The 4 cobs hanging from wooden rod are sharing 220w. There’s another stand alone unit on my shelves aimed at the tomatoes right now that uses 160w. So between all the plants at that end of the closet they r getting about 380w. I’ve got lights on my 3 shelves that take about 300 watts also so maybe 700w in the whole room. Just have a standard bathroom vent fan in there that was added when i finished that room. Gonna wire it to a humidistat soon so it’s more automated. Got the part ordered already. Temps don’t get to high, bout 85f Max but humidity gets up to 80% also at times with Fan off.
