I know you guys recommend 50/50 coco/perlite or coco/pebble.
But I cannot find any premix to buy, what I can find is 60/40 coco/perlite or coco/pebble.
I can also find same with 70/30 mix.
Are they OK to use, even as low as 70/30 mix or should I never go below 60/40 or 50/50?
Also, is there any difference if I use coco mix with perlite or pebbles, is one better then the other when using with autopots?
Same with the 1-2″ layer at the bottom, does it matter if its perlite or pebbles, is one better to use then the other?
