Sun System® Pro Sun™ LEC® 315 Commercial Fixtures

Combining the cutting edge Light Emitting Ceramic® brand technology with the Sun System® Etelligent™ controllability options (controller sold separately)
State-of-the-art 95% reflective German aluminum optic offers unparalleled output, reflectivity, and diffusion. The 315 LEC®/CMH lamp (sold separately) creates an amazing full-color light spectrum out of next-generation ceramic lamps. Higher amounts of beneficial UV and far-red spectrums increase the lamp’s growth power to the plants. The ballast is housed in thermally optimized, non-fan cooled aluminum that is ideal for commercial environments. This highly efficient electronic ballast designed specifically to drive LEC®/CMH lamps operates at a 160 Hz low frequency, square wave. Internal ballast programming will also protect the unit in an instance of open-circuit, short-circuit, over/under voltage or high-temperature exposure.
Sun System® Pro Sun™ LEC® 315 features an internal built-in circuit breaker. This unit is dimmable and can operate a LEC® lamp anywhere from 50% to 100% (10% increments). Low current, staggered ignition delay feature eliminates circuit inrush overload and protects lamp for increased lumen maintenance. The compact commercial design minimizes natural sunlight blockage in a greenhouse setting. Power cord or plug configuration varies by fixture voltage. Eye bolts included. Lamp purchased separately.

Lost Coast Plant Therapy

Protect your valuable crops from damaging pests, mold, and mildew with Lost Coast Plant Therapy. This non-toxic solution kills bugs on contact without using poison. Designed to suffocate and dehydrate on contact, the active ingredients in the spray adhere to the target insect, egg case or larvae, causing disruption of respiration and digestion within the pest.  The unique formula does not stress the plant and will not damage flowers, fruits or vegetables as long as it is applied under proper lighting and low heat conditions.
Lost Coat Plant Therapy has been laboratory tested by CW Analytical (among others) and found to leave no residue; this means it is safe for your soil, food and ornamental plants, pets and people. With proper application, the product can even be used on the day of harvest.

Grotek: Black Pearl

Soil Supercharger
Grotek™ was the first to bring engineered charcoal to our industry in 2009 as a means to improve soil quality, plant growth, and to stimulate soil biology. Black Pearl™ is more than just high-quality charcoal. It is super mineralized with plant and mineral derived inputs like volcanic and sedimentary rock dust, natural chelates, and kelp extract. The harmony between ingredients provides a dramatic boost to crops when added to any nutrient program. Remember that not all charcoal is the same. Grotek uses virgin wood fiber from sustainably managed forests, charred in an engineered pyrolysis process. It is considered a Class 1 product by the IBI standards with a surface area over 700m2/g.

Grotek: Synergy

Symbiotic Success
The variety of mycorrhizae found in Synergyis particularly effective in intensive agriculture when using fertilizers. Not all Mycorrhizae have constant positive results with crops. This is due to a lack of colonization, which can be impacted by the use of any fertilizer. This particular strain adapts to and tolerates saline (high EC) environments found in intensive agriculture far better than glomus intraradices and glomus mosseae. Under these conditions, Synergy™ shines with rapid colonization and improved impact on plants and soil structures.
