I don't think there's much of a concern with ruining the genetics of marijuana. Although a species' health is measured by their biodiversity, from what I've seen there's a lot more variety with pot than say with corn. There's too much experimentation from the type of people who don't follow what...
It just causes point mutations - it changes GC base pairs to AT base pairs at the rate of 0.05 to 0.0005 mutations per gene. I'm thinking that this will allow more of the seeds to be viable if you don't have lots to throw away. But it may take just as many seeds to find a useful mutation.
Too...
You may want to try Ethyl Methanesulphonate. I saw this mentioned as a source of plant mutation. It's action is different from colchicine. EMS introduces point mutations so I'm thinking more of the seeds should be viable. I don't know about availability but would think it's available online as...
