well... DWC seems simple if im using a 5 gallon bucket with a hole cut in the lid to drop a net pot into... then all i really need is a little aquarium pump
and some way to measure the level of the water without opening it
however, that aeration pump would be constantly running, i think a drip system
works on a timer.. so its running less, but requires a timer, a bit of a tradeoff i guess
which size net pot would be neccessary to hold a tomato plant grown in a 2x2 foot cage?
also.. heres a little drip vs dwc question... should power fail, what will die out quicker?.. dwc wouldnt be able to aerate the liquid, and drip wouldnt be able to supply it
