Hand in hand, TGA Genetics and Norstar Genetics developed Grape Inferno – one of the finest strains in the cannabis industry.

As far as looks go, this strain is very attractive. It is a striking bud that boasts an amalgam of lavender, purple, and pink, signaling interested enthusiasts of its delicious flavor profile. Meanwhile, a thick coat of trichomes allude to its potency which average between 18% to 23% THC.

Besides smelling and tasting great, the herb also has favorable effects. It brings together a elating head high with a relaxing comedown that lasts throughout the day. As such, it may not be the best idea to use it in the morning or early afternoon where there is much to be done.

To develop the herb, the breeders picked strains the mysteriously elusive Nepali OG and paired it with the ever popular Querkle. The cross is undoubtedly among the most interesting too, as many had considered each to be a far cry from the other. Still, the two produced an offspring that lived up to both its distinguished fruity flavors, potency, and Indica heritage.

Adverse reactions

Grape Inferno casts a dry spell on users regardless of experience. The dry eyes and cottonmouth are due to cannabinoids interfering with the body’s natural ability to produce moisture.

Although rare, users also experience dizziness. Other symptoms of greening out like heightened anxiety and a subtle feeling of paranoia as the bud’s cannabinoids continue to stimulate the mind. This is especially for people prone to such side effects as well as users who accidentally over indulge on the strain.

Because of its compact structure, moisture gets stuck easily in between its crevices. As such, it will need to be thinned down by pruning the top to ensure an even canopy. This will also encourage bud growth while ensuring proper air, light, and nutrient distribution.

With that said, Grape Inferno is not at all a tricky plant to cultivate. It is sturdy enough to withstand various unpredictable factors such as strong gusts of wind or sudden changes in weather. And, although it prefers a warm environment, it has no problem adjusting to the cooler environment of the northern hemisphere.

Soil mediums, especially one that users nutrient-packed super soil, remains superior when it comes to setups. Although, one may still opt for soilless ones such as hydro or aero in developing the plant to its full potential. Moreover, such techniques use less chemicals like pesticides.

As alluded to earlier, Grape Inferno produces small circular buds. However, it is its striking mix of lavenders, purples, and pinks that make each nug seem like the fruit itself albeit in varying ripeness. To achieve this, aspiring growers must make sure to expose the plant to cooler nighttime temperatures as it nears the end of its maturation cycle. Adding support to its branches will help keep it from breaking off due to the yield’s heavy weight.

Flowering Time

Patience won’t be necessary as Grape Inferno flowers in 8 to 9 weeks. Given that it’s grown by a veteran, the plant produces 16 to 18 ounces per square meter.

In the outdoors, Grape Inferno finishes by the end of September. Under the right conditions, it can produce massive yields there. Experienced growers can an amazing get 21 to 39 ounces per plant.
