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. Learning about how to grow cannabis from seed's will take you a long way as it will help you derive the most value from your growing space. Also something to look into: tissue culture propagation is a budding alternative growing method which can be more scalable. Worth looking into!

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

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.

Average Yield for Blue Dream Plants

When a Blue Dream plant is grown under optimal conditions, cultivators can expect an average of 21 ounces per square meter in an outdoor environment, and 19 ounces per square meter in an indoor environment.

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. Besides height, it is also worth tracking transpiration amounts and levels. This doesn't only pertain to Blue Dream, but all strains. Just a quick tip!

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 (we hope, of course, that this is living 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. Another quick tip and monitoring point: we highly recommend that you optimize your cannabis cultivation lighting to reap the maximum returns from your grow.

Super Silver Haze

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.

Average Yield for Super Silver Haze Plants

Super Silver Haze Plants are renowned for their high-yields. In fact, when a Super Silver Haze Plant is grown under optimal conditions, the plant can yield 28.2 ounces per square meter in an indoor environment.

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.

Strawberry Kush

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.

Average Yield for Strawberry Kush Plants

Strawberry Kush plants also have relatively high yields. When grown under optimal conditions, these plants can produce 19.5 ounces per square meter, in an indoor environment.

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. It's important to make sure that you understand how deep to plant cannabis seed, which can differ depending on the strain.

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. You may also want to try techniques like screen of green (SCROG) with this strain.

White Widow

White Widow was first bred by Green House Seeds in the 1990's. White Widow comes from the Netherlands but is a cross between a Brazilian landrace sativa and a South Indian landrace indica.

White Widow is one of the older high potency strains. It offers a relaxing and balanced high that can help with stress, depression, fatigue, and pain.

Average Yield for White WIdow Plants

According to Royal Queen Seeds, White Widow plants can yield an average of 16 to 19 ounces per square meter, in an indoor environment. Contrasting that with the outdoor

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 weed 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.

How to Increase Yield Per Plant

As cannabis cultivators, we're always striving to increase our plant yields. Thinking through different cultivation strategies, tips, and even hacks to increase the yield output. Let's make this easier for you, and share the science-backed factors that have been proven to increase cannabis plant yield.

Before we get to that, it's important to understand that average plant yields can vary significantly between cultivators, grow environments, and even strains. On average, a single plant can produce up to 907.2 grams (32 Oz) of Wet Cannabis, which translates to approximately 181.4 grams (6.4 Oz) of dried cannabis. Now, how do we set you up for success, to have an above-average yield.


Cannabis plants require three main nutrients at all stages of their plant growth, these macronutrients are nitrogen (N), phosphorus (P), and potassium (K), otherwise known as NPK. Take a look at our post on choosing the best fertilizer and nutrients for marijuana to learn more. 


Cultivators need to strike a balance in their lighting setup, setting up the lighting potency to be powerful enough to encourage growth and bigger buds, while not over-doing it and causing plants to burn. Take a look at our post on cannabis cultivation lighting to learn more about best practices.

Temperature & Humidity

Each strain is unique, and cultivators should set up the grow environment accordingly. Some strains require a delicate, warm, and dry environment. While others may require warmth, and the right amount of humidity. Take a look at our guides on setting the ideal humidity level for cannabis at each stage of growth, and setting up environmental controls for grow rooms.

Cannabis Consulting

For any cannabis strain you cultivate indoors, there are some general practices that can help increase yields. As you dive into the weeds of it (PUN intended!), cannabis strain selection can get quite tricky. Here are some quick tips:

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
