50 sq ft AND only 1200 watts... but yeah, for real needs type growing, that should be enough if you grow even decently.
And the kids thing... it's a parallel... I'm also not saying you're wrong regarding the issue, I've never been in that situation, so I don't know, but given the things I am aware of, like the underage thing (which, how is it my fault if an adult buys a keg for his kid's kegger? but it's an ass-load fine to the seller anyway I'll tell you, possible loss of license too). Unless you personal know of someone who's been charged with the crime and beaten in court, all we're really saying is it hasn't happened yet, and that we think it shouldn't happen, and won't, but I'm not a lawyer or up on all the regs, especially with it being soo all over the place by County, then city... I get proven wrong a lot, you just did, maybe we all will be about this next week, when someone does get busted for selling meds that got sold off on the black market...
I am suggesting he be better safe than sorry. He's obviously concerned about that.
