WORM POWER WORM CASTINGS (or vermicompost) harnesses the power of tens of millions of earthworms in ideal and environmentally controlled conditions and fed a single and consistent feed, to produce the finest quality bio-stimulant available. The worm castings are then heated thermophilically to absolutely eliminate and pathogens and weed seeds. Worm Power is committed to delivering the highest quality vermicompost available anywhere to growers, golf course superintendent and landscapers. The science-based, research-supported process produces an environmentally safe organic bio-stimulant that improves the physical structure, chemical composition, and biological activity of soils and soilless medias.  

Worm Power is the largest process-controlled producer of worm-worked materials and castings (vermicompost) in the Western Hemisphere. All products are OMRI listed for use by certified organic producers and turf professionals.

The Benefits of Worm Power 

  • Single input source of compost for absolute product consistency.
  • The only worm casting heated thermophilically (manually) for absolutely no pathogens or weed seeds.¬† Most compost rely on internal composting heat, which does not get hot enough to eliminate many weed seeds.¬†¬†
  • Backed by university studies, including from Cornell University, to validate the process and efficacy of this uniquely produced product.
  • OMRI Listed for use by organic applicators to ensure quality and a verify it as an¬†organic product.¬†¬†

The Worm Power Difference

Worm Power Worm Castings Thermophilic ProcessingWorm Power is derived from only a single source of compost for the vermicomposting process, helping to ensure an end product that is consistent, uniform, and repeatable.

Thermophilic Composting & Monitoring:¬†The raw materials are composted indoors within controlled, engineered, aerated static piles.¬†This high temperature thermophilic composting step is completed prior to all vermicomposting. Compost batches are monitored daily to ensure that temperatures are maintained between 131¬į and¬†170¬įF for a minimum of three consecutive days, and that adequate aerobic and moisture conditions are met.
Vermicomposting Method: Engineered flow-through digesters are a critical component of the Worm Power vermicomposting process. These digesters, which host millions of earthworms, are located in environmentally controlled, enclosed buildings that actively maintain a regulated living environment for a healthy worm population.
Screening & Packaging: Finished vermicompost and worm casting products are screened to a variety of uniform particle sizes for ease of handling and consistent performance. Worm Power is screened, packaged, and stored indoors. Worm Power uses independent labs, including those at Cornell and Penn State Universities, for lab testing of feedstock, feedstock components, and the finished Worm Power vermicompost.

Worm Power is Backed by University Research

Cornell University has been studying the properties and efficacy of Worm Power for more than six years. Findings from these studies include evidence that the use of Worm Power enhances plant growth. Experiments evaluating multiple organic media components in greenhouse seedling production have demonstrated that mixes containing Worm Power vermicompost produce the strongest, most vigorous plants. Additionally, researchers note that vermicompost can successfully be used as a sole nutrient source for vegetable and flower plug production.

      Free Shipping Policy:
      For items with free shipping, we have the right to choose the carrier, either the US Postal Service or UPS.  Please e-mail us if you require a PO Box only or other shipping requirements.  If one carrier is required and it is not the most cost-effective means, we reserve the right to charge additional shipping fees.  

      Return Policy:
      Please email us at prior to making any returns so we know how to credit and return product payments.  We inspect all returns prior to making any refunds; refunds are only made after product is returned in good condition.  Products may not be returned if the seal has been broken.  Shipping charges are not refundable.

      Credit Card and PayPal Claims Filed First or Review Extortion:
      At Green Earth Ag & Turf LLC, we pride ourselves on excellent customer and technical service.  When issues do arise, often due to carriers such as UPS or the Post Office, we respond and work out the problems to the best of our abilities. Our reviews show our extensive service record.  Please contact us via e-mail or telephone first to see if the problem can work out quickly and fully through our extensive troubleshooting experience and highly rated customer service department.

      PayPal and Credit Card Claims Filed Before Contact: If a PayPal or credit card claim is filed before first contacting us directly and attempting to resolve it, we can not help out any further until the claim is fully processed, which can often take weeks or months.  If we are contacted before a claim we can often resolve issues the same day or very quickly.  However, once a claim is filed we must follow the policies and processes of the merchant, and this will very much slow down the resolution process and ultimately your resolution and compensation.  We reserve the right to appeal any unfounded claims, especially those not initially attempted to be resolved with us directly, and it is our policy to do so.  

      Review Threats: Our policy is that we will not respond when review threats are the first contact; such as when a threat of a bad review if a full refund is not sent is the manner in which we are approached. This then becomes a legal issue and may be referred to our legal counsel.  We also reserve the right to forward the threatening e-mail to the proper review agencies and state or federal authorities, and it is our policy to do so.
