Peruvian seabird guano

[CoolBreeze87]

I am starting an outdoor grow soon which will hopefully get started next week. I have a question on peruvian seabird guano(npk 10-10-2) in the pellet form. I was planning on adding peruvian seabird guano to the bottom of the holes to supply the plant with nitrogen and phosphorus when the roots get large. I was hoping that by the time the roots reach the peruvians seabird guano the plant will be entering its early stage of flowering and will be able to use the nitrogen for stretching and the available phosphorus to begin flowering. I am also planning on mixing mexican bat guano (npk 9-3-1) into the middle and upper portion of the hole to supply the plant with nutrients during the vegetative stage. The problem is im not sure if its worth it to add the peruvian seabird guano to the bottom of the holes because a memeber mentioned to me that the nutrients might just get leeched away from the water. I figured that since peruvian seabird guano is slow reacting and takes a while to break down that this wouldn't be a problem, and the roots would reach it at the end of veg/beginning of flowering and help to kickstart the formation of buds. Does anyone think this is a good idea? Does anyone have experience with using peruvian seabird pellets? Do you think i would just be better off to mix the peruvian seabird guano in with the soil mix and leave out the mexican bat guano, and just supplement with mexican bat guano in the form of tea's or top dressings? This is my first grow so im nervous and little unsure of things, and there's only so much you can learn from reading. I guess im just afraid of really screwing up my plants and having no harvest. Ah oh well im ready for the practical experience to begin. Thanks everyone in advance. Good luck and be easy.

I am no expert here, but I can almost safely say that that won't work...The holes you're talking about, do you mean the drainage holes? All the nutrients would leech out, the nutrients you are trying to get don't leach up....IF you were going to add PSG, it's proabably a a better idea to get it mixed up into your soil. From what I've read on here though, adding PSG to your soil is only a good idea in small amounts, if any...because it is so alkaline...it's probably best to use in a tea.

Again, this is just prelim info from a non-pro...

the holes i was speaking about are not drainage holes in containers but the holes im digging in the ground. I've heard an old guerilla grow trick is to add an amendment high in phosphorus to the bottom of the holes so that hopefully by the time the roots reach it the plant is nearing flowering stage. I was only planning on adding 1/2 tablespoon/gallon of soil or less.

What im concerned about is that since the PSG will be at the bottom will water leech away the nutrients? Meaning is it a waste to even bother trying this.

[CoolBreeze87]

thanks ill think thats what ill do. Also if psg is rather alkaline and my native soil is rather acidic, wouldn't this be towards my benefit?

 

[Suby]

Yes but you can't be sure what the final ph result will be, make sure you include 2TBS of dolomite lime per gallon of soil mix to buffer the mix to high 6's and keep soil ph in check while adding calcium and magnesium to your mix.

 

[CoolBreeze87]

I am planning on adding dolomite lime to my soil mix already. If i regularly water with a tea made from worm castings, liquid kelp, and liquid molasses should this provide enough micronutes and calcium and magnesium, or will have i have to add something like epsom salts to the tea as well?

PSB is hotter than all hell [ take six ounces of water and drop one pellet soak it for 1/2 hour then stir and measure the ph ] I use it all the time but only mixed with water [ I use it as a ph up substitute ] I can only imagine it would burn the roots when it came into contact with water as well as skyrocket the surrounding soil ph.

 

[CoolBreeze87]

so is it a bad idea to use peruvian seabird guano as a soil amendment and just use it in tea's?

 

[Verite]

Its always a good idea to measure what youre amending the soil with to see how it will effect the ph.

 

[CoolBreeze87]

hmmmm... so you do think i should just skip out on the peruvian seabird guano and just amend with mexican bat guano( i will also be adding kelp meal, greensand, dried molasses, and dolomite lime), and just use a veg tea of mexican bat guano, liquid kelp, worm castings, and liquid molasses. For bloom ive got budswel to replace the mexican bat guano. I could always use the peruvian seabird guano for my veggie garden if anyone knows if thats straight?

Why not use the PSG in your teas? It should work well for you in that manner.

i think it will be fine.that psg in the bottom will allready be broken down by the time the roots hit it .i would also add some earth worm castings and lime in the hole.when the roots get ther time and the nature of organics would have made it ready for your plant .

I mix a good dose of bat guano (0-??-0) in with soil in the bottom 1/3 of my pots. The top 2/3 smaller amount of guano and add worm castings. That way, the time the roots hit that 1/3 they're in flower and ready for the P. I see no reason why what you said would not work. Time the roots get that deep, the plant will be able to withstand higher doses of nutes.

i notice that the roots in my 2.5 gallon pots go to the bottom of the pots witin a week of transplanting, during veg. if the psg is too hot, the roots wont go there and thus they will be stunted. personally i dont agree with layering in pots. the roots will go where they want to go, and fast if you encourage them

 

[CoolBreeze87]

yeah im going to skip the psg on my ganj and just experiment with it on my vegies. Either that or save it for an indoor crop.
