Mother Earth Subterra Root Booster 0-1-1 is a liquid plant supplement for transplants and starts. Young plants need strong root systems to reach their full potential as they grow. With a unique blend of kelp, brewers yeast, alfalfa meal and more, seedlings, cuttings and vegetative plants will have the foundation they need to flourish. By helping establish vibrant, vigorous root systems, Mother Earth Subterra Root Booster sets your plants up to seek out and soak up the nutrients they will need. Use with all types of plants, soils, potting mixes, and plant foods. This supplement is designed for use with a base fertilizer, like our Mother Earth LiquiCraft Grow and Mother Earth LiquiCraft Bloom two-part liquid fertilizer system.
