I would say if the honeycomb did little to cool, created more humidity, and you are not using it, I would definitely try the screening. What about replacing with a powered louvre (shutter) if you are concerned about cold times in Florida?
Here's one company that makes good products, but if you go with this idea, shop around...

I've also seen, can't remember where, power shutters with rubber on the tip of each section so it seals better when closed.
I know HD Box fans are cheap, but they don't move as much air as a good greenhouse fan or two. Look for low hp/ high efficiency. I have two Hydrofarm ActiveAir wall mounted 3-speed oscillating fans, and I seldom have both of them on at the same time, and when I do, they are both on low. This winter, I kept 1 of them on low, and it took care of the whole greenhouse. I probably should have only bought one.
I forget where I bought them online, but here's a link to see the model I bought. I think I paid $39 a piece. Hydrofarm makes a number of different fans. One thing I like about mine is there are two long cords, so I don't have to climb up on something to set the speed and/or turn on/off the oscillation.
