Hey sounds good from here dude. the airpots work wonder don't they? I'll personally never go back, got a grow using the 20l aka 5.2 gal right now and my girls have been loving it. Good move with the clay pebbles at the bottom I did that when I ran coco so it wouldn't all drain out the bottom, now im in just straight soil. Canna is a great nute line I used to use it myself but switched over to Heavy 16 this stuff is killer and blows canna out of the water, though i still use cannazyme. Smoke and love!
