as long as people want hydroponic equipment the stores will sell them. just under a different name. like a hps and ballast might be for sale in a electrical shop as feeds will just be renamed and sold in garden centers. a lot off it you can make yourself out of things from a diy store, like a flood and drain system is very easy to make. this new law won't have that much of an effect. people will just work around it's the same as shutting down the head shops the salts they sold are all over the streets and they are easier to get as drug dealers don't ask for ID at all. all they've done is got rid of the shops the problems are still there and they aren't going away
