optimal temps....

[BUDSLiNGER]

Alright guys we have allot of opinions on this and I can say I think my girls enjoy the temps up around 90, i havent noticed any ill effects, Ive had grows at 70 degrees and also kept them around 90 and tricome production seems higher at the higher temps.... whats the real story?
lets see some growers opinions ???

I'd like to know this too! My 3'x4'x5' cab has a light exhaust, an exhaust, incoming vent, as well as circulating fan and it still gets close to 90 at the end of May. It gets rather warm here, and I see the next grow being done at night. I have at the moment I think nine plants, all of them neglected or tortured at one time or another, but doing pretty well, even with my interference.

My light can be placed within inches of plant tops w/o damage, the air intake is 90cfm as is the exhaust. The ballast is mounted on the exterior. Anyone have any suggestions??

I've heard that lower temps, 75-85, or better for veging and early flowering and higher temps, 90+, and low humidity are good for late flowering. THe high temps and low humidity cause the plant to produce more resin to keep itself from drying out. You can also add a UV light to intensify the effect. When i flower my first grow(seedlings now) im going to get the humidity down to 30 and add a uv bulb.

At temps above about 85F MJ has difficulty uptaking CO2.

And water has a hard time holding Oxygen at higher temps as well - for those using any non-soil techniques...
