I just found this nifty little thing if your willing to drop $200 on it, but to a lot of us hydro people that aint shit. It looks easy to use with two set points for your high and low ph ranges and two 110 AV outlets on the top. plug one pump into the first outlet for a base rez and one pump into the second outlet for and acid rez, hook them seperately to two flow conrol drippers which will drip every every 5-10 seconds when activated by the controller. Place these above your water level and its like your sitting there adjusting the ph yourself. Get a gravity rez and you may never have to go in your grow room again. Peace
