On the left is a flood and drain system in lava rock, on the right is constant flow troughs with 3" net pots.

Close up of the net pots.

After 4 weeks of growth you can see that most of the plants transplanted into the lava did not survive but the seeds planted in the trough are doing ok. So far I'm only using small gold fish in the tanks below.

8 Weeks in and we are eating fresh tasty lettuce on a daily basis.
