Greenhouse Seed Review 2021

By James Alexander – Updated 26 February 2021

green house seed review

Greenhouse Seeds Review: Greenhouse seeds have a unique strain selection, but unfortunately, that’s the only unique thing about them. With no shipping to the U.S. and Canada, limited payment options, and lower than average shipping times, Greenhouse Seeds does little to stand out amongst the competition. Unless you’re hunting for one of their specific unique strains, I can’t recommend Greenhouse Seeds.

ILGM provides better customer service and fast shipping to the USA, while Weed Seeds Express has a better strain selection and cheaper prices.

Who is greenhouse seeds for?

The founders of Greenhouse seeds are known for personally traveling across the globe in search of landrace strains.

Those looking for these strains will be happy with what greenhouse seeds have to offer.

Who Is Greenhouse seeds Not For?

Honestly, unless you’re specifically looking for one of Greenhouse Seeds’ unique strains then there are plenty of better options online.

If you’re in Canada, Seedsman has a massive selection and cheap shipping.

If you’re a U.S. customer, ILGM offers free shipping as well as a larger strain selection than Greenhouse seeds.

Seed Quality 4/5

Some users report issues with getting all of their seeds to germinate, though the quality of the plant is top shelf.

Strain Selection 4/5

Though limited in number, Greenhouse Seeds offer a unique selection of strains, which could be good or bad depending on what you’re looking for.

The founders are known for traveling the globe looking for unique strains, though if you’re looking for the more popular ones you likely will have a tough time finding them here.

They offer CBD, auto-flowering, and feminized seeds.

Customer Service 3/5

Customer service with seed banks is always important to me and Greenhouse Seeds doesn’t have the best reputation for their customer service.

They have no germination guarantee, instead offering very specific instructions on their website for germination.

If a customer has issues with germination and did not follow the instructions exactly, then Greenhouse Seeds will often cite “user error” as the culprit and offer no replacement or refund.

Customer Reviews ⅕

I was curious as to why Greenhouse Seeds doesn’t offer any sort of customer reviews on their site and after digging a bit online it’s easy to see why.

Though the products they put out seem to be at least half-decent, a quick look on Reddit reveals that Greenhouse Seeds is almost universally disliked in the growing community.

While their “about us” section brags about their dedication to traveling the world looking for their unique strain line up, it seems they have some unethical business practices in obtaining these strains.

Even the more dedicated strain hunters seem to avoid Greenhouse Seeds for that reason.

Payment Methods 3/5

Greenhouse seeds lose more points with me here as they offer fewer payment options than most seedbanks.

They offer direct banking, bank transfer, cash in an envelope (Euro Only), and Credit Card.

If you’re looking to use Bitcoin I would recommend seedsman, as they ship worldwide as well as offer a 10% bitcoin discount.

Shipping 2/5

Greenhouse Seeds ship almost everywhere (UK, EU, AUS, NZ), however, they do not ship to the U.S. and Canada.

If you’re in Canada I recommend seedsman for cheap and fast shipments, and ILGM for those living in the U.S.

Shipping prices are both higher than most other seedbanks in the EU with longer wait times as well, often averaging 10-15 days.

Unless you’re looking to pay extra for one of the specific strains Greenhouse Seeds offers, I would recommend Seedsman or ILGM for both cheaper and faster shipping.

Discretion 3/5

Greenhouse Seeds does offer discrete packaging for a small increase in price, which is a positive for those looking to keep the contents of their orders hidden.

As someone who likes to keep their online seed bank orders safe and anonymous, the lack of bitcoin payment options is a big minus.

They do offer cash in an envelope for a discrete form of payment, but consider they only will accept the Euro, that’s only an option for those in the EU.

Discounts & Promotions 4/5

Greenhouse Seeds has pretty regular sales so you won’t have to wait too long for a strain you’ve got your eye on to go on sale.

Greenhouse seeds also offers 3 free seeds with any purchase over £50

However, there is no loyalty program, so returning customers will not receive any sort of discount outside of the regular sales.

Greenhouse Seeds also does not accept bitcoin, so does not offer any sort of cryptocurrency discount as many other seedbanks do.

Reliability 3/5

Users have reported issues with getting all of their seeds to germinate and greenhouse seeds do not offer any sort of replacement guarantee.

Those who have had success with germination, however, have reported high-quality plants and products.

Shipping is reliable and seeds can be delivered in discrete packaging, though the shipping windows offered on the site are pretty wide, averaging 3-15 days unless you want to pay the extra cash for the fastest delivery option (1-4 days)

Greenhouse Seed FAQ’s

Where does Greenhouse Seeds ship from?

Greenhouse seeds ship out of Amsterdam, where they are based.

Where Greenhouse Seeds get it genetics?

The founder of Greenhouse Seeds, Arjan Roskam, travels the globe searching for unique strains, so the short answer is a little bit of everywhere.

Has Greenhouse Seeds won competitions?

Greenhouse Seeds has been heavily reward, with over 40 cannabis cup wins

Greenhouse Seeds – Final Thoughts

Unless you’re a hardcore strain hunter looking for something very specific and unique, I would recommend searching elsewhere for your seed purchases (have I mentioned I like ILGM?).

With poor shipping selection, bad customer service, and questionable business practices, Greenhouse seeds should be avoided by most growers.

Unless they have that one strain you’ve been looking for for years, I’d take my business elsewhere.
