Jon, pertaining to the alternate cup method, does one pop holes in the bottom of the lower cup or on the lower sides of the lowest cup? I was thinking we pop the holes for drainage but would putting holes on the furthest down sides of the lower cup allow air circulation to increase rooting or do you think that would allow too much moisture loss. I like the taller 32 oz iced tea cups from DD so my cutting is mostly buried.
What I really like about this method (and I have little experience with it) is that the cutting can grow a visible larger roots mass before having to change it environment so the rooted cutting would have a better chance of surviving our errors.
And another plus is the cups are reusable unlike the bags (that I currently make with the food sealer and a box of old clear report covers) and root riot cubes, no additional ongoing costs other than the cuttings and selected medium.
