The 4' Midi Growhouse is a freestanding aluminium greenhouse designed to fit neatly anywhere in the garden—on a patio or gravel—with a compact footprint and a practical interior that helps you grow, protect, and harvest with confidence.
Why this growhouse stands out
-
Durable, long-lasting build — aluminium frame with a 25 year guarantee and stainless steel fixings for lifelong performance.
-
Clear, energising light — 3mm toughened safety glass delivers excellent light transmission and superior heat retention compared with plastic, without milky wear over time.
-
Wind and snow resilience — glass panels won’t flex under load and stay clear in all seasons.
-
Flexible ventilation — infinitely variable access through sliding doors plus roof panels that slide open for superb summer airflow.
-
Efficient internal layout — two deep, adjustable seed tray shelves that can be raised, removed or laid flat as seasons change.
-
Minimal shading — slim aluminium bars maximize light for plants below.
-
No special base required — simply freestand on a patio or gravel.
