try to get the temps from 75 to 90 degrees F. the plants can handle 100 plus temps but not for too long

oh and when you measure your temps inside your box/tent whatever. you should try to measure the temps at the plant canopy under your light. just a FYI. and like peeps said if you can exhaust from your hood that should drop temps dramatically. good luck

how many cfm does that 5inch fan move? i can barely get away with my 600 in my dr80 (2.3 x 2.3 x 5) but the trick is good active intake. after spending 200$ on my 6inch extractor fan i went out and bought a 2 cheap bathroom exhaust fans , 100 cfm each, for 30$, wired them up with and wall socket plug and just set them outside my tent with the exhaust routed into the tent via 4inch ducting , 6 degrees above ambient with 600W in a 25cu.ft tent

[FONT=&quot]Daytime[/FONT][FONT=&quot] conditions should be 70-80 degrees without co2, 80-90 degrees with co2 until the last two weeks when daytime temps should be kept between 70-80 and co2 can be reduced to adjust for the lower metabolism. Night temperatures should be kept above 60 degrees to prevent stress. It is preferable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation.[/FONT]
 [FONT=&quot]I find that low humidity causes stress on plants. I recommend 50-60% humidity until the final 2 weeks of flowering. At this point, the humidity should be lowered as much as possible to encourage the plant to seal and protect itself with additional resin. (I am able to get the humidity to go as low as 31%) I have been able to frost things up considerably this way. The higher humidity levels prior to final ripening reduce salt levels within the plant tissue and encourage healthy, lusher growth.[/FONT]
