Kymboed, a clone is an exact copy of the plant it was taken from. Nothing is lost in the cloning process. The only bit of truth to what GreenLeaf420 is saying is that over the course of hundreds of clone generations some genetic degradation can occur. But it's hard to imagine an amateur grower encountering that problem.

There are other factors that can attribute to clones losing their vigor, but if the plants are healthy then something else is contributing to the perceived lack of potency.
Orzy Reviewed by Orzy on . Clone longetivity I was wondering if you keep taking clones from the same line all the time if the strain gets weaker as you go. Do you have to refresh the strain or will it keep on producing? A mate of mine constantly grows , he has 3 rooms, 1 clones, 1 veg and 1 flower. Every 8 weeks he has a harvest. Just before he puts them into his flower room he takes clones off them. He has been wondering as he seems to think the strain is getting weaker and every now and then a harvest is no good, it looks ok but Rating: 5
