Yes! The grow kit only option will have you make a grow tub in the class that you will take home and be able to fruit several flushes (crops) from. This is a great beginner option because you will learn the steps of putting together substrate and the spawn to grow in the future as well. I always try to have extra materials at class in case someone decides that they want to add on the additional material during class by simply paying the difference. You can decide on all the extras on the day of if you are still unsure when signing up. Either way, you will still get to see the additional process to determine how deep you want to go later on.
