I see in a couple of the pictures on the site that the bed seems to be lined with what looks like landcape-grade plastic. I am guessing this is to help protect the wood frame from moisture. My question is this: Is the plastic just on the inside walls of the frame or is it also on the bottom? Also, what is the Farmbot creators opinion of doing this?
Actually, the second part of the question is silly. Of course you would not line the bottom… Drainage… Doh!
