Re: (ferns) hot-houses etc and keeping excessive heat out

Sorry, I figured that would have been obvious.

I use 73% on most fern greenhouses, and 50% outdoors on certain hardy ferns,
Cyrtomium, Dryopteris etc.

I've also found, if you really NEED to have plants in a greenhouse in the
heat of summer, cooling the actual greenhouse structure helps.  A drip hose
run on top of the greenhouse can cool it significantly.  Most days May-Sept
the greenhouse pipe gets hot enough you could burn your hand on it.
