Umbrella Greenhouse

Those transparent bubble umbrellas aren’t just a fashion statement; they also double as mini greenhouses. There’s no drilling, sawing, or DYing required (some companies even sell umbrellas specifically for gardening), and they’re great for urban gardeners who have limited space. Simply place the umbrellas directly on plants or circular planters.

Recycled Window Greenhouse

While DIYers’ plans vary, most build a wooden frame that they then fill with old windows rather than plastic sheeting. Below, Babbling in My Backyard provides detailed instructions on how to approach a recycled window build, and you’ll find similar tutorials across the internet.

CD Case Greenhouse

Before you donate your CD collection, you should know that you can make a miniature greenhouse with 40 or so jewel cases. As you can imagine, it’s going to be pretty small — only large enough for one or two plants — but it’s nearly free to build, assuming you’ve got old CDs lying around.

Greenhouse Kits

Gardeners who want to skip the whole DIY process can buy a cheap greenhouse kit from Harbor Freight, Amazon, or Costco, though it’s hard to say how sturdy these structures are. Still, if you need a greenhouse on the cheap and don’t have the time for a full-on build, it’s not a terrible idea.
