holy shit, I turned the bedroom heater to 60 degrees (which usually results int 63 degrees), I turned on the fan on low, and turned on the LED grow light, and closed up the box, come back 20 min later and the led makes enough heat that the temp inside the grow box was 70 degrees, I am kinda shocked, so I am guessing that 70 is pretty good?,,, also the humidity is 50 percent ,, i am guessing thats good also?
