Cheap tube steel, more like rolled tin, weak plastic tee connectors. This is my second unit I learned that it cant take Nevadas summer heat so this new unit will come down in the summer, also the wind will bend the frame so xtra hold downs. But in the fall,winter, spring and until the end of June it is great plants live and bloom great the temp is warmer inside. Money wise very good but modify it.
The year long test of this unit
