Some help with air circulation?

ChronicVic said:

Hello,

I have a grow tent where the temperature is constantly 70 degrees. everyone tells me I need to exhaust the air and bring in fresh new air, but if i did that, the cold outside air would drop the temperature 25 degrees in the tent, killing the plants. Is it possible for them to grow without exchanging the air, if i just have a few oscillating fans in the tent?
Thank You

Plants need fresh air. You need circulation.

You don't need to bring in air from outdoors. Just from the room the tent sits in.

it doesnt have to be outside air, but you must exchange the air within the tent constantly, the plants need a constant supply of co2 for their thang!

Unless your tent is air tight, you're probably getting enough exchange imo. I would think of it the same way you could stay in the tent and not suffocate. Are you noticing any problems wit the ladies? If not, keep it up.. My first round or two I was worried about temps getting too low during lights off, having heaters on timers and shit.. Now i dont really care cause I know it's not getting that cold

I change my fans up. sometimes I turn on high sometimes I turned on low sometimes during the dark hours I cut the fanss off. the wind does not always blow when outdoors. When the plants are young I use a stronger fan speed to strengthen the stems
