I've been shopping there since 2001 and it's still among the best growshops in A'dam. Their seed selection is a mix of cutting edge new genetics and the older classics, as well. The staff is always knowledgeable and can help point you in the right direction. I couldn't believe how much he knew about the strains I've been currently using. He even pointed out an important detail that really hadn't dawned on me, though I'd grown that variety 3 times. That's helpful! They no longer offer a 10% discount to people that visit Cannabis College, though. In the past, I always went to CC first, then crossed the canal to Flying Dutchmen and got a discount. Still among the best and not to be missed.

After seeing the Flying Dutchmen's "Pot of Gold" strain grow in the Cannabis
College I decided to buy seeds of this beautiful strain. I bought a pack of
the seeds at the Flying Dutchmen seed company across the canal from the
Cannabis College. The help there was very informative, they also helped me
pick out a variety that does very well outdoors here in Dublin; "Haley's
Comet". Because I had visited the Cannabis College garden they gave me a 10%
discount on the seeds I bought. They also have the most beautiful collection
of handblown glass pipes I have ever seen, well worth a visit!
