Black Form Trays

I live in zone 7 in AZ. I left these sitting in the sun for a week. Went to use them and half of them were melted on the side exposed to sunlight and became so warped, they are unusable. I have several of these types of pots from other suppliers sitting in the sun all year long with out a problem. They should be labeled for indoor use only.

Really like these trays!

These trays will really help me stay organized for the spring growing season!! Everything shipped and arrived as promised.
