Wicking Filters
 

I am building a greenhouse and I cant find a supplier for some wicking
filters that are about 3 foot x 2 foot x 6 inches wide with a honeycomb
pattern on the faces. I have seen them used for humidity control in orchid
houses with great results. the water flows down through it and the air
passes through it sideways. it appears to be made of paper .


thanks.
