The Hydroponics 4-Way Test Kit offers tests for pH and three key nutrient factors: nitrogen, phosphorus and potassium.

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of microlife, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, WARD’S has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample. Comes with a dichotomous key and either the Working with Algae or the Working with Protozoa manual. Supplied in a single jar.

Contents: Amphidinium, Cyclotella and Thalassiosira.

Sarracenia purpurea var. Dicot. This plant’s unusual hollow, red-and-green pitcher-shaped leaves are used to trap insects for the plant’s food. The leaves hold water in which trapped insects drown and decompose; the leaves absorb the nutrients from the decomposed insects. It is native to acidic bogs in temperate regions, although some species are found in tropical areas. It prefers acidic conditions in terrariums and comes supplied in a pot with care instructions. Size: 4–6".

A compact multi stage system.
