It’s difficult to keep plants grown in pots and grow bags in tip-top condition especially in the summer, but these low maintenance veg pot kits keep your plants in the best of health thanks to the 34 litre water reservoir.
"The results exceed all expectations and we are highly delighted with this product. We have had great success with both Quad and Octogrows. The results are incredible." Mike and Sue Knight, July 2010
Simply add young plants to the 11ltr pots which encourage big, thick roots to develop, fill the reservoir with water and the nutrients included and let the SmartMats - which provide the constant watering that plants require - do the rest.
The SmartMats pull water up from the reservoir by capillary action as and when the plants need it and the feeder tray separates the soil from standing water to ensure quick, strong, healthy growth. Add the optional vented propagating pot lids to bring plants on and to protect them from the cold and frost.

How it Works

The automatic watering is powered by the Smart Mat Strips. These take water from the Reservoir up to the soil in the each of the pots. This ensures your plants always receive the perfect balance of water, nutrients and oxygen, putting an end to under-watering and over-watering.
The reservoir is continuously topped up by the Holiday Watering Kit thanks to a water regulator. Simply add water and our specially formulated plant food to the Holiday Watering Kit’s 25 litre bucket every two weeks and your plants will have constant access to nourishment.


What people say
"I got one of these last year and the results were very impressive - my tomato plants were much bigger than the plant in the photo.
I grew two pepper plants and two tomato plants in this and also grew the same varieties in ordinary pots for comparison. The difference in growth rate was so obvious even within a couple of weeks of the seedlings being planted. Not only were the Quadgrow plants taller, but each branch of the plant was thicker and healthier looking. My understanding is it is because the plant always gets exactly what it needs so it is always at maximum growth rate, whereas with the ordinary pots you are just guessing when it is thirsty, and how much water it wants. I got 44 big tomatoes off a single plant which hit the roof of my greenhouse and was still trying to flower in October. It doesn't need electricity or anything complicated, so I bought one for my parents too.
J. Livsey, December 2009
"Just wanted to say how great I have found your Quadgrow product this year.
I planted two peppers and two tomatoes. The pepper plants are much bigger than they would be in ordinary pots and the tomatoes turned into vines that were only slowed down by the size of my greenhouse, much more productive than the same varieties in ordinary pots too.
The best thing about the Quadgrow is not having to fiddle with water pumps which makes them great for people without electricity in their greenhouse. I have tried a few self-watering products over the last few years, this one is genius. I am already deciding what to grow in it next year."

How much will I harvest?
Bumper harvest of 7.9kg of tomatoes!
In 2009, our Gardening Angel Victoria planted Scarlatto, San Marzano, Rosada and Sweet Million tomatoes in a Quadgrow in our Greenhouse . She harvested 7.9kg from just one Quadgrow. Marvelous!
Julian at thechileman.org reports on the great results he has had growing with a Quadgrow
Julian the Chileman sent in these photos, highlighting how well his tomatoes are growing in his Quadgrow.
He is growing a heritage tomato plant in this Quadgrow pot. Compare it to the plant in the pot alongside. The small blue pot is the same heritage tomato plant potted into a normal plant pot.
The automatic watering from the Quadgrow that is feeding the lucky heritage tomato is making a big difference in comparison to conventional growing.

The image above, on the right, is a comparison from Julian's Marianna's Peace tomatoes.
The plant on the left is growing in Julian's Quadgrow and it's receiving the Greenhouse Sensation balanced plant food, included in each Quadrow.
Both varieties were pricked out as seedlings at the same time and the difference in growth rate is amazing. The biggest leaves on the Quadgrow-grown plant are the length of the small plant.
Julian has had a great season growing in his quadgrow....
