Hi ,Bill. Good luck and thanks for sharing.
Me, did not , am not attempting to graft, mostly due to lack of resurces. Also my last year,s grow results were free of any root borne problems.
I,ve started my seeds 1rst of Feb. They are doing fine under light. 3 to 4 more weeks untill plant out time. In 2 to 3 weeks I will srart hardening off. At night they will sleep in the garage.
