Sorry, been tied up with school (adult student) I am going the bubbleponic route, one tote, 2 plants, not a recirculating system. I'm going for a perpetual harvest setup so in 4 weeks I'll get another tote, create another complete setup so all systems are independent. One pump with an air intake so air is mixing with the water, an air pump with two air stones, 15gal tote with 2 net pots. I think it's a legit setup. Thoughts?
