I am very confident in the properties of SM. To me, it is fool proof.
Today I did some experimenting:
1) ziplock storage bag, cut along one side. I laid the baggie on a flat surface and I laid wrung out SM on the inside. Then I sprinkled moist turface (very little) and a little seaweed/kelp meal (like seasoning with salt). I laid the cuttings on the SM about 2 inches apart and rolled the baggie up with the cuttings inside. If you can picture making sushi rolls. The tips of the cuttings stuck out about 2 inches max. Held the pack together with elastic bands. After I had about 4 "packs" I rolled all of them up in a towel to keep them dark and another few plastic bands.
2) I am trying the baggie method with only a little moist SM in the ziplock.
3) Attempting root two cuttings in a cup with water using an air stone from an aquarium. I heard it will work. Lets see...
I am using Chilean 5 star that I found in a huge compressed block 2.5'x2'x2'. I let it soak for at least 15 minutes in slightly warm water. When I am ready to use it, I squeeze out the water firmly and separate the long threads. If I am using it for cup-rooting mix (turface, perlite, SM ,hydroton, and a little compost), I shred SM first before I moisten. In the applications above, I leave it "whole" so to speak.
I will try to post a pic of the results.
Thanks!
