Never saw one of those, by the time i got to this part of the post, i was thinking of making something like it.....but now i see what it is, VERY nice thing. You get that set up at a hydro store? i got to get me something like that.....is it just for hydro? or are those pellets going into soil?

Thanks for posting the pics of the full set up.
great grow you got going, great variety too!
