No. I know a bunch of cops here (used to be in the military) and they say they will only respond to calls about too many plants if there are indications of actual bad shit going down, or if it's someone they're trying to put away. Even then, one or two or five extra plants are still just a fine as a plant is considered the equivalent of one gram of weed. If you're not an asshole, when they're counting your plants, they'll get to 4 and say "yep there's your 4 plants", and just not mention the others. If you have them. Considering what you can get from one outdoors plant straight in the ground, if you have 4, you won't be buying any anytime soon. And you are legally allowed to trade weed, up to 30g, if you're into more variety. If you're growing to sell, then they will be paying attention. And you can trade seeds. So to get legal seeds that aren't Bakerstreet just make friends with a medical guy who bought his seeds or produced them himself. Just don't directly pay for them. You could even trade a Bakerstreet seedling for one of his if he needs or wants an indica.
The authorities here mostly expect everyone to be committing minor offences that don't endanger others, many without even realizing what they're doing is illegal. They only prosecute when someone's watching.
