I haven't had to add ANYTHING to my crops except that I habitually add Hygrozyme after transplants and shocks and after every flush.
I have been running in Hydro for a few years now. I have been using V+B for about 2 years of that. I bought a 5 lb RO/Soft to try it out, 3 weeks later I bought the 25 lb bucket to last a while. I'm almost ready to reorder the stuff. It looks to me like +Life is a superthrive/myco/beneficial blend that could replace some other products like Great White (I wouldn't switch away from GW, but hey, it's out there.)
I was a die-hard GH Flora user before V+B.
You know, I edited this for content twice and it still looks like an ad...
tldr; Don't need to add anything if you use the RO/Soft water formulation with RO/Soft water.
Peace!
Cuebossa,
Those are some pretty girls, may I ask what strain?
