most of these are available via garden store/ agriculture stores
hope the info above helps in your choice. i tend too like the bonemeal with its 2-11-0 maybe good for flowering/budding up

Nice Post...Good Info... All of it shows just how reasonable organic sources of fertilizer and/or soil amendments are.

The only one, I would steer clear of is the sludge. A lot of commercial worm farms use it as a cheap feed & unfortunately Big Agri Farms (10,000 acres farms) use it at the end of the season to fight errosion. That's another dangerous thing these Mega Farms (who use only chemical NPK fertilizers) do to the soil, concentrate heavy metals in it - using sludge, which saves them a few bucks per acre. Big Agri - their business is not about the nute value of food - all about the dollar - Yuck.
.
If you buy worm castings from larger worm farms - it's always a good ideal to inquire about the diet they feed their worms. The digestive tract of the worm is amazing an will break down / improve most soil - but sludge from large cities always has more heavy metals - because of industrial pollution - and guess where some of these big worm farms are located. Yet another reason to get a cheap Rubbermaind Plasic Tote, and make your own worm farm. Know the source of your amendment for sure.

+ rep for the good info...

Keep it Real....Organic....

thank you ohsogreen

another thing i stumbled across was this:

homemade liquid fert:

grass clipping (lots of N)
tree leaves
soft /medium chopped twigs stems etc etc.
weeds/ large /small

place all your greenery into a sack / wheeliebin / bin and fill with water, not too much. now leave it alone too ferment. remember leave it dont mess with it at all. after a month or so you will notice a barnyard type smell/ agri type smell. and should notice that the liquid has bubbles and scum on it. this is the bactiria doing its job and breaking down your green into a liquid fert. after a month in warm weather ( 3 months in colder climates) your left with a very good liquid fert.

this stuff stinks and if place on skin will not wash away too well so strong rubber gloves are needed for extraction. placing the greenery into a sack allows you too syphon of some of your liquid, refill your bag and top up with a little more water, replace lid and leave too ferment again.

there was no info on how much too use or its ppm/ph.

hope this helps everyone with a chemical free grow. please ignore the waste sludge part, as mentioned with ohsogreen it is not an ideal fert too use.

thanks tamzi...gave you some rep

nice post im looking for a organic bloom food for a hydroponic any ideas????\

hi candy, sorry i havent answered your question.

i personaly am a soil grower. love getting my hands dirty so aero/hydroponics are alittle above me.

bone meal: high in K

personaly i think most ferts/nuets you purchase are going too have some kind of bone meal added its a very high K with a typical nuetriant count of 2-11-0
this could be a very good bloom fert but is strong. i would ask a few aero/hydroponoc growers see if any have used a bonemeal mix as a subsitute for thier normal bloom ferts.

Tamzi

htanks for your replie i ended up just going to the hydro store and went with a supposed
organic nute. called age old bloom the contents didnt have anything that i couldn't say and it was stuff that i reqconized so i think that im safe the npk is 5-10-5 so im hoping that it'll do the job.

yup should be fine low N-k and high P ideal for bloom/flowering. hope you do well with your grow.

New Addition too the fert post. this fert is a somewhat toutchy subject on this forum. the fert in question is human Urea also known as pee.

Urea:

Typical nuetriant count: 46% nitrogen
Application rate: one part Urea too 10 parts water
Collection period: mid day onwards. not used if have taken alcohol/ or intoxicated with alcohol.

some more info anout the application and use of Urea.

Urea, a white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer.
If properly applied, urea and fertilizers containing urea are excellent sources of nitrogen for crop production.

After application to the soil, urea undergoes chemical changes and ammonium (NH4 +) ions form. Soil moisture determines how rapidly this conversion takes place.

When a urea particle dissolves, the area around it becomes a zone of high pH and ammonia concentration. This zone can be quite toxic for a few hours. Seed and seedling roots within this zone can be killed by the free ammonia that has formed. Fortunately, this toxic zone becomes neutralized in most soils as the ammonia converts to ammonium. Usually it's just a few days before plants can effectively use the nitrogen.

i dont say use it or dont use it. this addon was too show that UREA CAN be used as a form of high nitrogen and clear up this myth about using UREA. most agri ferts have Urea added too them the food we eat was grown with urea too !!!
