What are some tips for indoor tannning?

Im 14 and I love in New Jersey, Its the first day of Spring and im home right now, because i got a call this morning that i have a snow day. Because of this ridiculous weather here, was forced to sign up for a membership at "California Tanning". So, I have only gone twice, and the tan is starting to show up, but i want to make sure i get a nice even tan. Any tips? ( I use "Seductive Black Hemp Indoor Tanning Lotion )
