The eco-friendly Quadgrow Self-Watering pot is made from recycled plastic and has a positive impact on the environment by re-using water as it constantly feeds your plants. This self-watering plant pot is the perfect way of becoming self-sufficient as its easy to grow your own fresh fruit and vegetables for the whole family.
Harvests are 2x bigger when grown in a Quadgrow self-watering planter compared with grow bags or pots because it automatically waters your plants for 14 days at a time. Even better, it does it all without electricity or timers!
Each Quadgrow holds 4x plants and includes everything you need.
Why this self-watering pot works
- The Quadgrow self-watering pot automatically waters plants, keeping soil at the perfect moisture level, never too dry or waterlogged.
- Perfect moisture means roots have better access to oxygen which fuels faster growth and bigger harvests.
- There's no risk of erratic watering, which means much less chance of root rot, split fruit and blossom end rot.
Self Watering!
The FeederMats pull water up from the SmartReservoir into the soil around the roots – precisely where the plants need it - maintaining perfect moisture at all times. Growing an impressive crop is easy, and there's no need to worry about holiday watering.
If you want to leave your plants for longer than 10 days in the summer either ask a neighbout to pop in and top-up the SmartReservoirs or link a water butt to the Quadgrow(s) using the optional Water Butt Link Kits. These kits include everything you need to connect a water butt to your Quadgrow including a water level controller which sits in the SmartReservoir and all the pipes and connectors. When the water level drops in the planters reservoir more water is pulled from the Water Butt.
Easy to use
- Place the Quadgrow's FeederMats in the 4x 11 litre pots, add compost, plants, and add water to the SmartReservoir which sits below the pots.
- Your plants will be perfectly fed and watered for around 14 days at a time.
- We include free award-winning Nutrigrow plant food with feeding instructions. The feed will last you the whole season!

Ask us a question
Our Quadgrow self-watering planter is a great alternative to growing vegetables in pots and growbags and is the perfect way to grow your own tomatoes.
The Quadgrow self-watering pot produces healthier plants and bigger harvests by providing 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 a 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 critical functions.
1: Transporting nutrients and glucose
Water is needed to carry nutrients from the soil and glucose from the 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 often and therefore it won't photosynthesise as much, which will lead to lack of glucose and stunted growth. Sunny, hot weather and windy conditions increase the rate of water loss through the pores, so plants need more water in these conditions.
