Cannabis is a multi-million dollar business but it doesnt take a million dollar set up. You could grow in some secret location out in the woods some where if you'd like. But for a top notch set up you'd probably be looking at spending some where around $700 (USD). Most of that money going to a well good light and expensive electrical items of course, a simple set up though would be some where around $300 (USD) though. Well, atleast for mine it would lol. And if your living in a house (not an apartment) the only thing you'd have to worry about is saying too much to the wrong person, intense lights showing on the outside of your house, smell and heat detection. But if your all for cannabis you'll go for it :thumbsup:.
