DIY Lettuce Raft System

Taxonomy upgrade extras: 

Next , future project...

I'm feeling the urge to grow lettuce, more than the 7 pod system can supply.

The next conversion is for a 'raft' system, this comprises styrofoam (or similar) which floats on the surface of the water in a rubbermaid type container. In the foam you drill several holes and place net pots into them, probably 2". In the net pots go rockwool with lettuce seeds/herbs in, backfill with hydroton grow rocks for stability. Nutrients, as usual, will be the General Hydroponics Flora 3-part range.
