How to Choose the Right Backyard Greenhouse Kit: A Gardener's Guide

From DIY Hoops to a Real Greenhouse

My first attempt used PVC hoops and plastic sheeting—better than nothing, but tedious to vent and water, and the plastic tore after one season. Upgrading to a 6×8 polycarbonate kit changed everything: easy assembly, three extra months of growing, and thriving plants. But I quickly outgrew it. Here's what I wish I'd considered first.

Key Questions Before Buying

1. Budget: Kits range from hundreds to thousands. Good small ones exist, but size correlates with cost.
2. Size needs: Will you grow winter greens? Start hundreds of seedlings? House tropical plants in summer? List your uses, then size accordingly.
3. Available space: Small fenced yard? Consider a portable greenhouse with Velcro access flaps for hoses/cords. Some collapse for winter storage.

Materials and Features

• Frames: Plastic, aluminum, galvanized steel, cedar, or redwood. Plastic kits lose least heat and are most affordable.
• Glazing: Polyethylene, polycarbonate, or fiberglass—unbreakable, great insulation.
• Styles: Classic gable, Victorian (rustic wood or gothic vaulted), lean-to.
• Extras: Shelving, flooring, anchor systems often sold separately. A level foundation (wood, concrete, patio stones) ensures drainage and wind resistance.

Build or Buy?

Handy? Hundreds of free plans exist. I'd rather garden than hammer, so a kit was right for me. Either way, a greenhouse elevates your gardening to a new level—plan thoughtfully, and enjoy the harvest.
