All of the windows are in!
Next the roof and door. Then the floor! Any suggestions on how to make the floor squirrel proof? I have 1/4 hardware cloth that I thought I could put up the walls about 7 inches before I put in pavers??

Had a few too many beers with the boys, and joked I eventually wanted to build a greenhouse on our off-grid property in Patagonia. So we grabbed some old logs, some pallets and a chainsaw....and got to work. First time greenhouser here! How'd I do? It will get full sun all day.

Still alive?!
Pretty excited my budget greenhouse is still cranking out tomatoes after two pretty frosty nights. Granted they’ve looked a lot better, but still alive!

Compost heater
Have been working on a compost heating system for my greenhouse. Built the compost pile with 400’ of black poly pipe and corrugated pipe coiled inside. Hooked up the pump and barrel and this video was my first test to see if it would actually heat the water. Got a 20+ degree temp rise. of the water going through the mulch pile. Now to hook up the heater.

Palma heater anyone?
I have a 12x16 prefab greenhouse in zone 5 that I’m currently insulating, but I need to get on ordering heaters for it.
I’m having power run to it next week and am planning on having a circuit breaker box installed in the greenhouse.
I’m thinking of putting 2 of the Palma greenhouses in, one on either end of the building. One is supposed to be good for 120 square feet so 2 of them with their own thermostats seems like they could keep up without working too hard.
It looks like other options would be to just go nuts and install a hanging 5k watt garage heater, something like this https://www.homedepot.com/p/Dyna-Glo-5000-Watt-Electric-Garage-Heater-EG5000DGP/307827993?MERCH=REC-_-pipsem-_-204760500-_-1-_-n/a-_-n/a-_-n/a-_-n/a-_-n/a
I’m installing 2” R10 foam board between the studs on the north and west sides and running it under the rafters on the north side. Not sure how much insulation I can get away with on the south side without losing too much sunlight.
I also have a 75 gallon stock tank with an aquarium heater set to 75F.
I’m planning to have frost blankets for the south side of the greenhouse for the crazy cold days.
The plan is to make this 4 season.
Any advice on particular heating units for this situation?
Thanks!

Glass and Poly greenhouses
Working on some nice and big greenhouse projects. I found this subreddit yesterday so I thought I will share some of the photo's here. We are working on some glass greenhouses and a big poly/plastic one, Including all the installation.

Finishing Pre-Fab Green House
Recently got a Pre Fab Green house. It has fiber glass ceiling with vents, wood walls and wood floor. I am currently deciding what kind of insulation to use for the walls. I am wanting to do try a few winter plants and then starters in the late winter (I live in Montana). I do want the inside to have a "finished" look.
Wondering if standard fiber glass insulation at r13 would be too much for the summer months... I am very new in my understanding for Green houses so any tips or recommendations welcome :)

My 8x6 polycarbonate greenhouse will be up today! What can I put in there?
More specifically, I’m in zone 6a and wondering roughly how many “zones” or how many degrees a well sealed hobby greenhouse can add on so I can think of which of my plants might like it in there.
I don’t need specific recs, but more like… how do you decide what stays indoors over the winter versus what can make it in the greenhouse? Thanks!

Can budgies bite through 2mm nylon string?
It's a single thread (not a braided string). For a toy If they do bite the lengths produced will be short enough to not produce a strangling hazard. What other alternative synthetic do you suggest?

Recs for buying a small polycarbonate greenhouse?
Hello! My wife really wants a polycarbonte greenhouse to grow arugula and fit a lemon/palm tree. And I love her so I want to get her one.
Ideally, this greenhouse could be on our 10ft tall back deck and be secure to not blow away.
I don't know want to commit to something permanent on our deck, so looking for anything thats not super permanent.
Apologies if this is vague, I don't know what I'm talking about.
Any guidance on what to buy/ where to start would be appreciated!

Tucson: will you adopt my tropical plants?
Hi! I’m looking for someone in the Tucson area with a tropical greenhouse who would be interested in adopting my plants:
- Majestic palm
- Dracaena marginata
- Parlor palm
- Crotons
- Snake plant
I love these plants and have tried to take great care of them, so I’ll only donate them to someone who has an actual tropical greenhouse. If you can, please send me a picture.
Note: Both the Majestic palm and Dracaena Marginata are from Florida. I brought them with me when I moved to AZ a couple of years ago, but they were much smaller then. I regret taking them out of FL because AZ’s dry air has been hard on them (hence the brown tips). The other 3 tropical plants were bought in AZ last January. I've been using an evaporative humidifier, but maintaining 50%+ humidity has been nearly impossible in my south-facing apartment. I know these plants would be much happier in a tropical greenhouse.
All plants are clean and bug-free!
If it's the right fit, I'm willing to drive outside of the Tucson area to bring the plants to you. I want these plants to thrive!

Looking for advice - Olea Europaea
Hello all! I have just built my first serious greenhouse with the intention of protecting my Bonsai collection for the winter. Most of the plants in here are native, or hardy enough to survive a winter in zone 6a. My favorite little trees however are not frost hardy.
Olea Europaea (Olive) shouldn’t really experience temps below 30°F. It also won’t do well indoors. I’m looking for advice on what to do with these little specimens.
Any help is greatly appreciated. I have a local Bonsai community that I will also be reaching out to. Thank you!

Would bronze polycarbonate with anti-reflective work for a solarium/greenhouse roof in a very moderate climate?
I have a chance to score some cheap roofing material, but it is bronze anti-reflective. I live near the coast. It never freezes and rarely gets below 50 or above 80. I need a place to get my seedlings started, grow some cactus and hang out.
I was lucky enough to get 70 old single-pane windows for €70 so the space is massive (22 ft dia) and the sides are all window. I was thinking of making a sandwich with two pieces of polycarbonate spaced about an inch apart. Will the temperature still get too in the summer to hang out?

Almost done
I apologize for my camera skills. Still under construction but almost done the greenhouse bar. Shares a wall with my manage that has a mini split for heating that’s why I have one fan blowing in and one out through the window. The other heat source is the wood stove. I have a loop of heated water that goes through a coil of copper that is on top, then through black iron that goes into holes I cut into the wood stove, it then goes into a 50 gallon barrel to store hot water. It then goes into the floor that I looped oxy barrier pex through so it heats the stone for more thermal mass, after that it goes into some buderas water panels that one of my customers asked me to remove (I own an hvac company). Finally it ends in to radiators behind the stove that also absorb some heat off of the back of the stove. I am able to get the water to 130 with burning my stove for 1 hour and so far it has gotten to 30 out where I live and it’s 68 when I check it in the am. I assume I will have to feed the stove more when it gets colder out

Hoop house
I'm trying to get things ready for old man winter. Nothing fancy here. I raise tropicals, and only use the gh for over wintering plants. For me, the cinder block shelves are the best fit. Inexpensive, easy to change configurations or move, and I can see and tend to plants better.
