Was thinking about pulling a couple old Ebb & Grow systems out of retirement but hate dealing with hydroton. Was toying with the idea of using rockwool. Plants are vegging in 4" wool cubes then would be transplanted into the the Ebb & Grow just for bloom. Was gonna do a 2" layer of hydroton and back fill with Grodan Cubes (rock wool dice). Thoughts?
