SC Greenhouse Growers Association Names Scholarship in Honor of Donald F. Looney, Sr.

The South Carolina Greenhouse Growers Association recently announced the naming of a scholarship in honor of Jāderloon® founder Donald F. Looney, Sr.  An excerpt from the announcement is below:

“Don’s dedication to the greenhouse industry was immeasurable.  His innovative ideas created equipment and supplies that have become standards in our industry. His generosity and willingness to share was known by all, and so many of our members have benefitted from his knowledge.

Don and Jāderloon® are known far beyond Irmo, Columbia, and South Carolina. We are so very proud to have known Don as a businessman, an innovator, and a friend.

Don was respected and beloved by the greenhouse industry and we are honored to be able to name a scholarship after him.  The first Donald F. Looney, Sr. memorial scholarship will be given to a Clemson University Horticulture student at the end of this year.”

Ark Encounter in Williamstown, KY Chooses The Greenhouse Company

Ark Encounter FloralsOver the last several years, Ark Encounter in Williamstown, Kentucky has purchased seven greenhouses from The Greenhouse Company.  Tim Schmidt, the Senior Director of Site Development and Horticulture at Ark Encounter, stated that they currently grow about 20,000 six-inch annuals yearly as well as several thousand tropicals for their own use and for use at their sister attraction, Creation Museum.  Schmidt anticipates an increase in these numbers as they continue to expand.  In addition to florals and plants for landscaping, they also use greenhouses from The Greenhouse Company to grow fodder and barley hydroponically for their zoo animals.

Tips to Avoid Spring Headaches and Product Losses

Exhaust Fan Belts:
• Re-adjust belt tension after 8 – 10 hours of operation.
• Check for proper belt tension by pushing on belt between blade pulley and motor pulley with index finger. Belt should move about ½ inch with 5 pounds of pressure.
• Keep replacement belts on hand.
• Check belts at beginning of cooling season and several times throughout year.
• Look for polished sides and cracked, dry, and/or brittle material.
• Replace belt if any signs of deterioration or if in use for several seasons.
• Clean fan blades and louvers as needed.
• Remove foreign material from inside fan housing.

• See installation manual for adjustment of drive motor limits
• Rack and pinions may be adjusted by loosening nuts on vent shoe where rack attaches to vent door
• Shift rack shoe left or right to improve alignment
• Check the alignment with the vent door open
• Clean the entire vent including the cover with soap and water
• Remove accumulated debris in the lower track of vent door

Carolina Cooler™:
• If float valve is unable to shut off, cut off water supply, disassemble and rinse float valve, reassemble and install
• If after above (if float valve still will not shut off), order a rebuild kit or new valve
• Rinse out reservoir and fill with clean water at the beginning of the season
• Do not leave in ground tanks empty
• Clean the filter as well and several times throughout the year
• Check the filter if flow seems restricted
• Check the header for clogs
• Rinse out the header at the beginning of the season – remove the plug opposite the pump and then run the pump to flush out foreign material
• Add chlorine bleach or any good algaecide to the reservoir on a regular basis to keep pads clean
• Maintain a pH between 5.5 and 8.5 in the reservoir
• Allow pads to dry completely each night by keeping the thermostat set above the overnight low temperature
• Use the gate valve to adjust the water flow so that the water sprays 12” into the air at the far end of the header from the pump

The following is a testimonial from Nancy Platt, teacher at James B Edwards Elementary:


“After purchasing and using a small greenhouse with our special needs students and ECO club throughout the 2015 school year, we were approached by interested parents and staff of James B Edwards Elementary School to discuss securing a larger greenhouse for use of the entire school.


Upon determining horticultural goals, Ms. Donaho suggested a particular Jāderloon® model that would meet the needs of the school.  Each stakeholder took a role, whether it was writing grants, hosting fundraisers, or meeting district compliance requirements.  Slowly the dream became a vision, and the vision became a reality.  The process took time and tenacity with leadership changing at the school and vested team members carrying on the mission despite this change.  No amount of bureaucracy could stop the JBE horticulture team! 


After raising the funds required and winning the support of new administration, the greenhouse was erected in July of 2018, some three years after the initial meeting.  Horticulture expert and JBE mom, Kim Crane, along with multiple community volunteers now conduct a horticulture enrichment program for all grade levels at James B.  This program includes the 5th Grade running their own nursery business and selling their plants at the School. 4th Grade (Non SAIL or gifted and talented) is experimenting with growing food from food scraps and a greenhouse cut flower garden. 4th Grade SAIL is growing milkweed and studying the migration of the monarch butterfly. They are also starting a seed business. 


3rd grade Non SAIL are studying pollinators and native plants. They are growing indigo to sell at the native plant society plant sale. 1st and 2nd graders are learning all aspects of horticulture and making their own growing mix. Kindergarten is working with Clemson to fill raised beds with veggies that support our Back Pack Buddies Program. 


Our green team is involved in a seeds to shore line program where we grow spartina grass and plant in the marsh on a field trip to the Bears Bluff National Fish Hatchery. Our students bag oyster shells to support new reefs off our coast. We are fortunate to receive many grants to support the Lowcountry Sustainability Program at James B. Edwards Elementary. 


Our new Greenhouse is beautiful and the Children LOVE spending time in it.”

The Greenhouse Company Loses One of It’s Founders.

Donald Franklin Looney, Sr.
November 14, 1944 – November 28, 2018

Donald Franklin Looney, Sr. of Irmo, S.C., our beloved father, brother, uncle, and friend, entered the triumphant glory of God on November 28, 2018. A memorial service celebrating Don’s life will be held at 2:00pm on December 8, 2018 at Union United Methodist Church, 7582 Woodrow St, Irmo, S. C.

Don, the son of the late Johnnie Walter Looney, Sr. and Sarah Nunamaker Looney, is survived by his sons, Donald, Jr. and Thomas Looney and their mother Judy Moore; two brothers, Johnnie W. Looney, Jr (Nancy Flowers) and Charles Looney (Helen Brabham); and by two sisters, Elizabeth (Beth) Looney Richardson (Gene) and Suzanne Looney Newell (William) and many nieces and nephews. He was predeceased by his youngest brother, Dennis C. Looney, Sr.

Don was born on November 14, 1944 and reared in Irmo, S.C. In 1963, Don entered Clemson College with his boyhood friend and cousin Danny Derrick. Within a few days, they met another freshman, Charlie Jager of Charleston. The three became fast friends, and combining their names, Jager, Derrick, and Looney, they formed the “Jaderloon” brotherhood that would last a lifetime. After graduating from Clemson in 1967 with an electrical engineering degree, Don served for four years and was a captain in the United States Air Force. He then joined South Carolina Electric and Gas Company as an electrical engineer, and, soon after, met the requirements to become a licensed professional engineer.

In the early 1970’s, Don and Danny saw a growing demand for greenhouses and related technologies. Seeing the opportunity and having an extraordinary entrepreneurial drive and optimism, Don resigned his position with SCE&G. With Danny, he co-founded a greenhouse engineering company that would become known worldwide for its innovative greenhouse technologies and services. In 1976, the company was incorporated as Jaderloon. Don’s numerous patented inventions demonstrated his ability to create simple, practical advancements in greenhouse technologies.

In addition to being the quintessential entrepreneur and businessman, Don was active in his community. He was a lifelong member of Union United Methodist Church. For 30 years, he served on Irmo’s planning commission and was an influential member of the task force that named Irmo’s Lake Murray Boulevard. Don served on BB&T bank’s advisory board for 15 years, was a member of Ruritan, and was an admiral in the Irmo Navy.

Despite Don’s passion for sports, business, engineering, and his community, his greatest love and achievement are not found in any of these endeavors. Don’s greatest love was his two sons, Don and Tom. His greatest achievement was being their loving father. He was very proud of his boys and had them with him at every opportunity. In Irmo, friends would regularly see Don with his sons in church, at restaurants, and in the gym. Don patiently taught them greenhouse job skills at Jaderloon. Outside Irmo, Don took his sons to his greenhouse work sites, to Atlanta Braves baseball games, and to Clemson football, basketball, and baseball games.

In lieu of flowers, the family asked that you donate to the Union United Methodist Church building fund.

How to Prepare Your Greenhouse for a Hurricane

Our Engineer compiled the following list of suggestions assuming the worst-case scenario of extremely high winds from Hurricanes. The extent of the preparations will depend on your location and will ultimately be a judgement call on your part.

Close roof and any other type of vents. Turn off fans and shutters. To reduce the chance of a fire starting, turn off the main breaker. Cutting plastic is a big judgment call. If the winds are high enough the plastic may come off with no damage to frame, but there is no way to know for sure. If the shade cloth is expensive, you may want to remove it since it is not attached as well as the plastic.

1. Close all venting equipment
2. Turn off power.
3. Turn off water.
4. Remove smaller objects from area that could blow into greenhouse.
5. Secure greenhouse doors.
6. Remove shade cloth or add more ropes to keep it in place.
7. If greenhouse has any exposed glass, cover with wood panels.
8. Tall heater vent pipe stacks should be removed if not properly braced.
9. Be sure brace cables are tight and secure.
10. Hanging basket plants should be placed on floor or removed.
11. Make sure inflation blower damper is wide open for maximum inflation in polyethylene.
12. Any outdoor motors can be covered with plastic because of extra heavy rains.
13. Heaters, HAF fans, electrical boxes can all be covered with plastic in case the cover blows off.

Please contact us if you have any questions or problems 800-258-7171.
