Baby steps. Plant grasses and wildflowers first, then in a year or two, trees.

Drones FTL. Any given acre can be planted the same way much faster by an actual person or (the horror) simply scattering the seed balls from a real plane. Yes, it looks like it costs more that way, but unless you set up your drone ops right next to the acre you're seeding, how much of your 30 minute flight time is spent in transit, and how many 30 minute flights do you need to spend 1.5 hours actually seeding that acre? And if you are set up right next to that acre, a bag of seed balls and a planting stick can seed that acre in a lot less than an hour and a half. If you use a plane, you get more speed and carry more seed balls. They may not be planted 3" below the surface, but clay with fertilizers, hydro gels and pest deterrents ought to do pretty well just lying in a divot.
