A Harvst greenhouse protects your plants for you.

Mini greenhouses are by nature a small, enclosed area that can quickly get hot and humid. Without a way to open the windows, doors or roof automatically, your plants will suffer.

All Harvst mini greenhouses are fitted with a wax based automatic window opener as standard. This will lift the whole lid when the temperature inside rises, quickly venting heat and keeping your greenhouse cool.

No power is needed. The system works with a combination of springs and melting wax for reliable, long life.

The opening temperature can be chosen – between 18 and 25 degrees – by screwing the piston in or out.
