Hey RIU.
I have a 8 pot RDWC Setup.. 20L Buckets and with 32mm pipes connecting them.. I've run into the problem with pipes getting clogged by the roots! and causing flooding.. Im at day 31 of flower and 2 months of veg before that.. It is very frustrating not being able to leave my water pump...
Damn that is alot of gear your using.. I have a RDWC setup and im only using GH Trio and Hard water.. Nothing else.. I like to keep it as simple as posible..
