When to choose it

Use a four-inch cover when the gap under a grow light or shelf is limited. The clear lid lets you see which trays have emerged, and the adjustable vents can be opened without taking the cover off.

Check the 21.6-by-11-inch cover perimeter against the rim of a tray you own. Compare the four-inch outside height with a taller dome if the insert protrudes above the base or you need room for upright cuttings.
