@sree for the right plant it’s hard to beat kratky. In my last place I had a setup growing constant salad green year round with minimal lighting. The key was the distance from light to plant. My use case was about quality, not cost. We can’t get fresh salad greens up here - they’re just half dead by the time they get to northern Canada. Kratky is awesome it just can’t support slow growing or long-term growth (with a few exceptions).Anyway: good luck!
