I'm from the uk and I was wondering what the law is in the U.S. regarding seed sales.
Here in the uk the law is crazy, and it is legal to sell seeds, it is legal to buy and own them. The loophole is that they are souveneirs, but it is illegal to germinate them.
So you can walk into a hydroponic store and buy an ebb and flow, nutrients, lighting and a pack of 10 seeds, probably to build a type of museum with everything laid out and the lamp on but never actually germinating.
