Mornin @potpotpot,
If you are shopping for a new growing technique I’m gonna suggest that you consider the micro octopots that many of us are using. I switched to these from my Big Pot Supersoil grows and have had success from the very first run.
They grow big plants with minimal effort and, if you hook them up to an autofiller system you can literally put the system on autopilot and walk away for a week or two!
Here’s a thread by @firehead that provides details.
