 48 hours of darkness?? nothing, there is no 2 day dark period ever during fall outdoors that i know of..
i've tried the 48 hour darkness thing a few times and can honestly say i saw absolutely no difference in tric production.. it's one of those myths that high times likes to push like flushing your plants will make them taste better..

plants can rest in some types of light and still build up hormones, at leas this is my theory. i really have no reason to lie.

You never tried it. Or you would see it works.your just going by what some one has told you. On your next batch. Put one in the dark and the other not. I guarantee you will see a difference. I did that recently again to prove to a friend that it works. With flowering. If you talk about nature. Look at other places in the world where they get infrared from the sun. We dont in the u.s. Accept in hawaii. There its flowering time year round. Cant veg out door in Hawaii. Try using more IR lighting and see what happens. Or google one of te studies at texas a&m, oxford university or washington state.

anywaaaaaayyyy....back on topic.

Any of you try 12/12 from clone with a bed full of clones say 15 days of veg?

 

[hyroot]

I have no veg and with 2 weeks veg. Both pulled 3 zips per bed. each bed was a 91 quart sterilite tote. Did the soma style bed too. 2 beds took up a 24 x 30 in. It was all sky walker. Buds were like 0.8 g dry. That strain s not a good yielder. A chunky kush would do better most likley. I think 12/12 from seed would yield better. In a bed that would be a pain in the ass if there were males or hermes.

How many plants were you growing to get 3z?

 

[hyroot]

It was either 15 or 18. 3 Rows of 5 or 6 in each bed. It was a few years ago 2 totes per 400 watt hps

 

[Fresh 2 De@th]

with so much rep i am right. i dont care what you have to say of course plant will flower under MH(duh has nothing to do with what i said) but it will affect growth.

if you really dont think you can flower under 24/7 i can tell you how if you would like. regulars can be flowered under 24/7 if given the right conditions, believe what you want but it all comes down to controlling the hormones through the light and other things. seriously dude im not lying.

hmm, i was just saying the same thing about a month ago in another thread and some wouldn't believe me. i even posted threads from other boards to prove my point but it still went in one ear and out the other.

well thats the way it goes sometimes, some people act like there heads are hollow

 

[Fresh 2 De@th]

what was crazy was dude went all around the evidence and kept insisting that it was an auto. in the thread the plant was a clone he had for 2+ yrs, and anyone knows an auto life cycle is no where near that long.

Plants in nature:

Seeds germinate in the spring (cool, not humid, longish days- ~ 14-16hrs).

Seedlings develop under summer sun- warm, humid, longish days- 14-16hours).

Plants begin to flower under a return to cooler weather combined with shorter day light- roughly 14 hours

Plants finish under cool days and cooler/cold nights.

Depending on where your strain comes from will have some effect on this. Indicas may only get 10 hours of daylight and cooler temps, Sats get more light and warmer temps. Hybrids will depend on which strain is dominant

Indoors

In mid-late August I germ in a window sill using a clear humidity dome. Once seedlings reach ~ 1" tall they are transferred to the tent under low intensity lighting @ 20/4 until 2nd set of leaves develop, then lower light cycle to 14/10 (and height of bulbs to canopy). By ~3rd node, amount of light increases

There is little difference in growth between 18 & 14 hours, and since electric is $$$, well...

Flowering

This can be induced simply by increasing % of PK > 500ppm (no light change required): reverse pre-flower by < ~ 400ppm (this can help cull the males) then return to lower ppm, until plants are ready to flip. At least it does using Hydro-Research VEG+BLOOM, an awesome ONE step nutrient

I begin with 14/10 (~2 weeks), then 13/11 (~ 2 weeks) and finish under 10/14. You can check out my completed journal to see that this works.

So did it not make sense for you in the end to grow more plants just smaller?

that depends on strain. the ones that got vegged for 2 weeks had more buds but smaller. Ironically the ones that did not veg had much bigger tops. I got the same yield on both. There might have been a difference of a few grams give or take.

Its really trial and error. I do think the ones that did not veg, grew a much better root ball. if veg i think it takes longer for the root ball to develop than if flowered right away. like 12/12 from seed
