Dwc with drain and flood

A question from a fellow grower:

i am thinking about a 2 part system , and maybe u can tell me if its worth doing , i am using dwc and would like to add a drain and flood system, i would drain the water from dwc to flood and drain reservoir long enough to air out my tomato roots ,in my flood system i will put a pump to circulate the nutions before going back into dwc reservoir i just dont know if it would be worth the time and effort maybe u can help answer my question , ? thank u

ive used both and both are good , that said i think i would go with one or the other .and keep it separate and simple
