Most of the new greenhouses I've visited recently seem to favor internal shade cloth. What are your experiences? How is this decision shaped by the transmission properties of polycarbonate?

Lisa,
All of our greenhouses have the shade cloth on the outside. We found here in the Midwest that in the hot summer months there was too much heat buildup from having the shade cloth inside. Having said that I only have experience with conventional black mesh cloth, but it makes sense to think if you are blocking light and heat it has to give it up to somewhere and that surface will be at the point of blocking, I learned the hard way that keeping the shade cloth secured is just a matter of good staking and good restraints.
Hope this helps a little,
