The AutoPot® 4 Pot Kit


The enjoyment of growing with hydroponics is within your reach. Autopot® Systems allow everyone to experience professional results from hydroponics. Forget about the complications, complexity and problems of conventional hydroponics systems. Simply plant seedlings or seeds, fill the tank with water, add a measure of nutrient and watch the spectacular results. The results could be on your table before you need to top up the tank again.


Autopot® Systems are a patented technique of hydroponics that differs from conventional methods in a number of respects that make it versatile, effective, inexpensive to run, capable of operating in a wide range of locations where conventional hydroponics may not be effective and capable of being used by everyone from school age upward. It's the ideal way for busy people to experience the benefits of gardening and provides a huge return in pleasure and produce without a heavy commitment in time or the problems of requiring a specific program of attention.


There is an Autopot® growing solution to suit everyone from the novice through to large commercial users. Most first time users start off with a gravity fed system due to the simplicity of only having to position a supply tank higher than the growing module. Once the collection of Autopot® growing modules have expanded beyond 20 or so units, consideration for the pump fed methods becomes more practical to reduce the frequency of having to top up a gravity tank. Having said that, it does not mean feeding large number of plants by gravity is no longer a viable option - click here to view a commericial Autopot® farm feeding 20,000 plants by gravity. The choice is yours!


If you want to start with a bigger system, the Autopot® 4 Pot Kit gives you some more options for growing more plants or different varieties using our most popular growing unit - the Hydrotray Single 12" module.


The AutoPot® Smart-valve

The Smart-valve is the heart of AutoPot® Systems - this unit controls the water level in a module (or your own tray) to give your plants the wet-dry cycle. Over thirty years of trials, refinement and development have resulted in today’s Smart-valve.

The Smart-valve and AutoPot® Systems have won a number of awards including the Inventors Association of Victoria, Australia, First Prize in 1992 and the best Victorian invention at the Royal Melbourne Show of that same year. 


How does the Smart-valve work?

Unlike a conventional ball cock type float valve, the Smart-valve allows total reduction of the fluid level before it refills. When connected to a low pressure water supply (which can be from either pressure reduced mains, pressure pump (like the AutoPot® Smart Pump Set) or gravity tank, the Smart-valve opens to allow water to enter the bottom of the growing container to a set depth (approx 35mm).
The Smart-valve then closes and will not permit further water to enter the container until all the original supply has been used up by the pot. This absorption is achieved by capillary action that occurs in the growing medium. Once the water has been absorbed to the extent that the film of water under the Smart-valve has gone, the Smart-valve re-opens and another supply of water enters the growing container, thus we have wet-dry cycles dictated by the pot's own rate of consumption.


AutoPot® Hydrotray Single 12" Module


400mm x 340mm x 290mm -


This module is designed to take a single pot, thus allowing more control over the spacing of the plants. It is ideal for growing larger or deep rooting plants. This green 12" module uses a fitted valve cover to locate the Smart-valve in the tray.



Extending the system is simple - several units can be fed from a single reservoir. We recommend to feed not more than 4 units from a 35 litre Hydrotank.
