I've had 2 successful and one failed dwc grows but the failure I believe was partially due to my own doing and also the plant just stalling out. So far this time things seem to be doing well. I got 125g off a Tyrone special in 60 days back in 2017 fwiw. I am watching ph which is riding at 5.8 and I'm adjusting as needed checking every hour for the first 6 hours then every 12 hours and adjusting but it hasn't needed to be adjusted as the maxiseries is ph buffered and balanced and with my water and everything I add it perfectly balanced to 5.8
