I have used a Dosatron Injector for about 4 years. It works great and I have never had a problem with it. I have two sons who both have commercial greenhouses, no orchids, they both use Dosatron and feel they are the best brand they have used, giving them no problems. Google Dosatron for info on how it works.
I don't have a greenhouse, I grow my orchids in my home. I was able to install it by myself. It was very simple to do. If you wish, I can send you a picture of my set-up which is attached to a sink with only a splitter to switch to plain water for regular usage.
