I placed a humidifier, a heater with programmable thermostat and an oscillating fan in the room with them.
I was running a humidifier through veg but when extracting to outside it was pretty much a waste of 400W so I ended up using the temp controlled extractor fan in my grow room to move the hot air near the HPS to just vent into the larger attic space in a bid to keep the humidity up.
Might set my carbon filter up for next grow.....I don't need it when venting to outside but it might be handy to use as a scrubber when I'm not. It can get a bit stinky up here lol
It looks awesome! What strain is it? I want some! [emoji12]
Thanks buddy, that one was Dark Devil Auto from Sweet Seeds. I enjoyed that one so much I've none left.....seems to be a bit of a marmite strain but it's left me wanting to grow it again.
