The Flavor of Blood Diamond OG

This OG Kush descendant has that classic OG flavor but with a deeper, richer twist. When you smoke it, you get this earthy pine and fuel combo right up front, followed by a subtle citrus tang and a hint of spice on the exhale. It’s bold, gassy, and smooth - the kind of flavor that sticks to your tongue in a good way.

That signature taste comes from a heavy dose of myrcene, which gives it that musky, herbal base, along with caryophyllene for the peppery bite and limonene adding a touch of citrus brightness. It’s the perfect strain for anyone who loves that strong OG Kush profile but wants something even more flavorful and full-bodied. If you're chasing gassy, terp-rich strains, Blood Diamond OG delivers every time.

How to Grow Blood Diamond OG Marijuana Indoors and Outdoors

What to Watch for When Growing Blood Diamond OG - One of the nice surprises with this strain is that it’s fairly resistant to mold and common pests, especially for an OG Kush variety. That said, the buds get super dense and sticky in late flower, so it’s still important to maintain airflow and keep humidity in check in bloom to avoid bud rot. Pro tip: Even though it holds up well, it’s smart to stay protected - use Holi Moli Eliminator to help guard against mold, mildew, and pests before they become a problem.

Temperature Swings: This strain prefers stable temperatures. It can handle minor shifts, but big swings between day and night can stress the plant, slow growth, or cause light foxtailing during flower.

Nutrient Sensitivity: It isn’t overly sensitive, but it’s important not to overdo it - especially with nitrogen during flowering, which can cause leaf clawing, mess with pH, or mute the strain’s flavor. To keep things simple and consistent, use Holi Moli Juice - it’s an all-in-one nutrient bottle that takes you from veg through harvest without needing a complicated feeding schedule. Just follow the label, monitor your runoff pH, and your plants will stay happy and dialed in.

Odor Control: Yes - you absolutely need odor control. This beauty starts getting loud halfway through veg, and by mid-flower, your space will smell like earthy gas, pine, and citrus funk. If you’re growing indoors or trying to stay discreet, a quality carbon filter is a must.

Flowering Stretch: It has a moderate stretch when flipped to 12/12 - expect about 1.5x its height. It won’t take over your grow space, but it does need a bit of headroom. Pro tip: Flip when your plants are about 20–24 inches tall indoors (usually around 5 to 6 weeks) to stay ahead of it and maintain good light coverage.

Branch Support: It might stay on the shorter side, but it packs on thick, weighty colas - especially in the final few weeks of flower. If you don’t set up support early, those side branches can start to lean or even snap under the weight. Pro tip: Add bamboo stakes, plant yo-yos, or a light trellis net around week 3 of flower to keep everything upright. It’s a simple step that can save your harvest and help those buds develop fully without stress or damage.

Best Climate to Grow Blood Diamond OG Cannabis

This trichome-loaded cultivar thrives in warm, dry climates where it can soak up full sun without battling high humidity. This strain loves long, sunny days and stable weather - set your plants in a bright, open spot where they can absorb 6–8+ hours of direct sunlight and enjoy a natural breeze flowing through the branches.

To manage humidity in this climate, water early in the morning so excess moisture can evaporate before nightfall. Lay down a layer of mulch around the base of each grow bag — this helps keep the soil cool and moist without raising the humidity around the buds. Prune the lower branches early to improve airflow through the canopy and keep mold risk low during flower.

Use fabric grow bags for better drainage and root aeration, and set them on well-draining ground, never directly on concrete or hot surfaces. Here’s how much space to leave between plants depending on the bag size:

Grow Bag Sizes & Spacing:

• 5-gallon bags – 2–3 feet apart
• 10-gallon bags – 3–4 feet apart
• 15-gallon bags – 4–5 feet apart
• 20-gallon bags – 5–6 feet apart (Perfect if you want to let your plants reach full outdoor size and yield potential)

How to Grow Blood Diamond OG Marijuana in Subtropical Climates

This frost-covered OG can be grown in hot, arid subtropical climates, but you’ll need to take some extra steps to manage heat and humidity, especially during late flower when buds get chunky and sticky.

Use fabric grow bags to keep the roots cool and well-aerated, and place them on well-draining soil, not concrete or stone surfaces. Lay down mulch around the base of each plant to help regulate soil temperature and retain moisture without raising humidity levels.

Water early in the day to avoid evaporation loss, and if temps climb above 90°F regularly, set up a white shade cloth (never black - it traps heat) to keep your plants from getting scorched. Choose a location that gets plenty of sun and a steady natural breeze, or use a small fan to help move air through the canopy.

Because subtropical climates are more humid, mold can creep in fast - especially in thick, trichome-heavy buds like Blood Diamond OG. To stay ahead of issues, spray Holi Moli Eliminator preventatively during early to mid-flower. It’s a great way to protect against mold, mildew, and pests before they take hold.

Also, prune the lower branches early to improve airflow under the canopy and help dry things out quickly after watering or rainfall.

Grow Bag Sizes & Spacing:

• 5-gallon bags – 2–3 feet apart
• 10-gallon bags – 3–4 feet apart
• 15-gallon bags – 4–5 feet apart
• 20-gallon bags – 5–6 feet apart

How to Grow Blood Diamond OG Marijuana in Temperate Climates

This powerful phenotype can be grown in temperate climates, but you’ll need to take a few extra steps to handle the cooler nights, increased humidity, and potential rainfall - especially during flowering.

Start by germinating your seeds indoors in early spring, then transplant them outside once nighttime temps stay consistently above 50°F. Use fabric grow bags to improve drainage and root airflow, and place them on well-draining soil or gravel - not directly on cold, wet ground.

Choose a sunny, open location that gets strong natural airflow. Avoid low-lying areas where moisture can collect. To help regulate soil temperature and avoid mold, use mulch at the base of each plant and prune lower branches early to open up the canopy.

During flower, try to keep humidity below 50%, especially in the last few weeks. If heavy rain is expected, use a temporary greenhouse cover or tarp to protect your buds. Also consider spraying Holi Moli Eliminator preventatively to guard against mold and mildew during wetter periods.

Grow Bag Sizes & Spacing:

• 5-gallon bags – 2–3 feet apart
• 10-gallon bags – 3–4 feet apart
• 15-gallon bags – 4–5 feet apart
• 20-gallon bags – 5–6 feet apart

How to Grow Blood Diamond OG Cannabis Indoors

This resin-rich strain does best with stable temperatures, especially during flowering. During the lights-on period, aim for 72–80°F, and during lights-off, keep it around 65–70°F. While it can handle small fluctuations, big temperature swings - especially at night - can stress the plant, slow growth, or affect bud development. Consistency is key for getting tight, trichome-rich colas.

In vegetative stage, maintain humidity levels between 55–65% to promote healthy leaf and root growth. Once you flip to flower, gradually drop the humidity to 40–45% by mid-bloom. Because this beauty develops chunky, sticky buds, excess moisture can lead to mold if you’re not careful. In the final 1-2 weeks before harvest, lower the humidity even further to 35–40% to help tighten up the buds and prevent mold.

For indoor grows, use fabric pots for better drainage and root aeration. Go with 5–7 gallon pots for most tents and grow rooms, or upgrade to 10-gallon pots if you’ve got the space and want to push for bigger yields. Space your plants about 18–24 inches apart to allow for proper airflow, light penetration, and ease of maintenance around the canopy.

If you have some experience or want to improve your grow game, this strain responds very well to training. Topping, LST (low-stress training), and SCROG (screen of green) can all help control height and create a more even canopy. Training early in veg encourages more bud sites, better airflow, and ultimately larger yields - especially with this strain’s dense flower structure.

You’ll definitely want a carbon filter. This strain starts throwing off a loud, gassy aroma even before flower, and by mid to late bloom, your space will be filled with diesel, pine, and citrus funk. Install oscillating fans above and below the canopy to keep air moving and prevent hot spots or moisture buildup. If your room tends to run humid or is sealed, a dehumidifier is strongly recommended - especially during the final weeks of flower when bud rot becomes a risk.

Lighting makes a huge difference. This plant thrives under strong, full-spectrum LED grow lights. Most growers use 6500K during veg and switch to 3000K or 3500K for flower, but here at Holi Moli, we run 6500K from start to finish and consistently see tight, frosty buds with intense flavor and resin production. Better lights = bigger yields, higher potency, and top-shelf flower. If you want results that stand out, investing in good lighting is 100% worth it.
