	Raypak Boilers Prove to be a Reliable Alternative Bluebird Nursery, in Clarkson, Nebraska had a big problem. A new greenhouse was built for propagation and it was equipped with all the latest technology. Mobile tray benches were selected to reduce labor, a computer control system was applied to make the environment more consistent, and a multi-zone hot water heating system was installed to deliver bottom heat and save heating fuel.	Bluebird Nursery

	"There is a significant difference in the performance of the Lennox unit compared to our old brand. Not only are they quieter and less expensive to run and maintain, but they look a lot better too; and in the plant business 'looks count'."	Donahue’s Greenhouse
	"I’m so glad you talked me into going with the high efficiency Munchkin boiler. It is so quiet, I can hardly hear it running, and it’s saving me money on fuel. The pre-fabricated boiler piping package is a must for any grower, as it saved me time and money. The pre-fab boiler loop was a snap and it looks professionally installed."	Greendorr Greenhouses
	"Lennox is the most reliable thing out there. Once you get them installed and the voltage right, there’s nothing else like a Lennox."	Henry’s Plant Farm
	"TrueLeaf Technologies proved to us throughout the sales process that they truly understood the environmental control issues we were having. After they were awarded the project, it became very evident that we had gone with the right company and the right controls technology."	Metrolina Greenhouses

	"The TrueLeaf Benchwarmer heating system allows me to produce a variety of plants in one greenhouse, it gives me the ability to regulate the heat and it saves on fuel."	M.R. Dickinson & Son
	"In each case the difference in plant growth, root structure, and overall healthy look of the plants was noticeable and measurable."	Possibility Place Nursery
	"We like to do a lot of things ourselves, but we also know when to take advantage of the knowledge and experience that a company such as TrueLeaf can provide."	Schroeder Greenhouses
	"The project was expensive but the system is efficient and effective. Perhaps more importantly, it is reliable so we are able to get our job done. There are as much savings in intangibles as in other hard dollar fuel savings." Ed’s grade for the project was straightforward as usual: 1.The results are good, and 2. TrueLeaf met all of their commitments and representations.	Woodbridge Gardens
	"We really appreciate the fill and drain system of TrueLeaf floors with the large holes and drain pipes because they are not as easily clogged by the many leaves from the Azaleas." Tom notes that he would like to try the TrueLeaf flow through floor fill and drain option on his next expansion to more easily flush those leaves out of the pipes.	Woodburn Nursery and Azalea, Inc.
	"About 10 years ago I discovered the BioTherm MicroClimate bench heat from TrueLeaf and today that same system is providing all the benefits that I expected from it."	The Growing Place

	"Lennox heaters and TrueLeaf have performed as advertised and that’s not usually the case anymore." Late one night, while installing a Lennox unit heater, Oscar had a problem. He picked up the phone and called TrueLeaf’s toll free number. Rob Longaker, one of our technical service staff, walked him through the rest of the installation.	Hilltop Farms
