EasyFeed style automated nutrient delivery system indoor or outdoor

Selling a custom made nutrient dosing system. No more mixing nutrients, no more reservoirs, or circulating pumps, no more spilling nutrients everywhere. Just drop the tubes from each of the four dosing units into the nutrients of your choice. The Dosers are fully individually adjustable from 4ml/gal to 35ml/gal.
The system is comprised of four Dosatron Hydroponic Dosers a Hanna Instruments continuos combo meter to measure nutrient solution pH and concentration continuously. Monitor input and output water pressure on the gauges. The Dosers are powered by water pressure. There is an inline static mixer after the Dosers to insure evenly mixed solution. It has a four way manifold with 4 seperate timer controls through an irrigation controller. It also has two hose attachments l, one before the dosed for clean water and one after for manual hand feeding. I`ve used it for large greenhouses and small indoor grows. Hook up your indoor driines to the timed manifolds and have the ability to eater hundreds of plants without ever measuring any nutrients again. Easy to clean by running citric acid through in between cycles. Easy feed systems brand name version of this product would cost over $6000.
