Growing Tips for Black Diamond Auto

Growing Black Diamond Auto seeds is relatively straightforward, although it does require extra care and attention through the flowering phase of growth. Even if you have never grown cannabis before, Black Diamond is a solid strain to cut your teeth on. You do not need an experienced green thumb to cultivate this strain. The strain is suitable for both indoor and outdoor growing and prefers a warm, dry climate to really thrive. Whether you grow indoors or outdoors, it is recommended to use organic soil or hydroponics, and you need to provide adequate ventilation and light for optimal growth. When cultivating this strain indoors, you will need to adjust the temperature and light as well as the air circulation to mimic its natural growing environment. Creating a climate similar to that of California summers will ensure that your plants grow to their full potential. When growing this strain outdoors, it requires consistent temperatures and humidity to hit its peak growing capabilities. The best setting for any outdoor grow is a greenhouse, but if you don’t have access to a greenhouse, you can grow this strain in a garden or on a balcony because of its short stature.

Black Diamond Auto plants don’t take up a lot of space, so you can grow multiple plants in a smaller area to increase your yields. It is also crucial to dial in the appropriate soil temperature. The ideal temperature for these plants is around 64-75 degrees Fahrenheit. Humidity levels should be kept around 50-60% during the vegetative stage and maintained at 40-50% during the flowering stage of growth. Keeping the humidity levels below 60% will help keep mold and mildew off your plants.

Utilizing methods like topping and/or Low-stress training can optimize growth and help manage the plant’s size. These methods will increase yields and help to control the canopy, creating even growth where light reaches the bottom-most buds. Black Diamond Auto plants require an 18-20 hour light cycle to get them started and to get them through the vegetative stage. As an autoflowering strain of cannabis, Black Diamond Auto does not require a change in the light cycle to induce the flowering stage of growth.

Black Diamond Auto: Herbal and Grape

    Great for a group outing like camping or skiing! I grow over the summer, harvest in the fall and smoke all winter long. Very bitter and sour and I love it. 5/5!

    I love skiing so thought it might be fun to grow black diamond seeds! I bought 10 seeds online, had em shipped right to my location in Tacoma WA, and I am living the dream! Great buy for a low price. Brilliant flavors and colors….some of the best weed I have ever tasted.

  13. Joshua Flynn (verified owner)

    Sounds a bit challenging, like a difficult ski slope, but in reality is very fresh and tasty. It’s delicious, uplifting, and super nice to have around. I purchased MJ online, had it shipped to my residence and it was there within 7 days of ordering. Just as fast as Amazon, even a little bit faster. What a great place to grow weed. Seattle has the perfect summer climate for MJ, and I have truly enjoyed working with this seed.
    Thank you for the opportunity.

    Even if you’re not hitting the slopes, black diamond really gives you a thrill. Love the sweet and sour nugs, the fruity aroma and a deeply relaxing, and introspective high. Difficult to find elsewhere, Pacific always has these in stock…and the shipping rates are incredible!

  16. Annie F (verified owner)

    This strain has a sweet and herbal taste that I love, and it always leaves me feeling happy, relaxed, and hungry. It was super easy to grow, even as a beginner, and I was impressed with the yield I got from it. Highly recommend for anyone looking for a great tasting and effective strain.

  17. EmeraldEnthusiast (verified owner)

    Breaking new ground with Balck diamond. Excellent color and flavor. Makes my eyes feel kinda out of focus and my brain feel light and buzzy. Kind of like caffeine. Good times all around. Fresh bud, too. Thanks for the awesome seeds!

  18. Kelvin Figueroa (verified owner)

    Black diamond is a deeply energizing and euphoric high, best suited to long-time smokers and experienced growers. It’s a particularly long grow, usually hovering between 12-14 weeks to reach harvest. I tend to enjoy the growing process, especially with seeds of this quality, but if you’re craving some fresh homegrown fast, try another strain ha!
