Literally do this. Put beaker on hot plate. Put raw powder in. Put ba/bb in, mix, add gso, mix. Some guys let it sit over night, some go straight to the next step.I've thought about brewing myself a lot of people say it's pretty easy but every time I look into it, it seems fairly overwhelming.
Suck it into a 60cc syringe, stick syringe in Caulking gun, put a needle in a sealed 50ml vial to vent, and another needle with the syringe filter goes on the 60cc syringe. Now slowly fill the vial.....done. Sterile and you know how it is dosed
That's a rough step by step. Check with the more experienced guys like @PurplePandaLabs Rep. @LordSamuilo and @Ickyrica for more questions
