I was looking for sativa strains I could grow outdoors in Europe and harvest in November. I ultimately decided on Sensi Seeds' Mexican Sativa （and also grew Jamaican Pearl -- see separate review）. But of the 5 feminized Mex-Sat seeds I ordered, only 1 popped and this was after about two weeks of careful germination efforts. Canna-Seeds generously compensated for the 4 bad seeds, giving me 4 bonus sativa seeds of other strains. Thank you Canna Seeds!
My single Mex-Sat germinated around June 25. Vegetative period in July and August, and growth was slow at first. She was topped once in late August at about 50cm, and then flowering started September 1 with a stretch of about 100% to 100cm by harvest on November 6. Aroma is a wonderful fruity, citrus smell that grew more intense before harvest, but it was never too smelly to attract attention and blow my stealth grow cover.
I experienced no mold or fungus at all, and no pests. Mexican Sativa is truly easy to grow and is cold resistant as promised. While luckily this year the weather was sunny and warm all summer into October, when the temperatures cooled off significantly and even dropped to around 0 C in the weeks just before harvest, Mex-Sat was strong and healthy with no damage to the plant or buds right up to harvest. Her yield was good, about 80 grams cured.
So if conditions are right, Mexican Sativa will ripen slowly into November as they say, and I let her trichomes get at least 60% milky-cloudy, with about 10% amber. The resulting effect is uplifting and energizing. Not overpowering, the effect is a totally pleasant exhilarating energetic very clear-headed high at first, which then settles over into a relaxing feeling after a half hour or so. I've given this effect a strength of 7, which is "not too strong" （compared to the Jamican Pearl, which is a notch stronger）.
I will grow this strain again. It is right up there with my all-time favorites like Sour Diesel and Purple Maroc. Good weed!
