Very nicely done and a very informative thread.just a couple of helpful hints for next time. When you're spraying out the GS lay the tank on its back and you wont have to worry about the sagging. Next, after you're done pressing the coco fiber in and its dried overnight just dump out the excess then use a shop vacuum to clean up lose particles and stuff in the crevices. It a cleaner alternative to blowing it out especially for those who work on their vivs on the kitchen table.
