Northern Lights XXL. My order # SS1031673. Used paper towel method None of these seeds germinated.

Only reason it's getting 4 stars instead of 5 is because I just recently entered flowering stage, and I dont know how its going to finish, but if she continues how she has been growing, then I will be updating this reviews to a 10star review because this girl has been growing and putting out some HUGE fan leaves, like she has something to PROVE! LOL
