It's a science experiment to grow plants on life support, everyone interested should try it, but it's not how we'll feed the world. The energy, maintenance and expertise costs will remain not worth it until life support is the only way left to grow plants.
We're still far from that, and, growing plants and trees in the ground will nudge the chance of worsening climate further away.
@harshad a lot of modern intensive agriculture is essentially hydroponics in the soil as there’s so little life left in the soil it needs a constant supply of artificial nutrients to function
