7 year soil farmer just converted to RDWC for very first time after reading alot about the undercurrent system. OK so I just built a DIY undercurrent system using 27 gal totes from home depot. 2 totes under each light(4 1k watt in 1 room) 4 slots in each tote. I hear alot of people saying to be very modest in the UC system. Any recommendations on PPM per week? I use half RO water and half tap water so my ppm is about 125. What should I start rooted clones on? 200? and how much should I go up weekly? I am reading very low numbers on most peoples threads. And I'm using FLora Nova grow and bloom with bloombastic at the end, probably at half strength. debating on using hygrozyme as well. Anyone use Flora Nova grow and bloom on the UC? Any advice and tips would be appreciated.
