Modern Grower Sproutlet Self-Watering Microgreens Growing Kit, Reusable Trays (Pearl, 3-Pack) Review (2026)

Who this microgreens kit fits

This kit suits an apartment or balcony gardener who wants fresh microgreens on a kitchen counter without dealing with soil, trays of dirt, or daily watering reminders. The 3-Pack format is built around staggering plantings, so one tray can be freshly seeded while another is midway through growth and a third is ready to harvest, giving a rolling supply instead of one big batch followed by an empty counter. Modern Grower positions the Sproutlet system as a 10 day, seed to harvest process, which fits someone who wants a quick payoff rather than a longer term growing project. Anyone wanting large harvests for a household of regular salad eaters may find the compact tray size limiting compared with a bigger soil-based setup.

What is included and how the self-watering trays work

The kit includes 3 reusable growing trays, 3 matching clear domes, 15 compostable grow mats made from natural plant fibers, and 2 packets of organic microgreen seeds, so a new owner can start growing without sourcing seeds or mats separately first. This is worth noting because the self-watering design pulls moisture up through the mat as needed rather than requiring a daily top watering, which is the main reason Modern Grower calls the process low effort and mess free. The trays and domes are made from BPA-free plastic, and the humidity dome helps hold moisture in during the early germination days before it is removed for the rest of the grow cycle. Because the grow mats are compostable, they can go into a green waste or compost bin once a tray is harvested and cleared.

Living with the kit day to day

Daily care mostly means checking the water reservoir under the mat and topping it up as the self-watering system draws it down, rather than misting or hand watering the seeds directly. The pearl colored trays are sized to sit on a kitchen counter or windowsill without dominating the space, which matters for anyone growing indoors year round rather than seasonally outdoors. Because the kit is reusable aside from the grow mats and seeds, ongoing costs after the first purchase come down to replacement mats and seed packets rather than buying new trays each cycle. Following Modern Grower's included instructions for seed density and dome removal timing will have the biggest effect on how full and even each harvest turns out.

A correction on what is included, and how it compares

The retailer listing for this kit describes it as including reusable trays, organic seeds, and grow mats, which contradicts a common assumption that seeds are sold separately for microgreen kits like this one. Buyers should not need to source starter seeds before their first grow with this particular kit. Against soil-based microgreen trays, this self-watering system trades some of the yield density that soil can offer for a considerably tidier, no-mess process better suited to a kitchen counter than a balcony potting bench. Against single-tray microgreen kits, the 3-Pack format is the clearer advantage here, since it supports the staggered, rolling harvest that a one-tray kit cannot match.

Verdict and who might choose differently

For an indoor grower who wants a tidy, low-maintenance way to keep fresh microgreens coming every week or two, this Sproutlet 3-Pack backs up its top ranking with a genuinely complete self-watering setup that includes seeds and mats out of the box. Anyone who wants large volume harvests for regular cooking, or who would rather grow directly in soil for maximum yield per batch, will likely outgrow the compact tray size fairly quickly. Growers who mainly want to try microgreens once before committing further should also weigh whether a single tray starter kit fits their budget better than this 3 tray set.
