Cool,thanks for being the guinnea pig haha.I thought about trying that,but since i only have this one m-tank,if it didn't go well i would be screwed until i ordered another haha.That is my only complaint with these orchids,is that there is no good solution to using glass on them,the kayfun glass kits fit,but really kill the capacity.Now that you mention it,i just got my 4oz. of cinnamon yesterday and did notice it was in a different bottle.The orange sweet and cinnamon both came in that type of bottle,but since those 2 didn't have that little safety seal on the top,i assumed maybe they get those flavors in drums and then dispense them into bottles themselves,but being a different plastic because of reactions makes more sense.I have noticed alot of the flavors with oil,such as the orange say they may crack tanks,so that would make sense.Well hopefully your test shows no interactions,i really want to mate these together.This orchid is a beast,so pairing it with the fire & ice will make a great combo,although taking a large lung hit full of cinnamon may have me on the floor haha.I am not a cloud chaser,but i have been blowing huge clouds of almond joy from this thing,so now i want to blow some huge cinnamon clouds haha.
