i agree with some of what has been said. i am willing to bet that a vast majority are at least *trying* to grow a plant, as that is the main reason for seeking out help. you're afraid you're going to fuck up, or you already have. or you have a paranoid fit cus you aren't prepared and you suddenly realize it, etc.
but let's not forget how widespread the illegality of our medicine is, which is going to produce a legion of people who "fancy" the idea of growing their own, considering how expensive it is... but they never really do cus let's face it.. breaking the law for the first time can be scary. not everybody has a zen moment and realize that they want to preserve the species, or realize how non-scary it really is, or live in canada
i am sure though that there are a lot of people who actually do the reading and realize that growing is either not going to work for their situation, or is going to wind them up in jail.
for instance, i bet hundreds of people per day read enough to find out that they're gonna get caught on the smell without a proper carbon filter.
anyway, it's just as common for me to see people that are clearly not ready for what it's going to take, but who are trying anyway. i feel bad for the plants more than anything, usually
