These things hold a LOT of soil so make sure you are prepared. I assembled it in my garage while it was cold and raining outside. I then just carried it out and placed it in my deer enclosure. I then filled the thing with soil from a local supplier (13 wheelbarrows full). I waited about 2 months and then planted my seed mats from a local seed supplier (Territorial). Everything is just starting to come up now and I am super stoked!
