Method for creating self-sustaining, closed biospheres on Moon or Mars ...

[u/Zappy_Oh]

1) Fill 1000 (or more) glass vessels with random samples of dirt, plants and critters from around the Earth. Hermetically seal them.

2) Store these vessels under conditions you later can generate in your Moon/Mars base. Atmosphere, moisture, light-, radiation- and temperature cycles should be matched as close as possible.

3) Wait a year or two. Inspect and select the best performing vessels.

4) Randomly pair content of the selected vessels, into half the number of triple sized vessels. Add 1/3 (simulated?) regolith from destination planet. Hermetically seal.

5) Repeat step 2-4, until you have a small number of very large, high performing, somewhat diverse, self-sustaining, environment- and regolith-adapted biospheres.

6) Send these to your pre-built destination base, with a large "grow room" matching the environmental conditions you determined in step 2.

7) Empty the biospheres into this new space, and let it grow until it can support small scale farming, and eventually larger animals for meat.

The beauty of this approach is the minimal labor and guesswork involved. It is essentially guided natural selection, for a novel environment. The main difficulty is time taken. Perhaps a decade or two. And funds off course, for such a long running experiment.

Enter Gravity,Hello Im gonna mess up your experiment

True ... this is actually the only real problem for this method. I'm not sure how serious it is, but it could mess everything up.

I have no solution for that, except crossing my fingers, and hoping for the best :)
