GoGro 25L Pot System – Self Watering System for Greenhouse

Hands-off watering for big 25 litre pots

The GoGro 25L Pot System brings HydroGarden's PLANT!T GoGro self-watering valve to larger containers. Each 25 litre round pot stands in a tray whose patented GoGro valve meters feed in from a raised reservoir, and capillary action draws it up through the medium. With no pump and no mains power, it sets up anywhere a tank can sit above the pots – greenhouse, polytunnel, patio or grow tent. Pick one, two or four pots, fed from a 45L round reservoir or a 60L flexible tank.

What's Included

• GoGro 25L 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

• Room for bigger plants – 25L of root space for vigorous, long-season crops.
• Power-free and silent – nothing to plug in or programme.
• Weeks between top-ups – the valve feeds for as long as the reservoir lasts.
• Steady moisture – the tray floods to about 3cm and drains to about 1cm.
• Made in Britain – ABS valve, polypropylene tray.

How Do You Stop Big Pots Drying Out?

Large container plants can drink several litres on a hot day; a missed watering shows as wilting and stalled growth, while drenching to be safe leaves roots short of oxygen. GoGro replaces that with small, frequent top-ups, keeping roots moist but airy and nutrient uptake even from vegetative growth to fruiting.

How to Use

• Raise the reservoir above the supply line.
• Place the root control disc under 1.5–2L of clay pebbles per module, then fill with soil, coco or pebbles.
• Move established plants in – do not sow seed into the system.
• Size the reservoir at 5–10L per module; expect 1.5–2L a day per medium plant indoors.
• Turn each pot a quarter turn every fortnight.
