3-Tier Cold-Frame Grow House

3-Tier Cold-Frame Grow House – a lightweight, tool-free mini greenhouse that protects seedlings, herbs and flowers from wind, rain and cold while extending your growing season by weeks. Perfect for patios, balconies, veggie patches and small farms across South Africa.

Why gardeners choose this grow house

• Season stretcher – traps solar warmth to give seeds and plugs a 3–7 °C temperature boost in winter.

• Storm shield – reinforced PE cover and roll-up zip door keep out hail, driving rain and gusty Cape winds.

• Space-smart – three ventilated wire shelves (10 kg each) double your propagation area without taking extra ground space.

• Five-minute assembly – click-fit, powder-coated steel frame snaps together with no tools.

How it works

Clear polyethylene lets sunlight in and captures heat, creating a gentle “greenhouse effect”. At night the cover slows heat loss, so tender seedlings keep growing while outside temps dip. Integrated zip vents give you humidity control: unzip half-way on mild days to prevent fungal diseases, zip down tight during cold snaps.
