Kelpak has a slight seaweed odor right out of the bottle, but it is not really noticeable in the as-applied solution. Reminds me of being at the beach!
A lot of folks ask for application rate recommendations, and the simple fact is that nobody has a lot of experiences with it and orchids, so WE are the ones learning it. The recommendations I got concerning ornamental plants from the producer are as follows:
As a transplant dip (let it soaks for several minutes) - 1:128
As a drench (i.e., as a watering additive) - anywhere from 1:500 up to 1:128. (Never apply at less than 1:500, as there is no effect.)
Some non-metric, household measures for concentration:
1 oz/gal - 1:128
1 Tbsp/gal - 1:256
2 tsp/gal - 1:384
1 tsp/gal - 1:768
3/4 tsp/gal - 1:1024
Concerning the continuous/periodic application, there are several theories - or should I say opinions - out there. The producer recommends never treating more than every two weeks. The thought being that the application of hormones "turns on" biological processes, and they continue to operate for about that length of time. More-frequent application can over-stress the plants.
The approach taken by others is to substantially lower the dosage rate, and apply it with every watering.
Personally, I have been applying at about 1:400 at every watering, and don't see issues at this point.
