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.
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.
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, such as when growing in traditional tomato planters.
