Outside air vs inside air

[Seadaemon]

How much of difference would it make to the plants if I stopped using my outside air being drawn in via 4" fan, to drawing in inside air ? The outside air is approx 10 deg c. I am trying to get the temp up a little more inside my tent.

will depend partly on how big the grow is. most folk don't use active intake, just passive. the more important factor is exhausting spent air from inside the grow space to outdoor.

I have the exhaust fan off right now. It's just the seedlings in the pictures as far as the grow.

there are no pics. you should be safe for seedlings without exhaust. they don't throw much til they get into veg.

Air movement makes the stems a little stronger is probably the only advantage to being on, that or it another bro science thing but I would end up with less falling over in my grow boxes than ones I had under a lamp in the house, so who knows.

I have one oscilating fan going for the seedlings right now. You cant see it in the pictures though.

Looks good, fans are almost always good unless they are so much they cause dehydration to give my .02 on other comments
