Requirements for Growth

The Black Diamond Strain has a more euphoric and uplifting high than most other marijuana strains. That’s also the reason why Black Diamond Strain has so many famous relatives.

The Black Diamond Strain can be a tricky plant to grow because it is particularly susceptible to molds, diseases, pests, and environmental stressors like heat and wind. However, the finished flower is nothing short of gourmet.

We recommend growing the Black Diamond Strain indoors, but if you do plan to grow the Black Diamond Strain outdoors, we recommend employing some type of enclosure, like a greenhouse, to help protect your plants from the environment.

For indoor growers who may be unfamiliar with Black Diamond Strain: we recommend lowering your lights to help prevent stretching, which the Black Diamond Strain is known for doing.

It’s important to note that unlike most other cannabis strains, Black Diamond Strain doesn’t tolerate excessive amounts of nutrients very well at all. Most growers who have experience with Black Diamond Strain will tell you to cut your base nutrients in half but add twice as much Cal-Mag as you would normally use.

Black Diamond Strain isn’t a huge yielder so it’s also a good idea to prune your branches early to keep a nice even canopy and prevent your plants from over-shadowing their neighbors and diminishing your overall yield.

The Black Diamond Strain doesn’t always respond well to pruning, so we recommend topping the Black Diamond Strain once to increase overall vigor, and then allowing it to grow naturally after that.

In general, the Black Diamond Strain also does better in larger containers. However, we still recommend starting the Black Diamond Strain in small containers and transplanting them into larger containers after about a month.

This extra step will help strengthen the roots and ultimately increase the overall yield at harvest.

Make sure to use well-draining soil to prevent root-rot and other soil-borne pathogens from diminishing your yield.

The Black Diamond Strain earned its reputation because of its fragrance and flavor. We recommend an all-natural feeding regimen to allow those amazing flavors and aromas to take center stage. Outdoor and greenhouse growers are encouraged to use good, natural compost.

Indoor growers should always maintain a temperature of around 72 – 76 degrees Fahrenheit inside their grow space and keep the air circulating. The Black Diamond Strain doesn’t like high humidity so we recommend taking preventative measures against common molds and fungi, such as powder mold.

You can further increase your yield, and the overall health of your plant, by allowing the substrate to almost dry out in between waterings. This practice will help encourage root growth and lead to a more vigorous outcome.

Always make sure to calibrate your pH meter properly, and always adjust the pH of your water so that the run-off water measures around 6.0.

Also make sure to also allow adequate time for flushing to remove any residual mineral salts that may have accumulated during the bloom cycle to maximize the flavor of the finished flowers.

We recommend that soil growers flush the Black Diamond Strain for 10 to 14 days prior to harvest and that hydroponic growers flush the Black Diamond Strain for 7 to 10 days prior to harvest.

In general, longer flushes tend to produce better flavors and aromas without decreasing yield.

Lastly, be patient. The Black Diamond Strain is a real treat when the buds have the time to fully develop so make sure to monitor the trichomes closely under a 100x microscope and give them time to mature and start to turn amber before harvesting.

If you decide that you would like to try growing the Black Diamond Strain for yourself, just click the buttons below to buy seeds or clones.

How to Start Seeds of

Black Diamond Strain

You can start your seeds in damp paper towels, coffee filters, napkins, or seed starter plugs. Simply dampen the medium with distilled water, place the seeds on the medium, and store in a warm, dark place for 3-5 days.

Once your seeds have sprouted, be sure to transfer them into soil or some other type of substrate as soon as possible.

The Best Soil for Growing

Black Diamond Strain

When it comes to starting young plants, we recommend Tupur Mix by Royal Gold.


Tupur Mix is a coco fiber-based soilless medium that contains a heavy amount of perlite; and nothing else. 

In other words: It's the PERFECT growing medium for seeds, clones, and young plants.

Keep in mind that while mature plants LOVE stuff like seabird guano and earthworm castings, whereas younger plants prefer clean, well-draining soil; and a light nutrient regimen that gets progressively stronger as the plant grows.

That's why we love Tupur Mix - it allows for MAXIMUM control over your feeding regimen!


This substrate is designed to let you feed your plants as often as possible without overwatering or burning your plants.


These unique factors make Tupur Mix ideal for young plants in containers, automated watering systems, drip-to-drain, ebb-and-flow, deep water culture, and aquaponic gardens.


Tupur Mix strikes the perfect balance between drainage and moisture retention while still allowing for adequate aeration to prevent water logging. 

How to Plant Clones of

Black Diamond Strain

When repotting a plant, the substrate should always come out of the smaller container in one piece. 

Another key to transplanting clones is to make sure that the substrate in the new container is saturated with water to allow you to pack the soil down around the plant once it's been transplanted.

Best Nutrients for Growing

Black Diamond Strain

Stop wasting money on overpriced nutrients and start getting the results you want with this COMPLETE nutrient regimen! The Humboldt Secrets Starter Kit will allow you to grow the PERFECT crop every time!

The Humboldt Secrets starter kit has everything you need to get your plants through to harvest and enough concentrate to make between 125 - 150 gallons of solution!

This premium line of nutrients is compatible with all growing mediums and works equally well indoors, outdoors, and in greenhouses!

The Humboldt Secrets line is one of only a few cannabis-specific nutrient products and is made with premium ingredients for maximum nutrient uptake.

That's why we recommend it!

When to Top Your 

Black Diamond Strain

We recommend topping your plants when they're about 24 inches tall and before they begin flowering.

Growers who choose to employ low-stress training techniques (SCROG or SOG) may end up topping multiple times.

Topping a plant temporarily deprives it of growth horomones called auxins that are present in the tips of the shoots and regulate vertical growth. In the absence of these hormones, the plant begins to grow horizontally for a few days until the auxins recover.

This "horizontal growth" leads to the development of multiple meristems that can each eventually support a large flower.

That's why topping is a widely accepted practice that has been shown to dramatically improve yields.

Possible Side Effects of

Black Diamond Strain

Marijuana consumption may trigger adverse effects in some people. Less experienced consumers are more likely to experience side effects, including but not limited to:

  • Dry Mouth

  • Dry or Red Eyes

  • Anxiety

  • Paranoia

  • Dizziness

  • Hunger

  • Increased Heart Rate

In general, these effects dissipate after a few minutes as your body metabolizes the THC.
