How to Grow Black Haze Seeds

Once you’ve secured your Black Haze seeds — it’s time to learn how to grow them.

From preferred climate to potential yield, we’ll provide in-depth information and valuable tips to ensure a stellar harvest of Back Haze weed.

Grow Difficulty

The Black Haze strain is rated as moderately challenging to cultivate.

The primary reason why Black Haze presents problems for beginners is due to its long flowering time. At 9-10-weeks (or more), beginners are prone to making small yet devastating mistakes.

On paper, a 10-weeks flowering time seems doable; however, this length of time requires extreme attention to detail, patience, and skill. Therefore, beginners should only embark on Black Haze once they’ve produced 2-3 successful cannabis crops.

Optimal Growing Conditions and Climate

The ideal zone for Black Haze plants is a Mediterranean climate.

In other words, sunny and dry conditions are exactly what Black Haze plants want. Remember, with a 10-week flowering time; your Black Haze crop needs to be harvested well before the onset of frost.

Therefore, most growers tend to cultivate Black Haze seeds indoors for the best results. When grown indoors, Black Haze plants are easier to cultivate due to an optimized environment.

Specifically, Black Haze plants enjoy:

  • High-intensity light (LED or HID)
  • Adequate space
  • 62-84F
  • 40-60% RH

Lastly, Black Haze plants require cold temperatures during the final stage of flowering to produce its signature purple/black weed.

Flowering time

The flowering time of Black Haze is relatively long at 9-10-weeks.

Although Black Haze is slightly sativa-dominant, it flowers like one. Many cultivators don’t have the patience for a 10-week marijuana strain.

However, Black Haze sets off fireworks at the end of flowering, making it worth your time in every regard.

If you grow Black Haze seeds outdoors, you must ensure your environment will not experience frost until the end of October. If your outdoor garden is prone to frost — you must harness a greenhouse to grow Black Haze.


The yield of Black Haze is rated as medium to high.

When grown indoors, the Black Haze strain is capable of producing upwards of 450-grams of deep purple flowers. Alternatively, outdoor-grown Black Haze crops may yield up to 400-grams per plant.


Black Haze produces medium-sized plants.

Therefore, Black Haze can be grown in most indoor and outdoor settings. However, cultivators that are limited on space will find Black Haze plants present a handful of issues.

Remember, the best way to manage the height of your Black Haze crop is via:

  • Topping
  • LST
  • ScrOG

Resistance to Pests and Diseases

The Black Haze strain presents mild resistance to common pests and diseases.

Therefore, you must defend your weed crop at every turn. The best way to do so is by implementing an IPM program, such as:

  • Apply organic pesticides 1-3 times prior to flowering
  • Trim undergrowth to improve air circulation
  • Space plants accordingly
  • Ensure climate (temperature and humidity) are at ideal levels
  • Provide adequate nutrition and water applications
