A customer has a question and I hope we can get some opinions on it, thanks
“I live in upstate New York, Adirondacks. I set up my grow tent and hung a 270 watt LED but my tent isn’t warm enough. I’m germinating 4 seeds in case one doesn’t sprout. The temperature went down to 64 at night so I brought my girls inside to keep them warmer. I thought the LED would give off a lot of heat but it doesn’t, also has a fan. I planted seeds on 4/16, it was 80 degrees during the day. No sign of growth yet. Should I add another light? Just don’t want electrical expense of HPS light. You don’t think I should get another led? Are these heating methods specifically for grow tent? Need help or suggestions!”
I use a 24" x 48" heating mat to line the floor of my 2 x 4 tent and it helps keep my tent in my unheated basement about 72 degrees even in winter (near Boston). I considered adding a space heater but this was all I needed. although I keep my sprouts and seedlings in a propagation tray with domed lid and under a T5, I don’t introduce them to the LED or the tent they have outgrown the dome. I have the smaller mat that @kabongster linked under my propagation tray, and the larger size from the same maker on my tent floor.
Same set up for me only thru basement into back garage probably little colder. Right now I moved my 3 seedlings and 1big bud that never popped and 1 new big bud germinated on 4/23 back into grow tent. My temps are 78 w/56 humidity during day but 68 lowest night temp w/56 humidity. Should they be in the tent? I have 270 watt LED, heating mat and another LED arriving any day now. Also worried about big bud
