Sensi Seeds is a legendary seed company founded by Ben Dronkers, which in 1975 began to cultivate medicinal marijuana. He travelled the world in search of the best cannabis. Such expeditions took him to places like the Himalayas and the Hindu Kush – all over Central and Southeast Asia.

His cross breeding programs brought some of the newest and most groundbreaking strains of marijuana to the world at large, and around this time he began to understand that the cannabis loving people of the Netherlands deserved to be able to enjoy the fruits of his works, just as much as he did. 

In 1986, Sensi Seeds opened shop in Amsterdam and quickly became quite famous, offering not only incredible strains  but also books on growing and breeding, equipment necessary to start growing.

Through years of experimentation and experience  Sensi Seeds developed some of the most groundbreaking, powerful, and easy to grow hybrid cannabis plants the world has ever seen. When it comes to the production, safe and discrete shipment, and incredible variety no other seed bank can even come close to what Senci Seeds can do.

It took me almost 5 months to write this review. I don’t know where to start from. Well, I always wanted to grow a legendary sativa like this, but I felt I wasn’t really ready to do it. I preferred to grow other strains and try new growing mediums before, and that’s exactly what I did. And because I don’t like ordinary and “easy” things, I wanted to put myself to the limits and try something really hard and never tried before (by me): growing the legendary Silver Haze from Sensi Seeds in ScrOG using a coco coir medium, filling all the grow room (1m x 1m) with one plant only. Yes, that’s what I did.

In general, I can say I’m very happy with the results, except for one thing: Advanced Nutrients. I’m sad because they burned many fan leaves on last weeks, and this because of a misunderstanding with reported dosages on bottles (which, I later discovered, are calculated following American growing standards with 1000W HPS lights). The problem is that Advanced Nutrients, with their PH-PPM perfect formula, tells you NOT to adjust PPMs of the solution because the reported value from your pen will be affected by many other components besides dissolved fertilizer in the water (eg. pH buffers, humic and fulvic acid, amino acids, etc...). They say you should start from 1/4 of the reported dosage, and increase that value a bit a bit until you reach full strength. That’s not the way I like to work, and that’s why I’ll never use their nutrients again. I’ll choose a brand of nutrients that makes you easily manage PPMs instead. But let’s talk about something happier now: the plant itself.

The hype is real here. Let’s start by saying that those burned leaves didn’t ruin any final buds. Yay! The only concern I had about this growth was linked to Silver’s flowering stretch. I didn’t know the strain, and couldn’t guess how the stretch would have been. I only knew she could become 3x bigger during the first month of bloom. But if you don’t know when she’s gonna stop, what do you do? Stop bending, without filling up all the ScrOG grid, or you keep bending, hoping she will not stop while she’s still under the grid? Hard choice. Really hard. That’s why everyone says you firstly have to know the strain, before trying ScrOG. I’ve been lucky here, and yes, I naturally opted for option B: keep bending! :laughing::+1:

The plant, as you see, is strong, and I’d say even tolerant enough to nutes. My case was a bit extreme, so maybe a skunk would have suffered too, lol. She likes topping, and reacts to it very very quickly, as well as super cropping or LST. During flowering, you can keep bending for at least 3.5/4 weeks since the day you switch to 12/12. If you do the switch and are sure that you don’t have light leaks on dark hours, you’ll start seeing pistils after one week (with temperatures similar to mine). During flowering, you don’t have to worry about size of your buds, since they’ll get A LOT bigger only on last two weeks. Believe me!

Let’s now talk about the most interesting part: buds and their effects. If you touch them, they leave you a tropical mouth watering smell on your fingers. The smell is a combination of tropical fruits like pineapple and mango, and peach. I love it. When you smoke her, you keep tasting those flavors if you vaporize at 180C, but if you increase to 200C, you don’t taste that citrus hint anymore (or maybe just a little less).

The effect is the true masterpiece of this strain. No paranoia. Couch lock is absent, but if you decide to relax on your sofa, or bed, you’ll be in the perfect location to start thinking and contemplating about your life and many many many other things. Thoughts are moving faster here. No joke. You’re creative like never before, and happy. You don’t think about problems. You like everything. And you start appreciating how nice moving slow and focusing on every little thing you do is. Wow. Almost 5 months to create this wonderful thing. I don’t think I’ll never find another strain like this. Someone tells Jack Herer could be better, who knows? But this is now my starting point on what a real sativa should be. Nice one, Sensi Seeds.

Was earthy tasting . Still got you a nice high. Buds were airy. Not very dense. Overall rating would be better a 6/10.
