FoxFarm Tiger Bloom is produced for soil and hydroponic systems. It is a powerful, fast acting, with high phosphorous concentration fertilizer that also contains just the right amount of nitrogen and many trace minerals for plants.
I have nothing to compare it too when growing cannabis. It seemed to work fine but I feel it's bit too over complicated. I am trying a completely new method now but I won't rule out any method until I have a few grows of different methods under my belt.
