FAn and vent placement

[Zappa]

Hey everyone. I am moving ahead on a project and wanted to know if the fan should be blowing down onto the plants and the vent at the bottom ... LMK which is best... Z

You need a fan blowing out of your box near the top and a vent at the bottom. The top fan sucks out the heat. Heat rises so the intake vent is near the bottom to pick up the coolest air. You should also have a small fan blowing on the plants.

thats a good idea for stems stealth if you dont do that the stem will grow weak
