Oh, go ahead--give it a try. You've got 10 bulbs; now is a perfect time to practice a little to build your confidence. This way, when you really do have an important one to scale, it will be a lot more fun. These bulbs look OK, even with the little brown bruise spots. I'd make up a couple different batches: scales with spots, scales without spots (probably 6 of each). Make sure you treat all scales in very dilute household bleach for a few minutes and rinse thoroughly. Ask questions along the way. Oh--with summer approaching and temperatures rising, keep an eye on the temperature of your incubating samples. Keep it below 72'F if you can. And remember, when it comes to incubation, a somewhat drier media is better than a somewhat wetter media. Sound like fun?
