Negative pressure need advice

Hello all!

I am working with a agroMax 8\8 tent and have a slight bit of negative pressure. When the light is off I must seal all vents to ensure complete darkness. I have a 4 inch inline fan for outdoor air intake and a 6 inch inline exhaust fan . My question is, will slight negative pressure hurt my ladies or is it okay to have a little while in darkness?

Re: Negative pressure need advice.

Negative pressure ensures all exhaust flows out through the exhaust fan and filter, if you have one. It shouldn't have any negaative effects, as most growers run this type of ventilation with no problems.

If you run a positive pressure ventilation system, it can allow the smell to leak out of the cabinet, where air would otherwise be drawn in with a negative pressure system.
