Proven Solution for Greenhouse Growers


Controlled Environment Agriculture has exploded with demand for high grade sustainably grown produce year-round, and Coriphol meets those demands with increased yields, quality and profits for greenhouse growers.

Trials with Coriphol were conducted at The Farm at Brush Creek Ranch, a 5-star 30,000 acre resort ranch near Saratoga, Wyoming. They grow all the vegetables and herbs consumed by their guests and sold at their markets—in state-of-the-art greenhouse facilities without use of chemicals or synthetic fertilizers. That’s over 100,000 pounds grown organically and sustainably. Coriphol was integrated into their production methods to test if they could exceed their standards of excellence on all marks, raising their high bar on flavor, yield and marketability.

Hydroponic Lettuce Trials — Over 50% Yield Increase

From the Farm Team:

“We set out to determine whether Coriphol would have beneficial effects on plant growth and quality in our hydroponic program. Coriphol was injected into our hydroponic system at a rate of 1:1000 Coriphol along with our nutrient solution. The growth progress was monitored continuously and plant quality and over yield data were taken. After achieving full size, 16 heads were harvested from each treatment and weighed. Coriphol treatments astounded us! The average weight per head for the Control was 0.23 lbs. vs 0.36 lbs for Coriphol. That’s a 56% increase over the control!”

Container Soil Trials with 5 Carrot Varieties — 70% Yield Increase with 9.9% Higher Sugar

From the Farm Team:

“The purpose of this study was to determine whether Coriphol would have a beneficial effect on production yield and quality when integrated into our drip fertigation program, compared to our current organic practices. Five varieties of carrot, Cosmic Purple, Dragon Red, Napoli, Paris Market and Yellowstone were seeded at 24 seeds each, into raised beds. Each treatment was replicated in 3 beds.

The soil composition was 74% peat moss, 22% bark, 2.34% perlite, 1.62% vermiculite, 0.01% starter fertilizer, 0.14% lime and 0.10% silica.

Coriphol was injected into each bed by a Dosatron set to 1:100 dilution of a pre-diluted solution of 10 ml. Coriphol per liter of water for a delivered concentration of 0.1% (v/v) Coriphol in water.

Both carrot yield and sugar content increased significantly. Carrot yield increased 70% averaged across all varieties compared to the control group. Napoli tissue samples were analyzed for sugar content by an independent lab. Total sugar content increased 10% with a significant shift toward sucrose production.

“In addition to the analytical results, I had 5 chefs taste the different treatments and they were unanimous that the carrots amended with Coriphol were best in flavor. Quality is everything to our chefs, who agreed that these carrots were sweeter, without any bitter aftertaste, unlike some of the other experimental treatments. Best in taste and still a 70% increase in yield are pretty good results.”

Proven Solution for Strawberry Quality in Foliar Trials

“A few weeks after we implemented a weekly Coriphol spraying regimen, our strawberry plant leaves turned darker green and especially more shiny. We saw a small increase in berries production. More importantly for us on The Farm at Brush Creek, the berries became more red especially on the inside and feedback from our chef’s was that they were sweeter and tasted fuller than before we began using Coriphol.”
