Dave, Thanks for the great photos. The equipment we have is very similar.
Most people with a passion for gardening find this type of operation very interesting. I have to say, it is weird to work with the majority that look at it as just a job. They strive for the best looking healthy plants to leave the facility, but they are not home gardeners, so no passion or excitement about a great looking plant. I insist that our "office staff" take a walk everyday, with hopes that they will appreciate the beauty of plants.
