Hi All !! :thumbsup:
I am in the process of building a greenhouse. It will have 5 windows that measure 8.0 X 5.0 .
What I need to know is, what would be the best material to make Black-out curtains out of? I plan on supplementing natural light in the winter with about 1800 watts of light.
I am open to all suggestions.
Thanks!!
:hippy:
