Hi my friends, what could I use for ventilating my growbox without a fan? I just have to grow 1 plant
Well, depending on the size of your grow box it could kinda naturally happen through thermal exchanging. But you can never rely on that. You'll need an exchange of fresh air for the plant. The heat build up is going to cause issues as well.

Maybe, just maybe, if you have strategically placed passthroughs. Fresh air intake on the bottom and vents on top for exhaust. Using a slight venturi effect would draw in fresh air when your lights on. But lights off and it'll stagnate. In that case, get some small box fans, 5v computer fans.

I dont think its going to go well. But its worth a shot right? Take pictures of your setup as is. Im sure theres going to be plenty of input from others.

Take the ceiling off and let the laws of physics take over..

On a serious note, how big is this box and do you mean without a fan of any sort or without a proper extraction fan ?
What wattage light is in there?

Judging by a photo on another post it's a grow tent, probably vivosun.

I ran a small fan but no exhaust in my micro grow box I did for fun. Just opening the door couple times a day is enough exchange. I forget the exact dimensions but something like 20x24in and 4ft tall.
