I too think the setup is nice, why or how did you come across this layout for the aero? the roots can grow into the rest without obstruction from another plant... that is GREAT. Just put an airstone in the bottom for the roots that will grow from the tubes and drape into the reservoir.
I'm a hater of expensive nutrients, so I wont go into that... lol
I grow diablo from a clone that I got 3 years ago, so I'm always curious when I see someone growing it if it's the same as mine. It's so distinct that I honestly think I'd be able to tell if it was the same. If you have a good clone of it, you will be happy, because the quality is so good, very dense, smells super good, a lite citrusy , almost grapefruit pungency... fucking awesome, the high is nice too, very pleasant but can make you goofy if you do to much.. I like it when I have nothing to do or focus on, but I'm a person who mostly likes energetic highs that dont effect my head so much that I have a hard time concentrating.. I hate that feeling.
anyway, I digress, I hope your grow goes great! You will enjoy the speed of aero, it's a pleasure to watch and do.
