Y ah I grow in an old sauna so its really well insulated but the concrete floors are cold all winter long.

I can say one thing though, make sure if you get a heater that its a goooood one! I had a thermostat break on a friends heater, his room got over 105 before he woke up and noticed it was on the fritz.


Since my room is 74 during the lights on, im going for 64-66 with lights out, heater barely pops on , then runs maybe 2 minutes before a 10 minute rest.
