Give plants just the water they need using a combination of soil moisture sensors (optional), temperature and a timer schedule.
Dual zone watering for different plant requirements; sprayers for bottom level and misters for the top level…. or set it up your own way.
The system saves water by pausing the timer schedule if the soil is already moist, and prevents your plants from getting waterlogged.
Soil moisture sensors are an optional extra.
Settings and system control is via a Smartphone connected to either the control box Wifi, or your home Wifi. With a home Wifi connection, you can also choose to receive alerts when the inside temperature is too high or low, when it’s watering, when the tank has run out, and more.
A wifi connection is not needed, but will give you extra benefits, including the ability to monitor and control your small automatic greenhouse from anywhere!
All Harvst mini greenhouses come with an automatic opening roof system included, to help prevent your plants from overheating. Unlike other small greenhouses, grow houses or cold frames, the Harvst automatic vent is a whole-roof system, to deal with the hottest of days.
No hidden extras here; automatic opening is standard equipment to protect your plants and help you grow more.
The Yard model has two shelves included; giving three tiers of growing space. They are strong aluminium, spaced so that 38cm x 24cm seed trays fit neatly.
We recommend standard, shallow seed trays for the top shelf where you can start your seedlings using the mister sprays. The middle shelf is good for deep seed trays; salads, herbs and so on. Up to five seed trays fit on each shelf.
The bottom level is designed to take any large growing container up to 600mm from front to back. Three 600×400 Euro crates will fit. Alternatively, put your Yard greenhouse on one of our raised beds and fill it with deep soil for root vegetables like beetroot or carrots.
Our small greenhouses are great for growing home grown greens and vegetables as well as flowers. Because they are warmer than the outside air, you can plant earlier in the season than you would normally, and keep harvesting later into the autumn.
We love salads, and with a well packed, well managed Yard greenhouse, you can expect an average of 4 bags of salad a week for much of the year. With our heated greenhouses, you can have fresh greens and salads all year round.
Other vegetables that work well include Radish, Spinach, Pak Choi, Carrots, Chard, Beetroot, Rocket, Herbs like Basil and Coriander – all looked after carefully for you by the smart automation.
An electronic control box monitors the conditions inside your greenhouse throughout the day and night. Temperature and soil moisture readings are taken, and when the system decides your plants need water, a low-voltage water pump is turned on. Water is sent to one of the two zones using an electric water valve built in to the irrigation system. The water pump can be in a small tank placed in or near your greenhouse, or you can use an existing water butt.
If you have a mains powered, heated greenhouse, then you can plug low-voltage heated seed trays or heater cable into the control unit. Heated seed trays are great for germinating and propagating plants that need warmer temperatures – such as peppers. The heater cable keeps the ambient temperature of the small greenhouse up, helping general growth, and preventing attacks frost.
