I don't have a similar hobby, but I am trying to grow myself a platform on web2 with artwork.

I do find cacti interesting so I'm gonna give you a follow.

One thing that could help is you can put your various links/buttons into a footer at the end of all your posts to be a fairly unobtrusive way to maybe funnel a few people from one place to another.

Also embedded videos still count for watch time, so doing cross posts with embeded videos could be a great way to get some views.
