Landrace Thai Sativa (Thai Stick)

Thai is a monumental landrace cannabis sativa strain known for it’s goliath size, super long flowering time, frighteningly high THC content, and of course the ‘Thai sticks’ exported from South-East Asia.

The Thai sativa plant grows vigorously, shooting up in height quick. These big plants typically outgrow the modern hybrid strain, reaching insane heights of over 12 feet easily… although taming them to produce well can be quite the challenge, especially for growers outside the tropics. Massive 13 fingered leaves are common, and when grown in higher latitudes, hermaphrodites can be problematic.

So why grow this crazy strain? Thai sativa plants, when finished correctly can present a harvest full of monster  leg-sized colas on multiple-kilo XXL yielding plants. Outdoors, these huge strains can flower all the way until January! For the skilled cultivator, landrace Thai sativa is the ultimate rewarding challenge.

Cured buds of Thai sativa strains range from smooth and sweet to exotically spicy. A specific spice smell, similar to anise, seems to be present in all phenotypes of the strain. Red tinted buds and large calyxes with a low leaf-to-bud ratio are some examples of superb phenos. A true breeding strain, many high quality modern hybrids have gotten their magical qualities from a Thai sativa parent.

You will need to make a real game-plan if you plan to finish a Thai sativa plant to harvest successfully. For growers in the tropics, this is not as complicated, as it’s already in it’s natural environment where the plant can flower for an extended time. Northern climate growers should start early and consider light deprivation techniques to induce early flowering. Finishing in a greenhouse during winter with additional lighting can help tame the dragon into producing mystical quality cannabis buds.

Big Bud

The original insane cash cropper, Big Bud touts some of the highest yields for an indica dominant hybrid of it’s type. Huge buds that gain almost too much heaviness during flowering – the branches often require staking to keep them from falling over by their own ridiculous weight.

Gaining popularity and respect since the 1980’s Big Bud was created from Afghani, Skunk #1, and Northern lights genetics, and has been preserved to this day by the Sensi Seeds company. Big Bud won first prize in 1989 at the second-ever High Times Cannabis Cup, under the mostly indica category.

A classic indica dom, Big Bud plants do not get too tall, and grow in a fat bushy structure similar to other dank indica strains. Flowering time is super fast – 58 – 70 days ’til harvest for the different phenotypes. Big Bud can be grown easily indoors or outdoors, however outdoor growers should be careful of bud mold (botrytis) close to harvest. Big Bud likes the heat and dry weather. Treat her right and get colas thicker than a human leg.

The Big Bud strain is considered a true breeding IBL (in-bred line), meaning that breeders can use the seeds to create their own generation of Big Bud, or create high-yielding hybrids. Ken’s Grand Daddy Purp is a prime example of using this high yield strain in order to pump up the normally low yields of a purple strain.

Drowsiness, red eyes, munchies are common of this herb’s mellow stone. Big Bud’s effects are the typical couch-lock indica. Sweet and musky flavors, plus the cured buds are truly BIG.
