I was wondering if you just use guano or do you add any secondary nutrients to your teas(which i guess are contained in different types of guanos, sea weed extract, fish emulsion, molasses) I dont mind spending the money on all of those since its really cheap. Would you recommend mixing a couple different nitrogens for veg and a couple different phosphorus for flower so its more well rounded or keep it simple. I know i cant force feed them nutrients just want a healthy mix.
one more question, if im brewing my tea with a airstone in a bucket out side for a couple days how long does the tea last? Can i store it or just let it keep brewing for a couple weeks. Thanks
.
I mix & match... It requires only very basic math skills. I use very dilute seaweed at weeks 6 & 9 only... OK, I already know what your thinking....6 & 9...LOL
.
NPK values of common organic amendments / fertilizers -
when making teas - use only unchlorinated water. If you only have tap water, leave it sitting in an open container for two days - 99 % of the chlorine will evaporate.
.
Rabbit Manure (fresh, source: your pet) NPK 2.4-1.4-.6 - use one cup per gallon of water.
.
Bat Guano (fresh, source: Ebay, Hydro Shops, A Cave) NPK averages around 10-4-1.5 - use two to four tablespoons per gallon of water. (I'd use only two tablespoons the first time). Aged - NPK averages 0-4-0 up to 0-12-0. I like 0-7-0 (aka - Budswell) myself; because the P number represented is the soluble (immediately available measurement only). High P Bat Guano
averages two or three times that number in total P. The other just breaks down slowly over time. Mix it the same way as fresh - start low & build up slowly.
.
Chicken Manure - composted only - don't use fresh (Ebay, Hydro Shops, Garden Centers, your pet) average NPK 3.5-5-3.5 varies by diet & composting method, some as high as 6-8-6 or as low as 2-1-2 - use one cup per gallon of water.
.
Worm Castings (fresh, source: Garden Centers, Ebay, Commerical Worm Farm, in your own vermicomposting bin) average NPK 1-0-0 - add four tablespoons per gallon of water.
More is not necessary only .1 % N is soluble, the other .9 % breaks down slowly over time. That is a very weak source of N. The reason WC's are so good, they add trace minerals & good microorganisms. That's their real appeal.
.
Seaweed - (fresh, dried or composted - source Garden Centers, Ebay, Hydro Shops, the beach) NPK varies with source (use very dilute) half of their recommended dose - at weeks 6 & 9. Yes, LOL...again...
.
Unsulphured Molasses - (fresh, source: Grocery Store) average NPK 5-1-3
use one ounce to one gallon of water. I like Brer Rabbit Brand.
.
Fish Emulsion - (processed, source Garden Center, Wal-mart, Ebay, Hydro Shops) average NPK 5-1-1 Use as per label's instructions - usually one tablespoon to one gallon of water.
.
To mix up a very useable, soil growing tea - shoot for a NPK of no higher than 10-5-5, because of the nature of Organics (slow released). Overuse/feeding with toxify soil just like over use of chemical fertilizers.
Only use one quart of your final tea mix, to each gallon of soil, when you feed. I recommend only feeding every two weeks. & just water in between (and/or use Super Plant Tonic).
.
At flowering time, shoot for a NPK no higher than 2-8-4. Keeping the N below 2 helps stop veggie growth & directs more of the plants energy to flowering. Higher P & K numbers are OK, but I try to stay at or under the P-K I have recommended 8-4. With Organics more is not better, because you want to feed low, slow & steady for best results.
.
Once I brew tea, I try to use it within (3) days. After that, the good microorganisms start to slowly die & the non-oxygen loving microorganisms (the bad guys)
may but not always, start to take over.
.
It is possible to bubble indefinitely, if you add a small amount of N to the mix each week to feed the good microorganisms. The N content will continue to decline slightly / slowly & the P & K usually go up just slightly.
.
If you introduce, beneficial microorganisms to your tea mix (like mychorizzal fungi) when you start brewing it, it makes it even better. They out compete for the food source (N) reproduce, kill off the bad microorganisms, excrete natural antibotics & make everything in the tea mix HIGHLY Soluble.
.
Sources for these good fungi & bacteria (Hydro Shops - a product called Sub-Culture or Myco Magic, Ebay - a product called Super Plant Tonic, or talk to a agri-student at your local college - let them culture you some for a few bucks - kids in college always need money & they keep dry cultures of these things on hand.)
.
Ok, now just get out a pen & a piece of paper - mix & match - stay within the provided limits & you'll be brewing a great tea in no time.
.
Hope this helps.
Keep it Real....as always Organic...
