The plastic is not attached to the ground, so you just raise the side. According to Johnny's, the friction of the rope is sufficient to keep the plastic up, but in my experience on other farms, it is not. So I plan to use clamps to hold the plastic to the bow at the proper height.

That is one of the potential problem of raising the height of these tunnels. Side ventilation may not be sufficient, and too much warmth might accumulate at the top. I will have to think about this.


MAsteveIN, you have a really weird email quoting style! :)

Hello everyone,

I bought Johnny's "Quick Hoops" high tunnel bender. Their instruction
manual is really good, and I like their design. I am planning on
building two 100' tunnels this spring. I have two questions for those
who have built similar tunnels.

First, Johnny's tunnel are 7' high in the middle, which I find is a
little low for trellised crop. I would prefer something closer to 10'
high. I am thinking that, instead of cutting the 6' post in half, I
would use the full 6' length of the post, leaving 4' sticking out of
the
ground (instead of 1'). I This would make a kind of straight "side
wall" 4' high, on which the bows would rest. This would obviously cost
twice as much in post, but I think it is a fair trade off. Have someone
done something similar, and if yes, is the structure sound?

Secondly, how wide have you set the bows? The example in the manual as
a bow every 4'. I am planning on using three purlins (one in the
center, and two to attach the trellises to), so I am thinking the
structure will be quite solid indeed. I am thinking of having one every
6' instead. Would that be enough? My only worry is water accumulating
on the plastic above the purlins.

Beside, what was your experience? Any tips to share?

Thanks!
