Have a good time playing with that ;-)
Microbiology is fun but bit too time consuming, I like it but it's not for everyone.
Btw if you want to make your own agar plates I have good results with classic agar with wort, it has to be ~8°Bx and don't need any more nutrients added. I still have some left in jars that got through pressure cooker.

Yes it can be split somehow, but if you have to do lot of samples it can get quite long even at home.
I stored few strains of yeasts in fridge and when I had to reinoculate them on fresh plates to keep them alive for bit longer, I had work for few hours bit time sensitively split across 2 weeks.
