The Flavor of Blood Diamond OG

This OG Kush descendant has that classic OG flavor but with a deeper, richer twist.

It’s bold, gassy, and smooth - the kind of flavor that sticks to your tongue in a good way.

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.

Germination: Ease into your grow with Holi Moli’s germination and transplanting guide— designed to spark steady, healthy root growth and set the stage for strong, thriving plants from the very beginning.

Nutrient Sensitivity: This trichome-packed strain responds well to balanced feeding, but be cautious not to overload nitrogen in flower. Too much can throw off pH and mute the earthy, pine-and-gas terpene profile. Holi Moli Juice offers a simple, full-spectrum nutrient solution to carry plants from veg to harvest while keeping growth healthy and flavors bold.

Odor Control: Expect a strong, earthy-pine and gassy aroma that intensifies in bloom. Indoors, a reliable carbon filter is a must to keep the smell contained. Outdoors, avoid planting near property lines if discretion is important.

Stretching: This powerful indica shows moderate stretch during the first 2–3 weeks of flower. Pro Tip: Flip to 12/12 when plants are 20–24 inches tall (around week 5–6) to control stretch, balance the canopy, and prevent overcrowding.

Branch Support: The heavy, resin-rich buds can weigh down branches as they mature. Use stakes, trellis netting, or yoyos to support colas and prevent bending or breakage in late flower.

Best Climate to Grow Blood Diamond OG Cannabis

This resin-drenched, high-THC strain thrives in warm, sunny outdoor conditions where it can soak up 8–10 hours of direct sunlight daily and enjoy a steady, natural breeze. Choose a wide-open spot with strong airflow to keep the canopy dry and the dense, trichome-coated buds in prime condition.

Avoid planting near fences or walls, as these trap humidity, block airflow, and cast unwanted shade—slowing growth and creating conditions where mold can develop.

Opt for fabric grow bags instead of plastic pots—fabric allows better root aeration, improves drainage, and helps stabilize soil temperatures. Plastic retains heat and moisture, which can stress plants in direct sun.

Grow Bag Sizes & Spacing:

• 10-gallon bags – 3.5–4 feet apart
• 15-gallon bags – 4.5–5 feet apart
• 20-gallon bags – 5–6 feet apart (Ideal for growers who want to see their plants flourish naturally and reach peak performance in an outdoor environment.)

Do not place bags directly on concrete or reflective surfaces. These surfaces can radiate heat into the root zone, reduce drainage, and stunt plant development.

Even in a dry, sunny climate, humidity can spike early in the morning or after rainfall. Water in the early morning so leaves dry before nightfall, mulch around the base to insulate roots and maintain steady soil moisture.

While this potent indica strain has some natural resistance, its compact bud structure can still invite pests or mold in certain conditions. Apply Holi Moli Eliminator from veg through flower to guard against mold, mildew, bud rot, and pests—keeping your harvest healthy and top-shelf.

How to Grow Blood Diamond OG Marijuana in Subtropical Climates

This frosty, trichome-packed beauty can thrive in hot, arid subtropical conditions when given the right care to handle extreme sun and rapid moisture loss.

Select a wide-open grow site that receives 8–10 hours of direct sunlight daily and steady airflow to keep the canopy comfortable. Avoid planting near fences or walls, as these can trap heat, block airflow, and cast unwanted shade—slowing growth and creating damp spots where mold may still appear even in drier climates.

Use fabric pots instead of plastic—fabric allows roots to breathe, promotes healthy aeration, and prevents heat buildup in the soil. Plastic containers retain heat and moisture, stressing plants under intense sunlight.

Grow Bag Sizes & Spacing:

• 10-gallon bags – allow 3.5–4 feet of space
• 15-gallon bags – allow 4.5–5 feet of space
• 20-gallon bags – allow 5–6 feet of space

Do not place bags directly on concrete or reflective surfaces. These surfaces radiate heat into the root zone, restrict drainage, and can stunt growth.

While dry air helps reduce mold pressure, the intense sun can dehydrate plants quickly. Water deeply in the early morning so roots absorb moisture before peak heat, and add a thick mulch layer to insulate the root zone and slow evaporation. If daytime highs regularly exceed 90°F, consider using white shade cloth during the hottest hours to reduce stress without blocking sunlight. Avoid black shade cloth, as it absorbs and radiates heat, making conditions harsher.

Even in arid climates, pests like spider mites and aphids can target the chunky, resin-rich buds of this powerhouse strain. Inspect plants regularly, maintain airflow, and spray Holi Moli Eliminator from veg through flower to help defend against mold, mildew, bud rot, and pests, keeping your harvest strong, healthy, and top-shelf.

How to Grow Blood Diamond OG Marijuana in Temperate Climates

This high-potency indica can perform very well in temperate climates, but growers need to manage seasonal humidity, fluctuating temperatures, and late-season rainfall carefully. For the best results, start seeds indoors in early spring and transplant outdoors once nighttime temps consistently stay above 50°F. This gives your heavy-yielding plant a strong head start before it faces the unpredictable conditions of a temperate season.

Choose an open grow spot that gets 8–10 hours of direct sunlight daily and steady natural airflow. Good circulation helps prevent mold from forming in the thick, sticky buds. Avoid planting near fences or walls, as these can trap humidity, block airflow, and cast unwanted shade—slowing growth and increasing the risk of disease.

Go with fabric grow bags instead of plastic—fabric provides superior drainage, better root aeration, and helps stabilize soil temperatures, while plastic can hold heat and moisture, stressing plants during seasonal changes.

Grow Bag Sizes & Spacing:

• 10-gallon bags – 3.5–4 feet
• 15-gallon bags – 4.5–5 feet
• 20-gallon bags – 5–6 feet

Never place grow bags directly on concrete or reflective surfaces. These radiate heat into the root zone, restrict drainage, and can stunt growth.

This resin-loaded lady is vulnerable to mold in humid or rainy periods. Prune lower branches, thin the canopy for airflow, water early in the morning so leaves dry before nightfall, and mulch the base to maintain even soil moisture. If rain is expected late in flower, use a rain cover or simple greenhouse to protect the heavy colas from prolonged wetness.

Even with moderate resistance, this powerful strain benefits from preventative care. Apply Holi Moli Eliminator from veg through flower to help defend against mold, mildew, bud rot, and pests—keeping your harvest potent, healthy, and top-shelf in quality.

How to Grow Blood Diamond OG Indoors | Complete Guide

This resin-loaded indica thrives in a warm, steady climate. Keep temps between 75–80°F during lights-on and 65–70°F during lights-off. Avoid major fluctuations, as large temperature swings can stress plants, slow bud development, and impact yield.

During veg, keep relative humidity around 60–65% to encourage lush foliage and strong root development. Once flowering begins, gradually reduce humidity to 45–50% to protect the thick, resin-coated buds from mold and mildew. In the last two weeks before harvest, drop RH further to 40–45%, or even 35–40% if your environment allows, to tighten colas, preserve terpene richness, and ensure a clean, mold-free finish.

Use fabric grow bags instead of plastic pots— fabric promotes stronger root aeration, better drainage, and more stable soil temperatures. For most indoor setups, 5–7 gallon fabric pots are perfect. Always allow 2.5–3 feet between each plant to ensure proper airflow and prevent overcrowding.

This high-THC powerhouse responds well to training. If you’re experienced or want to push your skills, topping, low-stress training (LST), or setting up a SCROG can improve light penetration and maximize yields. Newer growers can stick with simple LST and light defoliation until they’re confident with more advanced techniques.

Expect a strong earthy-pine and gassy aroma in late flower, which can easily fill your grow space. A carbon filter is essential indoors to manage odor. Pair it with oscillating fans to circulate air through the canopy and a dehumidifier to keep moisture levels steady, especially in the final weeks when buds are most vulnerable.

Lighting is one of the biggest factors in how this trichome-coated indica performs. Full-spectrum LEDs are ideal. Many growers use 6500K during veg and switch to 3000K–3500K in flower, but our growers here at Holi Moli have seen excellent results keeping plants under 6500K from start to finish—producing dense, frosty buds with bold aroma and top-shelf bag appeal.

Lighting is where good grows become great. Using underpowered or poor-quality fixtures will only produce loose buds, thin resin layers, and lackluster flavor. If you want dense, potent flower with true bag appeal, commit to high-quality, efficient lights—because in the end, your yields and bud quality depend on it.
