How is Big Rootz Soil Formulated?

Big Rootz is our all purpose soil blend and is considered a super soil; it has all the nutrients and inputs needed to allow the plant to maintain its healthiness throughout its vegetative life and into bloom. Our main blend was carefully designed with many years of beta testing, both indoor and out. Our soils always go through rigorous R&D prior to release.

Our top priority is to ensure any soil we design and produce is safe and clean. We have every batch tested for pesticide, heavy metals and GMO’s to ensure there are no inconsistencies in our product.

We also carefully select inputs from all over the world to ensure we meet our high quality standards. Pumice over perlite was an easy choice for an input in our blend. Perlite breaks down while losing its oxygen value, and it’s been proven to dangerously contaminate our local water sheds. Pumice, on the other hand acts as a mini condominium for microbial development and is much more resistant to breaking down. With proper care for the soil, Big Rootz can be used year after year making it not only the more cost effective option, but the more environmentally sustainable solution as well.

Three things are key when understanding your soil medium. Does it provide proper food, water, and oxygen to the plants. While most people find the first two simple enough, oxygen is one of the most important keys to good soil health and is often overlooked. In order for an annual plant to maximize its potential, it needs an abundance of oxygen which it intakes through the roots. Without proper aeration, your annuals will struggle to breath and never reach their full potential. Big Rootz allows for all three of those vital components to exist.

Soil King only selects the highest quality inputs for any mixed design. Our compost is sourced from only organic farms, and our worm casting provided by Terra Vesco, who are unrivaled at providing the highest quality worm castings and have the leading Verma Compost facility in the United States. Big Rootz also has a whole host of mycorrhizal spores which provide the base for a strong symbiotic relationship between the plant and the soil. These input ingredients allow for a large amount of biology count to activate the living soil along with an organic wetting agent to keep the optimal water levels consistent.

We take pride in putting on every bag that it was "Designed By Grower's For Grower's" and with decades of cultivation experience under our belts, we only strive for the best!
