You want the 12/12 bro. THC production requires the proper quantity and quality of light. It seems that none of the biosynthetic processes operate efficiently when low light conditions prevent proper photosynthesis. Research has shown (Valle et al. 197
that twice as much THC is produced under a 12-hour photoperiod than under a 10-hour photoperiod.

thanks topfuel...maybe because i never had any nutes from veggie to flowering till late in the 5th week of flowering i picked up nutes.. so its been about a few days since its first dosage...alot of people told me they have seen people use 23 watt cfs using nutes and still get a good ammout if growed with the proper nutes

Hmm. Then 1 on, 23 off should produce enormous buds. You should try an experiment and let us know.

Just my 0.02¢....photosynthesis only occurs (in a cannibis plant, some plant are different) during daylight or lights on for indoor growers. 12/12 is the adopted light cycle in the cannibis community as it first stimulates the change from vegetation to flower and at the same time keeps the plant in that photoperiod as well. I've ran tests at 11/13 and 13/11 and found no significant difference in ield. The only trick I've been taugjt and still use is to go lights out last 24 hours before harvesr or a 6/18..it stimulates plants into releasing all o2 and h20 to absorb all available co2 in a survival tactic. It doesn't do much but its help fill out n dense my buds up.
On a side note, I'm still amazed growers compare lumens when talking about lights or even foot candles as well...those are measurements of the HUMAN eye. Plants use light for photosynthesis, lumens have nothing to do with the amount of photons absorbed into the leaves of a plant. PARwatts are aspecific measurement for plants. Lumens are just how bright a human interprets a light..

The topic of this thread is a bad idea...a little extra dark may ripen them a few days earlier I hear but def won't increase ur size....that's just crazy talk.....don't try every slick trick n get bud big n fast moves u see on the net....stickbw the basics n grow an average healthy plant to start w with abnormal average basic set up and schedule (feeding and lighting)....once u get that down then shoot for some advanced growing techniques...one step at a time...think abt it...more light = bigger plants n bigger yields... why would u wanna take that away from em

well im assuming my cfl setup is going to do very well in this closet knowing i have 10 cfls shooting out lots of light ...to be honest compared to my old 400 watt hp light cfls kick its ass.....it deff puts out more light and blinds me but the 400 watt hp dont do nuttin like that so im deff sticking with my cfls....and to top it off they give off no heat and save on power and if you youtube cfl grows ull see alot of people getting some nice ammounts off cfl grows....but hands down from the way the light output is and heat difference compared to my old 400 watt hp light im sticking with my cfls
check this link on a cfl grow ...kickass dont talk down cfls now

heres another guy talking about how good cfls are and gets a great yield

Nice and cheap...the way we like it.
I got my 23 watt cfl spots at the dollar store.
Just for clones and added to my LEDs when the heater trys to come on.

I have heard of people using Deep Red light treatments (660nm i think?) for 30 mins after lights off.. The research is still incomplete, but the premise is that the sun puts out very intense red light at sunset.. which causes the plants to hasten into their night time activity. This is the theory anyways.. the hypothesis is that the deep red treatment will allow your plants to reach peak night time activity much faster.. allowing you to decrease your night period by up to 2 hours. The experiments are still incomplete.. but I am anxious to see the results! This could potentially cut a week or more off of harvest time! Totally cool!

Let me guess. Bmeat told you to do that didnt he?

I don't have to you tube it...I do it in real life...
...my space is a lot smaller than a closet n I have a lot more than 10 23 waters...I put that on my seedlings...
...and here's my seedlings View attachment 2509341...and some finished stuff View attachment 2509344
I've got some stuff on you tube..."cfls....kush"...have 3 videos...2 of those bulbs on my seedlings are 42 watters
