Flora Micro (NPK: 5-0-1) is the foundation of the "Building-Block" nutrient system. Flora Micro provides the nitrogen, potassium, calcium and trace elements necessary for superior plant health. Use the Flora Micro Hardwater version if your tap water is over 200 ppm (or contains Calcium above 70 ppm). If your water contains 30 to 50 ppm Calcium, you can mix the standard Flora Micro with Flora Micro Hardwater to create a perfect Micro blend for your plants.

Flora Bloom (NPK: 0-5-4) stimulates the flowering and fruiting development of your plants while enhancing flavor, aroma and essential oils. Flora Bloom provides high phosphorous, potassium, magnesium and sulfur.
