ROBB - 2 things:
1) You should not soak Orchiata bark, as that extracts some of the dolomitic limestone they use in the curing process. I found that a better way to pretreat it is as follows:
- Pour very hot or even boiling water over the bark - about enough to get it good and wet.
- Let is stand until cool (~15 min or so)
- Then pour your Kelpak/Quantum solution over it.
The hot water treatment opens up the dried cell structure so it can absorb and hold more water (just like an extended soak, without the degree of extraction).
2) The bark/perlite ratio you find to be “correct” will depend upon your growing conditions, selection of container, frequency and watering, etc., so Clawhammer’s experience may not be particularly useful. I imagine it’s a lot different in Portland than in Alabama!
