You might be able to strap them to a straight board so they don't bow. Something like saran wrap with a wide profile (you can get 3" wide rolls of self adhesive wrap) will probably work well. Bungee straps would work but might bend the edges. |

in my set up I have NFTs. At first install, after the weight of plants and water they would bow and create an overflow situation. So I purchased 1 x1.5 inch pine boards, turned on side, screwed into the sides and used them as ribs for the NFT. I had old 5 inch black pipe that i cut 1 inch pieces and then halved. THose keep the NFT tubes in place. Don't mount evenly across. Like rain gutters, I allowed a degree or two of drop to ensure smooth water flow down to GBs.
