PF Tek help!!

I am trying my hand at growing some Alkabenzi Cubes and am worried sick... It's been 4 days since inoculation and I have yet to see even the tiniest of mycellium. I'm keeping them at roughly 80 degrees and exposed to a small incandescent light for most of the day. I only waited three hours after steaming in a hot water bath before inoc, so maybe I killed the spores? Any ideas would be appreciated. Thanks!
