I've ran a few of theirs - pretty good , especially for the price, but there are so many things to try out there that I've left them in my seedbank... No major gripe here apart from most of their stuff takes 70-80+ days. With all of the shorter photoperiod stuff out there...it makes it hard to want to go back to.
GG4xGG4 S1 was super easy , very strong grower and is my go-to daytime smoke right now. Great euphoric "get shit done" sort of high. She was a strong producer, needed heavy nutes, and went 75 days. Chocolate and some good pinene-related notes on the exhale.
Dawg Biscuits was a beast to grow; not only in size (she filled damn near half of the 5x5) but was a super-touchy and demanding lady. Lovely smells, good stacking but not tons of resin (maybe my fault). Cured up nicely and stinks like a skunky gas cookie or something. Translation to taste isn't as strong though but a good mid-day/late-day smoke. Not too couch-slapping, per se. She took 76 days... I had the oddest foxtail herm thing happen with her - on one cola - around day 60 - it was crazy. Essentially a super-fast-growing foxtail that then started spewing nanners. Once removed, no other recurrences. I still don't know wtf that was...?!
Purple Cake was pretty strong and easy to grow but she never lived up to her name; no purple anywhere! Maybe the pheno I grew pulled some recessives out but she wound up smelling slightly lemony and sweet. Not really too tasty or smelly but with a super-strong couchslapper of a high. Great bedtime smoke. I pulled her at 76 days but she could have gone 80+ for sure.
In a subsequent run, I grabbed a "tester" pack of Gooey Glue and had a beast of a plant going...but had to chop her (sadly) when she started throwing balls and nanners around day 17. Too many to try to manage for that run. She had a nice smell (via stem rubs) that was somewhat piney and sweet. I left their (GSP) discord before hearing how the smoke ended up but I'd suggest some caution with that one (or perhaps I screwed her up , which is more likely).
In summary, seems like decent stuff but there are a lot of fish in the cannabis ocean. Time is your limiting factor; best of luck!
