ilike I said ealier, I use canna coco as a growing medium, its great because it drains really well without having to worry about mixing perlite. it also has the ability to absorb and retain water and nutriens, and leave more available to the plant, when it needs it. that's how you can use the same solution through growth And bloom, the coco fibers only provide what the plant needs, and it about 90% organic, which is good because you get the scents and flavors of organics, with a little added manmade bonus at the end (bioboost). its a 2 part solution with additives, rhizotonic, helps prevent stress (more ratio of females to males) and its also a root stimulant, I have roots growing out of my pots into my waste! another additive to that line is cannazyme, which actually helps the plant convert dead root material into sugars for the palnt to eat! i've used many different fert lines, techniques but man I swear by this stuff now, everything is simple and laid out. oh and I forgot the best part, the whole line combined actually lets the plant regulate its own PH, I haven't tested my levels in I don't know how long... when I started with canna I was in disbelief, every time I checked the PH of the coco I was between 6-7, every time. canna is the #1 product outside of the states, and the #1 fert of the cannabis cup in amsterdam.
