I use an ebb/flow garden with a 25 gallon reservoir. My first two flushes I had not installed an air stone yet. When I emptied the res, the water was colored stronger towards the bottom of the tank, and the surface was coated in a darker "sludge."

After adding the air stone, the solution stayed consistent in coloration with no build up on the walls. The plants seemed much happier! Cheap improvement with great results.
Mr. Champ Reviewed by Mr. Champ on . HOw does nutrient work in hydroponic? Some help plz! :wtf:HI, I'm a first time grower using an ebb and flow hydroponic system Iā??m using drrockwool for my hydroponic system. Iā??m going to use a drip system for my veg room now and an ebb and flow for my flowering room when my plants get into the flowering stage. I was inspired by the "green man's growing cannabis" on youtube. I'm just wondering how many times the pump should pump into the rockwool (according to Mr. Green's youtube video, Mr. Green says three times a day, 15mins each Rating: 5
