I built this greenhouse for my husband a few years ago and it's been amazing but with time, these windows have proven to be... difficult. The wavy plastic is cheap and easy to replace but I have no idea how to clamp them down to make it "air tight". The two pieces of wood on either side need several screws to force the plastic into a window shape and the wavy wood at the bottom breaks very easily due to the plastic fighting the frame.

Any advice would be much appreciated! Even if it's "Totally redesign those windows, here's an easier way"

20x13 hoop house. 1 1/2" schedule 40pvc and my favorite greenhouse covering. Between the shade cloth and the misters I can keep it on avg 10 degrees cooler than the in the sun temp. Blood oranges and key lime are fruiting. Several other fruit trees. Cannabis, sweet taters, weigelia, crepe myrtle and a banana that should have been uppotted a while ago

These were the first bouquets I arranged in my greenhouse last night. Had so much fun!

I’ve been slowly building this small tropical greenhouse in El Salvador around some of the existing trees and landscape.
It’s designed with lots of ventilation rather than being fully enclosed, using metal mesh, breeze blocks and a clear roof with shade cloth underneath. I’ve finally started moving some plants and worktables inside, although there’s still plenty left to finish.
Would love to hear what you think—or anything you’d improve before I fill it with even more plants.

Built this greenhouse during the summer vacation. We live in Iceland.

I recently finished my greenhouse build and thought I would share it here. The main goal from the beginning was to build something that could be a year-round, high-output food production system.

I put the first plants in on May 3, so I have had a few months now to see how everything actually works. Overall, I am really happy with it. There are definitely still some things I am figuring out. I have been battling ants, and my Venturi injector has been giving me some trouble, but for the most part everything is working the way I had hoped.

I thought I would post some pictures and specs and see where the discussion goes. I put a lot of thought into the different parts of the greenhouse and why I chose what I did. Some of those decisions worked really well, and there are already a few things I might do differently.

If you have questions about any of it, ask away. I'm happy to get into the weeds about why I made a particular choice.

The greenhouse

• Riga XL6 from Exaco
• 14 ft wide × 19 ft long × 12 ft tall
• Greenhouse sits on a 20-inch concrete stem wall
• 50-amp subpanel with two 20-amp circuits
• 7 electrical receptacles
• ¾" PVC water line
• Two Tornado 18" outdoor wall-mount fans for air circulation
• About 6" of drain pebble for the floor
• 4 Vego raised beds in different configurations

Lighting

• 2 × Medic Grow Fold 650W LEDs
• 1 × Medic Grow Mini Sun-2 500W LED
• TrolMaster HCS-1 controller
• TrolMaster lighting controller
• TrolMaster PAR Hydro MBS PAR sensor

I didn't want the grow lights to just come on at a certain time and run regardless of what was happening outside. The PAR sensor measures the sunlight coming into the greenhouse and feeds that information to the controller. That gives me the ability to use the LEDs as supplemental light when the plants actually need it, which should become especially useful during our Oregon winters.

Irrigation

• Rain Bird ESP-ME3 4-station controller
• Rain Bird 100DVF 4-valve manifold with flow control
• Venturi injector
• Cleanout valves on the input and after each irrigation valve
• Hose bib
• Vego irrigation kits feeding the raised beds

I wanted each bed to be its own irrigation zone so I could water differently depending on what was growing in it. I also wanted a way to run compost extract through the irrigation system, which is why I added the Venturi.

The Venturi is actually one of the things I'm still working on. I can get it to draw, but I'm having trouble getting enough irrigation flow at the same time. So that part is still very much a work in progress.

I'll attach pictures showing the greenhouse, the build, and some of these systems.

If anyone wants more details about something you see or wants to know why I did something a certain way, just ask. And if you see something you would have done differently, I'm interested in hearing that too.

Currently building a 16x16 greenhouse. It has a 2' sand battery underneath with both 4' air circulation lines and future glycol lines(might try something with a solar heat collector panel on the inside of the north wall)

We live in Central Alberta. The north wall(black metal) will be insulated.

Just working on installing the polycarbonate sheets now.

I’d like to remove that pos over hang from my shed and replace it with a greenhouse. The shed is 16x16, I keep fish in there so the tropical theme fits lol.* *I’m thinking either 14’ wide and 12’ out or 16’ wide and 12’ out

I’m in south Louisiana, zone 9b. Would I be better suited with a low pitch flat roof or gable roof matched to the main shed roof.

Also, corrugated plastic panels or the twinwall polycarbonate sheets?

It was 90% done last summer. This year the rock garden, rain barrel and exterior stain.

Hey all! Thanks in advance for any thoughts!

I need a heat source for a 170sq/ft green house.
Zone 8b
Average height 9ft
North,east walls solid and insulated.
South, west walls and south half of roof 8mm twin wall.
I’ve got 2 20amp circuits.

Was thinking a mini split? Pretty inexpensive these days.
