The New Self Watering Quadgrow Planter is a fantastic alternative to growing vegetables in growbags or pots, producing bigger harvests and even keeps plants watered for 14 days while you are on holiday.
Ideal for tomatoes and all other plants usually grown in a grow bag (including beans, aubergines, peas and peppers).
The 130cm long by 24cm wide Quadgrow growing system is so easy to set-up and use - simply fill the SmartReservoir and the FeederMats in the pots pull water up to the roots when they need it. The plants have access to water whenever they need it so there is no risk of the common gardening problems of tomatoes or other vegetables splitting or of blossom end rot. The Quadgrow is supplied with Nutrigrow Plant food which is then diluted to provide enough feed for the whole season.
This is a New and improved version of our best selling Quadgrow which already has many fans, including the editor of Garden Answers magazine and Kitchen Garden magazine and was featured in the Daily Mirror and Daily Mail.

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.
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.
About 5% of the water absorbed by plants is used to make glucose during the photosynthesis process.
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.

Self Watering Planters - Product Reviews
Just connect the two reservoirs using the connecting pipe and thread feeder mats from these reservoirs into the pots. Add compost, plants and covers and you're ready to go. Adding water and feed is easy and there are slots for canes if needed. An excellent option for growing sweet peppers, aubergines, cucumbers, tomatoes, pease and climbing beans.
