I've been curious to try one of THESE out myself as I've seen others use them
with really nice evenly distributed bubbles throughout. Gonna get some after this
round to see if they actually make a difference.
Although I'm running 2 diff strains, I have 4 of those Sunleaves stones and 4 Wal Fart blue air bars. Kind of a test, with 4 of each in seperate DWC Igloo coolers.
