Smart self watering. Better for your plants. Easier for you.

Harvst Solar, 3-Season and 4-Season greenhouses are fitted with a smart control system which uses a combination of timers and sensor readings to turn on your watering.

App controlled.

All settings are managed via a web app which is compatible with iPhone and Android, and also runs on a laptop, tablet or computer.

Weather responsive.

More water when it’s hot, less when it’s not. Set up your self-watering system to give an extra boost of water if the temperature has been over a set level for more than a few hours.

Manage and monitor from anywhere.

If your mini greenhouse is within range of a WiFi network, you can connect the control system to the internet to view data and update settings from anywhere.

Run from a tap, or from a tank with a pump

Simple tap timer.

If you can run a hose pipe to your mini-greenhouse, then you can connect it to your greenhouse with a standard “tap timer”, available from any gardening outlet.

Not required with the Solar, 3-Season or 4-Season ranges which manage irrigation using a smart control system.

Tap with electric valves

Tap with internal electric water valves.

For smart sensor based watering, add a Harvst electric water valve to the Solar, 3-Season or 4-Season greenhouse models. This acts as an automatic tap, turning on the water only when it’s needed.

The Harvst valve is dual-zone, so you can water two separate areas within the greenhouse (or even outside).

Greenhouse water tank

Pump and tank / water butt.

No tap? No problem. Harvst Solar, 3-Season and 4-Season greenhouses come supplied with a small pump that provides the irrigation needed. Mount this in a tank or water butt of your choice, within 2m of the greenhouse.

Our pumped system is also compatible with the dual-zone water valves.

Misters, sprayers, drippers ... or hydroponics.

Harvst automatic greenhouses come with a range of irrigation parts so you can decide what works best for your setup. We provide pipes, connectors, misters and drippers, with some recommended setup options.

Sprayers are great to keep shallow soil (or a microgreens mat) moist while seedlings germinate. Drippers are great for delivering water precisely to the roots of larger plants, or for filling a tub or watering tray for bottom watering.

The included taps let you shut of or control water flow to different parts of the greenhouse as you move plants around, or as their water needs change.

Harvst mini greenhouses are also a great enclosure for a hydroponics setup. The control unit can run separate watering and misting pumps, monitor temperature & humidity, and keep you updated with conditions inside the system via email and SMS notifications.

Misters / sprayers

For a simple, versatile watering system to get most of the greenhouse interior wet.

Drippers for soil watering

Adjustable, for direct water. Can be shut off completely if needed.

Taps for flexibility

Create separate loops within the greenhouse and control each loop separately.

Add soil moisture sensors for precision watering.

Soil moisture sensor

Only water if it’s dry …

The Harvst self watering system is available with dual-purpose soil moisture and temperature sensors, which gives your plants extra protection. The watering can be triggered when the soil is too dry.

and save water if it’s already damp.

Using the Harvst soil moisture sensors, you can set your system up to prevent watering when the soil is already damp, saving you water and preventing your plants from getting waterlogged.

Two separate irrigation zones for versatility.

The Harvst control unit can water two different zones separately, so you can give each crop the right amount of water depending on its stage of growth, or its water preference.

Our automatic greenhouses come a standard with one watering zone. Add the Harvst water valve kit to your greenhouse for this capability.

Each zone can be controlled using sensor data (soil moisture, and temperature) and/or two timed schedules per day. From one second upwards.

The water valves can be used with the greenhouse pumped water system, or connected directly to a garden hose to act as an electronic tap.
