I had the water level about an inch below the bottom of the net pot and the net pot itself has a riser of about an inch and half where the bottom of the rapid rooter sits. They’re the current culture 6 inch net pots. The past two times I’ve ran into the same issue where it took too long to get them started but once they finally agreed to meet up with the solution everything took off and the plants did great.You probably have to small gap between the net pot and water level. Netpots should be dry in DWC, not constantly splashed with water IMO.
Most common beginner error is running to high water level starting out in DWC. Treat it like drain to waste(water through the netpot) and let the roots find their way to the reservoir. More bubbles and air is not necessarily better, just enough to saturate the solution with dissolved oxygen is the best amount.
Assuming you top feed until the roots make contact?You probably have to small gap between the net pot and water level. Netpots should be dry in DWC, not constantly splashed with water IMO.

Yepp! I start with very little aeration. You can increase aeration slightly as they grow but the most common root for failure except pythium root rot is running a to wet main root core that never get dried out causing an environment for pathogens to grow in DWC. Kelp extract and Silicate supplements helps keeping root rot at bay and so does water chillers and oxidizers.Assuming you top feed until the roots make contact?
They had popped out. Quite a few of them actually. They all just decided to stop right above the water levelWhen I ran RDWC the roots really took off at 400 ppm. If she is still growing, roots will pop out.
Turns out that my issue was running a sterile system… Running sterile has worked for me on a number of grows but this time the roots wouldn’t accept even the smallest amount of chlorine. Drained and rinsed the system, made up a new batch of solution with ORCA ( had it kicking around) just to try and the roots took right off.I had exact the same issue in NFT. Mine issue was all about water contamination with aluminium and other toxic metals.
Do you use everything plastic/rubber/stainless steel?
There is no reason for roots not growing into water unless something is killing them.
