How to Grow Black Princess Marijuana Indoors and Outdoors

What to Watch for When Growing Black Princess - It has decent natural resistance, but once those buds start stacking and getting sticky in late flower, you’ll want to keep humidity in check and airflow strong. Regular pruning and spacing go a long way. To stay ahead of issues, spray with Holi Moli Eliminator during flower to prevent mold, mildew, bud rot, and common pests like aphids or spider mites.

Germination: Start your grow using Holi Moli’s germination and transplanting guide— designed to spark rapid, healthy root growth and set the stage for robust, top-performing plants.

Nutrient Sensitivity: This high-energy cultivar responds well to a balanced feeding schedule. Avoid pushing nitrogen too hard in flower, as it can throw off pH and mute the strain’s bright, fruity terpene profile. Holi Moli Juice offers a full-spectrum nutrient program that can carry your plants from veg through flower while keeping feeding simple and effective.

Odor Control: Expect a bold, tropical-fruit-and-spice aroma during bloom that can carry far. Indoors, a quality carbon filter is essential. Outdoors, plant away from property lines if you need to keep scents discreet.

Stretching: As with many sativa strains, you can expect significant stretch—sometimes doubling in height—during the first 2–3 weeks of flower. Pro Tip: Flip to 12/12 when plants reach about 20–24 inches tall (week 5–6) to keep height manageable and the canopy even.

Branch Support: This tall, vigorous sativa produces long colas that can get heavy as they stack up. Use stakes, trellis netting, or plant yoyos to support branches and prevent bending or breakage in late flower.

Best Climate to Grow Black Princess Cannabis

This tall, tropical-fruit-scented sativa-dominant 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 an open, sun-drenched location with plenty of airflow to help keep the canopy dry and the long, resin-coated colas healthy. Avoid planting near fences or walls, as they can trap humidity, block airflow, and cast unwanted shade—slowing growth and encouraging mold.

Opt for fabric grow bags instead of plastic pots—fabric provides superior root aeration, better drainage, and more stable soil temperatures. Plastic can trap heat and moisture, which can stress plants and hinder growth in direct sun.

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 (Allows roots the space they need to grow and fully develop—healthy, established root systems drive larger, more vigorous plants with the potential for increased size and heavier harvests.)

Avoid placing grow bags directly on concrete or heat-reflective surfaces, as these can overheat the root zone, cause poor drainage, and restrict development.

Even in dry weather, morning dew or late-season showers can raise humidity around the plant. Water early so leaves dry before nightfall, apply a thick mulch layer to insulate the root zone and maintain even soil moisture, and follow the spacing guidelines above for proper airflow.

While this vigorous sativa has decent resilience, its elongated bud structure can still attract pests or develop mold in humid pockets. Use Holi Moli Eliminator from veg through flower to protect against mold, mildew, bud rot, and pests. Safe for the entire plant life cycle, it’s essential for maintaining top-shelf quality and bold aroma.

How to Grow Black Princess Marijuana in Subtropical Climates

This resin-rich princess can thrive in hot, arid subtropical climates when given the right care to manage extreme heat and conserve moisture. Choose a bright, open location with 8–10 hours of direct sunlight daily and a steady natural breeze.

Avoid planting near fences or walls, as they trap heat and humidity, restrict airflow, and cast unwanted shade—slowing growth and creating conditions for mold even in a dry climate.

Always go with fabric grow bags over plastic pots—fabric promotes superior root aeration, improves drainage, and helps regulate soil temperature during peak heat. Plastic can trap heat and moisture, which can stress plants and hinder growth in intense sun.

Grow Bag Sizes & Spacing:

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

Avoid setting grow bags directly on concrete or heat-reflective surfaces. These can overheat the root zone, cause poor drainage, and slow plant development.

While the naturally low humidity of this climate helps reduce mold risk, the intense sun can quickly dehydrate plants. Water deeply in the early morning so roots can absorb moisture before peak heat, and apply a thick mulch layer to insulate the root zone and slow evaporation. If temps remain above 90°F for long stretches, use white shade cloth during the hottest hours to reduce heat stress without blocking essential light. Avoid black shade cloth, as it traps and radiates heat, worsening conditions.

Even in arid conditions, pests can still pose a threat, and sudden humidity spikes from storms can cause mold in long, resin-heavy colas. Keep airflow strong, monitor plants regularly, and spray Holi Moli Eliminator from veg through flower to protect against mold, mildew, bud rot, and pests. Safe for the full plant life cycle, it’s a must for keeping your harvest looking and smelling top-shelf.

How to Grow Black Princess Marijuana in Temperate Climates

This sweet, exotic terpene powerhouse can perform exceptionally well in temperate climates, but it needs extra attention to manage seasonal humidity, fluctuating temperatures, and late-season rain.

For the best start, germinate seeds indoors in early spring, then transplant outdoors once nighttime temperatures consistently stay above 50°F. This gives your vigorous, high-yielding cultivar a head start before it faces the unpredictable swings of a temperate season.

Choose a bright, open grow site with 8–10 hours of direct sunlight daily and consistent natural airflow. Good circulation helps keep the canopy dry and reduces the risk of mold in the elongated, resin-rich colas. Avoid planting near fences or walls, as they can trap humidity, block airflow, and cast unwanted shade—slowing growth and encouraging mold.

Opt for fabric grow bags over plastic pots— fabric allows better root aeration, improves drainage, and helps regulate soil temperature, while plastic can trap heat and moisture, creating stress during shifting seasonal weather.

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

Avoid setting grow bags directly on concrete or heat-reflective surfaces, as these can radiate heat into the root zone, limit drainage, and slow growth.

This tall, resin-coated lady is susceptible to mold in humid or rainy weather. Prune lower branches, thin the canopy for airflow, water early in the morning so leaves dry before nightfall, and mulch around the base to maintain steady soil moisture. If rain is forecast late in the season, use a rain cover or simple greenhouse to protect the long colas from prolonged wetness.

Even with moderate resilience, it benefits from preventative care. Apply Holi Moli Eliminator from veg through flower to guard against mold, mildew, bud rot, and pests. Safe for the entire plant life cycle, it’s a vital step to ensure your harvest finishes with top-shelf quality and aroma.

How to Grow Black Princess Indoors | Complete Guide

This trichome-coated beauty thrives in a stable, warm environment. Keep daytime (lights-on) temps between 75–80°F and nighttime (lights-off) temps between 65–70°F. Avoid large temperature swings, as big fluctuations can stress plants, slow development, and reduce bud quality.

During the vegetative stage, maintain 60–65% RH to encourage lush foliage and strong root growth. Once flowering begins, gradually lower humidity to 45–50% to help prevent mold from forming in the long, resin-coated colas. In the final two weeks before harvest, reduce RH further to 40–45% to lock in terpene flavor and improve bud density.

Use fabric grow bags instead of plastic pots— fabric allows better root aeration, improves drainage, and keeps soil temperatures stable under lights. For most setups, 5–7 gallon fabric pots work best. Allow 2.5–3 feet between plants to ensure proper airflow and avoid overcrowding.

This tall, vigorous sativa responds well to training. If you have experience or want to test your skills, topping, low-stress training (LST), or running a SCROG net can help manage height, improve light penetration, and increase yields. If you’re new to training, start with gentle LST and light defoliation until you’re comfortable with more advanced methods.

Expect a bold tropical fruit-and-spice aroma in bloom, so a carbon filter is a must for indoor grows. Pair it with oscillating fans to move air evenly through the canopy and a dehumidifier to manage moisture—especially during late flower when long, heavy colas are most at risk for mold.

Lighting plays a huge role in how this sativa-dominant beauty finishes. Full-spectrum LEDs deliver the best results. Some growers veg under 6500K and switch to 3000K–3500K for flower, but our growers here at Holi Moli have consistently achieved outstanding results keeping plants under 6500K from start to finish—producing tall, resin-packed colas with vibrant aroma and exceptional bag appeal.

Avoid skimping on lighting. Underpowered or low-quality fixtures can result in airy buds, reduced resin production, and muted terpene profiles. If you’re aiming for heavy yields and premium-quality flower, strong, efficient lighting is one of the smartest investments you can make—it can truly make or break the grow.
