tent nuggets
My flower tent is 4x5x4 600w cool tube. I have a 4" button fan to cool the light and heat the tent. My tent is in an unheated garage and it was 6F this morning.
750W little fan heater keeps the temp at 75F during lights out. This spring/summer some new engineering will be required to deal with heat removal.
I scored a badass blower at the thrift store for 5$
Here is a sativa with a runt and the cloner in my 2.5x2.5x4' veg tent. I'm using packing blankets over the tent to keep in the heat from the lights. I have a 175W MH and a 150w cfl
