Only when I water, it’ll occasionally come out the sides if I go too fast. I usually water every other day but I move them around every day. If any feel light I’ll give them half the usual to hold them over. 3 days seems to be too long between, they dry out too fast. Idk how they do outside, I’ve only used them in the tents.

They do stay rather dry around the edges. I’ve been using happy frog soil exclusively so far. It kinda shrinks up towards the end, sometimes leaving a little space between the soil and fabric. After harvest when I break it up there are 3 very distinct root layers. The top is dense, dry and about 3 inches thick. The middle is much looser, moist and 4 inches. The bottom is dense, dryer than the middle and 3 inches. The very bottom of that one is usually very dry and holds its form when I dump it. Almost like a thick Frisbee of dead root tips. So there’s a bunch of info you didn’t ask for. 😂
