Sealing wood framed raised boxes?
I'm planning on building several raised beds for my SFG and "believe" they will be made of 2x8x? lumber. Not sure what exactly we'll be using yet (pine, cedar??). Anyway, I was curious, if I could seal the interior of the frames with something, or if that is not recommended due to vegatables growing in the beds. I know I can seal the exterior of the boxes, but was curious what the thoughts were on sealing the interior!
Thanks in advance! This forum has been extremely helpful to me!
