SunBlaster LED Micro Growlight Garden - 21in - Black

Self-Watering Countertop Garden for Year-Round Herbs and Greens

Keeping a countertop herb or salad garden alive usually comes down to remembering to water it and finding a spot with enough light, and both are easy to let slip. SunBlaster's LED Micro Growlight Garden addresses both in one compact unit, pairing a built-in 6400K LED strip with a self-watering reservoir that feeds plants through capillary matting for about a week between refills.

At 21in x 8.5in x 5.25in, the Micro size is built for windowsills, countertops, and desks, giving apartment dwellers and office gardeners the same self-watering, lit growing system as SunBlaster's larger Growlight Garden in a smaller footprint.

Key Features & Benefits

• Built-in 6400K LED strip — positioned at a fixed height above the growing trays, so there's no separate light to mount or aim.
• Self-watering reservoir — capillary matting draws water up from the reservoir to the growing medium, reducing how often the unit needs refilling.
• Elevated inner platform — keeps containers above the water level so roots draw moisture through capillary action instead of sitting in standing water.
• 4 reusable seedling trays — included trays support succession planting, so a new batch of seedlings can start while an earlier one is still growing.
• Compact 21in footprint — sized for windowsills, countertops, and desks rather than a dedicated grow tent or shelf.

Who Should Use This

This garden fits apartment dwellers, home cooks, and office gardeners who want a low-maintenance way to grow herbs, salad greens, and microgreens indoors without dedicating grow-room space to it. It also works for early seed starting where a compact, self-contained, lit system is preferred over a larger tent setup.

Frequently Asked Questions

How does the self-watering reservoir work?

Capillary matting sits between the water reservoir and the growing trays, drawing water upward as the growing medium dries out. Refill the reservoir through its fill opening when the water level drops, typically every several days depending on plant size and room temperature.

Can I use liquid nutrients in the reservoir?

Yes, a diluted liquid nutrient solution can be used in place of plain water. Flush the system with plain water occasionally to prevent salt buildup in the growing medium and capillary mat.

How is the Micro different from SunBlaster's full-size Growlight Garden?

The Micro shares the same self-watering system and 6400K LED lighting as the full-size Growlight Garden, but in a smaller 21in footprint suited to windowsills and countertops. The full-size version offers more growing area for additional plants or larger containers.

Is the LED strip replaceable?

Yes. The built-in 12in SunBlaster 6400K LED strip can be replaced with a new SunBlaster strip of the same size once it reaches the end of its useful life.

What can I grow in this garden?

The compact trays and 6400K spectrum suit herbs, salad greens, microgreens, and small flowering house plants grown indoors year-round. The 21in footprint keeps the whole setup within reach of a single windowsill or countertop.
