I think if a clone was cut with enough moisture and placed in an airtight seal within a jar the clone could only die from possible suffocation from oxygen deprivation or just too long. If a clone doesn't dry out and stays green it should live for a long time if kept at the correct temperature. Is this correct? I dont even think the unrooted clone would use up very much oxygen or produce much CO2. What is the average life of an unrooted clone and how much oxgen will they use in their airtight container? Zandor can you answer this? I think an unrooted cutting is constantly dying until the moment it forms new roots which is usually like ten days.
