Quadgrow-Plus is a great alternative to messy grow bags and it even gets the watering right for you. The 4 pots are used for tall plants such as tomatoes, beans and cucumbers and the central planter is ideal for salad crops such as radish, spring onions and lettuces.
The planter holds 30 litres of water in a smart reservoir that releases the water to the roots when the plants really need it as the soil dries out. Meaning your plants won't suffer from wilting, bolting, blossom end rot - or any of the other problems caused by under and over-watering.
You can even grow salads and herbs outdoors all year in the Quadgrow-Plus by adding the mini greenhouse option which protects plants from frosts.

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.
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 is no wonder then that incorrect watering causes most gardening problems, including blossom end rot and fruit splitting.
