Expert Verdict — Reviewed by the SuperArbor Pro Desk

Place the cold frame where it receives maximum sunlight and orient the rooftop vent so you can easily open it on warm days to prevent heat buildup. Keep heavier pots toward the shelf supports and respect the 44 lb per-shelf limit. For larger plantings, use multiple units rather than overloading the two shelves.

Assemble the unit on level ground and secure the vent and doors before leaving it unattended in windy conditions.
