Found a grow thread with no info on grow and no pics. 10 pages long with minimal views. That one?
RUI must be lying to me. My bad.
90 degrees to hot for a plant?

The following information is straight from Greg Green's "The Cannabis Grow Bible"
Cannabis is a light demanding plant. Professional growers keep the light on their plants using the 24/0 photoperiod for this reason. Plants that grow under 24/0 flourish and do not need a quantity of darkness in order to rest and perform photosynthesis properly. Plants that are grown in optimal conditions under 24/0 light regime grow vigorusly and the benefits of a 24/0 photoperiod can be seen actively in the results. More nodes are formed, more branches are created, leaf numbers increase, the plant is growing at its finest.
Some growers opt to use 18/6 as their photoperiod. This is 18 hours of light, six hours of darkness light regime. Under these conditions the plant will grow quite naturally but not as vigorously as the 24/0 photoperiod.
The 18/6 photoperiod expels 3/4 the amount of light that a 24/0 photoperiod does. Although this does not mean that a plant produces 1/4 less leaves,branches and nodes under the 18/6 photoperiod, it certainly does show the correlation between light and cannabis growth. As we have said already, cannabis is a light demanding plant. There are no problems associated with 24/0 and although some have attributed cannabis sexual dysfunction (the hermaphrodite conditon) to 18/6 photoperiod these problems are actually the result of heat stress.

All proteins are synthesized durring the krebs cycle mostly at night (photosynthesis is used to create ATP used for the formation of glucose and startches - all other molecular functions take place without photosynthesis utilizing the breakdown of these sugars). I don't care what book you read it in but 24hrs is never the best way to go economically or for the plant. I can reference many better bio books than the Marjuana grow bible. That reference doesn't specify what heat stress it is talking about either. little to no fluctuation between night and days temps if a form of heat stress created by 24 hr lighting - is it talking about this heat stress? Or high heat? Or high humidity or lack of humidity due to constant unchanging heat?
Arguing with you is like like talking to a stubborn kid. Turn out i have 26k veiws on a single grow thread with actual material. Can i just post "Unsubscribed" and hope my point is more valid? I just don't understant why you purposefully lead people into make poor descisions - i remember when you told me that spraying bone meal solution as a foliar feed (a non mineralized forumla that the plant has no possible way of absorbing) would be benefitial to my plants. Get a life dude.
/e and what growers set their lights on 24 hrs? I don't know a single one except those playing with autos.
I never mentioned to ask - do your plants look stressed? Are they drooping or showing any other signs of stress? High heat can lead to stress but does not guarantee it. If suddenly all your plants at 90degree temps and flopped completely over then definately work at lower the temps. If they look fine they then are not very stressed.
