I've seen posts on making structure from 18qt wash tubs, concrete, pvc, boo, stakes etc... So I have all of the above. Do I need a tub for every one I build? Or do I pull the block out of the tub once its solid? If I pull the block out, does it just pull out easily? Or do I need to put something in the tub before I fill it? Also does it seem they land upright? I'm sure this has been asked before, I just dont want to search back. Thanks!
