I have found that through the years of taking cuttings. If you don't use a long light schedule,like 24 hours on. They have a tendency to take a little longer to root and longer time to transpire and wilt,eventually the will die. I've been using whatever light schedule they were on before they were cut. In my case lights are 16/8. In five to 6 days they have so many roots that the risk of transplant shock is greatly decreased. Healthier cuttings make for healthy clones. Just observations I have made through trial and error. Things like this will help others grow happy, hardy clones.:thumbsup::jointsmile:
