Bleaching powders

Yeah, but i could figure out how to properly use these bleaching powders i could make some super clean looking crude and the further process it.

Slap it into a closed loop bho with the "bleaching" chamber, boom a ton of super bho.

Basically what I'm doing. I give it more than a quick wash and use a closed system but the same idea. Basically all you need is a reaction vessel to wash it in a rotovap to purge it. and a short path or thin wiped film system if you want to take it up a notch.

You seem to know a bit about this stuff so thought I'd pick your brain about this.

A while back I used decolorizing carbon on a sample of an Qwiso wash and it made it clear like water. I have about 3 or 4 pounds of it and also a lot of keif and frozen sugar bud/trim to process and was thinking of either BHO or naphtha wash with it to get a super clean looking product.

I do everything dry and go for the d9 instead of thca. If its fresh frozen it would probably be easier to just blast it. Or maybe you could shake the tricombs off in a dry ice bag. Then You could do a sub zero wash but I'd recommend ethanol for a all around more pleasant experience. Naphtha is nasty stuff. Not sure if you can get absolute ethanol in Canada though. If you can chill everything down to-78c you won't extract much or any chlorophyll and will only need a light carbon filtration or maybe not at all

I feel bad for the kids using that and there is some still using methanol

I can get EverClear here but prefer to stay away from it as me and booze have a destructive relationship.

I have a half dozen cans of 9x filtered butane and can do a simple distillation using 2 1L flat-bottomed boiling balls so I can reuse the butane and get many times more yield compared to blasting.

I also double distill Coleman's camp stove fuel for my naphtha and can do a gal can in my DIY still in one run.

I do make a lot of dry sift and have often combined it with honey oil to make real nice black hash. Will probably make a couple oz of that as well as oil.

I have a deep freeze I use for the butane distillation but it's maybe -20C in there. I've done all sorts of extractions and have a diploma in chemistry and a couple years working as a chemist in a hazardous waste plant so pretty competent playing with all the spare goodies I get off my plants.

I'd need dry ice to get to -78C and there's no close source here.

I may just do an ISO soak then a separation with naphtha to clean it up. That's easy enough and gives good results. I'll try the carbon on a small portion to see how it goes.

Make your own dry ice with your co2 tank. Make a cooling bath with dry ice and acetone. Gotta get it to-78c to get a nice clear yellow raw extract whatever solvent you are using. So I say may as well use something that is not denatured but I understand your issue so maybe it is best to stay away. It would be tempting I'd think. I don't drink at all ever but I enjoy the smell of absolute. Especially when their is oils suspended in it. It would be tempting for some people to just drink the tincture

I don't have a CO2 tank. I do but it's empty and I can't get it refilled as it's kinda not legit.

I can make pretty decent oil so not too worried about fussing around that much. The locals here are basic country stoners and think it's top shelf stuff as it is.

I was in Toronto a few weeks ago. Visited a couple shops. I was really impressed with the experience and how the retail shops are setup. Kinda reminds me of shopping at best buy or the apple store. A little different than what we have where you are let into a small room to make your selection then pushed out the door quickly as possible. I was disappointed in the flower selection and quality. The most potent stuff I could find was only 22% . The cannabis solmulet I was with thought that to be impressive. I thought it funny. Most strains were less than 20%. And no infused eddibles or tinctures. Apparently pending legislation. This all got me wondering what other resources you all have available for growing and processing. I didn't see a grow store every 4 blocks like we have in Michigan. Can you get co2 tanks?

Oh and the packaging. Lol impressive but talk about over kill and wasteful . Even if you just buy a gram it comes packed in a sealed box about the size of a shoe box with a 2nd box inside that and the flowers were inside a ceramic jar. Nice heavy jar, but I hope they are recycling all this junk

Here it is

We can get CO2 tanks no problem but need to rent the tank and open an account.

I haven't had to buy pot for 30 years so never plan to buy gov't schwag. Stupid shit that's supposed to shut down the black market. My ass. lol

You can recycle but there's a time limit and has to go back to the same store. Each province is in control of how it is retailed and edibles are coming out in Dec. Limit of 10mg per serving so one 10mg cookie or 10 - 1mg ones in a single package. Gonna kill the BM for sure!

It's all a big corporate takeover of the black market. They recently changed the rules so micro-growers have to have all the same shit as the big players which basically shuts down free enterprise and competition.

No sweat off my balls so fug 'em all.

They won't be taking over anything until they step up their game. And they will but it'll take time.I was like, you want me to run home real quick and get you some actually good bud?. Lol I almost brought my own as I always do but I thought nahh I'll play by the rules and just buy it there. The strain in that box was called house plant.lol really? Thats what you came up with? House plant? Thats your top shelf flower? House plant. Ooooook.
Actually it was appropriate name it smelled and tasted like house plant. Can I have a terpene or 2 please?lol.
Give it time though to work everything out and I imagine they will give the black market a run for their money. They certainly have the resources and support. It was like that here at first. Dispensaries weren't very popular and had a bad reputation for poor overpriced product. But things changed and it seems many people trust and patronize the retail shops more than their caretakers/growers. Even if it does cost a little more, it's more convenient and they offer a very wide selection and have the product knowledge that most caregivers don't have. Most big ones here offer about 30 or more kinds of flower and have other products and brands many people don't know existed. Like who knew they had weed gum.lol . In many cases Their grower only knows so much and doesn't know it all and only sells flowers or occasionally hash and oil.so when they walk into a dispensary for the first time they are impressed and realize their dealer really doesn't know shit. Even so there is a part of the population that still think their caregiver is the only one they trust and don't care for all the fancy retail products and overwhelming selection. And some still enjoy actually sitting and visiting with their caregiver for a while and aren't looking for the quick in and out convince of a store

It'll be a cold day in hell before I buy gov't approved pot.

The gov't has 'approved' about 18 different pesticides and fungicides for these guys to use based on the GRAF, (Generally Regarded As Safe), ratings for use on fruit and veg. When was the last time you smoked a tomato? The residue chemicals can change when combusted and they don't have a clue yet what the long term effects will have on consumers.

The whole premise the LPs, (Legal Providers), have based their prices and stocks on are prohibition prices from 10 years back. They can produce bud for $1g or less so it's a huge markup compared to say, liquor. If the same was applied to alcohol there would be a lot more bootleggers around and a lot more people would be brewing their own and setting up stills.

It was a couple years before the law changes that I was ranting about the proposed rules. It's not legalization but Prohibition 2.0 designed to protect the big money guys that set up the legal grows under our previous Conservative gov't. Most are owned or headed by the same gov't pricks that fought us tooth and nail for years. Hypocrites, the lot of them and a pox on their houses!

When I was out in BC three years ago I went to my first dispensary in Kelowna and bought a gram each of 5 different strains to try them out. Meh. Only one impressed me and it was a hi-CBD one so I bought 10g of it to bring home to make my cocobudder out of. Best medicine ever for both my arthritis and depression. Trying to grow something similar. It was called Sweet Skunk CBD made from a cross of Island Sweet Skunk and an unknown CBD strain. It had been lab tested at 12%CBD and 7%THC.

Atm I'm growing a cross of the ISS and DJ Short's Blueberry that I want to cross with another hi-CBD strain flowering with it called Sebring's Revenge that is supposed to be around 20%CBD and 2 -3%THC. Day 24 of 12/12 now and all looking good. The ISS are regulars but I got 4 girls from the 4 I planted and the Sebring's are fem so I'm going to have to resex one or both to get my cross so will be making the chems I need to make STS. I could sprout out more of the ISS to find a good male or two but want to have a go at making fem seeds.

I have 3 different kush strains and an AK47 in there as well to make lots of crosses focusing on getting CBD into them. Some fave sativa strains I need to sprout to get CBD into them as well. Winters are long here so plenty to do.

I know. Heard it lots of times. All people repeating what they heard without trying. Its always "I heard" never "I tried failed and tried again "
It has Not been my experience (loosing cannabinoids) but, I'm just me. But I'm not sure what perpetuates this, "I heard "
Lol however I suppose it does draw people into the crc seminars and sells a variety of polishing products.
But hey, why should the answer be so simple right?

Yes I've filtered using activated charcoal, and it removed the contaminants I was trying to remove, along with some of the THC.

What perpetuates the story, is people who've actually tried it, reporting their experience.

Another way to consider it is Occam's razor. If it was as simple as the activated charcoal filtration detailed in the late 60's and early 70's publications, why has anyone looked any further?

Hey what's going on guys, so the guys over at future4200 are confusing the living shit out of me and I'm trying to figure out how to use these bleaching powders correctly.... from what I understand you're supposed to make sort of a layer cake and then put it into the closed-loop system and blast through the layer cake but I I have no idea what I'm talking about and if somebody could please help me learn what I'm talking about I would greatly appreciate it.

Don't feel bad, the post was to stir up business, not educate you as to intimate details.

What they've done is weld a sintered stainless filter disc in the bottom of a stainless column, and packed the first 75% of its length (4.5") with T-5 colloidal silica, another 12% (0.72") with Magnesol filter powder, and topped off with 12% (0.72") Silica gel 200, 400 mesh.

They say they use a 20 ton press to pack it evenly, but my guess is that the full 20 tons isn't required. Their point about channeling is valid, so it needs to be packed evenly as you load it, not loaded and then pressed.

They note a media retention device, which I read as another sintered filter plate on top.

No mention of back pressure, which will determine where it might be used. They mention it works better as a recirculating filter than a single pass. I'm pretty sure that is correct as well, and how I would use it.

That's refreshing to hear someone say they actually tried . Im not exaggerating when I say once a week someone says "i heard" and when i ask where they dont know and if they tried it's almost always no. I heard people refer to the old text from the 60's and of course cannabis alchemy. Some stuff I have seen describes using gravity filtration which wouldn't work well. Also seen using wrong mesh and wrong source
Did you try again a different way? What carbon source and mesh did you use ? What did you use as a filter aid? Did you do hot or cold filter?
Do you have the paper you wrote on it and the test results and numbers to share?

It wasn't subtle, and we wouldn't be having this conversation if you too had actual personal experience.

You are the one preaching against the gospel, and the one the onus lies on to disprove it. I'm just here to keep things in perspective for the rest of the readers whom you may be influencing with your statements.

Instead of you picking mine apart, you present the perfect process, and I invite the rest of the forum to try it and see if they end up with less cannabinoids that they started with.

Will you bet your reputation on the outcome???

Not sure about loss,but I averaged close to 4 grams of distillate running an ounce of Outdoor mids using Gws extraction and filtering process.My yields went down the older the product was.The only indoor flower Ive run was older and mostly larf.This winter I'll run some nice frosty Bodhi gear thru,just cured.Pics are of the filtering process using DE and activated hardwood charcoal.I had to mess with my numbers(grams of de,grams of carbon) but after a little trial and error I was happy with the outcome.Meaning,yielding around the same amount of distillate after each simple distillation.Makes a nice cart with no thinner or terps required.And the edibles with the oil are really nice.
