Mars hydro TS1000

I have everyone elevated off the ground and they are fairly close to a vent where both heat and cold come out.

That ts1000 puts out quite a bit of heat on its own ive noticed.

Keeping the humidity up is the biggest challenge winter growing has to offer.

Thats why I use a radiator. Not as bad as forced air.

I too am in CO. I am transitioning from swamp cooler to heater and my humidity drops by 40% easy. I run my lights at night to help with heat also. I just bought an evaporative humidifier for inside the tent to fight the heater drying out the house.

That is really all we can do here in the mile high.

All of the above. Try to keep the temps where the plants are between 70-80 degrees F and humidity above 50%RH if at all possible. The smaller and younger they are, the more sensitive they will be. I think I lost a couple of cuttings/clones I kept alive for 8 weeks yesterday because the temps and RH dropped suddenly 2 nights ago. It hit 63F and 40RH inside the tent. The larger girls did not even notice it, but the small ones in solo cups suffered greatly. Entirely my fault, I had the heater out and sitting right next to the tent. I just forgot to turn it on.
