But what seed company's version of Blueberry? I got a version from Pyramid Seeds and it was not particularly good, in fact it was not even worth keeping growing. These days there's a horde of companies that spring up, mostly in UK and Spain, where it's legal to sell seeds, who just crank out crappy seeds with the same name as strains that were good a few decades ago or bad crosses of other company's seeds, with no real breeding work done, just crossing random phenos.
You have to buy from old companies in the Netherlands and strains that won awards for those companies or you're just wasting your time and money. I know from experience, took me probably over 100 seeds from different companies to find one plant worth growing. Most of them are low resin, highly variable phenos, most with crappy bud structure. It's actually disgusting how bad the seed industry is these days. The worst part is that they charge almost as much as the real ones from Holland. Wouldn't be so bad if they were like $1 a seed or something. They just straight up cheat people for quick bucks because weed is legal to grow in many places now so there are lots of noobs who don't know any better. That plant in the photos looks like it will turn out poorly. I would start again with real seeds before wasting more time on that hempy looking stuff there. You could get lucky but by the looks of it, probably not.
Actually even some well known Holland companies have let their strains get crappy. I bought Bubble Gum from Serious Seeds, non-feminized version (thinking it was most likely to still be like the original), and it was very average, no resin on the bud leaves at all, just the calyxes, and not even that much on those. I would estimate it to be maybe 10% THC, also molded very easily and produced low yield. So apparently they let that strain go to crap.
