Step by step how to do it. I know “auto topoffs” make people nervous, and for good reason, failures = floods. But his method with the float in its own pot, and all octos on the same level as the “float pot”, he eliminates a lot of the failure points (roots cause all kinds of problems.). I really see this method as a viable, and rather safe topoff setup… And if your plants require the same nutes, even makes that easier!
