Luster Leaf Rapitest Soil Test Kit

The Luster Leaf Rapitest Soil Test Kit has been such a helpful tool for our garden! It’s easy to use and provides quick, clear results for pH, nitrogen, phosphorus, and potassium levels. The color-coded system makes interpreting the results simple, even for beginners. I really appreciate how this kit helps take the guesswork out of gardening. We’ve been able to adjust our soil based on the readings, and our plants are healthier and more vibrant because of it. It’s also a fun and educational tool for kids who want to learn more about how things grow. Whether you’re a seasoned gardener or just starting out, this kit is a great value and a must-have for anyone serious about plant care!

We live in Hawaii and the soil is a bit difficult to manage. As easily as everything seems to grow, we never thought we'd have soil issues. However when many of our fruit trees struggled, we bought this kit to analyze the soil. We found issues and once we amended the soil to address them, our trees were much happier and healthy. Never thought I'd have to be a soil scientist, but this kit made it easy and it worked well.

Works okay and was pretty accurate. Could use some redesign for easier use. The bottles tip very easily, so tend to spill as you’re adding in the powder from the capsules. Many of the reviews rating this poor failed to follow the directions which is clearly evidenced by the water level not being to the test line. The Ph rating was a bit hard to read.

Does the job, just follow the instructions. Do it right and see the results.

Very easy to use and read. Instructions are clear. However, the nitrogen test did not work. It read that there was no nitrogen in the soil, even my enriched garden soil that contains nitrogen. I also tried it on my nitrogen fertilizer and that read as no nitrogen. I am unfortunately past the return window, but at least i can use the other tests.

Worked as needed

Dont waste your money. Followed instructions, watched videos on they site. The colors that show up in the test vile aren't distinguishable enough to tell where they fall on the color scale. I threw the whole kit in the trash

A lot of the negative reviews are from the people who obviously didn’t read the directions. You mix your soil with water, wait 24 hours for it to settle, then test the clear water on top of the mix. Works great!!

Worked well. A bit of work involved but great if your garden sucks and you can’t figure out why. I sort of already knew why my garden was awful but the confirmation was nice.

Good
