I am not sure about gravity or purple max. I know for sure bushmaster works. You know that too.
I have used gravity and purple max every grow so i have nothing to compare it too.
This grow I will do the test.
2 plants = nothing
2 plants = purple max
2 plants = gravity
2 plants = gravity and purple max
