Hi Everyone!

About 6 weeks away from the end of my first ever grow, 4 Thai bagseed girls from some lovely grass. A few ups and downs but overall things are looking very promising.

Have been looking into various substances as potential nutrients.

Has anyone used Bone Ash before, it's big on .P. It contains 40% phosphorous pentoxide and 55% calcia.

Any views or thoughts would be greatly appreciated.

Cheers.

Hello crankey1
Bone ash and bone meal are excellent soil ammendments for sources of phosphorous. The problem is, they need to be mixed well into the soil, and require a bit of time to be broken down to a form easily available to the roots. If you have only six weeks to go, it may not be long enough for optimum results.
To use it at this point, spread about one tablespoon per gallon of soil on the surface, and rake it in as best you can with a fork. Don't tear too many of the surface roots.... just try to get it mixed in well.
For immediately available organic P, look into bat guano.

Also, if you are in a country where Mad Cow Disease is an issue, wear a mask when you fool with bone products.

Personally, I wear a dust mask whenever I work with bone or blood meal. If I don't, I start running a slight fever right afterwards, which tells me my body is fighting something off, and I imagine if you breathe enough of it you could get pretty sick. Mad cow disease or no, slaughterhouses are not exactly a paragon of hygiene.
