I would post a link to my blog if you want the read the long story. Is that allowed?
Hermes, you can post the link to your blog in this topic if you wish, or you can post it in your profile or your signature line where it will always be visible in all of your posts. Several other members do have links to their blogs and websites in their profiles.
You don't say what part of BC you're in but if you're close to the lower mainland and Vancouver you might want to get in contact with these folks, http://www.gaiagarden.ca/
their dispensary is on West Broadway near McDonald Street in Vancouver. Very helpful folks if you have questions to ask first hand about processing herbs and they might let you peek through the door at the back room where they process and package their herb products so you can see what kinds of equipment they use. The back room is actually open and viewable from the front and it looked very efficient. I purchased a big bag of beautiful, fluffy, clean mullein leaf there last week and the gentleman who assisted me was quite helpful and knowledgeable with his advice.
Also, he was polite and patient and not abrupt with me during our converstation, which was very much appreciated and reciprocated. I mention that because I've noticed you have had a tendency to be somewhat impatient and abrupt in your responses with people here on the board a couple of times. Just saying .... you'll attract more honeybees with nectar than you will with vinegar, if you get my drift.
If you look at their website, along the side you will find several different informative links and articles - like this just for example:

Personally, if I was just beginning at doing tinctures I would not start out working with so much bulk and volume of product as you are doing until I really got the hang of all that is entailed with tincturing and other methods of processing herbs. I think it is better to start small and simple so you can make mistakes without it being too expensive, and learn from your mistakes and successes, and then work your way up to producing in greater volumes.
Also, I'd suggest you get yourself a kitchen scale for measuring and weighing herbs very soon, you can find them inexpensively in kitchen specialty shops. The vast majority of home herbalists do their work in their kitchens using ordinary kitchen equipment, not in labs using lab equipments.
