White Widow XTRM. This strain is among the strongest weed in the world. Molds and caterpillars tend to shun away from attacking the White Widow Extreme strain, thanks to her stability. She is fibrous enough to repel most of the cannabis predators, and her strength extends to the fact that strong winds rarely have any adverse effects on the plant. 

As is the case with her regular mother, White Widow, the White Widow XTRM feminized maintains the physical attributes of her mother, and this includes her standing out white trichomes. The buds are also massive and it shouldn’t be surprising you to find that she can yield to as much as 500gms per square meter when cultivated indoors, and up to 725gms per square meter in the case of an outdoor growing. 


Born and bred here in Amsterdam. Although many countries claim to have created White Widow, we can state the fact that here in Amsterdam White Widow first saw the lights. This weed has won more cups than any other strain before. On the top of all Dutch coffee shop menu's (mostly the most expensive!)

We can, however, say that the weed cafés are justified to sell her at such higher prices, as White Widow Extreme is a deliverer. This weed strain from the world’s marijuana capital – Amsterdam, is the ultimate definition of elegance.


A must for anyone who thinks they are a smoker!! White Widow XTRM is a very strong plant and can grow anywhere. This great Indica hybrid packs a power punch. The buds have so much THC on them that it is hard to see the bud at all. White Widow is the most popular white strain, the buds can be completely white covered in nice sticky resin crystals. The high is extreme and the taste divine.

Her THC-filled buds harbor as much as up to 20-30% of THC, with the average under most circumstances being up to 24%. Necessarily, the White Widow Extreme strain is the best for that pothead who likes a nice after-dinner potent hit of dope. Our customers reach out to us while smiling and tell us that this is the real deal for combatting nighttime conditions such as insomnia and exhaustion. The high is mostly smooth, and with no couch-locked effects. 

White Widow XTRM! Smoking White Widow gives you an outer space psychedelic high. White Widow XTRM sends you to the Andromeda galaxy and beyond.


Even inexperienced growers can successfully grow a crop, White Widow XTRM can grow anywhere. Never tried growing a plant before? Read our Grow Guide and try. 

That said, it isn’t daunting to cultivate own White Widow Extreme as her growing difficulty is moderate. If you are inexperienced, but you are not an absolute beginner, then, oh yes, you can try germinating your White Widow XTRM seeds. If that seems like daunting, please go through our germination guide, and you will have started getting your feet wet. 

As earlier on stated, White Widow Extreme is sturdy and she tends to have this pride that she is an island. She likes her space, and keeping her near other strains would be doing her a disservice. It would be best if you subject her to sufficient spacing, if at all, you would love her to make you happy by unleashing her monstrous yielding potential. 

You also need to provide her with sufficient nutrients, and coffee grounds would be a good way to provide her with organic nutrients. You may also opt to supplement the coffee grounds with artificial marijuana fertilizers since she may absorb the nutrients faster than fathomed. 

Please note that we advise the grower to germinate these beans at the onset of the fall season, and it would be best if you order your ganja seeds well in advance to avoid any uncertainties that may come your way probably due to issues to do with delays or the need for replacements. 


Perhaps you are here since you have heard the praises attributed to the standing out quality of our marijuana seeds, and we can’t edge out talking the fact that the White Widow XTRM seeds are of the same top-notch quality. One of our customers stunned us with their review, “Finally, my search is over. I have been searching for the best White Widow XTRM feminized weeds, and those that I found gave rise to weaklings. Thankfully at AMS, I have gotten seeds that walk the talk – stability at its best. AMS is a keeps for me.”

We have a profound feeling that you will be the next on the line to review how fantastic our White Widow feminized strain is such a beauty to behold. It’s straightforward…

Order our more powerful strain White Widow XTRM. This cannabis seed is available as regular, auto-flowering and feminized. White Widow XTRM is the best and strongest White Widow strain available, so beware first-time smokers! You have been warned!

Monsters Review by Cyril (Posted on 6/24/2021)
These seeds grow into monsters. I popped 5 seeds and they grew fast but with a terrible light source they got leggy really fast with just a few main tops. I wanted to trash them at no fault of the seed of AMS but since my new seedling just popped i put them under a new LED light with epar and man it was like these plants said thank you. Now at the end of week 4F they are already toppling over with massive colas and they branched like something was chasing them from 2 main colas to over 20 tops with huge nugs. Get these seeds you will not be disappointed the smell is a mixture of sweet and floral very nice.

4 stars: good service, well treated Review by Jen (Posted on 3/25/2021)
The beans took about 3 weeks to get to Canada which is what they inform so that was good. I popped 2 WW XTRM and both germinated quickly. I am just watching them pop up this week. Also it was very discreet
5 stars: perfect, definitely recommended Review by KPierre (Posted on 3/25/2021)
I am currently growing a batch of White Widow extreme. I germinated four seeds and all four seeds germinated! I am just about to enter the flowering stage and you should see how healthy these plants look...they look like they could be from a magazine article on what elite weed should look like. So, so healthy looking and a nice shade of green. My future purchases will only be from AMS!
5 stars: perfect, definitely recommended Review by Chris (Posted on 3/25/2021)
I ordered the White Widow XTRM seeds and they arrived about two weeks later in a plain envelope. I planted 5 of my 10 seeds and all 5 germinated within 3 days. I am now about 3 weeks in and the plants are very robust and growing very healthy under LED lights. I am very happy with the product and service form AMS. I will be ordering more seeds in the future and would recommend this company to anyone looking to purchase seeds. I can't wait for the final product.

Marc Emery brought me here Review by Marc Emery (Posted on 2/24/2021)
Gotta give the man some props. Marc Emery is the Johnny Appleseed of the grow movement in treacherous times/territory, fighting the good fight to assist in the world of what we have today. I love you Marc and oldschooler seed people! I haven't tried AMS seeds yet, but if there are any issues, I'm sure it will be my fault :D
I would recommend using their services. Review by Darrell Davis (Posted on 2/18/2021)
Shipping was an issue difficult to get the first shipment. Emailed them told him I never received the package they re-mailed another package which I did receive. The only reason I give it a four star is because it was difficult to receive the package. I would recommend using their services. I purchased the white widow extreme feminized. So they’re growing now there about 3 inches tall.
