Ensure it is heavy duty to avoid overheating, and only use enough length to do the job( I know, that's what she said).get a small radiator heater and run an extension cord from a different circut .
Just wanted to come back and let you know your advice helped a ton! Laid blankets down and my inkbird is on its way! Nice and warm in there now! thankyou!That cold concrete floor is a formidable adversary. Especially since your grow room would only heat a tiny portion of it. If they're not already, I'd elevate your plants a couple feet above it. Then I'd put a layer of insulation between that cold floor and the grow area. Cover the floor with blankets/sleeping bags/pillows....whatever you've got. Get your inlet air from a warmer part of the house. Get an Inkbird controller to automate whatever auxiliary heater you decide upon. Good Luck!
Yeah i'm from Niagara, Ontario. Not all that far from Michigan. I did the exact same thing with my ducting now using insulated ducting.I think the thing that made the biggest difference was a simple blanket on the cold floor. Didn't realize just how cold it was until a poster mentioned it. I always wear shoes inside. I was focused on the roof. A blanket on the floor made a huuuuge difference. Got a rad heater and inkbird now and I'm ranging from 74-80Im in the corner of the basement and my room hit 48 one night. I ran pvc from my heat ducts into the room. My room now only drops to about 57 on the coldest nights here in Michigan when lights off.View attachment 4495207View attachment 4495208
Awesome thanks for the advice!Go to a local hardware store and pick up insulClad material..or levelboard. It is insulation panels used when renovating and improving insulation on the outside sheathing of homes which are being resided. It comes in varying thicknesses, usually 4x4ft panels, or accordion style.
Works better than a blanket.
Good luck.
