Rainbow Garden R687 Mini Greenhouse Review: Extend Your Growing Season Early

Four Tiers of Early-Season Advantage

The Rainbow Garden R687 is a 4-tier mini greenhouse that lets you start planting weeks before the last frost. Don't let "mini" fool you—it holds plenty of seed trays and gives your garden a serious head start.

Light Management

Lower shelves get ample sun; the top shelf can scorch in full sun. Provide light shade or position away from intense midday rays.

Ventilation and Heat

Built-in vents release excess moisture and heat. On unusually hot days, unzip the cover further. It's not a set-and-forget system—monitor and adjust.

Assembly and Stability

Sets up in ~15 minutes; instructions are clear but barely needed. Very lightweight—a plus for moving, a minus in wind. Best on a sheltered porch or indoors by a window. If outdoors, weigh down the base (rock-filled pots) and tie to a fixed object.

For an affordable, portable way to jump-start your season, the R687 delivers real value.
