Right but that money is over a few months you said. How often can it be repeated? The slow growth is the main limiting factor. But of course you have to put the plants in front of the right people, super reds or otherwise
Theres a facebook group called "planted tank quick auctions''. About 8K members, only posts are auctions and only bids allowed in comments. Theres a template to use. Its pretty good for anything, but it has to be a good deal to begin with. Spend some time watching all the others to get a feel for how to do it
Other venues are Etsy, reddit, make a plant store facebook page. Post sale threads here, not a huge audience but growing more every day. Ebay is another
For the avg hobbyist that wants to capitalize on their valuable trimmings every few weeks, but doesnt necessarily want to make it a business, that auction group on facebook is a pretty good place to do it
Those are just some thoughts
