This sturdy, easy-to-use meter allows students to measure the intensity of sunlight in foot-candles (the term for units of light intensity, or illuminance) by aiming the photocells mounted on the top of the unit towards the light source. A scale on the meter provides a readout from 0 to 10. This versatile meter may also be used to test moisture, fertility, and alkalinity content in soil. No batteries are required - solar powered! Includeds a detailed insert on how to properly utilize the product.
The soil’s pH level will effect how well plants utilize the total nutrients available in the soil. These nutrients are the building blocks the plant requires for successful growth. Successful growth cannot be acheived with inadequate or improper light intensity. And even if these three key growing conditions are ideal, a garden will not thrive if over or under watered. Pick up one of these testers today to increase the fertility of your garden, and well as your growth success rate!
