I am going to try grafting again tomorrow. I have a very strong starter set up which is one place I went wrong last time. My question is how fast do I need to work? I did a little research and saw something about having to get the cell bar(s) back into the hive in 10 minutes or less? I am doing 12 cell cups on three bars and I know I'll never get these grafts done and have the frame back in the hive in 10 minutes. I'll be llucky to get a single bar done in 10 minutes. The weather will be wram but not too hot and I'll use a damp towel to cover the grafts and the humidity will be high as usual.
