Is there any difference between food grade 34%h202 and non food grade?

I have some funky smell coming out of one of my buckets indicating a root zone issue. Never had one before, but something is mucking things up. I had to go on a run for some 35% h202 today. One of those things you simply can not buy online due to shipping restrictions. I was blown away at the price. $12.09 for a gallon, however it's 34% and not listed as "food grade." I'm only using the stuff for sterilizing some nasty stuff that's brewing in my root zone of that one bucket, but I was curious if anyone has any experience with this brand of 34% h202? Paid about $26 for the last gallon of food grade h202 so. Use to pay $20 for a gallon of the food grade, but those days are gone it seems. I'm going to reach out to the company just to verify there aren't any stabilizers in it. Nothing on the label is specific about stabilizers. I just don't want to add it to my res thinking it's only h202, and I wind up adding things I don't want in there.



I did some reading and it looks like it is a "technical grade." That alone doesn't indicate the presence of any stabilizers though. I'll get a hold of the company to find out unless someone here on RIU has the info and beats me to the punch

i know the food grade is used for aseptic packaging (those juice boxes for kids as an example)

but yeah, i'd contact them and see what they say is tech grade vs food grade.

Fired off an email. I'll report back with their response. Hopefully it's all good for what I plan to use it for

I never realized how many uses this shit had until I started growing. Apparently it's used extensively for sanitizing in the medical field. The last thing in the world I'd have ever considered it being used for is sterilizing juice boxes, but it makes sense. Bacteria is everywhere, especially in the manufacturing process. Don't wanna get kids or anyone sick from dirty packaging. Still it's just one of those things that make ya go,"huh?" H202 for what?

One thing that makes me feel a little better is I saw this item listed on a beer brewing website for sterilizing brewing equipment and such. If there were any additives in the h202 that would sure seem like a dodgy product to sell their customers who are using the equipment to then brew beer that they're going to ingest. When in doubt ask someone smarter than yourself. I'm on it

i know regular h2o2 contain stabilization agents
like phosphorous acid etc ..

i think food grade do not contain anything else than h2o2
but its way more unstable

This stuff doesn't list anything, but it has a strong odor and particulate floating through it. Like calcium sulfate precipitate you'd see by mixing magnesium sulfate and calcium nitrate. It's going back tomorrow. I'll grab a gallon of food grade. I just don't trust it. It's also half the price of what I've paid in the past. Something ain't right

strange
i dont think you should find solid particles of any sort

No sir. It should be pure h202 mixed with pure water. Dude at the grow store was like, "man we never have a problem with that brand, but yeah bring it in." I don't care what their usual is. All I know is this thing has shit floating in it and that isn't right at all. Won't make this mistake again. I should have just asked for the brand I always buy. That's what I get for not asking

Shit, something a little embarrassing just happened. Knowing that human error is the most prevalent type of error and knowing the half a retard I can be sometimes I thought I better put a set of goggles and gloves on to verify the contents of the h202 jug are actually contaminated. I had a lingering suspicion I poured the h202 into a dirty container that was the source of the floating particulate. Not the h202 or jug it came out of. It was a little 150ML glass container I use to store my digital tds meter in. Definitely not a clean container. Stupid me. So I suited up so as not to blind myself or burn the skin off my hands. We talked about that half a retard thing, right? So I poured into a 1/2 gallon clear polycarbonate jug. Crystal clear. A few micro bubbles at the top of the water line, but zero particulate of any kind. Operator error strikes again!

I would much rather figure this out at home in my basement all by myself and share it with y'all on RIU. If this had unfolded at the counter of the grow store in front of other people my level of shame and embarrassment would have been immense. You guys are cool. Fuck the dudes at the grow store Move along. Nothing to see here.

But in all seriousness I will purchase food grade moving forward. While there may be no perceptible difference I want the container to say "food grade", so I can use it in my refrigerator and for general cleaning purposes around sensitive areas of my home. Non food grade still can be used as a cleaner, but not in sensitive areas where food is stored or present.
