The first signs of physical root growth that are obvious to the naked eye consist of tiny nodules of goodness commonly referred to as calluses. These white bumps are a tell tale sign that roots are coming and that the first major step in cloning has been achieved. For all of the negative signs that a clone can present that something in the process is going astray, the calluses are a welcomed sight to those that have patiently been waiting for any indication that they are doing something correct.
A couple thing to remember here:
- Callusing varies in length of time. Some plants may show sign within 48 hours while other can take several weeks before a hint of root development occurs.Â
- Calluses do not equate to cloning success.Â While the appearance of calluses is certainly a good sign, the clone is still very vulnerable at this stage and things can change in a hurry.Â
So, while the emergence of our friendly white bumps is cause for joy, keep the party hats and streamers hidden away for now. The same good practices that are recommended to bring about the emergence of calluses still apply for developing those calluses into healthy white root structures. Instead of a celebration, a good pat on the back will suffice as you receive your first bit of good news from your new baby clones.
