photoperiod manipulation for larger yeild

not for sure but I think that the 72hrs of darkness is not for growth but to help the plant flush of chlrophyll since there is no light the plant stops making it and starts to also feen on reserve nutrients, also flushing it of other trace minerals

There was a thread similar to this not too long ago (started by myself I believe) I was wondering what people thought about me changing the light cycle to 12:30/11:30 and Doctor Cannabis mentioned that during the night the plants produce trichomes, which in turn during the day protect the plant against UV rays/heat and what not. The last 72 hours in dark is for potency/trichome production etc.

Island green guy thats a nice BOX of money, how much was there

i put my plants on 10/14 10 light 14 dark for the the last week of their life and so far have seen amazing results

In last months High Times they had an article about a "master grower" somewhere in Cali. He sets his lights to 13 on and 11 off about 2 or 3 weeks into bloom for about 2 weeks, he says the extra light along with a bloom enhancer like Big bud or something like it sends the buds into overdrive. He also kills the lights for 72 hours right before harvest, says it increases flavor and coloring dramaticaly. I don't know about the 72 hour thing, that kind of scares me, but I'm going to try the 13/11 thing.

you mind pullin gout the article in wich you read this im interested now, as far as the 72 hrs light off at the end ive done it it does increase some thc but not significantly, but the taste changes. Also 48 hr darkness going into bloom speeds things up by about a week as it sends them into bloom really quickly. Ive done 11 on 13 off for the last 10 days before as soon as i started my flushing and ive had good results.

im not a master grower but wouldnt you want to increase the dark time and increase the day time? so the plant think oh shit im losing more daylight. and i dont think the 72 hour thing would be good .. what about mold and stuff?

so to do the 10light 14dark thing do you change its off time,, or its on time?

Id say off time.

by keeping your humidity levels low during those last 72 hrs is the key to success not only does it prevent bacteria and mold but it also helps dry out the soil so its not so heavy to throw out and helps with the drying of your nugs as the plant gets alot of its juiced dried out, making curing much more easier and faster.

interesting thread

Going to check my crop today. This durban is taking forever for the trichs to turn. everyone that sees is wants to wack it down now it's sugary as hell but no amber ones yet. as soon as i see enough amber its in the dark for 72 hrs. FYI didn't forget about it just taking forever!!!!

everyone that sees is wants to wack it down now

How many people looking at your plant(s)? Did ya miss the first rule of growing? You should atleast charge admission that way when your plant(s) get boosted you'll have a little flow to make up for it

You do not want a fast dry or a fast cure unless you are a commercial grower. The slower the cure, the tastier the buds and the stonier they become. You want to cure in a jar for at least 1 month.
I have weed that has been in jars for minths and it keeps getting better and better, but there is a cut off point.

just my 2 brothers. i don't have a big sign up "hey killer pot growin over here"

Anyone try non-24 hour photoperiods? Like 12/4 for veg(1.5 days per 1 Earth), or 20/12 for flowering(.75 days per 1 Earth)?

good question tea!

I'm experimenting with 12/4 veg.

Now you have to keep us posted!

I've heard about the 72 hours of darkness at the end it is supposed to increase resin production. there is no possible way to increase potency that all depends on the genetics of your plant. you cant take shit and turn it to gold. i personally have increased my light cycle to 14/10 after seeing it in one of the urban growers vids and it was said to give about a 10 % increase in yeild and on a pound thats what an oz&1/2. something like that but smaller plants and smaller number of them you prolly wont notice the difference. But i totally agree with the increase in light the last 2 weeks and 72 hours of darkness but i flood my plants the last few days and then let them sit for 2 days so the soils dry by the time i hack. Every grower has there own tech's and what works for them. You never know thats the beauty of cannabis you make it your own and dont have to follow the rules

When did you switch to 14/10,
and have you noticed anything peculiar since then?

i had one guy tell me to do 14 light 10 dark for grow. then 14 dark 10 light for flower....
