Guano Questions

Is guano good just because it's got lots of Nitrogen or Phosphorus? Or is "special" because it has other benefits for plants, besides it's value as fertilizer?

Will High P guano produce better results than something fish bone meal or a bunch of rock phosphate?

And is there much difference between High P Bat Guano and High P Seabird Guano?

I use bat guano for P. Label says its high on macro nutrients apart the npk specific value. As long as you cover the npk needs you re fine. Very happy with it nonetheless, bud is proper good

Seabird guano will burn the shit out of your plants. As will bat guano. But bat guano is the king of fertilizers. It's like a top fuel dragster so drive carefully. Real easy to use too much. I don't use it in containers. Too much. The 7-3-1 deposit isn't so hot. Seabird will burn faster than anything. I think every grower perhaps will have to learn the seabird lesson.
Fishbone and rock phos are better choices unless your growing monsters and want to carefully use some seabird.

True true! You gotta go very easy on it. Been using it for years but yet never a flawless grow for the whole plant. Weed comes out great but some phenos take it very rough, just make sure theres no over/under watering when this happens.
Im a week out from adding the flowering dose and i could never stop from adding just another tbsp... mistakes!! This time im going very easy. Ill report
