Lol! i ordered exact same thing from SOS!! (tho i also got RQS Special Kush 3-pack)
I've tried a few & have the Boulder Bubblegum about 10 days from finishing. It looks amazing & so, so crystal coated! It stayed short & stocky tho was very nice & healthy all grow. It wasn't a masively vigorous grower & tho it loved consuming the nutes, it seemed to prefer bulking existing growth rather than shooting out new branches manically, so for this reason i didnt top it like normally would. But its main plus is its health & vitality - it grew 9 fingered, double serrated leaves during veg & has coated itself in loadsa really large trichs during flower. It proper looks like u just dumped a bag of sugar over it! I can't wait for it to be done & will put some pics up as well.
Sadly, as for the other freebies i tried, they were no go's. The Kandy Kush reg turned out to be male, but was the worst loss cause again it was mega healthy & strong and grew massive real quick, like an oak tree! Gutted was male. The Strawberry Fields sorta of germed but then never got past being a sproutling - never put its cotyledons out for some reason! And the 2 Cropi Canna (can't remember which 2) just never germed at all. (tho i never found many rave reviews about CC seeds, so put it down to that) And gave Double Diesel Ryder to mate who did it on his windowsill so it didnt end up doing much beyond growing!
But would do BB again, as Sagarmatha seeds always seem pretty good, plus i'm gonna deffo buy fem KK seeds next order as would love to see a strong one flowering!
And since, this post about 6 months later, have u done any of urs yet??!
