Fertile Catalyst and lavender essence oil

My blueprint "essence oil" + a blueprint on workshop. For essence oil: Red box is fuel line and green box is fertilizer. For the catalyst side: Fertilizer Inputs on are the back, fuel input on the RIGHT next to the red box (Red box is just used as an indicator, don't put anything in there) The Black Box also is an indicator for the failsafe incase the cauldron recipes get messed up, you can throw a trashcan on the LEFT and have it empty out. I am at effiency 7. dont know the exact numbers for your effiency but this works.
