That is one of my Lotto-Fantisys, an Aquaponic Geo-dome green house/fish room
Has anyone ran the globe? Greenhouse would be awesome, but that globe pic seems misleading. I'm pretty sure salmon need a salty part of their lifecycle and get huge/need cold water and carnivorous food, same with trout.
Carrots and other root crops don't do good. In hydroton or gravel you end up with something that expanded into the free space, so would not be recognizable as the well formed roots were used to. Maybe in coco fiber or a less dense substrate.
