Greenhouse Grade kno3


Recommended Posts

Posted

The local farm supply sells Haifa brand kno3 in 50lb bags for $22. It's their greenhouse grade and I was wondering if I could use it in bp or comps with little ill effect.

 

If it's milled fine then mixed with willow charcoal I don't see why not, but I would like to know first before I haul a bag home.

It's the GG grade.

 

Thanks,

Its good stuff, technical grade at minimum.

 

Buy it :)

In my country we have Multi-K KNO3, but the purity is about 95% . It's very cheap and you can still make a good black powder.

Tha analysys isn't complete in a chem style but in a gardeners style it looks to be pure enough.

 

Unless you have a better supply this looks excellent. I'd certainly be there to buy a bag.

 

The particle size and distribution looks fine for storage but it will need milling before use. Mill some to pass 200mesh and you should do well.

Ok, awesome. I'll have to hop over with a friend who has a car and pick some up. I could do it with my motorcycle, but I doubt strapping a 50lb bag to the back would be a good idea.

 

Thank you guys.

A LARGE part of being a sensible pyro person is not to get noticed for the wrong reasons! A 50lb bag on a bike could get you a traffic penalty AND noticed for what the load was!

 

They will assume either nitrate for bangs or nitrate for hydroponic narcotics.

 

Buy sensibly from a garden shop and they will assume flowers and vegetables.

I have the same bag of saltpeter, it always works fine for me.

But now i see there's also a amount of NaNO3 in it.

hehe... yeah. I can see where they might get that impression.

 

I was going to buy a bag about a week ago but local law enforcement raided a house about two doors down from me and I thought it wise to suspend my pyro activities for a while.

 

For those that are interested they confiscated roughly .5 million worth of drugs and some illegal weaponry from my neighbor.

MY "Pyro" order fron the garden supplier is part of my garden purchases, but on their mail order site people who bought KNO3 also bought sulphur! --Probably a good job they don't sell charcoal or rock tumblers!

I'm a new guy here - neat Forum! But I've messed with BP for many years, doing it the old-fashioned way, mostly as a moistened mash, dried, and screened.

 

Recently I've decided to learn how to do it right, and have been hemmoraging hard-earned $$ at a frightening rate. Anyway, to address the question, I recently decided to try an "urban" BP batch using green-lite stump-remover, flower dusting sulphur, and crappy BBQ charcoal, the real stuff, not the compressed briquettes.

 

I executed my standard moist mash BP recipe, and after a thorough drying, I was impressed. It's a long way from commercial, but it has real power, burns reasonably cleanly, and would make a nice fountain, mine, or possibly even a rocket. I doubt it'd be good enough for a lift or burst charge, but perhaps with real milling, even the impure chemicals that can be locally obtained seem to have enough purity to do a lot of good work. My guess is that those 50 lb bags are good to go for most applications. Now, where can we all get one? :D

Everything you want to know about BP is here! You just have to read it!

 

Grain size of the ingredients matters, incorporation by damp milling the mix helps.

 

Pressing and corning helps a LOT.

 

The wood type for the charcoal will show different effects the purity of the nitrate isn't usually an issue.

 

Garden potassium nitrate is the most appropriate source, perhaps not a 99,99% material but good enough and cheap enough.

Damn- I need to find a local supplier like that!!

Just do a google business search for "Chemical" "Nursery" or "Farm Supply" in your town. It'll pull up places you never knew existed and that can either help you or tell you where to go.
