ok, first time grower so obviously ima first time co2 use.anyway since i put co2 in,like a week after i started 12/12 i cant keep the heat down for nothin! Im like @ day 50 of 12/12 and the temps sometimes get as high as 85 if i dont keep the central air going all day.the humidity is perfect.so at this stage in the game what is the highest i can let the temps before the heat is hurting my plants???:?:
 
i wouldnt let them go over 85 even with co2. the reason people run higher temps is because it helps the plants metabolize co2 faster and in more volume.
 
Plant growth processes retard at 85 Fahrenheit .. growers of peppers, geraniums, tomates etc all respect the 80-85 degree Fahrenheit limits for their crops ..we should too.

In fruit crops, the flowers are often the most effected, resulting in smaller flowers/fruits

Some strains may take more heat via genetics

Watch your plant growth rate if your HVAC limits force you to go higher.

Watch for other stress induced diseases and pest if you raise the temperature

Food for thought ... consider lower wattage lights (700/400?). You might find you can get about as much light as you need with lower wattage when used at the proper light to plant spacing.

what are you talking about?!?!/ we arent growing peppers or geraniums here bro lol maybe you haven't noticed but cannabis grows very different from other fruits veggies and plants. so making comparrisons like that is foolish at best.
