Hi folks! I usually hang out on the daylily forum but I have lurked here for a while as my husband and I set up our high tunnel. There's a lot to learn and I'm not mechanically-minded. I'm having a tough time figuring out the best place to buy the ventilation items and wondered if any of you would have ideas.
Our gothic high tunnel is 30' wide by 72' long, 6' side walls and 14' at the highest point. We have set up the steel frame and are working next on wood-framed end walls. Our rig has roll-up 16' openings on each end and crank-roll sides. Single 6 mil poly covering. We are in East Tennessee and the site is a bit protected, so wind and extreme temperatures aren't too much of a concern.
I figure I need to move about 16,000 CFM. One large and powerful exhaust fan or a couple smaller ones? Options for fan speed seem helpful. A couple shutters, maybe mechanized, maybe an extra, smaller gable shutter up high? Trying to save but don't want to waste money by making limiting choices on the front end. We paid so much freight getting the main GH shipped that I'm hoping to pick up accessories or find free shipping. Any guidance re vendors or general ideas would be very much appreciated.
