Big Rootz All Purpose Potting Soil Product Review

When it comes to the best cannabis nutrients for soil, Big Roots falls short. Although the product claims to be built by growers for growers, this potting mix doesn’t appear to stand out.

Their ingredient list, lists pre-washed coco-coir, peat moss, and compost as their base materials. Coco-coir and peat moss are both inert substances, which also lead to pH swings within the soil. If the only food source is compost, then it’s likely that you’ll need to supplement your cannabis plants during the flowering phase.

Furthermore, pests, such as fungus gnats, may find the perfect environment in Big Rootz’ soil bag. Through the humidity of the soil or due to the compost, various pests have been found within this soil mix.

Lastly, the price is double (or triple in some instances) that of competing products. Considering a bulk of the ingredients are technically inert, you’re paying for only a fraction of actual plant food.

If you’re looking for the best soil mix for cannabis, you’ll likely find it elsewhere.
