I have a 20 gal reservoir. Only using 15 gal though. I use canna aqua. Spending $130. to 150. a grow. I was thinking of changing if cost savings was high enough. I heard some fert. U have to flush once a week cause of salt. I don't have to do that. I only have to adjust ph 5.3/5.5 when i do water change. It slowly creeps up to 5.7/6.0 during the week. Its been easy to use, but might switch if I am spending twice as much. Hygro hybrib gave his formula he uses. Im just not sure what it would cost. Thanks for any info !
