Which Soil Blend should I use?
Whether you grow inside, outside or in greenhouses we have a soil blend to fit your needs. All our soil blends have a neutral pH with balanced micro and macro nutrients and a good primary cation exchange balance to insure optimal nutrient availability throughout the entire growing season. Biologic Systems soil blends are differentiated primarily by water holding capacity, aggregate, amount of organic material and nutrient content. Biologic Systems Gold Blend is high in organic material with 10% worm castings and 10% humus. Our Gold Blend also contains a significant amount of sphagnum peat moss and uses screened pumice for aeration giving it the greatest water holding capacity of our blends. Biologic Systems Silver Blend contains perlite, fir bark and coco coir in addition to peat moss which allow it to drain and dry more quickly. A custom 7-4-2 fertilizer is added to both the Gold and Silver blends. Whereas the Gold Blend has adequate nutrients for roughly 4 weeks before requiring additional fertilizer, the Silver Blend contains about 1-2 weeks’ worth of nutrients.

Why are your products registered organic through the CDFA and not certified OMRI?
All materials intended for use in organic systems must meet the requirements established by the USDA National Organic Program. In California, the CDFA fertilizer program was given legal authority to regulate Organic Input Materials (OIM) to insure NOP standards are enforced. Every organic product sold in California must pass a rigorous review process by the CDFA which includes an extensive examination of each ingredient used in the formulation of the final product: its origin, formulation, purpose and proof of efficacy.
The Organic Materials Review Institute or OMRI is a third-party, nonprofit organization that provides an independent review of products intended for organic use. While OMRI holds products to the same NOP standards that the OIM program does, it does not have the ability to seek criminal or civil prosecution and it is not accepted by the state of California. Where organic certification is concerned, the CDFA OIM program has the definitive say.

Do I need to pH my Biologic Systems nutrients?
Should I use liquid or dry fertilizers?
We have seen the best results from using both liquid and dry fertilizers according to the application rate and frequency outlined on our feeding charts. Dry fertilizers are most effective when applied to organically active soil which provides the ideal conditions for the fertilizer to slowly break down and release vital nutrients. Our concentrated liquid fertilizers are perfect for immediate absorption. See our feeding chart recommendations.
Brewed vs instant compost tea methods?
When working with tested inoculum-grade inputs that contain proven beneficial biology, a very potent “instant compost tea” can be achieved by simply liquifying and applying the products to plants immediately without allowing for brewing time.
After conducting numerous side-by-side trials comparing a brewed compost tea vs. an instant compost tea, we have concluded that the brewing process is not necessary and that the focus should be on using quality input materials such as Biologic Systems brand products.
Although some specific contexts still exist for aerobically brewing a compost tea in large agricultural contexts, we feel the professional hobby gardener or small-scale farmer can achieve maximum results without this added process.
