Re: [hoops?] PVC Length and Coffee Grounds

Square Foot Gardening List - http://www.flinet.com/~gallus/sqft.html

Does anyone have suggestions for covering the ends of a pvc tunnel? Is
their a better way to do it besides leaving a few feet of poly at each
end and gathering together into a bundle and burying/tying/nailing?
Also how to gain access to the plants inside for routine thinning,
feeding, etc.
