I have a bunch of interspersed free space around the yard where I'd like to put taters and maybe termaters in grow bags. From the Amazon description, most of the grow bags just seem to be Tyvek, but they're asking like five ducats a pop for them. I know Tyvek is cheaper than that.
Also, before somebody tells me to just make raised beds with scrap lumber, I have plenty of those. I want something temporary and moveable because I might need to follow (or avoid) the sun in a few spots.
Do any of you use grow bags and do you have a cheap source? Seems like they shouldn't cost more than $1-$2 per.
