All you need to do is turn the knob thing and it comes off.

Could use the biscuit one if you have loads

yup safe plan

what are they made of though? What are the seals like?

I guess aluminium and basic crap seals? Perfect I reckon but take out the shit rubber seals and work from there.


game on!

ETA: best off using a coffee pot though.

There just all aluminium bud Yeah just a quick fix

Why is a coffee plunger better

It has a mesh screen for straining the fluid from the erb

I thought that was why you poured it through coffee filters though

Think the screen gets rid of any plant matter, and the coffee filter catches the spent trichs dude.

And its better it the coffee pot thing is chilled in ice water keeps the butane liquid for longer so its extrarcts more of the goodness but with longer extraction you will get a darker oil mmm reminds me the shop down the road has started to stock k2 butane after i badgered the owner for a bit mmmm see you got me wanting to do a bho run now

Or similarily you can use a thermos flask, like in this thread...

Nirex's Thermos extractor

Gunnaknow says hes left it to extract for over an hour before...

I do use the flask method i was just saying why growbag said a coffee plunger was better just put me flask in freezer

Sorry dude, It was more like info for anyone else reading.Thought that thread complimented this one a bit.

I've never even made BHO..

the butane soaks into the bud/trim,pushing the plunger down sqeezes the rest of the butane out

I always thought that the active stuff was on the outside so ne butane that had soaked into the bud/trim would just be full of chlorophyll
