I've had to move flowering plants to the garage. Purchased a 4x4x7 grow tent and 400W HPS light. Have a mall fan blowing fresh air in from one of the vent hoods near the floor.
Issues: Temps in garage are in 50 - 60 range (until summer).
Using a small space heater - can only keeps temps in the high 60's (day)
Run light at night -
Plant is not liking this - some heat stress.
Questions:
1. Suggestions for other heat sources? Would a small oil-heater work better? I'm guessing all the hot air is bad for the plant. Or an electric blanket in the bottom of the tent? Or electric floor heat mat?
2. When summer comes (soon) I'm guessing daytime temps (no light) can go about 80 (or higher). Will I need to plan to exhaust the air? Possibly just exhaust the heat from the light? I was going to get a second 400W light (to accommodate 4-6 plants) but now thinking an investment in decent reflector + exhaust system for light will keep it cool enough (lights 9pm to 9 am) and allow the light closer to the plants. I still plan to run a fan to bring cool air into the tent.
Or, can I simply draw air from the tent via the light and its exhaust? (i.e. not a "closed' system) Or does the light exhaust have to be a "closed" system (in from one vent out via the other).
