Pushing
Pushing/ pulling is a preference thing I suppose, but I get where your coming from. As long as theres a sealed path from fan to exhaust i don't think it would make that big of a difference either way. I.m.o.I'm going to try this out today. I'll try to get up there and look for a vent but it's not easy to access being directly above my plants.
Why do you push? I believe pulling is more efficient with the hoods I have. Pulling makes sure the air is smoothly traveling into the next hole/flange whatever they r called. If your pushing air towards one side of the hood there's no way to garuntee a smooth path UNLESS you have one of those tubes surrounding your bulbs, but I use the styles that have a swing down glass panel.
