Bird that's an interesting concept - I'm going to measure the difference in air pressure from compressing a chamber below my air floor and from drawing it out from above as I do now. Intuitively I'd think that higher air pressure would feed the plant more CO2, but the most potent bud is grown in mountains so maybe low air pressure aids as well as high UV light. Wicked cool idea!! This has to be researched by a crew of top men.
Top Men.
I'll post the research in my Grow Lab thread Bird. Kudos, great idea.
