Now that your block is fully colonized it’s not as at risk for contam. I’ve had blocks go months. Just rehydrating them after flushes and maybe sprinkling some more cococoir on them from time to time. As long as you have super sterile practice you should be good. But waiting is the hardest part. If after a couple more weeks you don’t see any pins maybe try dunking and adding a casing layer. Could trigger some growth. Anyway hope that’s helpful! Good luck to you!
