50a sub panel should cover me if I choose to add lighting in the future, will also be for service plugs for fans, controllers and exhaust system. Have gas nearby too in case I want to add a heater for frost protection.What is your plan for the floor? With 50a service indicated, perhaps you are planning ahead for a dehumidifier
I haven't actually tried to run a greenhouse in this climate, so I'm piecing together some of my experience with outdoor here, working in other people's greenhouses, and things I've read or heard. I'm thinking that the ventilation system will be effective at reducing heat build up during the summer, but come fall when it gets cold and wet out and the vents are closed, I might get a humidity build-up. It's possible that I could use heat to control that, but there are those in between days (or weeks) when its too warm to run heat but too damp to pull outside air through. I'm trying to account for all conditions, but I don't have this completely figured out yet.If you are trying to use your ventilation system to regulate temperature, a dehumidifier would not be useful. Exhaust system designed for 1 air exchange per minute.
Why the double roof plastic? Are you using true greenhouse plastic, or the standard "clear" 6mil from someplace like Home Depot? I ask because I've read that a single layer of plastic can reduce the light by 20% (IIRC). One summer I grew the entire summer under plastic, the next summer I grew in the open and only put the plastic up mid-September when the first fall rains started. I've also read an article that talks about how diffuse light can be better for plants, obviously greenhouses work, I'm just interested in how different materials function.You can kind of see what I have done. Each side can roll up plus if need be the top can roll also..Plus 2 fans... double 6mil. plastic for roof is a must.
Last year buds where huge! BUT! a lot friends lost bud to rot because of humidity. I was lucky, lost very little. Ventilation 100% better this time.
Very nice...moving right along.An extremely productive day, everyone moved into their 65s. Stump got ground down this weekend so was finally able to set all of the other posts. Digging level tomorrow and possibly setting 2x8 pressure treated base rail if I can get it in there before sunset. View attachment 3964347
looking great good luckAn extremely productive day, everyone moved into their 65s. Stump got ground down this weekend so was finally able to set all of the other posts.

Oops, forgot to procure pallets. They're on membrane roofing so they'll slide in. They are big, the tallest will have to go in the center where the roof will be 10'. Been a busy couple of days here, will post pics this weekend after I get some more framing complete.Nice, but how you gonna get them on pallets now? Maybe not needed, I don't know. I think you'll fill up your space like a jungle, you got some big girls going for this time of year. Keep them off your ceiling, that will foul them in flower, wherever they touch it. Days are getting shorter now so get that hammer swinging!
In retrospect stainless steel post sleeves could have been added, but were notYou are reducing the life-span of your wooden posts by setting them directly into concrete.
