I would try a smaller container or add more perlite to my mix, then they will dry out faster so you can feed more often. Like Zipcode said, some grow in Rockwool, Coir, clay balls, it goes on and on. Trial a few systems, methods, ferts, we learn best by stumbling forward over time. Good luck this year.
