Take a look at @GrouchyOldMan 's auto topoff setup for the micro octos. i REALLY like the execution (kinda like a multi-bucket RDWC / DWC thing). Float valve sits in its own ātubā, all tubs are same level, water always finds its own level. No roots in the float valve tub to create accidents. Iām even looking at that design and thinking add nutes to the float valve res for all, and with a small enough pump you could have a slow drip top feed.
Some plants are super thirsty. I have a frankenstein cutting, well now its a bush, here, and she easily drinks a gallon a day (full reservoir), so its either refill daily (currently), or modify to the auto topoff and mainly deal with nutes.
