Grow bigger harvests with our fabulous Duogrow planter, which keeps plants perfectly fed and watered for 2 weeks at a time.
How it works
Place young plants in the 2 pots and fill the 25 litre SmartReservoir with water. Instead of watering your plants every day, the Duogrow will do the work for you. FeederMats pull water up from the SmartReservoir into the soil around the roots, exactly when and where the plants need it. This maintains perfect moisture levels around the roots at all times.
You will be picking twice as much veg using the Duogrow compared with growbags or pots. This is because the roots are never water-logged, and have better access to oxygen. This helps roots absorb more water and nutrients which fuels faster growth.
The FeederMats ensure that there is no risk of erratic watering, which often results in root rot, split fruit and blossom end rot. The pots hold 12litres of compost each, giving roots plenty of room for healthy growth.
Perfect for growing all the plants you would usually grow in a pot or growbag – tomatoes, beans, cucumbers, aubergines, peppers and any tall cropping plants.

The Duogrow 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.
