If you have been following my main 
The first batch to get started is from https://whitewidow.rocks.
I have never grown anything from them but my buddy has and got a monster auto with one the whitewidow seeds.
The strains I got are:
Lemon drops
Durban poison
Northern lights
Skunk Cheese
Plus got a few freebies for paying in BTC
Whitewidow autos
Some extra freebies the add in when you spend so much like a roll machine, one hitter, humidity pack, pipe, and some plant tie things.
This are cool and I am glad now I get to try a few before buying any.
