The only time there's the slightest resemblance to water culture is when
the
plant sends its roots down into the reservoir...

Ah, interesting! I guess I must have not read your semi-hydro page carefully
enough to get it, sorry. Out of some reason I had misunderstood and thought
that the entire plant container was filled with water and this PrimeAgra
stuff. And so then it sounded very similar to water culture. Whereas now I
finally understand that it is indead very different. Thanks for clarifying!
