Flood and drain - also known as ebb and flow - is used world wide for fruit, veg, and herb production. A popular system for the bigger plant grower due to depth of grow table. However this hydroponic system will grow any plant happily. The kit consists of grow table, tank/reservoir, nutrients, pump, pH adjuster kit, spreader mat, timer, clay pebbles, reflective top sheet and full instructions. In short, the grow table filled with clay pebbles is flooded with nutrient solution and drained on regular cycles. Some say the yield and rate of growth can't be beaten. When applied and maintained properly this speeds up plant growth two fold and can quadruple or more the yield compared to soil. Very low maintenance required. Designed and manufactured in England.
