Shades/windows that block direct sun but let light in?

[james mickelso]

Boston's sunlight is very weak right now and won't hurt catts or laelias but oncidiums and phals might need some protection. You can get spring loaded extendable curtain rods that just expand to the sides of your windows and then are held inplace by springs. You can also get sheer curtains that fit most windows. These are purchased at Wallmart or most large stores. That would be all you need. As for summer light, just add two together and that should be enough. A small fan would help cool any heat build up on the leaves. Pics please.
