CAES to Build A Multi-Disciplinary Greenhouse
Plant Growth Facilities will be adding approximately 8,000 square feet of greenhouse and support spaces tailored to agricultural and horticultural plant research at our Riverbend location. Construction began late-August '22. The facility will feature Wadsworth SEED environmental controllers, Adiabatic Cooling, Supplemental LED lighting, Automated-Irrigation Solenoids, Insect Exclusion, Sample Processing Spaces and more.

2426 Growth Chamber Expansion

Our newest growth chamber facility was finished in November 2021. The area features 12 Conviron chambers, 5 of which are reservable for use by CAES programs. You can view time slots available for research and current reservations at our greenhouse and growth chamber reservation page.

Graduation decor by PGF's Pam Lewis

Lewis has raised flowers and plants for the Graduate Recognition Ceremony for about 10 years now. All of the leftover plants are donated to nursing home and assisted living facilities in the Athens area.

Poinsettias are Lewis' favorite horticultural crop. In their natural environment, they flower in response to short day lengths. So preventing light drift in the winter months is paramount and achievable with the blackout tents we created.

Facility updates

Greenhouse M1 with the roof polycarbonate removed and the end wall replaced.


Greenhouse M1 thru M3 Polycarbonate Replacement

These greenhouses were built in 2008. Over time the polycarbonate has degraded from UV radiation. This impacts the quantity and spectral composition of the light transmitted through the polycarbonate panels to the plant leaves. CAES - Office of Teaching, CAES-Office of Research and Plant Growth Facilities are funding new paneling! Expected completion is early-June 2022.

Evaporative cooling pad update

Our facilities include 52 greenhouse compartments on three sites in Athens. Thirty-six percent of the compartments required almost 800 new cooling pads. Combining an order of this size allowed us to purchase with economies of scale. The savings were directed back into the cooling media by "double-dipping" many of the pads to extend their expected life from five years to an average of eight.

PGF's 1st Cool-Season Greenhouse


PGF's first cool-season greenhouse

Our facilities have expanded to include 600 square feet of cool-season greenhouse space to support Robin Buell's genomics research program. The greenhouse will be completed this May. These compartments will be a part of the larger multidisciplinary greenhouse expansion scheduled to begin construction in late-July 2022.

White Fly Grant


Whitefly grant

Thanks to a whitefly grant award, our entomology department's old greenhouse will be updated with supplemental lighting, area trench drains, insect-exclusion vestibules, new glazing and many other features. Following completion, the greenhouse will have five compartments all capable of BSL-2 certification.

Riverbend Soil Shed Update


Riverbend soil shed update

We have removed an unused raw material bunk in our Riverbend soil shed to increase the amount of mixing and sterilizing space and increase the amount of palletized media that we can have on hand.

Bartlett brings disease expertise to honey bee research, education
No line of research is too big or small for Lewis Bartlett — literally. From mammoth extinctions to the western honey bee (Apis mellifera), he’s published on a wide range of topics during and since university. But bees have had his attention since childhood.

Science communication is key to public acceptance, innovation
Genetic improvement, particularly improvements related to animal production, has been one of the most transformational agricultural advancements in our history. The breeding of healthier, more productive livestock has been achieved through genetic selection over the course of time, both through natural genetic selection and through increased use of artificial insemination.
