Cool!
I've never tried hydroponics. But that store (Worm's Way) has a store not too far from my house. I love to go there. They just have the most interesting stuff! From grow lights to potting soils...every kind of growing media... propagation stuff...containers...organic ferts...composting stuff... I go there to pick up one single item, and end up spending a couple of hours. And the staff is so nice.
Really, even if you have no interest in growing hydroponically, any gardener could find a hydroponic store an interesting place.
