Get to know your neighbor. You don’t have to be best friends. Offer him a beer and just shoot the shit with him. Fake an interest in growing. (Over time) Is it hard to learn? Is it expensive? Could you make any money? Must be hard to control the smell, what about thieves? Etc. etc.
Coming up on my 61st year in a few months. Put my first plant in the dirt in ‘73, actually found it growing in the dirt at the edge of a parking lot at a local dive bar and transplanted it to a more “secure” location. Been growing off and on ever since.
Some growers use a light cycle known as the gas lantern routine (GLR), where they interrupt the “night” portion of the cycle with an hour or so of light. Never tried it myself but you can google it for specifics.
