Yumboldt Strain Review – Bonza Blog

Yumboldt is one of the strains with great mystery. No direct information can be said about its history except that its parent strains might have originated from the Himalayans in Afghanistan. Supposedly, these indigenous varieties were Afghani and Himalayan which found its way to Humboldt County, California by the late 70s.

Almost two decades later, it found its way to Sagarmatha Seeds who decided to cultivate it in Dutch lands. In Holland, the breeders perfected its effects and propagated its genes before submitting it to the High Times Cannabis Cup in 2001 where it bagged the title of “Best Indica.” Samples from the strain exhibited similar characteristics to the original landrace cross from the farms of California that users smoked heavily in the early 80s. It was aptly called ‘Yumboldt’ afterward.

However, those who have tried it say the effects leave one in a happy, contented mood while tranquilizing the body at the same time. Its heavy sedation wraps up its psychoactive high like a one-way ticket to dreamland.

Odor and Flavors

Yumboldt’s aroma often comes as a pleasant surprise. It welcoming aroma is a pungent earth similar to how it would smell right after drizzle hits soil. Combusting it releases its distinct fragrance of sweet lemon juice which translates into the palate as a refreshing zing on the tongue. The tanginess lingers long, from the first up to the last drag. On the exhale, it produces a nutty aftertaste with a hint of skunk.


Yumboldt is a rock star in the cannabis world. Its classic Indica effects take away the spotlight especially once its slow dawdling high starts to creep into the head. It takes about a full 20 minutes before its effects fully begin. Because of this, users should start with a few puffs first.

Yumboldt has great resilience that makes it adaptable to various growing conditions despite its preference for sunny California. It can withstand high levels of humidity which can cause problems like mold, mildew, and root rot. It also stands strong against heavy winds that may topple other plants or break branches lined with buds. Harvest comes around the second or third week of October up to the last few days of the month. Each plant bears up to 400 grams of buds each.

Because it has a manageable height, growers may bring it indoors where adjusting growing factors like lighting, temperature, and humidity is easy. Thinning it out is essential though. It is a bushy plant and the limited air circulation induced by the four walls can stunt its growth. With that said, it responds well to training techniques like the Sea of Green which significantly improve its yield.

During the flowering period, breeders can switch to lights with at least 400 watts. Pairing it with a hydroponics setup is also an option although soil is a more economical medium. Once full mature, it yields up to 350 grams of buds for every square meter.
