This is my first grow as a medical grower. I started with 20 seeds and ended up with 4 girls after throwing out the duds and all the guys. My 4 girls should be ready to harvest in 5 or 6 weeks. I have heard that it is hard to take clones from plants in full bloom. Can I partially harvest one of the 4 and then reveg it to get a mother plant going? Any suggestions? thanks,k watchit
