Since I copy everything you do I'll consider that! My canna bricks are salt free though. I throw brick chunks in a wheelbarrow and hydrate them with 600 ppm water (blend of calmag and MC and its about half strength) a few days ahead of time. I leave it open in the garage so it can dry out some. then I load up solo cups with it and put them in the tent ahead of time to warm up before I drop in germed tap roots. Also I'll load up my pots at this time even though I won't need them for 10 days or so and keep them hydrated a bit until I'm ready to transplant.
