Mine is still "sleeping" in the garage, but if mine would start spiking now-
You say it is only four inches tall now, so it has a few weeks to go until it blooms. I assume you say it must be blooming outside because of the stench.
How about placing it growing in a pot outside during the warm days and bring it into the garage in the evening, until it gets warmer.
I find the stench is only present for a couple of days.
