Easy liquid cultre
1 level tablespoon of spend (used) coffe grounds.
1 level teaspoon of sugar (brown preferably)
1 cup of boiled water...
Mix and let stand for 30 minutes.
Filter through coffee filter to remove particles. Add 2 more cups of boiled water.
Put in jar with some broken glass pieces. jar lid needs two holes sealed with silicon.
when you eventualy take stuff out of the jar you use two syringes, one in each "port".
One syringe is packed with cotton wool, air would pass through this to fill the vacuum as you suck liquid out through the other syringe, keeping airbased contaminants out.
Presure cook for 45 minutes... let cool and and put something in...
And no, you don;t need to buy new stuff... you can make clone cultres as explained above with the LC. or you can take spore prints and make your own syringes... Clones are definately the way to go, as they perform much better, and give nice even flush canopies.
