The only thing I've heard that is worth growing is Abyss seeds, which gives you cells, which is then used to craft cores. I think the cores are used to craft gears, otherwise you can slot the cores directly into your gear. I still haven't used any gears, but I have a good 6 of them in my camp stash.Maybe it could be something cool if you were able to grow something from exotic seeds and then use the special cooking device for it.
