If you don't want to move, create some content for them that people can use & monetize it.

You could create a site that reviews the best dispensaries in those areas or recommend the best seeds, products, etc. for those climates.

Then, you could either do affiliate sales with related products, put google ads on there, sell ad space to companies in the area, place amazon or e-books on there for sale ...

I don't think you could sell seeds, but you could do some affiliate sales for lights, nutes, etc. - that means that someone clicks the link from your site to go to the vendor's site & you get a percentage of the sale - all you have to do is get the traffic to your site, you never handle the product at all. Same with products off Amazon.

Tons of things you can do with a good website that makes money even if you stay in Florida.
