Why I Chose today to open start using my greenhouse
Comments (15)Ohmygosh! I NEVER thought about the effect of sunlight on the placement of the intake vents/exhaust fan thermostat! My new GH is finished, at least to the point of being sealed, except for the frames we will add around the intake vents and exhaust fan and have rather abandonded it for the present, as we hustle to get our fall yard and field work done while the Sun shines, which it hasn't for much of the past month. But we do have electricity into the GH, so even when it turns really cold, we can still work inside of it and one of the questions has been the placement of the thermostats. Now I've been warned about the one for the vents/fan, I'll be sure to mount it in a shaded location, but what about the thermostat for the heater? My best sense tells me it should be mounted by the north facing door at the opposite end of the GH from the heater, because even with the intake vents and exhaust fan closed for the winter, the roof vents will still release excess heat. Yes? No?...See MoreTo diffuse or not to diffuse...
Comments (1)I built a custom greenhouse with polycarbonate, and haven't regretted it once. I love my greenhouse. I used corrugated polycarbonate, and believe plenty of light comes through. No matter whether you use 4mm twin wall or 8 mm twin wall or solid corrugated, you're still going to have heat loss. It's the nature of a greenhouse to lose heat, and if you want the inside to be at a certain temperature, you will need to consider a source of heat....See MoreGreenhouse question: to diffuse or not to diffuse?
Comments (9)Well, I am not on the East Coast, but in the Midwest, heart of Illinois and I use a Rion, have had it for a few years now & so far, so good as far as lighting. Yes any greenhouse will cost to heat, but least yours will be rather small compared to many.

Comments (7)Russ, Not sure who you are asking but I am in the Atlanta area. I don't have a greenhouse since I moved - just use my basement for winter care - run 86 or a few more shop lights and could use a lot more for optimum growth. My old greenhouse did have its issues as you mentioned - had roof vents but only two out of four worked. In summer I moved everything outdoors except cactus and succulents as they basked in the heat and drier conditions. The greenhouses I showed above are commercial grade and I guess they have the roof painted with something to lessen the UV rays or maybe some kind of shade cloth? Never gave it much thought since it is bright and very HUMID! They grew a lot of plants in hanging baskets to grow more on the benches below. One of the prop rooms showing fan at the end. The only time my wife accompanied me to a begonia buying trip for our local branch's annual sale. The mother plants grow to enormous sizes due to the bright light of Orlando. A mother plant of Judy Cook that I bought filled half my back seat in my truck. A plant for sale more plants for sale - biggest size they grow - 8 inches. A row of commercial greenhouses before we go into the sauna......See Moretapla (mid-Michigan, USDA z5b-6a)
