First time used, might of been coincidence but everything seemed to start growing a lot faster

I hope it helped making nutrients ready. I didn't do a side by side but added microbes to tea with a good food source ( alfalfa, kelp meal) I'm sure had a nice community of microbes.

I like the idea of it, but would need to do a grow without after I have more experience to really see the difference.

Mammoth is a staple for me as my bio agent and now also my IPM! Great and reputable company that works with growers.

Makes the stems of plants very fat and sometimes that can actually negatively effect yield. I'm starting to suspect that it's mostly malted barley
