more on my tunnel building
So I still have the 14 foot wide greenhouse film (in the package still) for a two bed wide low tunnel. Now that I buy EMT and bend with my foot I figured I could just take 2 and bend them into a U and make it a 14 foot half circle. It will leave 6 extra feet though. What is the best way to connect them? Being they will overlap say 4 feet and 2 feet in the ground can I just bind them together with duct tape so they overlap on the middle/top?
