I just had my first attempt…closed pressure colum with dewax sleeve. A bunch of shake. In a jar just pcked in dry ice to cold crash. Is this looking right?

What solvent are you using?
Yeah it’s a tricky thing keeping the cold crystals while evaping solvent. If it does dissolve it’s not the end of the world it just makes separation take a bit longer.
The amount of solvent leftover theoretically should not effect the pressure build up in the jar as the vapor pressure is only dependant on the temperature of the system. The type of solvent will however have a large impact on the vapor pressure. N-tane at room temp has a vapor pressure of around 20psi off the top of my head; compared to 120psi for propane at the same temp. These specific values may be wrong (just typing off memory), but illustrates how the type of solvent you are using will have a massive impact on the amount of pressure you will build in your diamond miner/glass jar
Hope this helps diagnose why your blowing lids off

What easier recipe do u know? Looking to make my first batch soon. Ive been making bho for some time know. Any info helps, thanks bro
U drop dry ice in your mix?
No they place the jar in cooler packed with dry ice but dry ice with 99% iso alochol is the SOP I believe. The alcohol/dry ice makes a diy cryo liquid, like liquid nitrogen… But not as cold,… Gives more surface area than just dry ice,… This step is a superficial crash and only to gather the THCa on bottom, the real crash begins when you pull it out seal,

I’m not sure what I am doing wrong any advice would help. I crashed the solvent for 3 days on dry ice. It formed on the bottom. I let evap for 2 hours at room temp then tighten the jars . I then put into oven at 85f and about 1 hour into it both lids popped. Was not sure to do so just left them in the oven . They have been in the over for over 4 hours and now almost all the butane has dissipated. Please help.
it sounds like you left too much solvent initially. then your lid popped allowing the solvent to purge after.

You could have filtered the solution cold and left those crystals behind. Appears as though you achieved freeze precipitation
So is it ruined and next time how much do I leave before I tighten the rings

Not ruined at all you just want get those huge crystals, more sugar sized pieces, put new band new lid drop temp to 80f… You was supposed to have left out room temp up to 2-4hrs lid off then lid on for another 2 but I’ve seen 4 hrs, on small batches I’ve did 2 hrs only like you did,. Did it let some the butane evaporate off before starting the cold crash? This could be it, normally I think you start that after some the tane has evaporated, I’d have to go back and check SOP but I’m pretty sure that’s it, so if you didn’t do that plus didn’t let sit out another 2 hrs at least for bigger runs with lid on before going to oven, this let’s out a lot of the tane that you would have let evaporate if you would have followed SOP exact, but it’s a lil vague anyways on couple the steps, I had to mess up my first time too…
Great thing,I don’t think it’s possible to screw up, worst can happen you only get sugar sized crystals… That’s not to bad if you ask me… Good luck bro

Ok I understand thanks a bunch

i am with you . i also get much larger stones by waiting to cold crash. .4 to .5 stones no issues

why is it ruined? You still have a jar full of THCa! Why not re-extract it into the same volume of solvent and try again (or use more solvent and recover to about 400 mL as pictured)? I would say filter off that clean, cold crash-out. Then go on to crystallize the rest of it. Use one fat chunk to seed if needed. This would be one option.
