The Auto-Pot range of hydroponic systems are ideal for those who enjoy gardening, but dislike the work. The main feature of the auto-pot system is the unique Smart Valve. The Smart Valve only waters the plant when it needs watering, and stops when a sufficient amount is supplied. The only maintenance you need is to keep the nutrient tank topped up with nutrient solution and the smart valve does the rest. No Electricity, no pumps, gravity does all the work.
