LOL,
I had a success story with it this last round, i pulled out the ol standalone bubble buckets, in a non controlled type experiment(different strains),
I put 4 buckets, 1 with plain water, 2 sm90, and one earth ambrosia and earth nectar.
I have used the ambrosia/nectar before with good results, this time the roots went to shit after a couple weeks. started smelling something fierce(guessing my stuff was to old to use). After a week I added sm90 and in a couple days the roots were looking better and in a week they looked stellar. Those products stain the roots, but this was a different look than previous use, and before when I used ambrosia/nectar there was no bad smell, this time it smellled Rank.
Now DHF(one of heaths friends) over on the mag said he has been using SM90 forever, and he uses it at 5ml per gallon(recommended dose is 2/3 ml per gallon)...
side note.
It also took care of my thrips on my babies. I used it as a foliar on some basil plants outside with spider mites and it also took care of those bad boys. Although I live in New Mexico, I wonder if are mites are less vicious than the ones out in cali?
*edit* I combine sm90 with a couple other things to make a foliar spray though, including cloves, cinnamon, vinegar. which could have added to the ability to knock out pests.
