Have some decent starts this year and heading into june looking much better than last year. I know my plants are gonna get tall and wide. Everything is in a 14 foot(at peak sloping down to 8 feet on the sidewalls) greenhouse.
I don't usually top or do anything other than LST, but would like to get the most out of my plants and space. Things get pretty hot at the peak without a roof vent, so I'm thinking keeping the canopy at least 12-18 " below the roof would be better.
I have spare controller lying around somewhere. Twin 30 inch twin intakes and outakes do decent job at venting(run all damn day) but a 3rd should have been installed at the peak to help.
