I ordered some ....not sure if it was from this place you mentioned. I didn't check it right away... ....and it had spots where it would NOT hold water.
The material is a product called Duraskrim. I use the 20 mil stuff.
It's 'best' to use both...have your water go to the media beds first, to filter out the solids, then to the rafts.Originally Posted by ArtfulDodger
The rafts are great for lettuces, ect. The media is great for bigger stuff, like peppers and tomatoes.
