Started it in the tiniest cup. I actually thought I killed it for a day. But then it came back. I'm going to throw it in this tiny seed starter cup and then put it in the elephant when it's bigger. The elephant is 60% ocean Forest and 40% pro mix. I'm trying to not burn the sprout. Transplanting is going to be something I do like I'm doing surgery. I hear that autos are hard to transplant but I've never grown an auto before. Wish me luck.
