The trial

For a couple years my brother Dan was a maintenance engineer at a produce processing plant. He did a system retrofit and brought me some of the stuff being thrown away. This flood and drain planter is a piece of 6″ schedule 40 pvc pipe. The ends are survey caps purchased at a local plumbing supply warehouse.

The really sick looking plants are the result of neglect on my part . . . pulling one system apart and putting another together with too long a span between stressed the plants. They’re recovering. The tomato plants are purchased and are my test subjects. The tank holds two goldfish, not quite enough to supply this many plants with nutrient.

One of my concerns with media this light is its ability to hold the plants in place as they grow and produce fruit. I will have to run retaining lines between the support ropes.
