Irrigation and Fertilizer Confusion with Auto System

[D&S Mabel]

Hello All!

I recently rearranged the way I handle my sun & water loving orchids. I set up a small, automatic watering system on my pool deck. So far, the results have been very positive, lots of new root growth and flower shoots appearing on most all of the plants - really shows that I was underwatering and inconsistent with my previous care methods. My setup looks like this -


I put up a length of galvanized pipe and attached 1/2" flexible plastic pipe to it with plastic wire ties. I then added 10 misting heads, rated at 10 gallons per hour to the plastic pipe. The watering is controlled by a timer and I added a filter/fertilizer attachment that works by adding a powdered, water soluble mix to it which desolves during watering. The plants are in direct sun for about 5-6 hours per day and I run the setup 3 times a day for 10 minutes each time.

What I can't figure out is how much fertilizer to add to get a certain concentration. The filter/fertilizer attachment doesn't have any mixture ratios associated with it from the manufacturer and their website was no help either.

Any ideas would be appreciated!!
