Classic Growhouse 1.5m length
The Classic Growhouse 1.5m length is a premium, extra-deep freestanding growhouse, perfect for compact spaces as a versatile cold frame or mini greenhouse. At 1.5m (5ft) long and 1.81m (6ft) tall, it offers generous headroom and outstanding flexibility while staying neat on a patio or small garden.
Built to last, designed to grow
-
Glazing: 4mm toughened safety glass delivers superb light transmission, holds early-season warmth better than plastic, and won’t turn milky over time. It stays rigid in high winds and under snow loads.
-
Frame: durable aluminium structure with stainless-steel fixings and a 25-year framework guarantee. Ground fixings are included for bolting to a firm base such as a patio or concrete.
-
Finish options: choose natural aluminium, or painted colours Antique Ivory, Smokey Grey or Cotswold Green to complement your garden style.
Optimised space & smart ventilation
-
Access both sides: smooth sliding doors at the front and back create a very wide opening for easy tending and harvesting.
-
Fine-tuned airflow: doors and sliding roof panels give infinitely variable ventilation - from a narrow crack in spring to wide-open on hot summer days, helping to keep plants healthy and reduce disease.
-
Extra-deep interior: the 0.79m (2ft 8in) depth maximises usable space, so you can keep shelves installed while growing taller crops like tomatoes, peppers or dahlias.
Staging & watering that work with you
-
Eight adjustable deep seed-tray shelves: set the height you need, drop flat, or remove completely as plants size up.
-
Toughened-glass centre staging (rated to 25kg per sheet): lets light reach lower levels; remove any of the three sheets in summer for full-height growth.
-
Two-tier mist watering: fine spray nozzles on both levels, gentle enough for seedlings, connect to a standard garden hose for quick, even coverage.
Why gardeners love it
-
Ideal for seed starting, hardening off young plants, and year-round salad and herb production.
-
A brilliant upgrade from a basic cold frame, with the practicality of a mini greenhouse but without dominating the garden.
-
Supplied for self-assembly with clear, full-colour instructions; optional accessories include automatic louvre vent, shade and shelf covers.
