LetPot Seed Starter Tray review

REVIEW – Gone are the days of my wife saying that she is not a natural at gardening. She has been so successful at it that we have not purchased Greens for our household in years. Last year, I noticed that she mwntioned setting seeds and seedlings a whole lot at the beginning of her planting season, so to me it was a foregone conclusion that this LetPot Seed Starter Tray would be a perfect fit for her.

The LetPot Seed Starter Tray features a compact, rectangular construction made from sturdy ABS plastic designed for long-term indoor use. The tray sits atop an integrated heating base and includes an adjustable full-spectrum LED grow light mounted on a slim, vertical stand, allowing users to customize light height and intensity for optimal seedling growth. There is a transparent moisture dome lid that helps maintain humidity during germination. There are front-facing touch controls on the base of the front, a designated port for the EC probe, and a bottom watering tray. The design allows for starting up to 40 seedlings at once.

Setup

The LetPot Seed Starter Tray is easy to set up and get started. The steps simply involve placing soil in the pods, adding seeds, connecting the lamp, placing the seed tray on the mat, and installing the water tester. My wife has much experience with gardening, and uses a type of Rockwool instead of soil. She has had much success with this. Here are photos of her process. You will also notice that she labeled each section according to the type of seed she set.

Performance

The LetPot Seed Starter Tray requires nothing but a simple setup, and in return provides solid performance and smart automation. Assembly is quick and intuitive. The instruction sheet is clear and easy to follow, and the sleek, sturdy, and compact design allows it to fit easily on a countertop or in any small indoor space you can find. Key features include the integrated heating base, adjustable full-spectrum LED light, and EC probe for nutrient monitoring. The simple design creates perfect conditions for seed germination and strong seedling growth. The companion app features a simple and clean interface and allows for the much-desired remote access to status and settings that customers would expect. The ease of use also makes the device less intimidating for those trying their hands at gardening/plant growing for the first time. The system maintains consistent humidity and temperature, which results in high germination rates even with a variety of challenging seeds.

For our testing, my wife successfully planted Iceberg Lettuce, Red Russian Kale, Early Jersey Cabbage, Black Magic Kale, Butter Crunch Lettuce, Swiss Chard, Pirat Lettuce, and Romaine Lettuce.

Overall, the LetPot Seed Starter Tray stands out as a reliable, efficient, and user-friendly solution for indoor seed starting.

What I like about the LetPot Seed Starter Tray

• Both soil and Rockwool work well

What needs to be improved?
