DWC or Deep Water Culture is the process of growing plants with the roots submerged in water at all times. You have to supply lots of Dissolved Oxygen to the roots or you will kill them very easily. Once you experiment with DWC or RDWC, you will never run Ebb and Flow again. The growth rates in RDWC are like nothing i've ever seen before. In my side by side comparisons when I put 16" topped plants onto E&F and the same 16" topped plants from the same Mom in RDWC into flowering, under the same conditions, the E&F plants max out at 36" while the RDWC grows past 56". With 12 plants in RDWC under 2 x 1000 watts HPS, I get 72.5 ounces with a 10 day VEG and with E&F I average 48 ounces with a 2.5 - 3 week Veg. There is no comparison at all. Plants can die very easily in DWC and there is no room for error at all.can anyone elaborate on this ?
