Hi- just purchased first AGP — so excited, but realize now it is an adventure. So, it is a Bestway 21’ x 48”- and we are prepping ground and investigating here best base on soil- and foam board seemed straight forward, but now I read no wrap… can I get feedback info if this is good or not - what harm it will be to go ahead and use it .. just need to understand it all better.. picture attached… thank you!!!
