I am looking into getting a dosing machine. Or controller. Has anyone found one that works good with a little better price range than $1700.00? Or haVE ANY INSTRUCTIONS ON HOW TO MAKE ONE?
FERTILIZER INJECTOR...dosatron
You hook it up to a water line and it picks up ferts along the way..You can set dosage strengths from 60ppm and up....ferts are mixed in a 5 gallon bucket and picked up and injected into the h2o.
