this is my first time growing i am growing ak47 using a hydrolab i started to flower on the 07/05/09 i am just wondering when the plants go in omplete darkness do i still have my fans on 24/7 the tent is 1.2 meres square and the fans that i am using is 2 clip on sizes are 6inches 1 cooling the lamp and 1 pushing air around the tent i am also using a dehumidifiyer any help or advise would be great thanks.

Yep. Keep your fans on 24 hours a day. When the lights are off humidity creeps up so it's even more important to keep it moving around and refreshing it often.

i leave 1 fan blowing air around all night as i read somewere that the plants still breath when sleeping just as much as awake so they need it really bad, u dont want stagnent air in there that will only complicate things and reduce crop size , i have got 2 extractors aswell and would probably leave them on as well to put fresh air flow up but cant due to them sounding like airplane engines lmao anyway i would say get as much air in at sleep time as they have in day cant do any harm can it!!

anyway good luck dude

E2A: perhaps get a bigger fan to help blow around harder aswell they love them lefas blowing around lots!!!

thanks mate will do

thanks mate changed 1 of the fans straight away to a 12 inch just to puch a bit more air around once again thanks.

think im the only person that dosent leave any on at night by the sound of it, the reasons are my outake fan is to bloody loud and id leave one of the little fans on but im paranoid about a fire starting through the night, there only those 6" clip on fans and i always think they will burn out somtime or another, god im para about fires(and yes i do have an alarm and extinisher). tbh ive not noticed anything bad happening to the plants, i leave extraction on till like 1am wehn i go bed and the fans or on again at 10am, it hits 90% humidity though but apart from that they look fine(touch wooed).

That will be a big problem at some point mate, late in flowering it should be under 50% to try an avoid budrot and it should never be as high as 90%, i try to keep it at the 60-65% region at the most at anytime and then drop it at half way through flowering to under 50%.
