Why we tested the Mkono Windowsill Planter
Not every indoor herb growing approach needs to involve electronics. The Mkono 3-piece planter is exactly what it appears to be: three ceramic pots on a bamboo tray. We tested it because the majority of people who try windowsill herb growing have a simple question: does this work? The answer is conditional on the light situation, and we wanted to document that condition honestly rather than assuming it.
How we tested
We set up the Mkono planter with three herbs in a south-facing kitchen window that received approximately 5 hours of direct afternoon sun. We planted basil, chives, and parsley using the Espoma Organic Potting Mix and tracked germination, growth rate, and first harvest timing. We also placed a matched set of the same herb seedlings in a north-facing office window to document the light dependency. Testing followed our indoor herb garden methodology.
Performance: good pots, light is the variable
In the south-facing window, the Mkono planter performed well. Basil established from transplant to usable harvest size in 3 weeks, chives and parsley in 4 weeks. The ceramic pots maintained consistent moisture and the drainage holes cleared excess water cleanly into the bamboo tray, which showed no warping after two months of regular drainage.
In the north-facing window, the same herbs were still alive at 8 weeks but had produced minimal harvestable growth. Basil became leggy and pale within 3 weeks, stretching toward the minimal light available. Chives grew slowly but remained healthy enough to harvest a small amount. Parsley survived but did not thrive.
The bamboo tray is the quality surprise of the set. It is thicker than the photos suggest, with no visible flexing when holding three full pots of soil. After two months of regular water drainage, the tray showed no signs of mold, cracking, or delamination. Budget bamboo trays in this category often warp and mold within a season.
The ceramic quality is good for the price. The glaze is even, the drainage holes are the right size (neither so large that soil falls through nor so small that drainage is restricted), and the white color stayed bright through the test period.
Who should buy this
The Mkono windowsill planter is the right choice for cooks with genuine south-facing windows who want an attractive, low-tech herb setup that integrates into kitchen decor. At $25 it is the lowest-cost entry point for kitchen herb growing. For apartments without good direct sun, the investment in an AeroGarden or Click and Grow system that provides its own light is the practical alternative. This planter is a framework; its success depends entirely on what you bring to it in terms of light.

Should you buy the Mkono 3-Piece Windowsill Herb Planter?
The Mkono 3-piece planter set works well for what it is: attractive ceramic pots on a bamboo tray for windowsill herb growing. The drainage holes are properly sized, the ceramic quality is good for the price, and the bamboo tray catches runoff cleanly. The honest caveat is that soil herb growing on a windowsill is dependent entirely on available window light, which varies by season and apartment orientation.
Frequently asked questions
What kind of window is needed for this herb planter to work?+
South-facing windows with 4-6 hours of direct sun are best for most culinary herbs. East-facing windows with morning sun work for lower-light herbs like parsley and chives but may be insufficient for basil and thyme, which need more light. North-facing windows are not suitable for most herbs without supplemental grow lights.
Should I put seeds or established plants in these pots?+
Either works. Established herb transplants from a grocery store or nursery will produce harvestable herbs faster. Starting from seed takes 3-6 weeks to reach a usable size depending on the herb. If starting from seed, use a fine seed-starting mix, then transplant into a regular herb potting mix once seedlings are 2 inches tall.
How often do I need to water herbs in ceramic pots?+
Ceramic pots retain moisture slightly better than plastic because the thick walls do not allow evaporation from the sides. In a typical heated indoor environment, most herbs in 4-inch ceramic pots need watering every 3-5 days. Check by inserting your finger 1 inch into the soil. If it is dry at that depth, water thoroughly.
