Just teasing you Jimmy.....you said that so innocently. Ideal room temp is about 70....keep under 80 if at all possible.....opie's stretching at 85 imo BUT the REAL key is this.....(shhhhh) when the leaf surface temps go over 80 degrees (usually at about 85 degrees room temp or so depending on ventilation, how close your light is etc..) the plants growth will slow down tremendously. Photosynthesis drops a HUGE amount (in fact almost to 0 if I remember correctly) when leaf surface temp exceeds 80 so while your plants may seem fine-ish at a higher temp.....it behooves both you and your plants to keep temps down.

You can buy yourself a cheap $20 handheld temp gun and that will give you an accurate reading of your leaf surface temps.
