I know you can get Tangerine Dream through The Single Seed Center, I'm not sure about the SLH though. Attitude might carry these in their Pick & Mix section. I just got my Tangerine Dream a couple weeks ago, but I won't be running that strain for awhile yet, probably. Good luck on your grow!
Attitudes pick and mix has them, but the Barneys Farm is out of stock at the moment. But the single seed centre has both in stock
