Hi Az, I would have posted my pics of my Hempy grows had I taken some
but I can answer questions too if need be. (I am growing some hempy blueberries outside) I am using Autopots now which work really well.
Another option that I use with my Hempy setup is Turface. The media has the aeration qualities of perlite, and the water holding properties of vermiculite.
Because it holds water very well, you actually don't need to have the res hole drilled up so far. Another plus for Turface is that the media is completely reusable. Generally you have to discard the perlite after a grow.
With turface you can sterilize and re-use.
