The Hi-Tunnel we use has roll-up sides. It's been through tremendous winds (50-60 mph sustained) and endured it. I think the roll-up sides improve ventilation, making it a worthwhile innovation.

Subject: more greenhouse clarifying questions!

Hi folks, this is nan again....forgive lack of knowledge, but what is IR (alison?)  and
 
Lynn - what are the 40 inch sidewalls that you roll up in summer (does this refer  to your greenhouse plastic that you can roll up so sides are open, but you still have plastic over the top....Is it tacked up with boards on the bottom end that then the plastic rolls aroudn?  and do you put shade cloth over the remaining top plastic for the summer usage)
 
If I go with the double plastic inflated with little fan system, per Alison's model, does this give me better wind resistance, or not relevant?  Can you then roll up the system in summer to have a completely open frame (i.e. no plastic at all, for summer vegetables, which here in Miss., unlike New England, get ALL THE HEAT THEY NEED OR WANT!)
Does this seasonal removal of plastic compromise the integrity of the double layer w/ air system?
Or maybe it is actually a good idea to leave plastic on top, with sides rolled up, and put shade cloth so that it will be COOLER than normal in the summer, or maybe cooler in late summer when I want to put in the cole crops in July (the recommended planting time here to harvest for fall sales)
 
YEEPS....I can see that some of this will just have to be trial and error.....sigh.....
 
 
Having come from Massachusetts, but now in Miss. ,I am wary of applying anything that is learned up north to the situation here (even though I love Eliot Coleman's books and such)
 
Another structural question:
If I build a greenhouse with roll up sides, will this leave me more vulnerable to winds that would then rip it all to pieces?
 
again, many thanks from nan and the goats
