geotextile? landscape fabric? the amazon link didn't work. mum's the word on the "patented" material used to make smart pots, apparently. i've heard of ecofelt. anyway, i want to make 48 200-gallon smart pots. need an affordable, bulk material. The manufactured 200-gallon pots are all too tall. i want to make one seven feet in diameter and a foot and a half high (7' x 18"). please, anyone, if you have undertaken large DIY smart pots (not 5-gals!) and succeeded, chime in! i need to find the cheapest bulk fabric that still breathes. anyone. weirdly hard to pin this down. $5/yard, by the way, is not cheap, not when making large pots like these. peace.
just found this:
