Top 5 Sativa Cannabis Strains: 2020 Update
Top 5 Sativa Cannabis strains are great, but their long flowering times aren’t. Here are the five best sativa-dominant autoflowers you can grow in 2020.
You may have heard about autoflowering cannabis, or perhaps you’ve grown it yourself! Autoflowers feature genetics, a wild and robust subspecies of cannabis. Ruderalis provides certain characteristics that make autoflowers ideal for growing, both indoors and outdoor Grow Gardens for Cannabis Growers.
Autoflowers don’t depend on flower like photoperiod strains do. Instead, they flower automatically after 3–4 weeks of vegetative growth. Autos also grow very fast, compact, and resilient. What’s not to love? It used to be that autoflowering strains lacked potency and flavour, but that is simply not the case today.
Aside from ruderalis, cannabis is divided into two broad categories known as indica and sativa. Although strain science is much more complex than these names indicate, indicas tend to grow shorter and stockier, and deliver relaxing, body-centric highs. Sativas, on the other hand, are known to grow tall and deliver a heady and uplifting buzz. Normally, sativas take a very long time to flower. To solve this issue, breeders have infused top sativa strains with ruderalis to create lightning-fast autoflowering varieties.
With that in mind, here is a list of the top five ruderalis sativa strains you should grow in 2020.

Quote from Subcool Himself ” I had written off this legendary strain until I came across an amazing plant discovered by Smokescreen. Found inside a bag of Dank of the few seeds found one female exhibited all the traits
of the famous wreck without producing a single male stamen even late into budding. The complex late coloring is a thing of beauty and the potency of this mother is epic. Extremely potent smoking just a few bowls is an adventure in repertory failure and flat-lining your brain waves.

5. Cheese Quake
The Cheese Quake Cannabis Seeds will give a plant that tastes, Like a Grape Cheese Danish, is amazing and we already dig this new strain. Both variations of the females are special in their own way as far as flavor is concerned. The Urkle Characters have a far more grape musty taste and the Cheese Has that unusual cheese smell,
but both of the females have the same euphoric head high combined with a body stoney Experience. I can’t wait to have this strain tested at the lab I myself get really high after smoking it. To the point it Becomes impairment and that’s unusual for us with our Tolerance Level. It’s easy to smoke and has a nice flavor but the high is much stronger than you would expect
I think Cheesequake gets me higher with more pain relief than either of its parent Strains Alone.
Cannabis Seeds Flavor
By combining the grapey-lavender taste of Purple Urkle with the unique smell and taste of Cheese we have created a flavor of Cannabis so incredible it instantly became my favorite Cheese hybrid. The inhale is a sweet Grape while the exhale is a combination of cherry and cheese. The high is strong and slightly trippy creating mental energy that can be confusing, yet delightful.
Mendo Dope Made this Plant Famous By Growing TREES outdoors in Northern California. Mold Resistant due to being acclimated to the climate.
