How great is Massive Bloom? I intend to find out ordered on Amazon, delivery on Wed,Fri we'll see, I have been using Dyna gro Bloom w/ FF Big Bloom which has earthworm castings & bat guano. I used Humboldt Nutrients Big Up Powder as a "booster" npk ratio: 0-33-23" & my plants were good, really good after 2-3 months "cure". I'll research Massive before I use it to find out what is recommended & what others have done,Cheers SS
