I grow in a rented house. It's pretty stealth in my closet in my bedroom. Basically no one is ever anywhere near my bedroom other than me and my gf ,so I don't worry. Een if you went into my room, you would need to open my closet to know anything was going on in there,
That aside, The thing you have to do with a rental ,Is go the first year without growing at all. This way you can see if you have the type of landlord that checks up on you, or pops in randomly to see if things are ok. My landlord gets payed by direct debit every month and we never see him at all ,he goes through a letting agency and we never see them either ,just a once a year check of the house and then sign a new contract, but if I had the type of landlord who was always coming over ,I probably wouldn't risk it.
Oh and yeah I haven't got that on my contact about coming in without notice, if you do have that its a definite no go.
I might also add, I am from a place where if I get caught with 1 or 2 plants ,I won't go to prison. So by knowing that my landlord doesn't do inspections, and knowing that I won't go to jail for a first offence for a personal grow ,i'm taking a calculated risk. I also play it smart and keep it a secret.. so .. the odds are in my favour.. this may not apply to you.. just use your brain and work it out for your situation. It's only insane to grow in a rental if you've just moved in and don't know your landlords visiting habits.. but if you think you have things worked out and keep the shit small and secret.. I would say why not. Like if you do 1 or 2 plants, even if you have to you can tear them down easily and get them away... do 10 plants and you have a problem.
