Thanks Mitch1075!
I would treat those just like a Smart Pot, so no risk of over water with Coco, but with soil, yes, you could over in those.
Not sure if anyone mentioned it yet, but when you water, do it nice and slow, that way the water has a chance to soak ALL the soil, instead of just part of it, with the rest running off and leaving some roots dry.
Those fabric pot's are great for growing in though, and help give your roots what they crave, plenty of oxygen.
