Overview
Like many of the best strains on the planet, Amsterdam Haze can trace its roots back to the Netherlands. Its lineage contains Skunk, Northern Lights, and Haze, and it appears to have taken the best characteristics from each of them. This strain has been carefully bred to grow well in tough conditions, grow big, yield bigger, and provide a truly mind-expanding high.
With an 85:15 sativa-indica ratio, it produces a buzz that’s powerfully uplifting. This is a stimulating strain that will excite even the most seasoned smokers. It has a satisfying and complex flavor profile built upon foundations of tropical fruits and skunk. And its 12-14 week flowering time is impressively quick for a sativa of this size. This all makes Amsterdam Haze a strain to be reckoned with.
Strain Effects
One of Amsterdam Haze’s many headline figures is its THC content. With THC levels falling between 20-24%, this strain is insanely potent. But thanks to its heavy sativa leanings, it produces a high that’s remarkably clear-headed. The cerebral buzz comes on quickly, elevating your mood and energy levels. This is often accompanied by increased focus and heightened creativity, making Amsterdam Haze a superb strain for being productive or engaging in artistic pursuits. It’s also great for parties. Amsterdam Haze is an exceptional social strain, and its energizing nature is perfectly suited to daytime use.
The high is also long-lasting, and bodily relaxation eventually takes hold without ever becoming sedative. Therapeutically, this strain is often used to treat conditions like chronic fatigue, ADD, and depression. It can also effectively reduce the pain caused by glaucoma, migraines, and inflammation.
Growing info
Another of Amsterdam Haze’s key attributes is its yield. Plants grow to heights of around 180-220cm indoors and have been known to exceed 4.5 meters when grown outside. And with yields of roughly 450-500g/m2 inside and as large as 900g/m2 outdoors, this strain has come to be considered a phenomenal commercial crop.
If you grow it indoors, it will do well in a hydroponic setup and be ready for harvest in 12-14 weeks. Outdoors, Amsterdam Haze is good at enduring cold and mountainous climates and will flower around mid-October. It also boasts a good natural resistance to mould. This combination of stature and hardiness has earned it huge acclaim in the cannabis growing community.
Appearance and Aroma
Besides being exceedingly tall, Amsterdam Haze produces plants with many horizontal branches, and its sativa genetics show through in crops that often produce a long, bud-encrusted central cola. Buds also accumulate well on the biggest branches, contributing to the humongous yields that this strain is famed for. Topping is advised during the growing process if you really want to help your plants fulfill their potential.
Verdant buds are long, fat, and densely packed. And a profusion of thick, rust-colored pistils adds color beneath a powdery coating of white trichomes. As it grows, this strain emits a fragrance that’s typical of Haze species. An earthy, skunky undertone combines with notes of spicy pine that become more prominent throughout the flowering period
.MSNL Editors Verdict
Amsterdam Haze might be the perfect combination of potency, yield, and flavor. Experienced cultivators love it for how well it grows and its abundant harvest. Smokers love its rich flavors and its inspiring and invigorating high. We’re big fans of this one. If you have the space for it, Amsterdam Haze is certainly a strain worth trying out.

Buds of Amsterdam Haze have an earthy scent, complemented by notes of skunk and a hint of pepper. The peppery aroma grows as you break them open, and is joined by high notes of tropical fruits.
This fruity twist really intensifies in the flavor, with the taste of citrus and melon perceptible as you inhale. On exhaling, sweetness contrasts with a slight diesel tang and further hints of spiciness. Rich, smooth, and well-rounded, this makes for a satisfying smoking experience.

"100% beast "
Review by Verbal Medicine
100% germination and these things are moving way too fast. I should have waited another month before starting them did not think they would grow this fast. Not really a bad thing tho! MSNL always comes with the best beans!

Review by erick
im greatly surprise by the very little size of these seeds but they germinate very fast for me its been only one day..i must admit that i should try maybe easier strains as a noob...and first timer indoor with real genetic and "growing leds pannels" as light source...its not that i having any problem but let say i take many guess like the distance from the light to the quantity of water by numbers of days past.also add to that i only give 20/20/20 as nutrients and could be more precise when dosing.im only at half the process but to date from my noob. point of vue, it look good enough...will see at the end i guess!!

"Awesome Strain"
Review by Dewayne
I’ve grown for several years now and have recently began my own grow business now that it is legal here in my home state. Like I said I’ve got many years of growing experience and MSNL is truly awesome. I’ve ordered several times from them and I’ve grown several different strains from this company and I truly cannot remember even one seed not germinating. Their genetics are truly spectacular. I will never order from any one else. I’m a dedicated customer now.
As far as Amsterdam Haze it’s an awesome strain. I grew five of the ladies and just harvested nearly 4-1/2 pounds from the five plants. I grow indoors always and I use a SCROG. I also do super cropping and top my plants. Growing weed is like anything else in life. You get Out of it what you put into it. I grew these girls with hydroponics. The flowering period was long as it is with most sativas. I flowered them for 11-1/2 weeks and the buds were dense and beautiful. Don’t harvest to early. They put on a lot of mass the last 3 to 4 weeks. The high is awesome. It’s very uplifting and will definitely make you want to get up and do something. It will bring out the creative side of anyone. It’s a great daytime smoke. That is for damn sure. I’m a huge fan of all Haze strains. Super Silver Haze is a great smoke. I’ve got some seeds ordered now and will be growing Super Silver on my next grow.
Like I said, I’ve got more than 10 years experience growing. I’ve bought seeds from several other seed banks but I won’t ever again. I’m happy to say I’m a dedicated customer MSNL. I also grew G13 with the Amsterdam Haze and the G13 is also an awesome strain with a even longer flowering period. A full 14 weeks but worth every minute. Keep up the awesome work MSNL and I’ll be a dedicated customer for many years to come. Thanks(Posted on 01/07/2020)

"A bit forgetful, but really good"
Review by Hazy Hannah
This stuff is so hard to find, I'm so glad I finally did! Like any of the hazes, this one might make you a bit forgetful, but it's a sativa, so you won't care all that much.
