FAQs

Are cheap PVC walk-in greenhouses worth it?
As a season-extender for hardening off and tomatoes, yes — expect two or three seasons from the cover and anchor it seriously; wind is what kills them. As a permanent greenhouse, a rigid glazed frame is the better spend.
What height counts as walk-in?
Look for at least 1.9m at the ridge to work comfortably; door height matters as much as ridge height. Dimensions are in every listing's specification — we surface them where stated.
