temp's at the top of the canopy

[Mellow Man]

I read in the faq guide here that marijuana does best with temps of 76,78 the top of my canopy of my plants are reading 82 is this bad should I try to get the temp down or is 82 fine?............thats with the lights on of course,and in the night my temps drop to about 70 is this decent for a tempature reading both for lights on and lights off?

82 is fine, and 70 is ok for a night time temp. Without extra Co2 output your probably alright up to the mid/high 80's so don't worry, also if your thermometer is in direct light it is probably reading radiant heat.

I Would agree.. 82 isn't bad at all.. i often can go 90-92 degree depending on how my fan is positioned. 82...ish... is my general canopy temp.

There is a difference between best and acceptable range in temperature. Different growth cycles require different environmental climates so your temperature and humidity can vary to keep up with the plants cycle. That temperature range is just a good number to shoot for. Experienced growers will very the humidity and temperature to match the cycle of the plant and get tremendous results.

Dude you where right! my thermo was pointed upwards taking the radiant heat lol,so I turned the Thermo on the other side away from the direct light and temps dropped down to 77....cool :thumbsup:

I have done the 95 degree thing too.. and it was awesome... but.. if any bugs find out you're growing at 95 degrees.. and they decide to come over and check your shit out... YOUR FUCKED...
