Cant get BHO right

Hello everybody, im new to BHO and have been struggling trying to get this right. I have tried making crumble and I have tried making shatter using 30g dry cured flower and it always comes out exactly the same, so sticky you can't even touch it and it's gooey. I have tried two different varieties both come out the same so I must be doing something wrong. I have blasted into parchment paper bowl and not even touched it and it's still coming out the same after several days of purging in a vacuum chamber at 29 to 30 flipping once a day. I have tried it at different heat. Right now I'm testing some at 88° still at the same consistency and it's been 3 days. I just don't know why it's not hardening up or even turning into something other than look like shatter but sticky and gooey as hell and crumble. I can't even get at the dry up. I don't know what the hell I'm doing wrong.

@smoke and coke Im not sure how old its given to me to learn with, I know the Watermelon OG is over a year but the second stuff which I can't remember the name is not as old and is very good smoke and right now it's coming out exactly the same. I use BVV tane in a can I have a BVV bottom heater, mat and bbv 1.5 standard closed column extractor.The filter that came with is a Buna-N 100 Mesh (150 Micron) Gasket.

look up winterizing your bho. You will need to do this if you’re blasting flowers.

I use sugar leaf trim, whip it butane, two 25 micron or sometimes two 50 micron screens.
load up your tube and put it in the freezer with your butane for at least an hour.
blast then boil off. Then in a heated vacuum chamber. I don’t get the waxes from the sugar leaf that I get with flower.

@smoke and coke
  1. Do you whip it before purging?
  2. Do you use heat and purge OR purge until it settles then heat or vise versa?
  3. What is the heat setting on and does it stay that temp the entire purge?
  4. Do you flip? If so how often.

No whip
vac purge with heat to 95 degrees near the end may have to go to 100 degrees because it’s starts to harden up.
flip once or twice.
vac purge for 1 1/2 days to 2 days.

Old trim is more likely to be at least partially decarboxylated and will stay tacky.

I havent used trim its been bud only, the last stuff was actually about 3 months old from cure and it came out so tacky or sappy you cant touch it or you have a hell of a time

Old bud can be partially decarboxylated too and three months old will be. Only the carboxylic acid forms are brittle.

Retained solvents, including high terpene content will produce a soft concentrate.

I personally prefer pull and snap to shatter. It typically has more residual terpenes.

I use the temperature that the concentrates becomes liquid for purging BHO.

I place a thin film of the concentrate in a preheated oven or chamber until it liquifies and pump it down until the boiling becomes excessive, and then I hold it at that vacuum level until it calms down, before continuing to pump down to 10,000 microns/-29.5" Hg.

When I reach -29.5" without excessive boiling, I flip and repeat the above. Stop when the larger irregularly sized bubbles are gone, leaving only the fine fizzy CO2 bubbles.

@Fadedawg what temperature would that be? Also thoughts on using too much tane? What amount should be sufficient for 30g of flower?

I usually use between 100F and 115F for BHO and up to 125F for QWET. It varies with different material.

It has been a while since I open blasted, but typically use about three column volumes.

What size column are you using?

I also freeze my material and chill the butane. What temperature are you extracting at?

I am using a BVV 1.5" x 6" tri clamp spool for 30g. It supports 30g to 45g

Here is the one I use
Manufacturer: BVV
1.5" Standard Closed Column Extractor

I also freez my full column and tain for at least one to two days as well

I freeze everything for an hour or so and just do an open blast. I have some glass extraction tubes but I picked up a tube with a stand. Makes it easier to empty 3 cans of tane. Obviously I blast outside but just set it for a photo

I have tried several different times like no soak, 15 min soak, 30min soak and a 45 min soak all came out same

I tried a soak system and am not a fan, as it appears to pick up more non targeted elements, which as you note lowers the viscosity. Especially if it is allowed to defrost while soaking. Here is my test sled with vibratory assist that I abandoned.

We had our best open blast results using a simple flow through column. When LPG meets the resin, the solvent layer in immediate contact becomes partially saturated and slows down the extraction unless it is constantly replenished with fresh solvent by flow or mechanical action.

The flow keeps the partially dissolved boundary layer removed so that fresh solvent is in contact with fresh concentrate.

Unless the soaking is done in a freezer or in dry ice, it also allows the material and solvent to warm up and pick up not targeted elements like plant waxes.

Three-month-old material will be partially decarboxylated and produce a lower viscosity because THC has a lower viscosity than THCA. I suggest open blasting a small frozen sample without soaking and comparing the two.

@Fadedawg I have open blasted with no soak and I always get same results. First I freeze my tane and flower for 24+ then quickly blast into a pyrex. I blast two 420ml cans of BVV tane or Whip It tane. Once both cans are through I set the Pyrex in a warm water bath and it takes around 15 min to evaporate. I next scrape material onto parchment. I have even left some tane and poured it out to agitate it less (same results). Then i preheat my pad to 92° to get my two gallon vacuum chamber up to temp. I put it in the chamber and pull vac to -29 to -30 and sometimes it muffs up a little but never big like I see on the videos I have watched but im only working with a start material of 30g. Next, it usually flattens out into a puddle after a few hour but i wait about 12 and i flip and pull full vacuum again. I do this over a few times and a few days later i have sticky tar which is not what im after. I have tried crumble by having a heat of 115° - 125° to dry it out and still same stuff. Im confused on what the heck im doing wrong....

On a side note is that a vibrator....

If you concentrate only muffs up a little, it may be because it is already mostly decarboxylated.

Purging at 115F shouldn't take more than a couple hours. As soon as the larger multi sized solvent bubble cease.

That is a vibrator that was donated to the project, and the mechanical action helps keep the boundary layers cleared.
