New spike discovered

I have several noId phals from the times when I had no idea about all the orchid species beyond the ones sold at the grocery stores.
They are still potted into their old clear plastic pots with old cheap Shultz bark mix, I don't fuss with them much, water every couple weeks when don't forget and surprisingly they are growing and regularly blooming.
One of them started a new spike:



Even though it is not as exciting as have some fancy novelty hybrid spiking, but still I will have some blooms and it is always nice.

Here is the plant itself:



I think probably keeping it in the basement could have helped with triggering the spike.
