Final solution (Advanced Hydroponics, NL)

Hi dear RIU community,

I'd like to know if there's any member here that has some sort of "proof" (read: experience) of this Advanced Hydroponics of Holland: Final Solution to be something I should use while giving water the last weeks. As you can see in the pictures, no nutes "allowed" simultaneously. Any information, input and/or opinions (even guesses) are appreciated. Thank you in advance!

Yours,

Tomas​

just a pump,

maybe someone have used it?
