In ‘4-Season’ specification, our Sprout range becomes a vertical farm, allowing you to grow all year round whatever the weather. Whereas ‘Solar’ gives you a self-vented enclosure with automated watering and off-grid capability. Add an optional sensor to minimise water waste, or to simply alert you via email. (when connected to wifi)

Height 90cm

Width 125cm

Depth 50cm

The greenhouse has a sealed, insulated back panel, so you can put it anywhere. It comes supplied with brackets to secure it to a wall, fence or the ground.

The Sprout S6 can take 6 standard sized seed trays over two shelves and the base. (a second shelf is available to upgrade the GH, Solar and 3-season models).

Alternatively, use a large garden tray, grow tubs, or your pots or containers on the mesh shelves.

The Sprout has been developed on the windy, gale-ridden west coast of Wales – it’s a strong, reliable greenhouse that will last you many years. Fully designed and made here in the UK!!

The 4-Season model is also suitable for cool, dark north facing gardens, at any time of year.

The 3-Season and 4-Season models are mains powered, and will need an outdoor 240v socket within 5m of the greenhouse.

The Solar model comes with a solar panel on 3m of wire. The panel will need to be mounted in good sun

Which Model For Me?

Greenhouse Only

A premium mini greenhouse, built to last. Strong aluminium frame and safe, protective twinwall polycarbonate panels.


An advanced automatic greenhouse to keep your plants watered and cool in the summer, and protected from the weather in winter.

Three Season

Grow longer into the autumn, and start earlier in the spring with built in heating. Requires an outdoor mains power outlet*

Four Season

The ultimate year-round growing system for small gardens, patios and yards. Additional lighting lets you grow more in the same space. Requires an outdoor mains power outlet*


Automatic opening, for Variable weather

The Sprout mini greenhouse will keep firmly shut on cool days, keeping valuable warmth inside. When it’s hot, the lid will open automatically to vent heat and prevent your plants overheating.

No electricty needed – just the magic of melting wax and springs. You can adjust the temperature at which the greenhouse starts to open, from around 18C to 30C.

The Solar, 3-Season and 4-Season mini greenhouses all feature the Harvst smart control system with self watering.

A submersible water pump and a range of drippers and sprayers are included, all you need is a water tank or water butt nearby. If you want to use a garden hose connected permanently to the greenhouse, you can do that instead.

Watering times are set on the Harvst app, from twice a day to once a week, for a duration of one second upwards.

You can choose to water more on hot days, and water less on cool days, to save water when it’s not needed, prevent your plants getting water logged, and also make sure your plants don’t dry out when they are likely to be drinking more.


Extend the season with greenhouse heating

The 3-season and 4-season models are heated with a low-voltage, waterproof heater cables. This is woven through the mesh shelves to provide a warm layer underneath your growing containers, keeping the soil at the right temperature for germination and growing on.

Choose the temperature using the app.

Unlike other mini greenhouses which can quickly overheat if left unattended, the Sprout will quickly vent excess heat via the automatic opening roof if the sun comes out on an otherwise cold day.

With heater on full, the mini greenhouse can maintain a soil temperature at least 10C above ambient, (without wind chill).


Year round growing with LED lights

The 4-season greenhouse comes with four waterproof LED grow lights, which are fitted under two shelves. These let you grow all through the winter, or can be used at any time of year to boost the light in a north facing garden. The lights are bright, so if you live in an urban area you’ll probably want to keep your lights on only during the day; perhaps from 7am to 8pm.

The lights are waterproof and can withstand the wet conditions in the greenhouse. They give off a fair bit of warmth, further helping the growing conditions in the greenhouse during winter.

Lights can also be added to the 3-season model later.

Control the light timings using the app, with two separate on times per day.
