Having trouble keeping temps up, with fans on I'm around 17c/ 19c, that's only intake and outtake and not including the oscillating fan, I'd say I would be lower with that on,
when I seal up the tent and turn off fans and leave no vents or gaps open it's 25c/26.5, thinking of putting a 1000w heater that I hope I can dial in the right temps, it has 3 heat settings and a dial four lower and higher, any advise for using this heater,, shout away, on a brighter note, I'm on day 2 and all 7 seeds have broken soil, will remove the humidity cups tonight, just hope the heater can get me sweet temps inside the tent.
