Grow bigger crops with our Duogrow self-watering planter which keeps plants perfectly fed and watered.
The eco-friendly planter has a positive impact on the environment by re-using water as it constantly feeds your plants for up to 2 weeks at a time. It is the perfect way of becoming self-sufficient so that you can grow your own food for the whole family.
Your Duogrow harvest will be on average 2x bigger than that produced by growbags or pots. Your plants will never go thirsty, even when you're on holiday and the soil won’t get water-logged.
The Duogrow self-watering planter is easy to use. You simply place the FeederMats in the pots, add compost and plants, and fill the Duogrow SmartReservoir that sits below the pots.
The FeederMats will pull water up from the SmartReservoir when the plants need it, keeping the soil perfectly watered for 2-weeks at a time without over-watering.
Plants in a Duogrow planter are healthier and stronger because there's no risk of erratic watering - the cause of root rot, split fruit and blossom end rot.
Ideal for growing your own veg on a patio or in a greenhouse.
The pots are 30cm wide and hold 12 litres of compost each, giving roots plenty of room for healthy growth.
Our specially formulated Nutrigrow Plant Food makes up 416 litres of diluted plant food and contains all the nutrients plants require to thrive, so no need for Tomorite or other plant supplements.

Made in England
The Duogrow self-watering planter produces healthier plants and bigger harvests than traditional pots and grow bags by providing your plants with constant access to water without ever over-watering.
What happens when we overwater?
Overwatering prevents roots from accessing oxygen and is the number one cause of plant demise.
When soil is over-watered the pores in the soil become blocked and the roots can't access the air in the soil. Roots need access to oxygen in order to absorb water and nutrients, so lack of oxygen means that the roots can't take up water or nutrients. A plant weakened by overwatering is susceptible to disease, particularly fungal attacks. If the over-watering is repeated the roots suffocate and die.
What happens when we under-water?
Underwatered plants don’t have enough water to make glucose for photosynthesis, for developing cells and for two other often forgotten critical functions.
1: Transporting nutrients and glucose
Water is needed to carry nutrients from soil and glucose from leaves to the other parts of the plant. This is why the calcium deficiency blossom end rot is often caused by erratic watering even if there is sufficient calcium in the soil but not enough water to transport it to the tomatoes.
2: Accessing carbon dioxide
Plants access the carbon dioxide they need for photosynthesis by opening the pores on their leaves and stems. When the pores open they also release water. If the plant is short of water it won't open the pores as frequently and therefore it won't photosynthesise as much, which will lead to lack of glucose and therefore stunted growth. Sunny, hot weather increases the rate of water loss through the pores, so plants need more water in these conditions.
