Top 10 Best Cheap and Easy DIY Greenhouse Ideas
1. Lean-to Mini Greenhouses
If it’s old-fashioned and simplistic that you’re going for, these little greenhouses are easy to build. All you need is a few wooden plants, some nails, an old window or six, and a handful of old roof caps.
2. Mini Raised Bed with Greenhouse Topper
Another simple DIY greenhouse that’s made out of a light wooden frame and plastic sheets stapled on. You’ll also need a few hinges for this build.
3. Wood-Frame and Plastic All-Season Greenhouses
This cheap and easy DIY greenhouse is pretty much the same as the second item on our list. The only difference is that it can sit directly on the ground(rather than being mounted on a raised bed).
4. Garden Organizer, Grow Box, A-Frame Greenhouse Topper Combo
More of a seed starter/hothouse/mini-greenhouse, this cute little unit looks easy enough to whip together. It also appears lightweight and mobile.
5. Simple Grow Boxes With Hinged Windows
Perfect for growing lettuce through the winter’s coldest months, as well as starting seedlings in the spring and summer, these are some of the most common cheap and easy greenhouses to build.
6. DIY Pallet Grow Box With Hinged Windows
Another version of the last item on our list, this variation has windows that open in the center and fold outward, rather than windows with a single hinge or that need propped with stakes.
7. Brick Grow Box/Hothouse with Windows
This is definitely the greenhouse that the third little pig built. See the sturdy brick design? There’s no doubt about it; even the big bad wolf couldn’t blow this one down.
8. Pop-Out Greenhouse
Our verdict is still out on this item. We’re just not sure how well it would do in the wind and rain, let alone heavy snow. But, who knows! We’re surprised every day!
9. Homemade Pipe and Timber Greenhouse on Cinder Blocks
This greenhouse is what you’re likely to see pop up in our side yard sometime soon (we’re shooting for the spring of 2023). It’s sturdy, cost-effective, and can house hydroponics, raised beds, or a dirt floor.
10. Gabled Hybrid Greenhouse
The last unit on our list is another quick and easy greenhouse, but only if you buy the joists and siding pre-fab. If so, you can put this thing up in a matter of about an hour or two.
11. Square Meter Beds With Hinged Greenhouse Top
Whether you customize your wooden raised beds for square foot gardening or meter gardening, simply adding a light wooden frame with hinges on the top, with PVC pipes and plastic sheeting makes a great miniature green house.
