So, if I want to replace some or all of the rest of my hot tub chemicals in the same way I've been finding inexpensive alternatives to hydro nutes, how would I go about it? That's what led me to thinking about 'total alkalinity'... or rather, wondering WTF they're talking about.
can there be a chemical change in the plant post harvest that could be adversely affected if trimmed or "bruised" while wet?
This is the equation you are looking for:My question(s) are this: First, what am I getting, exactly, by doing this first method? I can see that the volume of crushed shell is dramatically reduced, though not eliminated. What am I ending up with using the acetic acid+egg shells, though?
Second question: Would I gain better access to both the Ca and P present in shells if I were to bake or char the shells prior to putting them into the concentrated acetic acid?
Third, is there a better way to do this (make use of leftover shells besides composting)? My soils are Ca- and I often experience problems associated with Ca-, including in my tomatoes, peppers and squash quite a bit of blossom end rot that is *not* related to watering.
If I understand you correctly, I'm getting yet more CaCO3, or in other words, more fucking carbonates, yes?
I don't need more carbonates, I need more (organic and available) Ca! Bloody fucking hell, this shit is a pain in the ass sometimes, I swear. <facepalm>
Will nutrients quickly degrade when exposed to high temperatures?
If only it were that intuitive. Solids can be equally as reactive as liquids--and sometimes degrade even more easily. It all depends on the chemistry, and this is again substance specific. As for telling if nutes are bad--without very expensive machinery and knowledge of the original absolute composition of the solution, no. Physical changes are your only guide (smell, texture, pH, etc.)I would guess that liquid ferts would degrade faster than powders - is there any way to tell if your nutes have gone bad aside from physical changes?
How about enzyme products like Hygrozyme/Cannazyme? Nothing in my line up is over one year old but some of them have been exposed to substantial temperature changes.
Where or how would someone go about testing ISO or BHO for remaining solvent in a non med state? That's a pretty vague question that's almost not chemistry related.
I have been toying with some triacontanol and bap6 from ebay any experience or tips with them?
There is not a feasible option for this sans expensive/difficult to construct equipment.
The chemical compounds are too similar to extract them from one another selectively for an assay.
You could certainly buy an IR spectrophotometer and I could easily train you to spot the chemical signatures of these compounds on a spectrum from said device--without that or another analytical instrument (this would be the cheapest one to buy that will work for this purpose), this is essentially impossible.
The best way to ensure that you have removed all residual traces is to properly purge the material.
Extracting into a more easily removed material such as methylene chloride or chloroform is also an option.
