Autopots are a great way to supply your plants with the nutrients they require, without ever having to use pumps or other electrical equipment. Instead, Autopots rely on gravity and the ingenious Aquavalve to distribute nutrients as and when they are needed. Because of this, Autopot kits are simple to install and very user friendly.
Aquavalves fill trays up to the standard level of 20mm. Once this nutrient has been absorbed and the tray is empty, the Aquavalve automatically refills it back up to the 20mm level using an ingenious float valve system. Fresh nutrient solution is only ever delivered once root systems have absorbed the previous 20mm of feed.
Because Autopots are fed from underneath, they require a medium that is able to absorb liquid effectively, ‘sucking’ it up to the upper regions of the container and creating an even spread of nutrient. Coco coir ticks these boxes, making it the best performing medium we’ve tested for use in Autopot systems. It’s also advisable to mix growing mediums with perlite, up to a ratio of around 4 parts medium to 1 part perlite, particularly when using heavier potting soils. Even coco grows benefit when the medium is mixed with perlite at a rate of around 5:1 (coco – perlite).
To check that the Aquavalve is functioning properly, hold it at eye level and take a close look at the yellow silicon which is fitted into the top float. In order for the Aquavalve to function correctly, a tight seal should be formed between this float and the hole that sits underneath it. If it doesn’t sit properly over the hole, lift the top float up, remove the yellow silicon and give it a quick clean. When you put it back into position it should form a tight seal.
The Aquavalve should be cleaned after each grow using warm soapy water and a cloth.
