True Living Organics - The Ultimate Guide to Growing All-Natural Marijuana Indoors (2012)

a typical 2-gallon container, I would use about 1 tablespoon in two places, on the floor of the
container (before anything else is added to the container) and just under the bark mulch layer on top.
High phosphorus (high P) guanos affect the pH of the soil mix more than the higher nitrogen types,
in my experience. This needs to be considered if using this globally mixed in the soil mix, as the pH
will be dragged down heavily. Buffering it with ground oyster shells is a good idea, but keep in mind
that too high a concentration of additives such as high-P guanos, steamed bone meal, and even
powdered soft rock phosphate (all higher-P dry fertilizers) globally mixed in your soil mix can have a
real negative effect on the good fungus in your living mix. We love the good fungus in TLO and there
are many kinds, including the mycorrhizal fungus, which are actually a critical part of TLO and any
type of growing in a living soil mix.
These are a few of my favorite dry guanos
A final note on guanos: don’t use these fresh out of the birds or bats, or else you will most likely kill
your plants with them. Be very careful when collecting dry guano from bats or birds. Many dangerous
things can be lurking, including a few types of fungi that are very nasty to humans. Always use a
respirator, and be sure to compost the guano first if at all possible. It must be at least dried before it is
safely usable in container growing.
Bone Meal vs. Steamed Bone Meal
This is one of those things that seem irrelevant when you have synthetic mindset, but let me assure you
that this is a very important distinction, and I’ll tell you why. Typically both kinds have N-P-K ratios
of 3-15-0 or so. The steamed variety delivers way more available phosphorus faster than the plant
