I am looking at a 10-12 gallon sterilite or rubbermade container for a DWC system. I intend on using either 6 5-inch pots or 8 3-inch pots (undecided) for lettuce.
I intend on setting up 2 of these DWCs and using a dual pump I have to power air stones in each reservoir. This will complement the ebb and flow and will allow me to have lettuce in various stages of harvest. I don't need another ebb and flow at this point and don't need the expense of another submersible pump.
My question is this......based on experience, what are the advantages and disadvantages over these building methods:
1) Using the plastic lid with appropriate sized holes for the net pots to fit
2) Using a 1.5 inch thick piece of styrofoam with the holes cut for the net pots to fit?
Seems like a dumb question, but any experience on one versus the other?
