Purple Cow CX-1 addresses the biological side of the soil health equation. Growers count on microbes to fix, cycle and/or solubilize minerals and other fertility inputs they apply. Adding biology along with minerals means uptake occurs more readily, and growers can reduce the amount of other fertility inputs they apply. Balanced minerals and diverse biology help the plant produce the phytonutrients' (sugars, proteins, amino acids and more), that contribute to plant health, beauty and nutrient density (taste). It also supports the plant's ability to withstand disease pressures with modes of action that include: competitive exclusion, production of natural antibiotics, and bio-sanitation.

General Indoor Use Recommendations
  1. Always jar test, liquefy any food source (fungal activator) or soluble input into CX-1 before adding a larger quantity of de-chlorinated water.
  2. Take into consideration that a broad spectrum liquid biological like CX-1 will make all other fertility inputs more available to plants. Always test a small area with reduced fertility inputs to make certain enhanced nutrient uptake is tolerable by your plants and dial back on existing fertility if necessary. 
  3. For drip irrigation, flush briefly with water after use. 
  4. For injection tanks, apply CX-1 within 6 hours.
  5. CX-1 is shelf stable for 6+ months and should be stored in a cool place out of direct sunlight.
  6. In a greenhouse setting, avoid applying foliar applications under direct sunlight.

    "Since starting to use CX-1 over lab cultured products, I've experienced more consistent germination rates with a shortened dormancy window, a very noticeable nutrient bioavailability uptake in soil applications as well as disease suppression properties from foliar applications. I grow in both controlled and natural environments and will never stop using this product." — ROBERT SOCHOR, BRIGHT FLOWER FARMS

    Frequently asked Questions

    What can/should I use with CX-1?

    • CX-1 should always be used with a food source (Fish, Molasses, or Purple Cow Activator) mixed just prior to application.
    • CX-1 can be used with soluble or micronized trace minerals and/or other biologically friendly fertility inputs.

    Can I burn my plants with CX-1?

    • While the beneficial biology in CX-1 will not overwhelm your plants, enhanced nutrient uptake may mean that fertility at your typical rates may be more than your plants require. Most growers begin by cutting back on their other fertility inputs by 15-25% and assess from there. 

    Can I use CX-1 in my fertigation system? 

    • CX-1 can be applied directly or indirectly as a soil drench or foliar application. Viable for all fertigation equipment (20 mesh screens), care should be taken to rinse out irrigation lines on a regular basis to avoid the build up of a bio-film. 

    What is the application rate of CX-1?

    • Apply 1 pint - 1 quart per 1000 square feet of greenhouse spray.
