You'd need access to a laboratory and chemicals to make LSD - it doesn't 'grow'. If you are meaning mushrooms, you'd need the mushroom spore but once you had that, they are pretty easy to grow. You'd probably be better off obtaining some Hawaiian Baby Woodrose seeds which are a natural source of LSD. but I've heard that they are pretty nasty to ingest and cause moderate to extreme nausea in a lot of cases.
