What is the Highest Yielding Indoor Strain for Cannabis?

Getting the highest yield possible out of your space constrains is a challenge for every cannabis grower. Micro cultivation license holders need to pay special attention to crop planning because they face the most constraints to allowable growing space.

Growing the highest yielding indoor strains can help maximize the output of your space. Growers who want to get the highest yields possible should also consider utilizing cultivation software to meticulously plan and monitor cannabis crops.

Blue Dream is a cross between the strains Blueberry and Haze. This sativa dominant hybrid originates from California. Blue Dream is a flavorful and aromatic strain that is praised for its high THC levels.

Blue Dream is recommended for medicinal purposes. Its been suggested for health issues like pain, depression, and nausea. Smokers and growers alike are fond of the Blue Dream strain.

Cultivation Tips for Blue Dream

Blue Dream can be cultivated outdoors in its native California climate, but grows best indoors. Blue Dream grows very tall- up to six feet, which can be a challenge to indoor growing.

The tall stalks of Blue Dream need to be staked to support its height and the weight of its flowers. Blue Dream also requires a lot of nutrients and thrives on lots of nitrogen. While most strains need nitrogen levels decreased when they flower, Blue Dream can consume high levels of nitrogen without experiencing nutrient burn.

If you are growing Blue Dream in soil, the pH should be kept between 6.0 and 7.0. For hydroponic cultivation, a pH of 5.5 to 6.5 is ideal. Blue Dream also likes to be kept in a very humid environment during vegetative growth.

Blue Dream is ready to harvest after nine to ten weeks of indoor cultivation. Blue Dream is a very high yielding indoor strain that can yield as much as twenty ounces per plant.

Super Silver Haze is a sativa dominant hybrid that is known for its ability to relieve anxiety and encourage relaxation without being sedative. Super Silver Haze is a cross between Northern Lights, Haze, and Skunk #1. It has been a popular strain since the late 1990's when it won the High Times Cannabis Cup. 

If you are looking for one of the highest yielding indoor strains, Super Silver Haze can deliver up to nineteen ounces of flower per square meter. It takes nine to eleven weeks for this strain to be ready to harvest.

Cultivation Tips for Super Silver Haze

Super Silver Haze can be grown outdoors, but it does best in an indoor hydroponic cultivation system. Warm and humid environments will encourage this strain to reach its full potential.

Stakes and netting are used to support and train high yielding indoor cannabis strains.

Strawberry Kush is an indica dominant hybrid of OG Kush and Strawberry Cough. This strain has sweet berry flavors and provides a euphoric and uplifting high. Strawberry Kush is thought to provide medicinal benefits to those suffering from pain, depression, and appetite problems.

Cultivation Tips for Strawberry Kush

Strawberry Kush can yield up to eighteen ounces per square meter when grown indoors, making it a high yielding indoor strain. Despite its great yields, Strawberry Kush is easy to grow.

This strain grows short and likes warm and humid environments characteristic of the Medeterranian. Strawberry Kush is resistant to many molds and mildews which is a huge benefit to indoor cannabis growers. Strawberry Kush can grow very wide, so pruning is recommended.

Cultivation Tips for White Widow

White Widow is one of the highest yielding indoor strains at eighteen ounces per square meter. Surprisingly, White Widow can thrive outdoors and yield around twenty-one ounces per plant.

Soil or hydroponic grow systems are both appropriate for White Widow. In either system it is highly recommended to use screen of green (SCROG) and keep plants well pruned beneath the netting.

White Widow is ready for harvest after eight to nine weeks and is fairly easy to grow. This strain can be fussy about nutrients. It is recommended to feed plenty of nitrogen during vegetative growth, then flush plants before switching to a high phosphorus nutrient formulation for floral growth.

For any cannabis strain you cultivate indoors, there are some general practices that can help increase yields.

Lighting for Highest Yielding Indoor Strains

Lighting is critical for cannabis plants. Making sure your lighting systems are dialed in and directing light properly is very important. Carbon dioxide (CO2) enrichment can allow plants to use more light and yield large flavorful buds.

Training High Yielding Indoor Strains

Outdoor plants grow best vertically because they are bathed in sunlight from all directions. Indoors, grow lights provide directional light so using techniques like screen of green (SCROG) can help plants take up more light. SCROG plants grow more horizontally so lower branches get as much light as taller branches.

Pay Attention to Details

Master growers tend to have meticulous habits and attention to detail because they know how much impact it can have. Any strain can be a high yielding strain when provided with its optimal grow environment. Details like providing the right strain-specific nutrients and controlling temperature and humidity are critical.
