It's only normal if you plan to have a gazillion different crosses.
I have about 30 different pollen parents right now and some of those pollens only go on 1, maybe 2 pod parents. Sort of like Magical Marrakech, I've only used it on Leprechaun Prince so far (that may change) or Shamrock Dew has only been used on Wonders Never Cease. I just used what was open while waiting for the others to start blooming. There are the ones I use over and over and those will remain my main pollen parents. I'm waiting on a couple more to open up and that will be it as far as pollen parents. But then again if something strikes my fancy that I think will go good together then I will cross it. I'm trying to keep from having a gazillion different crosses like last year
