This is my greenhouse I built last summer from plans I found on an Alaskan homesteader’s website. I put 16” raised beds 36” wide on 3 walls. They are filled with commercially once used 70/30 coco from 100 gallon fabric pots. I filled the beds last October and sprayed heavily with a solution of hydrogen peroxide and water. I then covered them with plastic sheeting and let it sit until March 15. I removed the cover and amended the coco with Subcool’s super soil recipe for about 33 cubic feet, dosed it with Mycorrhiza, and covered with a tarp and let it compost till May 15. The myco did its job well. The coco fibers are nicely composting and it has become a nice light soil with a PH of 6.23. My plants are thriving and loving it. All I give them is water at 6.0 with Growers recharge compost tea and unsulphered blackstrap molasses. They get sprayed every Sunday with a mixture of IPM and Liquid Seaweed. These are pics of the build phase. The reason I built it is the 2 plants I put in the ground. The first cannabis plants I have grown. They did so well, I built the greenhouse around them!
Now that’s a greenhouse. You can grow some sativas in that SOB. I noted a couple vents on the front, right? R there fans? Also do u have a roof vent? Also i noticed you packed all the corrugated joints w/foam, very nice. Presumably you have a lengthy summer grow season, yeah? And you post:
I’m going to go out on a limb (pun/no pun, u judge) here and say this is the first time you ever grew cannabis? Well, boy howdy, you’re all over it, whether the first time or the 100th. Keep it goin’ bro. NICE!
Thanks all. Hold on cause that was last summer. It is robust. Here’s a few pics of where I ended up.
Yes, it’s a tank. We get severe storms and winds so I wanted it stout. Overkill? Perhaps but it can take a hit.
I grew Golden Tiger last summer. There’s a few pics of it and Sugar Cookies
The last pics are this year. Only 9 of what you see are in the ground. Hunting through the others and will run the winners indoors
The giant plant is Ricky’s Hashplant from Brothers Grimm. It’s a damned tank. It’s only been in the ground since the 17th
The setup is as follows. I have 2 intakes with temp activated apertures 2 exhaust fans on temp/humidity trigger, 2 8” Shaefer HAF fans hanging from roof on each end facing each other to create circular air flow, 1 16” vortex fan pointing up, and a Hessair swamp cooler on a humidity trigger. Using Trolmaster Beta series controllers. Not installed yet, but will be using a 11x11 grid of 3/4 tubing and pin holes. I will use a B-hyve timer and pump relay with a 26 gallon tank.
Beautiful cultivation project, the greenhouse is excellent, I really like organic cultivation, I also do organic outdoor cultivation.
But be careful of the night humidity in the greenhouse.
This looks like a solid build! I was looking at building a greenhouse soon but couldn’t figure out how to make it sturdy enough and not break the bank and yours looks like it fits both of those. How does it do in terms of temperature regulation? I was looking at using twin wall polycarbonate for the walls, but maybe temps aren’t as big of an issue for you down in OH as they are for me in ME.
Lol, Ya right… My little 12x12 gets over 100 easy at peak sun with all vents wide open in north central CT… Don’t think I could feed a swamp cooler enough juice here
Nice build, tho. I think I’d customize the roof panels to open and close with auto green house roof vents. Been using one on mine to open and close a.large central panel ridge vent on the leeward wind side, pulls like a vacuum.
Here’s a few pics of where I ended up.
