Im using large CFL's, 250watts(true), in soil and my temps for veg range from like 81f - 87f with a pretty constant 55% humidity. My flowering room has temps that are close to the same, mid 80's but the humidity drops below 50%. I want to know if these temp for flowering are okay or if I need to take measures to drop them

edit: My plants that are vegging are doing extremely well. I suppose I should post pics

Hey chasmtz,

I've got a 400w that runs around 75-79 and humidity 40-50. I've personally haven't tested higher temps but I've read after 85 degrees growth starts to slow in general( take that with a dash of salt)
But your humidity looks good you wanna keep it 40-60 during flowering. I like to keep mine lower than 50%. Personally id try to manage this temps, but a grow isn't impossible without it.

With that said, pics would be great :eyesmoke:

my fans are weak. my only air flow is one 4" (170cfm) blowing in and one sucking out. these would be perfect if i didnt have filters slowing them down. I think i need 6" fans to circulate fresh air. I have a space thats 7'l x 7'w x 6'h.

Use both your fans as exhaust and have passive intake.

I've run 250w CFL (+96W T5) in a sealed environment, I'll wager that your ambient temps at intake are high to begin with.

anyone here actually flowering marijuana plants have a thermometer and care to share the readout? I'd prefer someone who has decent buds to share :). Just want some average temps guys, thanks

plants start slowing down about 95' or so. just something ive read but than again high 80's or low 90's arent that bad if you keep the co2 up. i stay in the high 70's to low 80's in flower with a very low humidity ranging 25-35%

CO2 is the answer for high temps in the growroom it allows the plants to photosynthesize, even at temps over 95. Seen it first hand.
