GHS are renowned for providing it's massive consumer base with garbage, occasionally you might find something worth keeping or cloning etc, but it's quite the rarity these days. You'll find a lot of their seeds or genetics to be inferior or complete rip offs of the original strains. Such as Amnesia Haze, White Widow, White Rhino etc. I believe the reason GHS went down hill is because one of their better breeders left them, or at least that's one of the many opinions that I've read, it also seems the most viable.
If you're looking for good cheap budget seeds, try Female Seeds, I bought a 4 pack of C99 and a 4 pack of Lemon Kush from them and have had nothing but stellar results so far. Being new to growing I naturally made mistakes and messed up the germination process of 2 C99 seeds but the other two are horribly frosty and although they're not very stinky, what smell they do let off is deliciously pleasant and smells like a perfectly ripe grapefruit, the two I have seem to be the same pheno, which is fantastic as it's the Grapefruit pheno, yummy!! It's also got the most insane trichome production I've ever seen
The same applied for the Lemon Kush, I have all 4 growing, 2 in flower and 2 seedlings, the two in flower again seem to be the same pheno, or at least very similar in looks, huge amounts of pistils, strong heavy topped colas and enormous, fat dark green fan leaves. The smell, is as you'd expect, a hint of lemon with that famous Kush fuel fragrance.
I am getting to that stage where I just want to chop it for the sake of it, too much excitement for it to finish, but I am keeping strong and waiting until they're actually ready!
I hope I've given you a selection headache for what you intend to grow next, I honestly can not praise these two strains enough so far. Even the small bud of C99 that I picked off a week ago(2-3 weeks early) blew my head off. I just can't wait for the finished product
Edit; I've seen that you've got G13 Labs Gigabud in your sig, how is that? I've been looking at that one for a while(purely for the name haha) but not seen many reviews or anything. Could you shed some light on what it's like/how it's growing? Thanks.
