I won't judge a company by 1 freebie seed, but I am not impressed by G13 Blueberry Gum. I am close to harvest and it still smells like ass in a bad way, and was fussy in veg and flower with feeding and leaves showing me slight deficiencies. Here is a day 50-something pic (taken 8 days ago).
and a link to a G13 BGum report where the guy worked his magic...or got a great seed. Wish mine looked like that.

A few days ago, Gud was talking about Dinafem OG, a new freebie released at the same time as G13 BGum. Much healthier plant for me, tons more frost, a hazey lemon smell, nice light calyx's. Here is a pic of the DFOG at the same age as the pictured G13. Going to take this one 9 weeks atleast.
Happy with both plants, but overall, I don't think I will "purchase" G13 and Dinafem stuff. Simply because there are better seeds out there. I ran these 2 as freebies to get my tent setup correctly.
Edit: 100 posts wooohooo!!! Scarhole is partially right. BGum does have a grapey smell. Grapes that have been used as butt-beads.
