So, 11 days into the experiment, and I've only had two seedlings begin to emerge. Both of the seeds were scarred all the way to the embryo with a fine grit emery board, and both were planted in loose coconut coir. The temperature has been a constant 74 degrees in the germination tray.

So far, it seems the best bet is to scarify the hard seed coatings down to the embryo before planting.

Pictured below are the cotyledons emerging from the first seedling to sprout.
