Perfect For: Tomatoes, sweet peppers, beans, cucumbers, aubergines, peas and any tall cropping plants.
The Duogrow produces huge crops by keeping plants perfectly fed and watered - even when you're on holiday.
The planter's 2 pots contain FeederMats which pull water up from the SmartReservoir to the plants exactly when they need it. This slow watering keeps the soil perfectly moist.
By pulling water up slowly the Duogrow ensures there are always air gaps in the soil, so the roots have access to oxygen. The oxygen fuels more productive growth. Your plants will be bigger, healthier, more resistant to attacks from pests and will typically produce a 2x bigger harvest.
The pots are 30cms wide and hold 12litres of compost each. The SmartReservoir holds 25litres.
This planter has loyal fans, but dont take our word for it, read our reviews below.

Made in England
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.
