Its like this, blood fish and bone on its own is usually 7:7:0 the last people who made it were eclipse, not sure if they are still in business, nearly all bfb has added potash to balance the npk in the way of added murate of potash or sulphate of potash so they are not organic in any way. The nearest you could say is it is an organic based, a term used by the horticulture industry to indicate that it is sort of organic.
BFB like national growmore is what is called a base fertiliser, ie it is used to dress top soil as a medium term balanced fertiliser that will supply extra npk to garden soil for several months. Remember that garden/farm soil also has reserves of nearly every nutrient needed by plants.
Outdoors plants have unlimited soil to grow in dependent on how competitive any other plants there are in the immediate vicinity competing for root space.
Indoors we grow in pots in compost, of which there are mainly two types that we as canna growers use, they are lightly fertilised/light mix and multi purpose/allmix, both can be used for seeds/cuttings and growing on. Multipurpose has many times the amount of readily available fertiliser that garden soil has but only for a limited time. So plants can be grown for a few weeks before the roots extract all the readily available nutrients, once these run out feeding is needed with liquid fertilisers. This is because the container limits the volume of compost and in turn rootmass is limited to a tiny portion of what the plant would naturally grow.
You still get some nutrients released, but at a far slower rate than the plants need to flower and crop well.
With light mixes there is very little base fertiliser or should we say nutrient reserves, so with these liquid feeding is needed from once the plants start growing away well.
BFB is not a good fertiliser as a base in compost as the blood gets used very rapidly leaving the compost depleted of nitrogen. Secondly cannabis is very intolerant of sodium, so while bfb could be used to supplement real soil for gorilla growing, if its potash supplement is made up with murate of potash it is likely that it will either damage or inhibit cannabis. On the other hand if the supplement is sulphate of potash bfb is a quite good fertiliser to dress the ground with, and a light top dressing round the plants after a couple of months is also good.
So its not good for pot growing and depending on type could be quite good for outdoors in real soil if you don't mind crude chemical fertilisers.
Finally liquid fertiliser are blended to have exactly the right balance of nutrients that the plants need to grow or later what they need to bloom.
Q. how do i make seeds?
A. You take a splinter off my cross, tie a few hairs to one end of it, dip the hairs into the pollen and lightly brush the pistils with it.
