Another solid order from OnlyGrams!

My recent order of CBD Samen, specifically the Charlotte's Web strain, arrived quickly as usual. I've bought Autoflowering Samen from here before too, and OnlyGrams is consistently reliable. Their prices are competitive, especially when you can snag a good discount code, though I do wish some of the codes applied to the already-on-sale items more often. It's usually a pretty straightforward checkout process though, and I appreciate not having to jump through hoops like with some other seed banks. They're a solid choice for consistent quality.

Decent buy, room for improvement

I picked up some Sativa Samen and a pack of Paper und Filter. The seeds look really good quality, and the shipping was relatively fast for an international order. My only minor gripe was that the tracking update was a bit slow initially, making me wonder where my package was for a day or two. But it arrived eventually, well-packaged and discreet. Good value for what I got, just a small point on the tracking system.

Solid purchase, good support

I ordered some Premium Genetics and a Keimkit from OnlyGrams. The website was easy to navigate, and checkout was straightforward. Shipping took about 5 days to reach me in California, which was pretty decent. One of the items was slightly delayed, so I contacted their support, and they responded within a day with an update. The seeds look healthy, and the keimkit seems well-made. Overall, a positive experience and I'd consider ordering again for future projects.

Got my stuff, no issues

Yeah, so I needed some Hanfsamen and decided to check these guys out. Placed an order, and everything just showed up at my door, no fuss. Packaging was discreet, which is cool. The seeds seem fine. Pretty chill experience overall, definitely easy to deal with.

Absolutely fantastic experience!

Oh my goodness, OnlyGrams is just amazing! I got some US Genetics and they are thriving. The Fast Flowering Seeds are exactly what I needed. Everything arrived so quickly and discreetly. I'm telling all my friends about this store, and I'll definitely be back for more soon!

Consistent quality, always reliable

I've ordered from OnlyGrams several times now, and they are always consistent. This last order for Indica Samen was just as smooth as the others. The quality of the seeds and the discreet packaging are always top-notch. That's why I keep coming back, can always count on them for my indoor grow needs.

Check if it's stackable with other deals, sometimes they block that.

Mine only worked on seeds, not the fertilizer. YMMV.

Hmm, that's annoying. I'll double check the T&Cs then.

Hey, thinking about ordering some seeds. How long does shipping usually take to, say, Miami?

A Alex 1 month ago
They're based in Germany, so international shipping can take a bit. I'd factor in at least 2-3 weeks for US delivery, maybe more with customs.

M Mia 1 month ago
Yeah, what the first person said. For Germany itself it's fast, but overseas always adds time. Don't expect it in a few days.

Thinking of trying their US Genetics, specifically some Cali strains. Anyone had good luck with those from OnlyGrams?

G Greg G. 2 months ago
Absolutely! I got their Wedding Cake a few months back, and the germination rate was solid, and the plants are doing great. Really impressed.

Yep, my buddy grew out their Gorilla Glue and it was fire. Super potent. You won't be disappointed if you're into the Cali stuff.

Does OnlyGrams ship discreetly? Like, generic packaging or anything?

T Tara Patel 2 months ago
Super discreet. My package looked like any other mail, no branding or anything that would give it away.

Yeah, very plain packaging. No hints on the outside at all. You wouldn't know what's inside unless you opened it.
