quality humidity trays in white has been impossible - until now!
you're growing with white outer pots, or under lights, black or brown
humidity trays just don't look right. We now have white
humidity trays that measure 22" x 11" x 2" deep. A white plastic grid
sits on 1 1/2" legs, creating a reservoir in the tray that holds over 1
gallon of water.
add a drop or two of household bleach to the water in the
trays and eliminate mold and algae altogether!
