I let the mother plant veg out for 45 days into a nice bush and took clones mainly from the lower branches. There is some breeders out there who say that the young growth below roots better. Also I use an ez cloner 30 spot machine. I don't like cloning in cubes or those seed starter things. Here is my process for cloning and it works greater than 90% of the time.
1. Fill Ez Cloner with tap water
2. Take cuttings from newer growth
3. Sit back for 10 days and come back to roots
If you have never tried an ez cloner I feel it is worth the investment. My buddy who has been growing for years as a commercial grower said never to get an ez cloner and if I had listened to him I would probably be the guy saying the same thing.
Don't give up on her!
