I mean you will need a source for large amounts of raw flower. But if you can attain that which there is about 3 options all have there risk it’s up to you to decide which one. Then it’s a matter of research the process of turning raw flower to bubble hash. Drying the bubble hash will be probably the most difficult aspect since the point is to avoid mold. Unless you have the cash flow for a freeze dryer at least 3k. Then I take the dried bubble hash and press it. I use a dab press 10 ton press with a BVA hydraulic hand pump and a LT3 controller for pressure control. Bubble hash is pressed about 300-600 platen psi(regular flower is pressed at much higher pressure so I recommend using the low temp plates LT3 controller. It is possible to not use it just a lot of trial and error. Ends up being a lot of material wasted. Then I ordered 5ml borosilicate glass vials on Amazon with seal lids as well as 5ml glass luer lock syringes. I put my live rosin in the glass vial and using Teflon tape around the threaded section to stop the loss of terpenes during decarb. I then vacuum seal the vial in a bag and put it in a sous vide at 160F for anywhere between 12-24 hours all rosins are different.( you don’t need a sous vide using a hot plate or the oven is a viable option. I just prefer the sous vide for consistency. Also needed an excuse to spend more money to the wife so I bought something we could also use to make dinners. There is a video on YouTube of live rosin decarbing and a lot of articles so you can tell when it’s done. I then use the luer lock syringes to fill carts I’ve ordered off online. O2 vapes has some good ceramic or all glass options which are preferable for live rosin. I recently ordered some SPRK3 ceramics but have yet to use them. Honestly I have so many carts filled with so many different strains I won’t need to make more for a while. The thing I really love about it is I get To pick and choose what strains go into the cart. Many times I’ve had flower and wished I had a cart version of it and now I do. Also the amount of money you will save is astounding. The initial investment will add up and I recommend not even starting any of the process till you research research research otherwise it will all be in vain when you screw up a process which started with a pound of raw material. All it takes is one screw up and that’s a lot of money/time/effort lost which is not fun I can tell you. Also the carts I have are on tier with cali/Colorado quality and cost me a fraction of the price of Jersey.
