Ohso, thanks for the info.
i'm going to be flowering within the next few weeks and going to pick up some of the guano but wondering how you could use it for flowering.
im guessing tea..but would you use the 0-7-0 or mix both?
.
Jollygreengiant I prefer using High P Guano Tea, like the 0-7-0 stuff we are talking about during flowering. I mix two tablespoons of it to one gallon of unchlorinated water & bubble it for a day or two, with a cheap aquarium air pump / air stone. You could throw in 1/2 a tablespoon of the Higher N, to provide some N, with no ill effects.
.
Then use your guano tea - one quart per gallon of soil (in containers / 1 gallon max) or the 1 gallon per plant, when they are planted in the ground. Throw the left over crud in your compost barrel.
.
Now, some people are going to say - " Well, I use allot more ". Well, that's fine. I don't. I fertilize slow & steady - which guarantees I don't burn my plants. Remember, with 0-7-0 Bat Guano, that number represents what P is readily available (soluble) - it actually contains anywhere from 7 to 14 percent more P, which will break down slowly over time. So, going easy ensures you don't over do it.
.
If you fertilize slow & steady - it's much easier to read problems in your plants. When you throw Mega-Doses of this & that at them - sorting out whats going on - becomes much more difficult.
.
More plants are harmed by overwatering & overfertilizing - then all other problems combined.
.
Hope this helps...
