Fuck, don't do it.
I was convinced by a friend of mine, a pretty good grower too but this stuff fucked some of my ladies up. :/ as stated by many above I had some definite problems with the empire builder. I have four ladies given to me by a friend in this soil and he swore by it. I've been seeing a bunch of one leafers, and then a bunch of leaves going necrotic and dying off.
I numbered it down and have been treating those problems with no success and couldn't figure out why.
Today one guy at the hydro shop explained to me the many nats they were seeing come out of bags, and the inconsistent nature of the soil and that there were certain reasons they didnt carry every soil. "We're not Home Depot" he said.
But as he described what they saw as problems I knew that was the exact things going on with my poor girls. I also have a bunch other ladies in different soils getting the same reg and are loving life..
I've recently been using vermifire and I really enjoy it personally, I also use
mykos drops from
xtreme gardening with it.
