I've used ILGM, I Love Growing Marijuana, a couple times, they were great because I never got my first order, contacted them before the total wait time was even up and they reshipped right away at no extra cost. The second order came in under two weeks from ... Amsterdam? I just ordered with Midweek Song in the UK, Lewis seems like a stand up guy to deal with, we'll see. I haven't used DC seed exchange yet, but have heard good news about them and interacting with them has been easy. I would recommend *staying away* from Dutch seed shop. I am only on my first grow, so I accept a large possibility of user error, but I went 0/20 on germination from them, and have 9 other seeds from Bud Aroma (Victory Seeds) and ILGM that I started at various stages, I've learned tons already, and they are doing very well...now, haha, so... Again, very sorry to hear I am the only one out of what sounds like many who have had a good dealing with them (BA), but there are tons of other options. I've learned to email a potential supplier first, get a feel for them. Even Ripper Seeds will respond timely and ship directly from Spain to the US, and they have amazing reviews, but I have not used them yet.
