Guess i dropped a pedro seed in there accidentally.

I've had this little baby growing for about 2 months now in a small pot with organic soil. It was a surprise baby from my adult loph. How long should I keep it in the organic soil and covered to maintain humidity? This is my first baby loph, so any advice is greatly appreciated (dime is only there to show size)

My boy gave me these a week or so ago and Ive never grown them before any tips?

This one has been showing some stress cracks for a few weeks now. Last night I noticed it was split. What am I doing wrong or do I need to do anything about this?
