Customer Reviews
Great seeds, fast shipping
I just got my order of feminized autoflowers and I'm so stoked! The packaging was super discreet, which I appreciate. Everything arrived in perfect condition and way faster than I expected, only took 4 days to get to me in California. Can't wait to get these planted. I'm definitely buying from The Seed Source again and telling all my grow buddies.
Solid genetics, good prices
My last order from The Seed Source was for some photoperiod seeds, a couple of breeder packs. They shipped out pretty quick, got here in about a week. I always like that they throw in free seeds, it's a nice bonus. The quality of the genetics has been consistently good in my experience. I'll probably be back for more soon, they have a good selection.
Good selection, shipping could improve
I ordered some high THC seeds and a few feminized strains during a sale. The product range is really impressive, they have a lot of exotic genetics that are hard to find elsewhere. My package arrived after about 8 days, which felt a bit long, though it was discreetly packaged. Everything was there and the free seeds were a nice touch. I wish tracking updates were a bit more frequent, but overall I'm satisfied with the quality of the seeds and the value. I'd definitely shop here again, just hope for quicker delivery next time.
Consistent quality, reliable service
This was my third time ordering from The Seed Source, and it was another smooth experience. I grabbed some regular seeds and a few autoflowers. Just like my previous orders, the packaging was discreet, and they always include those free seeds which is cool. Shipping took about the same time as before, roughly a week. Their customer service has been helpful when I had a question about a specific strain last year. It's why I keep coming back; I know what to expect and they deliver.
Quick order, decent price
Got some indica seeds. Payment was easy. Shipping took about 6 days. Seeds looked good. No problems.
The Seed Source Community Discussion
Share tips, ask questions & help fellow shoppers save more
Are the breeder packs actually sealed and authentic? Heard some places will repackage stuff.
Do they still do the free seeds with every order? Or is that just for specific promotions?
Hey, wondering how long shipping usually takes for you guys? I'm in California and trying to plan out my next grow.
Anyone know if you can use more than one coupon code at checkout? Like if I have a discount code and then also want to use one for free seeds.
Hey, just wondering about their return policy. If I order the wrong seeds, can I send them back?
