Gro Terra 20-20-20 One part Mix Custom buffered for Organic soil and soiless mixes use for Vegetative Growth. SuperNatural Brand Powder Nutrients Supernatural Brand Powder Nutrients are a revolutionary one part nutrient system. They contain pharmaceutical grade B-1 (Thiamine Hydrochloride), and the highest quality source salts and minerals. These powders are more like dust in their consistency as they are turbo milled to homogenize and blend. They are fast dissolving in room temperature water and are treated with a dye so you know when there is nutrient present. These powders are pH Smart and will buffer your water to the correct pH for maximum absorbtion of nutrient. The powders are buffered differently for hydroponic or soil and soilless based growth systems. The soil and soilless mix called “Terra” are buffered slightly less and have a higher salt and mineral content than the “Aqua” which are designed specifically for hydroponics. Superboost is designed for either soilless or hydroponics and will help boost the phosphorus level greatly to help invigorate flowering and fruiting.
