Hey Dejayou,

I was in a similar water hauling situation and using 2 1/2 gallon (about 10 liters) cat litter containers. This got old very quickly. What I ended up doing was getting 4 x 20 gallon containers (2 for each room) that I fill once per week (actual volume depends on how much liquid I think I'll use.. hate to waste nutes!). In regard to the suggestion to use R/O water, cool if you have it. Me, I fill my cans and let them sit uncovered for 24-48 hours to: 1, let any chlorine evaporate (turns to gas), and let he Ph stabilize before I add nutes or adjust. My water comes out of the tap around 125 ppm.

Peace, Farmer Rich
