Ideas for removable ends on Hoophouse ?

Our goal for the hoophouse going up this fall is to have almost 100% open ends all summer long.....

What is the best way to do this ?    

I originally though of LOTS of doors / windows....   but that's pretty complicated, they are all standing open = sticking out all summer long, and costly.

I am now thinking c channel and wiggle wire (the top would already be that for the roof anyway), along the bottom, around the door and around a fan opening... and (this is the question, how much framing and how much c-channel / wiggle wire is needed for the plastic ?  I see roof hoops from 4' spacing to 6' spacing..  should I put up smooth tubing vertical supports every 6' on the end walls, and have the c-channel / wiggle wire only top, bottom and around the door (and around one big fan for winter cooling), OR do I need one or two vertical's to have C-channel too ?

OR, is there a better / different way ?

The kit is coming with the end wall plastic only...   I seem mostly fixed end-walls using big washer nailers or tape over 2x4's vertical...    

all ideas appreciated.

Scissor doors would be my choice

Great idea to consider, one I had not run across before !

I g...gled images of them, and yes, they look pretty easy to construct and use!

Questions though: how do they tolerate wind? Some pictures show at least some framework behind the "doors", so if you only need airflow when open, and not people access, I could seem them working in wind.

Robert Marsh mentions both a people door and a fan opening. Would/could those both be on the same wall? If so, you could build a fixed panel containing both of those, then a 1/2 scissor on each side maybe?

Robert Marsh, could you give us some hints about the ecosystem you're in - snow/wind/risk factors?

River valley running E-W, zone 6, on the edge of tornado alley in SW Missouri. Most storms come from NW in winter, SW in summer, with the occasional severe one from the SE. Wind break to the West, hill with trees close by to the North. the Hoop house will run N-S (so open ends facing North and South), just to the East of the Western wind break.  Had 70MPH straight line winds last week just West of here, but did not go over 50 here. This is not too uncommon...

Snow is RARE to be over 2", but did have one 20" a couple decades ago.  Ice is common with 1/2" common and up to 2" once or so a decade.
