many thanks for your reply, ye the pump has no adjuster its constant its a grow tank100 system all them are siting just level with the squares am only using root booster at min they wouldn be ready for any feed yet, plus there auto flowers which isnt good, i checked the ph its 5.7 which is ok he cubes are well moist, think my mistake was i didn put the bigger cubes in the propagter for while first which is why there so slow

NFT PROBLEM Hi there i placed my bigger rockwool cubes in my ft system, the first stage went very well with them having there roots come out in smaller cubes before transporting them, its been ten days and they haven got any bigger? When I looked yest they all had roots but there siting flat on the spreading sheet, when i cut the squares for them to go into they slipped down, my question is in hydroponics do the bigger rockwool cubes need to be hanging above the spreading sheet?? Can theu stil survive?? Rating: 5
