where is heath lol?? if a plant has 10,000watts over it and your hitting 2gpw does that mean you will get 20,000grams then??
In the early nineties I was growing and experimenting with dripper systems, after running things for a while I noticed that if I increased the flow rate to the drippers the plants grew and flowered more quickly.
This led me to install bigger and larger bore dripper pipes, I had just modified one system before I went away for a week, when I came back the plants were all much larger as expected but what I didn't expect was the flow rate had been too high and as the roots had grown the roots had blocked the drain and were growing fully flooded! that's when I had a eureka moment and went and bought some brewing and builders buckets and started experimenting.
The basic idea is very very simple you basically have a bubbler bucket but instead of having the nutrients just sat in the tub you recirculate them at a high rate from a external rez so the nutrients are in continual motion.
Here is a Waterfarm bottom modified to recirculate the nutrients.
in this picture you can see the water entering the bucket from the right through a half inch fitting and exiting through a 1 1/2" fitting this picture shows nicely the sort of flow I like to have through the buckets.
