I order from attitude all the time, good freebies. It’s across the pond but I have had 5 or 6 successful orders. Takes about a month to get them. Wait for the monthly promo, pay with bitcoin and you’ll end up with 20 or so freebies for $100 order.
Seedsherenow carries some exclusive strains and breeders, I have a friend that ordered from there with no problem. A little pricey, imo.
If you want some straight fire, order from ocean grown seeds. Vader and company are amazing breeders. Recommend the Jawa pie or the dark plasma. You can close your eyes and pick a strain, you will be happy. Order from lumberjack seeds, password timber. They are in the states. Regular seeds only. No fem, no auto.
A few of the bigger breeders:
DNA/reserva privada is a good one. Their skywalker is amazing. I’ve grown and smoked it more than any other strain. I’ve only grown their feminized seeds.
G13 is another Ive had great luck with, their blue og was really good and I have a blueberry gum [HASHTAG]#2[/HASHTAG] going now that smells like blueberry gum, it’s great. Also fem seeds.
Cali Connection has some good strains too, I’ve grown their Louis 13, Larry, strawberry og, all good stuff.
Favorite strains off the top of my head:
Skywalker by DNA/RP
Jawa Pie by Ocean Grown
Vanilla Kush by Barneys
Cheese by Big Buddha
Happy Hunting!
