Potential problems that I see with this method:
1) At the end of spraying you've got dmt-laden solvent still in your spray bottle (I've never seen a spray bottle that expels 100% of its contents)
2) Is the entire bottle and every single component piece made of HDPE? It'd be a real shame if parts of the internal mechanisms were less durable plastics.
3) How big is this bottle? Unless you're using 10 grams of dmt (making 20g of 1:1 changa) the amount of solvent is going to be so small that most HDPE spray bottles I'm familiar with are too large to be considered practical
4) I would think this method would not cause the leaf to absorb dmt, but would rather create a coating of dmt on top of your herbs, which imo, is undesirable. Soaking infuses dmt into the herbs pretty evenly
5) What's the rush? Can you really not wait for acetone to evaporate over night?
Seems like far more trouble than it's worth, imo
EDIT: As far as 10x caapi dissolving in acetone, when the acetone evaporates, the 10x caapi winds up on/in the herbs, same as with the DMT. This is the basic principle behind making changa, afaik.
