I was thinking about you while setting it up
@Milson . Check this out. If you have different staged plants and different needs, just for when they flower and need more effort to feed you could use this
Single auto pot kit
I know obviously no good as it's in the UK but to give you an idea, paint the tank white so it reflects light and you could save yourself a fair bit of time and effort.
They even have air dome attachments so the roots get extra O2 but I just put holes in the pots, they also have fabric pot versions too.
I just remember you saying it's no good for your needs, but I think using multiple singles would work well. Once you've seen what one kit actually is, I'm sure you could find the same size or smaller than 47L if that's easier little kitchen garbage bins for reservoir and little plastic trays to hold your pot and the aqua valve the auto pot uses and save quite a bit of $$$ making them yourself.
Just a few drill holes and tubing to connect it all, the cheaper single valve I got came with it all except a tank for £13 on ebay.
A plastic garbage bin is £3 ish so for £20 including pot and tray You can make a £40 (obviously in dollars I'm not sure what it would be in the US but I'm sure they're just as cheap) set up that will last years and They even go through the wet /dry cycle too. And each plant can drink what she needs.
Just a thought mate.
Sorry because I know you will spend time researching now but I promise it's worth it
