Have not tried it. I am not set up for it and dont have the equipment. Perhaps this is a good procedure for commercial propagation but for the small grove owner and home growers it is probably not cost effective. Some procedures take all the fun of small grove owners.....old school growers like me. I do hope the procedure is expanded and made available to those that need it.
You may be right Vlad. My location allows me to graft in the fall and early winter, let them grow and force any buds as temps warm. By using the heated method folks that are unable to graft in winter may get some help.
