WOW, this one has grown it's leaves much bigger in the course of HOURS! It's amazing to see a plant visibly grow not in days but hours. And the little fairy ring is cute! I don't think it's dangerous to the plants, AFAIK, most mushrooms are very specific in their feeding and if they are saprophytes they will only help convert the wood chips into usable nutrients, and won't attack living roots. Where's a tiny gnome when you need one? Or a teensy toad.

Oh, and these leaves look wider than what I have seen in past efforts. I think it may be more indica, which tells me the weed was grown by a pro, which is why it was so much better than what is commonly available here. (At decent prices anyway, I only paid 60/half for it.)
