What do we think of these for torts that dont need closed chambers. They are cheap and easy to make. you can also make lids for them that can hold your lights each grid is 1FT X 1FT and you can make them as big as you want. the insert on the inside is Chloroplast which is a Plastic sheet with the same construction as cardboard with two flat sides and the spaced inside. Just wondering what everyone thinks about them as i am seeing them more and more. you also have the option to make the walls taller.
