What does percentages mean on a oil smell

How do you know how much percentage to use? Is it a hit and miss?

This has been answered for you several times if you read through the responses.

The percentage is the safe usage rate provided by the FO supplier.

Your mp should say how much FO to use, its usually 2-3% for mp.

How do you know how much percentage to use? Is it a hit and miss? I dont want to waste 1/2 a container of i gradients only to find you can barely smell anything.
Thanks for the heads up on the Hawaiian smoothie btw! I was trying to figure out where to get his list.

The only way you will know is trial and error. Same way we all learned what works best in our formulas. It will also vary from FO to FO. So testing is the only way to find out. the advantage to MP is you can always melt it again and add more.
