Oh sure, next you'll tell me you rubbed it with unicorn tears and it came out perfect too lol. But for real, the 165 mark is just a number people started throwing around because that's when the stall usually hits. The paper lets some steam escape while foil traps everything, so you get better bark but it can slow you down a bit. If yours came out great on a 14 pounder, that's not luck, that's just how paper works when you nail the timing.

What was the humidity like on that windowsill when the moss ones turned? I only ask because I've had the total opposite thing happen, my moss tray dries out way faster than my gritty tray so rot has never been an issue for me, but my place stays pretty dry in winter. The sandy pumice mix sounds solid for wick watering though, do you bottom water or soak from the top with that combo? I've been wanting to switch a few of mine over but I'm scared they'll dry out too fast under a south window.
