We do not carry hemp or hemp-derived products. We are a dedicated testing lab.
Welcome to Devils Lettuce Test Labs, your go-to destination for precise soil testing. Specializing in the analysis of nitrates, potassium, phosphorus, sodium, and calcium, our lab provides accurate results to support your agricultural or environmental needs.
Soil testing is essential for understanding the nutrient profile of your soil. It aids in optimizing plant growth, diagnosing soil problems, and preventing overuse of fertilizers. Our focus on key nutrients - nitrates, potassium, phosphorus, sodium, and calcium - ensures a comprehensive analysis crucial for soil health and productivity.
Our Horiba LaquaTwin meters provide quick and accurate testing for soil and water, using advanced ion-selective electrode (ISE) technology. With a compact design and flat sensor, they measure key nutrients like nitrate (NO3-), potassium (K+), and calcium (Ca2+) directly from small samples—requiring just 0.1 mL of liquid or a moist soil sample.
Spread each separate pot sample and/or the mixed garden plot sample on clean surfaces to air dry, avoiding direct sunlight or artificial heat.
