I was actually looking into m-seeds.nl a few months back. Their prices seem reasonable but my only problem with them is that they don't list the breeder of the various strains. If they added a bit more info I'd consider giving them a try, but until then I'm sticking with Attitude. I've ordered 4 times with no fancy shipping options and got what I ordered each time in under a week. Only ever have one seed from them not germinate, which was a freebie seed. I've ordered once from Nirvana, but I'm a little skeptical on the genetics. I order their Northern Lights and it is growing well but looks like a mutant plant. Hard to explain. Some of the fan leaves are missing "fingers" and some look mutated. It's just begining to flower now, so we'll see how the smoke is soon or if it goes hermie.
