If you are using GM powder, you can mix it with just enough water to dissolve the powder (think thin paste) and add it at trace. Or you can add it to your cooled off lye solution.
I'm not sure about the honey powder.
Both of these additives can cause overheating due to the sugars. If you are going to try these with the room temp process (RTCP), I recommend adding them at trace.
For RTCP measure your solid oils in and liquid oils separately. Break your solid oils into small chunks, the more surface area (chunks) for the lye to come in contact with the better. Then mix your lye and while it is still very hot pour it over the solid oils. As soon as those are melted, add the liquid oils and proceed like normal. Take care to be sure you don't get false trace (if the mixture ended up too cool), or with a volcano (if the mixture ended up too hot).
