Just got a quick question about Oxygen generation - what's the best way to go about it? From the recipe page it sounds like there's emphasis on having the leaves be part of a tree (rather than shearing leaves off of an existing one and then placing them around the collector) Does the fan on the collector spin faster depending on efficiency? Is it actually possible to grow trees on the moon, or would I have to say create artificial ones by placing logs down and then leaves around it?
