Most hydro shops Just give customers that are asking or hinting to a Marijuana subject a Blank stare as if to say "Duh"! I know the folks at my local shops just play "deaf" to any weed growin' questions. Tomatoes are a good Name because they both grow straight up, have side branching, produce a "flower" and fruit (nuggs). They really don't need to know what specific plant you're growing except for: Indoor/outdoor, soil/hydroponic, organic/juiced up, seedling, vegatative, flowering, etc. And if you're a regular customer, over time they'll know. But its just business to them. They just want to sell it to you, and help you to be successful in alll your growing. Ain't that nice? Peace
