If I build a hoop house about 18 ft by 48 ft and install raised beds in it,
Would heavy duty rebar be able to hold the side of the raised beds in place
?

I am thinking of beds being 10 to 11 inches high and it would be easy to
drive 5/8 rebar into the ground about every 4 feet to keep the sides up.

Also pressure treated wood would not pose a problem would it.?

any feed back would be very helpful I want to get the house as close to
right as possible the first time.
