GoGro 15L Pot System – Self Watering Pots for Tomatoes

Automatic watering for 15 litre pots, with no pump and no power

The GoGro 15L Pot System is a gravity-fed self-watering system made in Britain by HydroGarden under its PLANT!T range. Each 15 litre round pot sits in a tray fitted with the patented GoGro valve, which lets feed in from a raised reservoir only when the tray needs it; capillary action then keeps the medium evenly moist. Choose one, two or four pots with a 45L round reservoir or a 60L flexible tank.

What's Included

• GoGro 15L modules – round pot, PLANT!T valve tray with GoGro valve and copper root control disc per pot
• Reservoir – 45L round reservoir with lid or 60L flexible tank, as chosen
• Supply line and connection fittings

Key Benefits

• No electricity – gravity and the valve do the work; no pump to fail, no timer to set.
• Leave it for weeks – every tray keeps topping up while the reservoir holds feed.
• Floods to about 3cm, drains to about 1cm – a small buffer of feed stays under the pot.
• Uses your own pots – the tray takes most standard 15L round pots.

Why Hand Watering Lets Container Plants Down

Uneven watering causes trouble: dry spells check growth and lead to split fruit and blossom end rot, while overwatering starves roots of oxygen. GoGro gives at least two small feeds a day, so nutrient uptake stays even through vegetative growth, flowering and fruiting – ideal for tomatoes, peppers, chillies and cucumbers.

How to Use

• Stand the reservoir above the supply line.
• Lay the root control disc in the base under 1–1.5L of clay pebbles per module, then add your medium.
• Transplant established plants, not seeds.
• Allow 5–10L of reservoir per module; a medium plant takes 1.5–2L a day indoors.
• Give each pot a quarter turn every fortnight to keep roots out of the tray.
