Sub-culture B or Sub-culture M ?

Hi there !
Just foud out that Hydroguard from Botanicare is not sold in Canada anymore! It's illegal ... LOL!!!!
I was told that Sub-culture B is similar to hydroguard ,but Sub-Culture M is interesting too.
Wich one is better suited for DWC ?
Thank you !

go to the GH website. if i remember correctly, it's pretty well explained which one does what

I use both. They worked miracles getting rid of a bad case of slime.

You only need the one with bacteria, fungi don't benefit hydro. The mikos in dirt create a symbiotic web with the root system to transport nutrients, I don't believe it works like that in hydro. The bacteria work because they are small single cell organisms that work symbiotic with the plant. If you want the phosphors chelating/fixing bacteria for flower you want Mammoth P. I use Orca in veg and Mammoth P in flower. Oeca and Subculute B is the same almost.
