I use Kool Bloom powder myself ,
It's npk numbers are like dbl. the npk numbers on the liquid = powder lasts a hell of a lot longer . 1.5 lb. container has lasted me 3 yrs now and somethings always growing here .

It's crazy strong - I suggest starting off w/ 1/8 teaspoon per gallon -n- not 1/4 teaspoon like the directions recomend to avoid any possible burning .

I use it week 4 of bloom till I flush . I noticed a huge difference in smell , so be prepared for odor control . Yeilds also went up too .

Peace
