Depending on the strain just one or two plants could stink up the whole house. To insure a smell free place you would need to equip yourself with a carbon filter or ozone generator
When growing weed indoors you have to go about it the right way, or not at all. If you only do it half right then you have half a chance of suceeding. You get caught or your plants don't grow right.
The consequences for growing can be pretty severe, depending on where you live and your situation. That is to be seriously thought about before growing. Is the risk really worth it?
Rentals aren't ideal for growing, because like you mentioned landlords can pop in anytime. Emergency visits can take place in the event of an too. Say, the plumbing bursts..he doesn't wait to call you, they go in.
Freah weed has a very strong and distinct odor. If your meth head neighbors smell this, trust me they know what it is. And that could be extremely dangerous to you..I'd be more scared of them than the cops! ANy type of hardcore addict will do anything and I mean anything to get their next fix. I guarantee you that if they smell it (Growing weed odors have a wonderful way of penetrating through walls and floors) you will be visited by them or some aquaintances sooner or later. You would be better off having some old gramma living next door who has 911 programmed into her touch tone phone.
There is a cost factor involved with growing weed. Yes you can grow weed with minimal expenses. But you reep what you sow (or is it sow what you reep

) Anyways, yeah don't expect much harvest at all from that. In my opinion the results is most definately not worth the risk in that case.
If you put more money into it, then you have higher chances of getting a decent yield. But fancier installations take up more room, make more noise, smell more. So then you gotta invest in odor and sound reduction....
I'm gonna shut up now mainly because I keep zoning out..I've been trying to write this for half an hour and anyways I think I'm getting long winded so yeah I'll shut up now.
