Beautiful plant. It's good to read someone who can speak about starting in cups with some experience. For me, once has sprouted in towels it's into the final dirt. I may have to change my approach.
Your photos are excellent. They alone are worth the visit.
Congrats on finding nanners early, and hope you let the Breeder know, they really need to address this issue. I don't think i recall that your grows have had this problem before. So I don't believe it was a light leak. Great work on your grow.
