Every grower wants a good harvest. Whether you are growing outdoors or indoors. The biggest advantage of growing indoors is complete control over the growing environment. You can control lighting, temperature, water, humidity, and carbon dioxide levels with relative ease. It is also much easier to prevent the growing environment from pests and diseases.
Home-growing marijuana is becoming more common, whether it's a hobby or a self-sufficiency method. Increasing production and improving quality is the pursuit of every grower.
The first step in increasing yields begins with selecting high-quality, high-yielding strains.
Growing the highest-yielding indoor strains can help maximize the yield of your space. A plant's genetics play a huge role in how the plant grows, how the shoots become hypertrophic, and ultimately, yield.
The strains available today achieve higher yields and are more potent than anything from a decade ago. Strain potency, yield, and growing convenience have been steadily improving over the past few decades as hundreds of growers around the world continue to develop new strains and improve older varieties.
4 Best Indoor Strains for Yield and Potency:
Strawberry Kush is a hybrid marijuana strain made by crossing Strawberry Cough with OG Kush. This strain produces sedating effects that can be felt in the body and mind. Strawberry Kush features a musky strawberry taste that lives up to its name. This strain is potent, so it's best reserved for consumers with a high THC tolerance. Growers say Strawberry Kush has a flowering time of 8-9 weeks.
Chocolope, sometimes referred to as D-Line, is an almost entirely sativa hybrid with a very complex taste profile. Chocolope's hefty buds give earthy, sweet coffee flavors that provide a dreamy, cerebral effect. Consumers report a strong, euphoric mental shift that is great when coping with depression or stress.
Super Silver Haze
Super Silver Haze is a repeat High Time Cannabis Cup winner. The strain grows tall with long branches, vivid green leaves, and both white and orange stigma hairs in a 70-77 day flowering period. Super Silver Haze is often chosen to treat conditions such as chronic fatigue, depression, chronic stress, migraines or headaches and nausea or appetite loss. This bud has a classic spicy herbal flavor with a sharp sour citrus exhale. Super Silver Haze is best grown outdoors in a hot, sunny, warm, tropical climate, which not everyone in the world can access. However, if you are fortunate enough to live in these conditions, growing Super Silver Haze outdoors may be a more cost-effective option than growing it indoors.
Legendary for its off-the-charts resin production, White Widow is a staple sativa-dominant hybrid with powerful energizing effects. This strain has an average THC composition of 20%, with some phenotypes exceeding that amount. Buds of White Widow are chunky and somewhat conical and tapered. Despite a mostly sativa high, White Widow look much more indica during the vegetative stage: plants are bushy and wide, and rarely exceed 6 feet in height. The plants flower within 9 weeks when grown indoors and are ready for harvest in early October when grown outdoors.
Increase light intensity
Cannabis is a light-loving, short-day crop, and cannabis needs light to grow. The conversion of light into energy by cannabis through photosynthesis is how plants get all their energy to grow and produce buds. If your cannabis plants are free of major problems or diseases, the biggest factor affecting your yield is the amount of light provided.
You need to use direct and evenly distributed light throughout the growing canopy to maximize the available light. In the veg stage, they need at least 18 hours of light a day. Some growers give them 24 hours of light a day, switching the lighting schedule to 12 hours on and 12 hours off during flowering. You should always keep in mind the distance required for your lighting setup. Increasing the light intensity will further promote the photosynthetic process and lead to more shoot development and growth.
Adding carbon dioxide is necessary. Because under high-intensity light, more carbon dioxide can be consumed to produce more sugar that plants need. Adding extra carbon dioxide at the right time can help boost cannabis production. It's important to note, however, that adding more carbon dioxide won't increase yields if plants aren't maximizing light use.
Feed your plants correctly
Choose the right ratio of nutrients to feed your cannabis plants at the right time. Cannabis has its own requirements for the ratio of each nutrient required for each developmental stage, which means that the ratio of nutrients required by cannabis is not the same during the growth and flowering stages.
During the growing stage, NPK mixtures that are high in nitrogen (N), moderate in phosphorus (P), and high in potassium (K) work best.
During flowering, NPK mixes that are low in nitrogen (N), medium to high in phosphorus (P), and high in potassium (K) work best.
When you choose nutrition and supplements, try to choose from the same company, because the nutritional ratios of different merchants may vary.
Most companies will provide a schedule, and you just need to use this schedule to feed your cannabis with the correct nutrients.
When should you start providing nutrition to your plants? Once the plant has grown its first set of serrated leaves, starts providing the plant with nutrients. The flowering process has already begun when you see the first signs of the flowering stage and the plant begins to develop pistils. If you plan to switch to flowering soon, you can start using flowering nutrition from week 4 or 5 of the vegetative phase. If you plan to give your plants a longer vegetable period, you can switch to flowering nutrition when the plants are large enough for the growing environment.
Train your weed plants
Plant training is aimed at larger, wider plants and many evenly distributed colas that can produce bigger yields. Training your plants is a basically free way to increase your yields without changing anything else in your setup.
Low-Stress Training (LST)
This is a training method where instead of atop the main branch, it is tied and trained to grow horizontally so that the other branches grow faster. There are different ways to tie the side branches, and in some cases using twine, wire or even heavy objects has proven to be most effective. You should carefully bend the main cola so that other budding areas have a better chance of receiving more light.
High-Stress Training (HST)
This method differs from previous ones in that they damage plants in very specific ways. These training techniques involve more risks, but if done correctly, they can greatly improve the final yield. This is the process of deliberately destroying the cell walls inside the cannabis plant using pressure from the fingers and thumb. This technique is classified as high pressure and should only be performed by more experienced growers, as you have to be very careful to apply only enough pressure to damage the cells inside, rather than completely breaking the branch or stem.
Screen of Green
The Screen of Green method, better known as ScrOG, is a technique for optimizing cannabis yield per square foot. The theory behind the ScrOG method is to manipulate the shoots of plants to grow horizontally rather than vertically, thereby exposing more of the flower nodes to the light source. Growers can use metal or plastic screens or meshes through which plants grow and spread outward. Once the plants are trained to grow horizontally, they will ideally form a thick upper canopy that prevents light from penetrating the leaves below, ensuring that light reaches all the places where it is most needed.
Topping & FIMing
Topping is a pruning technique in which primary branches are cut off to encourage secondary branches to grow with greater vigor. A plant can be topped multiple times, and with each topping, the number of dominant shoots doubles. This happens because the growth hormone is removed from the new growth. More of these hormones will be sent to the cut and induce the plant to grow two or more branches at the site. The best time to top a plant is early in its growth. The 4th or 5th node is usually the most frequently pruned node.
FIMing is a more sophisticated version of topping. You need to remove a specific part of the top of the cannabis plant. When you delete only the topmost region, you can generate four branches instead of the two associated with the top.
Larger leaves on weeds are usually removed during the flowering stage, in order to redistribute energy to the bud sites. Removing over-covered foliage on lush plants also allows better light penetration to the underside of the plant. It also greatly increases airflow and air exchange through the canopy, which helps combat pest, mold, and fungal problems.
Finally, harvest at the right time
For most cannabis varieties, there is a 2-3 week window to harvest buds. Make sure you have a good idea of when your plants will bloom. If you harvest your shoots too early, you can lose up to 25% of growth. Most shoot growth occurs in the last two to three weeks of harvest time. If you harvest too late, you may lose some of the bud's potency as the trichome content begins to deteriorate.
