Start growing early, and harvest late. Get more out of your growing season, or even grow all year round. The Harvst grow houses will protect your greens from frost, open automatically to keep your plants form overheating on a hot day, and can even be heated during the colder periods of the year.
Windows open using a wax cylinder greenhouse window opener; simple, reliable and electricity-free.
The walls and roof are made from twinwall horticultural polycarbonate, acting like double glazing.
Even without the automated control system, you’ll get a lot more productivity from your garden with a Harvst self regulating cold frame / mini greenhouse.
