The reaction created a gel like substance. I believe it was the chelate action of the amino's that coagulated the silica. It felt like rubber.

What kind of concentration were you attempting to mix this at?

I had spectrum retest Si and they got close to same value just fyi. I don't know what the deal is with it.

Thank you guys for the aminos tip. I think I'll use small amounts of calnit with the pacific gro while following sap no3.

Limit it to 0.7 grams Agsil 16h per gallon for fertigations, even lower for frequent fertigations. At this rate you are adding ~100 ppm SiO2 to the solution, with ~120 ppm being the solubility limit for silica(SiO2).

My recommendation for mixing agsil 16h into multi component solutions is to add it first, alone, mix well, then lower the solution pH into a reasonable range, ie ~6.5 pH, then add the other components to the solution separately, mixing them in completely before dumping in more of anything.

It is my understanding that both Logan and Spectrum use the same analysis method for determining silicon.

I do not see fertigations as a means to increase soil/media mineral analysis.

Has anybody used products from Agricultural Solutions?

Cape shark is the main ingredient in the cold processed hydrolysate they offer. Anybody have feed back? They are the closest to my location it would seem.

Why is that?

Hazy whats your fertigation set up like? do you use something like a dosatron into a drip system?

Any thoughts on speed of the ferti-nitro? It seems like really fast uptake but It's actually nh4. I didn't add much nitrogen to my greenhouse and the amino isn't cutting it so far. I'm getting ready to tip my hand a bit more.

Any feelings on blending it with topdress and applying? I had granulated soy amino once that was mixed with a binder (corn starch?) I applied that product as topdress but don't have a source for it currently

It is soluble organic nitrogen, which will of course go through the entire nitrogen cycle if given enough time in the right environment.

can we go more in depth on this line of thought? is it CEC/adsorption?

The quantities being applied are so small that it is difficult or better yet, impossible that they will show up dramatically in a soil analysis.

Many believe that the balancing concepts are necessary in metals, etc... like the bases. I have not found that to be true. If you run consistantly the right ppms, you can "simulate" the balancing formulas. But thinking you are going to make correctives to balance is a fallacy unless done in the physical mix and I would argue that it is a waste of money in most cases.

Anyone going to the Cannabis Cup June 3 in Santa Rosa?
