Outdoor weed outside Amsterdam?

[Freewheeling]

I'm going to be taking a short trip around pretty soon. Last time I was over I managed to find some nice outdoor grown buds, but it was early October. Is it likely to be much more difficult to get outdoor grown buds in early May? I will be hoping to have a call into 't Grasje in Utrecht, because that was my favourite spot on the last trip. Is there likely to be anywhere in Groningen or Zwolle that is a good bet for outdoor grown weed?
