"water source"
-Ive used RO water this whole time w/ my plants but due to security/water bill issues ive decided to switch to tap for the final stretch...mainly because i got the smallest ro filter available(does 4 gallons per hour)...and when ur up to 45 gallons a week...that means the water had to be on for 12 hours a week!(and are water bills just went up)....BUT I will go back if someone thinks this is a huge mistake...does anyone know?
