Upgrade your planter to get a better tomato harvest this season. Have a look at our other Tomato Growing Kits.
Our best selling planter gives you bigger harvests and holiday-proofs your plants. This set of pots cleverly keeps your plants perfectly fed and watered for up to 2 weeks at a time thanks to the large SmartReservoir and FeederMat controlled watering, so you raise healthier plants with bigger harvests.
Why harvests are bigger in a Quadgrow planter...
Quite simply they get the watering balance right for you. Plants need enough water to take up nutrients into to the plant, but if there is too much water the roots don't have access to enough oxygen. Incorrect watering causes the most gardening problems, including blossom end rot and fruit splitting.
The SmartReservoir holds 30 litres, plenty to keeps tomatoes perfectly fed and watered for several days at a time.
Simply fill the SmartReservoir and let the FeederMats in the pots pull water up to the roots when they need it. Although the plants have access to water whenever they need it, roots are never stood in water, so access to oxygen is never limited.
So, that's no more holiday watering rotas, and definitely no disappointing harvests caused by erratic watering. The Quadgrow is an ideal replacement for your traditional tomato pots or grow bag.

The Quadgrow produces healthier plants and bigger harvests by providing your plants with constant access to water without ever over-watering.
Plants need to constantly replace the water they use, but overwatering prevents roots from accessing oxygen and is actually the number one cause of plant demise.
What happens when we overwater?
If soil is over-watered the pores in the soil become blocked and the roots can't access the air in the soil. The lack of oxygen means that the roots can't take up water or nutrients. A plant weakened by overwatering becomes susceptible to disease, particularly fungal attacks. If the over-watering is repeated the roots suffocate and die.
Perfect for?
Tomato plants – The Quadgrow is the perfect replacement for traditional tomato pots and tomato planters.
What happens when we underwater?
Plants use water for cell growth and for overall health, but they also need water for the following specific functions, which are compromised when we under-water.
Transporting minerals and nutrients
Plants use water to move minerals and nutrients from the roots around the plant, and to move glucose (from photosynthesis) from leaves to other cells in the plant.
Photosynthesis
About 5% of the water absorbed by plants is used to make glucose during the photosynthesis process.
Transpiration
As well as water, plants need carbon dioxide for photosynthesis (they combine water, carbon dioxide and light to produce glucose). They access this carbon dioxide through microscopic openings on their leaves and stems. These openings are called ‘stomata’. The stomata open and close regularly to absorb carbon dioxide and as they do this they also release water, this release of water is called transpiration. If the plant is short of water it won't open its stomato as frequently and therefore it won't photosynthesise as much. Sunny, hot weather increases the rate of transpiration, so plants need more water in these conditions.
It's no wonder then that incorrect watering causes most gardening problems, including blossom end rot and fruit splitting, such as when growing in traditional tomato planters.
