the blood thing could actually be true.before u dis this,hear me out;lets say theres a deer walking through the forest,and dies of natural causes.as the body lays there to rest and decays the flesh and blood begins to break down leaving the fluids to remain,thus including blood,but yes this is among other fluids,and remnants.so there for intermittinly objectifying the purposed statement and by assosiation the blood is included into the original statement.Now what happens to the decayed sight i might ask,well as it becomes one with the soil,new life will begin by a rouge seed.when that said seed germinates,it will grow quickly and with vigorous growth.as the plant matures and to starts to flower,it to will benefit from thus said organic and rich nutrients.by benefiting from the soil it would fruit with blooms to come.so i think u should go with it and try putting blood in the mix.it will work no matter what,it will either benefit the plant or it will benefit the soil.just try it.
just a thought.
my bong told me to say it.
