Excellent way to block windows in grow area :
Buy 8'x 4' x1" construction styrafoam, ($23.00 , appx well worth the price for long term.)
1 Large can flat black durable spray paint
Cut window pieces to size, be sure to remove protective plastic film that protects most styrafoam sheets before painting.
Spray one side, when it drys use it as a window plug. Its advisable to glue a small piece in center or corners to help you remove the plug if you wanted to get some ventilation, i.e. easy in, easy out removal system.
I use this myself, if properly cut zero light escapes at night, perfect for budding.
