Hmmmm, to be honesty I have no idea what's in Companion or Essentials. I just know they work from using them on my orchids. Good luck in your search and figuring out a routine!
I agree, it's a liquid, it's all mixed and ready to go. Well for the most part, you don't have to use it full strength and can water it down, 1 part worm tea, 50 parts water.
Thanks Bud, I read about that too, but haven't found much about it here in NL. Is this something you can buy premixed..? I'm not prepared to making it myself.
