there's the hydroponic store with a side store called Homebrew, too! off the L.I.E off kissena blvd. It's on Horace Harding.
This place is convenient but everything is about 3 times the price you will find it for online. They are really out of wack with their pricing. I live about 10 minutes away and wont go there aside from emergencies at this point. Personally I would prefer to give my money to a local, but their markup is just insane.

Brooklyn Homebrew is a godsend, after years of being reliant solely upon deliveries there's finally a viable local option in NYC. Now that they've got a storefront the selection is improving and I'm loving the fact that it's walkable from my apartment.
When I had a chance I used to stop at Kedco in Farmingdale a few times. They're mostly wine supply, but can often get you by in a pinch.
