dry ferts safe?

Is there anything I need to know about the household safety of the dry ferts? I haven't started using them yet. Also, which ones are you not supposed to mix b/c it creates precipitation?

Do not eat them. It probably wouldnt be too pretty. I never mixed any of my dry ferts. I added them dry and one at a time.

Too funny! Is there any risk with breathing dust from the powder if you don't mix it in liquid - I have asthma and lots of stuff bothers my lungs? I'm really thinking of long term exposure safety.

Thinking of snortin up some nitrates? Probably not safe either.

These powders are actually very heavy in mass. You shouldnt have an issue with free floating dust.

Oh. I didn't open them yet b/c I'm scared of them - not really, I'm just using up my liquid ferts. I thought they might be finer in texture. No snorting - but are they white?

The "no eating" part is pretty serious if you have four legged pets or children that visit.

I keep my ferts locked away with the guts of my plumbing, CO2 tank, etc below the tank. I installed key locks on the tank stand doors.

I've never noticed any dust issues. I have allergy induced asthma too.

The only one I've experienced "dust issues" with is GH builder/Equilibrium (if you're using that).

I mix whatever dry ferts i'm dosing into a measuring glass, pour some tank water in and stir til fully dissolved. Then I dump it back into the tank near the spraybar for quick dispersal. Seems to work fine for me.

You can dump the ferts into the tank dry without mixing. I like to have a bottle of concentrated fert solution on hand. Don't mix the macros and the CSM+B, or you might get some precipitate. I hear that it makes something in the CSM+B inaccessible to the plants.

It's the iron and phosphorous, when brought together "directly" by mixing them together in a bottle they have a tendency to form iron phosphate.

Random tidbit of semi-useless information: Ferric iron is used as a treatment for lakes and rivers, etc, where there is an excess of phosphates, it'll cause that iron phosphate reaction and precipitate out of the water column.

they are salts, so NaCl etc, KNO3, are all "salts". Not likely you are allergic.
And given saline solutions are used for asthma attacks...........less so.

KH2PO4 is used internally for enemas, KNO3, well.......I'll let you look that one up, K2SO4, not real bad effects.

Take a look at the vitamins, they have various salts as well.

Most things are okay, except for the nitrogen containing compounds or if you ate a lot of something, eg the traces.

I'm not suggesting you eat any of it, but the risk factor is very low at these volumes we deal with.

If you worked at a fert processing company? Yes, wear protective gear.

I wouldn't worry about it. I'm assuming, of course, that you're not planning to stick your face into the bag and breathe deeply, or fling them about willy-nilly.

Seriously, though, I also have asthma and have never had a problem. I dose them dry, and it doesn't kick up any dust when I measure them out.

Wash your hands after using the ferts. Just a little in the eyes goes a long way to some very severe pain..

Yup, I speak from experience. I didnt realize I knew that many different swear words.

You guys are all so funny! Thanks for your responses. Sounds like no precautions needed except:

1.) don't eat it
2.) don't snort it
3.) don't get it in your eyes

can do
