I just got my 3 x3 econotray.Have used DWC in the past. How much water/nutrient soln goes in the resevoir ? How often water/nute changes (Using my small DWC I changed H20 weekly using r/o water from culligan)
Im wondering if the netwell insert was worth the $$, doesnt seem to keep the netpots very far off the bottom.
