For most people, the best marijuana seeds for home cultivation are Indica hybrids. Most of these relaxing weeds are hardy in nature, can resist pests and diseases, have quick flowering periods, and provide high yields. Given that these are common traits, it can be challenging when choosing one strain. To simplify the process, we pick the top 5 strongest Indica strains for you.
What Makes One Indica Strain Better than the Others?
Up until a few years ago, the prevailing notion was that choosing the best strain is as simple as looking at the published THC level. Doing so presents two problems.
- Some Indica strains with lower THC are more potent than others that have higher levels.
- THC alone does not account for pretty much everything else, including growth patterns and traits.
At Homegrown Cannabis Co., there are over 400 in-house genetics – the most extensive in the world. At least half are either pure or lean heavily on Indica. There is no doubt that all these are premium quality. However, the sheer number of choices complicates the selection process.
It helps, therefore, if you understand what makes one strain stand out from the rest of the field.
It is impossible to classify Indica strains by THC level. Not only do many share the same concentration, but this cannabinoid is also merely one of over a hundred. Cannabis plants, in fact, constitute some 500 chemical compounds.
THC is the psychoactive component of cannabis. CBD, on the other hand, has touted medicinal benefits and is non-psychoactive. Other beneficial cannabinoids include CBG and CBN.
Terpenes are another class of chemical compounds that are responsible for the smell and taste of cannabis plants. Like cannabinoids, it occurs in different concentrations.
The presence of particular compounds and their concentration makes for the chemotype of a strain. Although some may share striking similarities, expert cultivators and breeders can quickly detect the differences, no matter how subtle. Not only is it evident in fragrance and flavors, but it also heavily influences the effects and potency.
The Entourage Effect
Each of the more naturally occurring chemical compounds exerts particular effects. THC produces the high, while CBD does not, but it does have immense therapeutic values. Myrcene, one of the most common terpenes found in cannabis, imparts a citrusy, musky, herbal scent. It also has anti-inflammatory and anti-bacterial properties and can be sedating.
Researchers also found out that terpenes also interacts with cannabinoids and other compounds. This chemical synergy results in heightening the intensity or potency of the effects of each compound. Called “The Entourage Effect,” this phenomenon explains why some lower THC strains are more intense than those with higher THC.
The 5 Most Powerful Indica Strains
Unfortunately, there is no easy way to pre-determine the potency and effects of a strain. Granted that Indica hybrids have common traits such as easing muscle tensions and promoting relaxation, it is the subtle nuances that set one apart from the others.
For starters, choose from among these strains, and you can never go wrong.
1. Kosher Kush
- THC: 22-29%
- Flowering Time: 9-10 weeks; Mid October
- Yield: 450-550 gr/sqm; 400-500 gr/plant
Meeting someone to say there is another Indica strain more potent than Kosher Kush is highly improbable. A perfect grown plant can develop flowers boasting of 29% THC – that is insane. Originally clone-only, Homegrown Cannabis Co. can deliver its feminized seeds worldwide.
After delivering a gentle euphoric buzz during the onset, the heavy-hitting physical effects slam into the body, quickly melting stress, easing muscle tensions, and enhancing the mood. The relaxing property continues to intensify, leading to a full-on couch-lock and eventually – sleep. These remarkable effects earned it the title of Best Indica in 2010 and 2011 stagings of the Cannabis Cup. It was also the High Times Strain of the Year for 2011.
For an Indica strain, Kosher Kush can grow quite tall indoors, and thus requires topping to manage its height. It adapts well to training – Sea of Green (SOG) or Screen of Green (ScrOG). Once the flowers start developing, it also emits an herbal, citrusy, lemony fragrance, courtesy of dominant terpenes – myrcene and limonene. After 9 to 10 weeks, the yield per square meter should reach 550 grams.
2. Purple Kush
- THC: 15-27%
- Flowering Time: 6-8 weeks; Late September
- Yield: 400-500 gr/sqm; 600 gr/plant
Purple Kush combines the desirable genetics of two Indica landraces – Purple Afghani and the Hindu Kush. For most people, including beginners, this strain can average 22% THC. Experts, on the other hand, can push it to reach 27% THC.
The full effects of this strain do not come surging into the body moments after smoking or vaping. It, instead, starts with a gentle cerebral stimulation that ushers in the sense of happiness. After 20-40 minutes, it delivers a crushing blow, sending you deep into introspection, oblivious to stress and pains. Because of sedating, numbing effects, the best time to use this strain is at the end of the day when there are no more tasks to do.
Purple Kush is a small-to-medium-sized strain that features numerous lateral branches and thick foliage. Trimming and pruning, as well as training with LST, can help boost its yield significantly. At only 6 to 8 weeks, it is one of the quickest flowering feminized strains ever developed. To help bring out the purple coloration, keep the nighttime temperature around 10 degrees lower than during the day.
Incidentally, Purple Kush is also available as auto-flowering seeds. THC production is a little bit lower, ranging between 15% to 20%. It more than makes up by reaching maturity in only 10 weeks after germinating the seeds. This auto is perfect for people who are overzealous in getting their hands on the buds, or those who cannot tolerate insanely high THC.
3. Grape Ape
- THC: 22-26%
- Flowering Time: 7-8 weeks; Early October
- Yield: 350-500 gr/sqm; 600 gr/plant
Grape Ape is not at all behind Blueberry as among the best smelling Indica weed strains. It is also among the most potent with up to 26% THC. Primarily, its terpenes constitute myrcene, pinene, and caryophyllene. These compounds synergize the cannabinoids, unleashing an intensely relaxing experience.
The premium quality of this strain can be traced to its legendary genetic forerunners – Mendocino Purps, Skunk #1, and Afghani. A stimulating cerebral buzz characterizes the quick onset of the high while the physical effects come later. Once it kicks in, Grape Ape can quickly melt away stress and anxiety, relieve pain, and enhance the mood. Any motivation to be productive ceases while the body succumbs to couch-lock.
Among the most potent Indica strains, Grape Ape is one of the smallest, averaging 3 feet tall indoors. Like Purple Kush, it is a beautiful plant, boasting of purple hues in the foliage and buds. Although compact in size, its yield per square meter is surprisingly generous at 350 to 500 grams.
4. Critical Kush
- THC: 22-26%
- Flowering Time: 7-8 weeks; Late September to early October
- Yield: 600 gr/sqm; 650 gr/plant
Critical Kush combines the ability of Critical Mass to produce massive-sized flowers and the full-bodied relaxing properties of OG Kush. The union and all the painstaking work also focused on increasing the average THC levels of the genetic cornerstones.
This creeper, at the risk of being repetitive, is profoundly relaxing. After a gentle head-clearing high, it sweeps across the body, eliminating muscle tensions and pains. In small doses, some people may find the relaxed demeanor accompanied by increased libido. An average dosage, on the other hand, mostly leads to laziness and preference to stay on the couch and sleeping.
Growing this crippling strain is made more convenient by Homegrown Cannabis Co. Feminized Critical Kush seeds, for example, has an exceedingly high germination rate. Once the sprouts emerge, the stability of the genetics becomes evident as the plants vigorously grow into heavy-yielding plants. The massive colas and branches will need some form of support as its production could reach 600 grams per square meter.
5. Master Kush
- THC: 18-25%
- Flowering Time: 7-9 weeks; Late September to early October
- Yield: 400-500 gr/sqm; 500 gr/plant
Master Kush is one of the purest Indica strains you can obtain. At up to 25% THC, it rounds up the world’s 5 most potent Indica strains. As a testament to its greatness, it had won the Cannabis Cup – two times – in 1992 and 1993.
Also of Hindu Kush descent, the addition of Skunk #1 genetics provided for a superb euphoric buzz balanced by a magnificent body stone. A small-to-moderate dosage is unlikely to induce a mind-bending high. Instead, the psychoactive effects still give you room to engage in some physical activities. Up the dosage, though, and it can be just as devastating as any of the top Indica strains.
Beginners can cultivate Master Kush and harvest a decent yield. Combining the growth with LST, such as SOG, can boost the production as well as improve the overall quality. Size does not matter as the compact, but bushy strain stands around 3 feet tall indoors.
