I feel like 1L is a good size. Good "bang for your Buck" in terms of their size vs yield. I am currently running an experiment of a 2L vs a 1 Gal vs a 1L in coco to try to see which size i like best in my cab with coco as a medium(yes another one). 1 gal is almost too big...
good to see you CM!!
that's really nice - I'm interested in 1L coco... ^.^ let me know how that size work for you mate!
This thread helped inspire my set up
