When and How should you use Bat Guano?

[Mike Smith]

:Stones slap:
I am interseted in getting some bat guano and i am not sure of a few things. I want to use it to Bloom and have been looking at some chinese stuff that appears much cheaper then the US Sunleaves Guano range. The NPK's are 2-15-1 and 1-10-1 and they are around a tenner for 1 litre. I think I know about making tea for the plant's, but how do I include it within a scedual. BioBizz Grow and BioBizz Bloom are the feeds I will be using for my next grow. Is NPK 2-15-1 a little high or should I go for 1-10-1? I would very much appreciate Forum advice on this matter. My goal is to eventually to take the full Sunleaves range and go 100% Guano. mike

I would go with the 2-15-1 but start with half doses at first and go to full dosage later in the flower cycle.

Ok, but if I was using BioBizz bloom, is there a percentage reality involved for both or should I use one or the other?

Using both would very likely cause overfertilisation.

Go with one or another, you can mix the guano in the soil and never have to use any other fert for autoflowers.

Yes, I had a suspsion that using both ment cutting down on amounts used, where the guano seems to be the one I am aiming for. With the guano being 2-15-1 I think a quater-half-and then whole approach would be best. Use Biobizzbloom at 3/4 first and compliment with guano at 1/4, upping the guano rate until it is at 4/4 whole level. I would also folia spray and Miracle Grow spray as well a couple of time throughout the grow at 30% strength.

All bat guano is very safe you can use it up to 20% dry weight/ volume. I would suggest buying bulk high N bat and high P bat...

Is it better to top dress or make a tea for autos? I'm currently running 00 seeds chessberry auto in LC's Mix #1 with have a bottle of Roots buddah grow and some sunleaves high P guano
