Grow organic read bottom of page

Pot that has been fertilized right up to harvest is harsh to smoke, sometimes the joint will even sizzle and pop as unmetabolized fertilizer salts combust. Un-flushed pot leaves black ash, is hard to keep lit and burns your throat. Pot which has been organically grown and properly flushed is more flavourful and fragrant, burns easily, leaves grey ash, is easier on the throat and is much more pleasurable to smoke.

seems your wrong... again
