Achieve 2x bigger harvests with our best-selling Quadgrow holiday-proof planter. Place young plants in the 4 pots and fill the 30Litre SmartReservoir. Instead of watering your vegetable plants or plants on your patio each day let the Quadgrow do the hard work for you. When the soil starts to dry out the Quadgrow's FeederMats pull water up from the SmartReservoir into the soil around the roots – precisely where the plants need it - maintaining perfect moisture levels around the roots at all times. Growing your own tomatoes, peas, beans and other tall cropping plants has never been easier.
Gardeners find that their harvests are 2x bigger using the Quadgrow planter compared with growbags or pots. This is because roots are never waterlogged and have better access to oxygen. The oxygen helps roots absorb more water and nutrients which fuels faster growth and bigger harvests - the perfect way to grow tomatoes.
Because the Quadgrow Planter keeps plants perfectly watered, your plants are also stronger and healthier with no risk of erratic watering causing the common problems of root rot, split fruit and blossom end rot.
This planter is a favourite amongst keen gardeners, is used by commercial chilli farms, and has been nominated for best-saving product by Grow Your Own magazine readers.
Free Feed: Includes 2.5 Litres of award-winning Nutrigrow Plant Feed worth £10.99.
This patio greenhouse will improve the quality and size of your plants in the Quadgrow. The front and back door panels can be partially or completely unzipped to give plants plenty of air on hot days, which helps to prevent mould and fungi. During the summer, use the mesh door panel on your patio greenhouse to provide ventilation while keeping pests at bay.
There's even a sewn-in mesh ground sheet which prevents slugs and snails from entering the greenhouse. Because the ground sheet is made from mesh any water spillages can drain away instead of pooling.The cover is made to last from tough UV stable PVC, and two or more of the patio greenhouses can be zipped together to increase the size.
Dimensions: H160 x W200 x D80cm

'The Trinidad Scorpions are in a Quadgrow, definitely super planters - growth is huge in comparison to the plants in ground.' Jamie, Wiltshire Chilli Farm

Our Quadgrow self-watering vegetable planters are a great alternative to growing vegetables in pots and growbags - the perfect way to grow your own tomatoes. The Quadgrow planter produces healthier plants and bigger harvests of your favourite vegetables & fruits 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.
