Have had no dealings with them, so no idea of their legitimacy but a quick google provided some links on others perspective with em.

their seed prices are average, they also sell royal queen seeds on their site and one other brand, weird partnership. RQS rep James is on the site, maybe ask him if they know of them being an official reseller for RQS, might shed some light on them.
They have only been around since 2023 and have a massive catalog so something is up. You don't just enter the game and have that much out of no where. Likely just reselling white label seeds bred from a bigger wholesaler who just brands the product for them.
I would not expect great thing from them. They also list a entire section of THCA seeds and this is a bit redundant as all THC heavy strain are already THCA.... the A stand for acid, and its a stable precursor cannabinoid to anything like CBG CBC CBN THC even the fancier things like THCv or CBDv all have acid forms. akak THCA/CBDA/CBNA/CBGA/THCvA and CBDvA, When heat is applied the acid part gets removed and turn into CO2, this process is called decarboxylation. Its why you can't just eat weed and get high, you need to smoke it or heat it up to break that chain to become bioactive and psychedelic. So for the company to say it has a special line up of THCA seeds is sketchy and weird marketing playing on the dumbfounded.
They also list a Certificate of Analysis for the plants, but the results are only done on the seeds. to show they do not contain any THC or CBD. No real testing data it seems. The reddit review are special, maybe unauthentic.
