did anyone have any luck breedimg and selling seeds online?

thinking about partaking in this endeavour.

there is obviously alot out there .

has anyone set up an online shop

Not planning anything industrial. one 4x4 and one 3x3 every few months.

small scale hows business how difficult is it to advert and gain momentum. i assume you had to set it up as a registered business for tax purposes ....

Sounds like you are describing pollen chucking, not breeding. Lots of people have been successful at it. From what I have read, learned, and seen, is that there are a handful of breeders and countless chuckers. It sounds like you are trying to make a quick buck. I would start just doing it like a side hustle and not worry about all the business end of it until you have a tried and true model and have built up a viable inventory. In the meantime, sell shit around the house you don't need.
