I have a few plants going under a 400W HPS in a tent. To cool it I have a vent to outside sucking cold air into the tent with a small inline fan. It works very well to cool the tent, but I just realized it is making my plants root zone very cold as they are in fabric pots and the cold air can pass right through. (Also I have the vent/ fan blowing underneath the canopies around the level of the pots). I have one plant in particular that I am worried about where the cold air is blowing directly on it. The buds - at canopy level - are at a perfect temperature with the lights on and this vent fan going. But when I feel the sides of the smart pot's they are in it is very cold right now. Idk the exact root temperature but I would guess as low as 50 farenheit or so. I think that's 10 celcius? Is this too cold for the root zone? Again the buds are at the perfect temperature, if not too hot (a few are fairly close to the light)
I'm thinking I might move this vent fan away and point it up or something so it's not blowing on all the fabric pots at the plants root zone. Then again, I want the airflow going underneath the canopy, and there's not exactly room for another fan atm lol... this thing is packed. So should I move it? Is this too cold for all the roots? The plants don't seem to have anything wrong, but it's getting colder out and I worry this fan could be making the roots too cold.
