Oh no don't take a break yet Doc, lol
I have a question about temps.
When you refer to temps, are you referring to the temp right at the top of the plants, soil temp, or the ambient temp in the room?
All of the above:
For general health of the plants, canopy temps are very important.
The Ambient room temps are important, especially if you have really good air circulation in the room, as ambient temps will equal "THE" temp everywhere except directly under the lights.
Soil temp is important also. Warm air due to a heater in a rooom with plants on a stone cold cement floor will do some really funny things to your plants.
You've got to balance everything out. Keeping the plants on raised trays mean the roots will be slightly cooler than the ambient temps in the room, due to evaporation. Cooling the lights will keep canopy temps close to room temps.....you get the picture.
Ideally, the ambient temp is "THE" temp. But for that to happen you've got to have light movers, vented hoods, and really good air circulation in the room.
