you dont grow it, it is some stuff you smoke with a mixuture of chemicals like hu220 and something with 180 or around those lines. Probably will dawn on me later but you melt the chemicals onto wharever it is you want to smoke useing a crok(dont know how to spell that.) crok pot for about 3 hours and let dry all the way. You can look up how they make it. With all these k2 and afgah kuah nonsense and xxx, k4 trainwreck all this stuff is going to cause some serious side effects like brain tumors, it has already be proven to cause heart attacks.. Happy smoke this bs. When i had to quit smoking i did it cold turkey no problem for a year and a day, all the youngins need to realize when they get older that all the blunts you smoke of this crap and bongs bowls will lead to serious health problems in the future.
