I have a little experience with knitted shade cloth. First of all I live in So. Cal. zone 9b where the summer temps can sometimes reach 106F. I thought long and hard as to what % I'd need for the summer and decided on 40%. In hindsight I think it would have been better to use 60% due to the fact that with 40% the inside temp will reach 110F when it is 85F outside and this is with the door and both vents open.
In side my g/h I have fragile seedlings and the higher temps are OK now but when the outside temp hits into the 100s i'll be forced to move many of my plants to the outside.
