Zone four folks! I would love to see what your greenhouses look like, please post pictures and things you love about your greenhouses in this zone! Looking for inspiration as I undertake expanding my hobby gardening. TIA!

I just constructed my first greenhouse - the famous Costco 7x8 yardistry option. Love it so … and just saw they’ve revamped it to add a window, make it taller, and the door is on the long side. Argh. Tell me I don’t need two!!! 🤣🤣🤣

Looking for an affordable place to get double walled, corrugated, polycarbonate panels. A few of my panels were installed with the uv protected side in and are yellowing pretty bad after a year and a half. Panels from the manufacturer seem overpriced, and on top of that shipping is around $250, which means replacing about 8 panels would be in the $600-700 range.

All of the upper full panels are wrong, as well as the two window panels. The ones under the windows are correct, as you can tell by the lack of yellowing. Was my fault because I started putting the greenhouse together, wife went into labor and had to have builders come and finish, and I had already taken off the protective sticker on the panels indicating the correct side to face out.

Live in Massachusetts and looking for recommendations for a heater for a 10 x 12 Harbor Freight greenhouse. Don’t really need year round (though that would be nice) but enough to extend the season a few months.

Made this for my better half last summer.

One of my very favorite builds that my installation company has done. We handled everything, including the foundation and beautiful rock work. Located in hard hit Hendersonville, NC, an area that was hard hit by hurricane Helene. It and all of our other projects in the area survived, unscathed.

I just love it.

Hey guys, I have an oil furnace that a couple times over the past couple years has broken down for one reason or another in the middle of the night. I have a furnished guy who always comes and fixes it the next day, and it's usually stupid small things. However, my greenhouse is full of valuable stuff. Are there propane heaters or something like that that I can have set up and ready to go if a temperature drops below a certain temperature? This way if the main furnace fails, which it rarely does but occasionally does, the heater will keep the greenhouse at least a little bit warmer so the plants aren't damaged before I can get the furnace repaired? I see a lot of propane heaters at Lowe's and everything, but I think you have to manually start at those too. The problem is when my furnace kicks off in the middle of the night sometimes I'm asleep and I don't see it until I wake up. Thank you

Design im basing my build off of is linked here: https://www.diyinprogress.com/blog/building-a-greenhouse-base-and-framing-it-outnbsp

My question is about anchoring...I want this to be a somewhat permanent structure. Should I pour footings with a sonotube or is that overkill? Will deck blocks work?

I've been collecting old single-panel windows to build the walls of a greenhouse with and the plan is to stick frame a lean-to with the walls made of glass and the roof made of polycarbonate sheets. Since the windows are single-pane, though, I'd like to insulate the walls by adding an interior layer of polycarbonate to let as much light in as possible, but create some dead air between the studs for more insulation. Any thoughts or suggestions?

Note: I'm in zone 8a and will mostly use the greenhouse for early germination (so I don't keep getting soil all over the laundry room lol)

I have a nursery and I am considering installing wiggle wire on our greenhouses for our poly. Anyone have experience with these? Are there more cost effective/less labor intensive options? I also want to be able to roll up the poly on the side walls instead of removing it every year. Any suggestions for this? Is this something I could do for the hoops as well? Any advice is greatly appreciated. It's becoming clear that I'm not going to be able to continue removing it and reinstalling it every year due to my own back issues and the cost of materials and labor to have someone else do it.

Has anyone seen any smaller scale shade cloth setups that are automated - picturing something that just basically rolls along a steel cable in one direction on command then the other to stow.(one for each line)

A lot of the more commercials use tracks or awning style systems but, was picturing something more DIY.

I am in charge of two new greenhouses at the farm I volunteer on and I am looking to install humidity sensor-controlled misters.

Does anybody know of any systems available for sale or how to build one?

I was able to find this humidity controller outlet:

And this mister system:

But I would need a controller to turn the flow of water on and off from the faucet/garden hose. A pump solution isn’t necessary as the water already has pressure so it would be some kind of AC powered solenoid valve that opens when the humidity sensor activates.

I am thinking this might work:
