Give your plants the best start in life with Baby Big Rootz® by The Soil King. This all-purpose potting soil is the product of Patrick King, owner of the Soil King Garden Center, and is designed and produced for growers by growers.

Baby Big Rootz® is carefully formulated with half the fertilizer concentration of Big Rootz®, the best-selling formula known for supporting your plants' growth and development. This potting soil is designed to support strong seed germination, boost root growth, and give your plants the foundation they need to thrive.

This soil works great in greenhouses, indoors, outdoors, and when mixed with other soils. With the perfect addition of amendments, the mix is microbe-friendly and is pH-adjusted for seed cracking and soft clone routes.

Just like Big Rootz®, Baby Big Rootz® undergoes intense testing before being released. The soil undergoes rigorous quality assurance evaluations, including sourcing natural and organic materials. In fact, Baby Rootz® is the only germination soil tested for pesticides, heavy metals, and GMOs on the market.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
