Mother plant is just a term for a plant which is used to donate cuttings for clones. For many people who have space restrictions they toss out their mother plants frequently and grow out a clone as a new mother plant.

If you need a large amount of clones and have plenty of space then you would probably keep a larger "mother plant" around and not replace it as often or ever. I've heard of people having 15 year old plants, but it's not a necessity.
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
