Peyote Cookies is an indica-dominant plant, which is almost entirely indica, and it adapts well to pretty much any environment, making it easily one of their sturdiest strains.

Sativa cannabis strains:

Amnesia

Haze strains are known for being highly resistant to humid environments thanks to its open flower structure. In this case, Amnesia 100% Fem is a great choice as a sativa strain to be grown in rainy, high humidity levels, even though it’s ready to harvest in October outdoors.

Amnesia 100% Feminized is an 80% sativa strain that has been crossed with an Afghan in order to give it a slightly faster bloom period. This plant grows into an open structure easily, growing over 2.5m without needing much care at all. Due to being a sativa-dominant strain, its structure is a bit weaker than indicas, although this allows for more flexibility; its branches should be able to easily deal with issues such as rain and wind, however we recommend training them in order to be safe.

Gorilla Girl® by Sweet Seeds®

Ever since Sweet Seeds released this beauty a few years ago, it’s turned into one of the favorite strains of outdoor growers around the world thanks to the amazing results that it produces. The reasoning behind this is that Gorilla Girl comes from a combination between two of the best US strains of the last decade, and possibly in all of cannabis history; Gorilla Glue and Girl Scout Cookies phenotype called Thin Mint.

If you decide to try this strain in your outdoor crop, you’ll find that it’s a sativa-dominant plant that grows quite strong, producing an open structure and strong branches that can easily deal with bad weather and the weight of its hefty buds. When grown at the start of the season and in the ground it can easily grow up to 2.5m tall, producing almost 1kg per plant. It should be ready to harvest towards the start of October, although it should be fine when it comes to humidity as it’s naturally resistant to humidity and rot. However you’ll need to take care that caterpillars don’t get near your plants’ juice buds.

Sensi Seeds Jack Herer

Just like Durban and Amnesia, Jack Herer is another classic strain that many consider to be one of the best strains of all times. It’s a slightly delicate plant that needs a little extra care in order to produce some of the best buds you’ve ever seen.

Jack Herer is a 50/50 hybrid strain that tends to grow more like a sativa plant; its indica side helps for strong growth and allows it to deal with issues such as dry climates or low quality substrate. This strain is great for outdoors, although you’ll need to give it a helping hand by training its branches; it does well with issues such as heat and cold, as well as rainy climates. The only inconvenience regarding this strain is its long flowering period, taking until mid-October to harvest outdoors. The wait is well worth its delicious flowers.

It can adapt to pretty much any environment and easily deal with arid, cold, rainy and mild climates – it’s a great choice for guerrilla growers, although its aroma can be a bit scandalous at times.

Growing recommendations:

Hopefully, after this brief review of some of the best outdoor indica, sativa and hybrid strains, you’ll have made your mind about about what strain you want to grow this year. Keep in mind that growing cannabis outdoors requires work; none of these plants will grow successfully if simply left to their own devices from day one. We recommend regular feeding schedules, as well as organically-sourced preventive products in order to keep them insect and fungi-free; try and get products specifically for typical cannabis infestations such as spider mites, caterpillars, fusarium fungi and others.
