Mini Greenhouses

A mini greenhouse is a freestanding 4-6 shelf unit, usually 1.5-1.8m tall and 70-100cm wide, with a transparent zip-up cover. The format suits balcony or small-patio gardeners who want a propagation space without committing to a full walk-in greenhouse. Aosom UK, Buy Sheds Direct and Cheaper-Online.co.uk between them cover £10-£418 across the range. The cover material decides how long the mini-greenhouse lasts: PE (polyethylene) covers last 1-2 seasons before UV cracks them; PVC covers last 3-4 seasons; reinforced fabric with mesh windows lasts 5+ years. Frame specification matters in a windy garden, cheap painted-steel frames bend in autumn storms; powder-coated steel or anodised aluminium holds up year-round. Anchor it. Mini greenhouses are lightweight enough for a March gust to flip empty; tie-down kits or rope-and-peg anchoring is essential. Most have removable shelving so you can fit larger plants by removing a shelf.
