Recirculating dwc or stand alone dwc pots?
Dwc pots stand alone might be a bit crowded to get in and individually adjust feeds do routine checks on airstones…
Recirculating however you would only need to access external resevoir to ajust ph… I love r-dwc but my personal favourite is flood and drain(ebb & flow) to main resevoir …I just find less problems but however my personal best yields have been R-dwc

R-DWC Is the way I am planning to use top feed system not sure which brand of kit I'll get yet? Getting close to harvesting my 12 plants in greenhouse, they are staggered so I won't be buried in work all at once!
