How to Grow Blue Haze Marijuana Indoors and Outdoors

What to Watch for When Growing Blue Haze - It offers moderate resistance to mold, mildew, and pests, but because the buds get heavy and sticky, you’ll want to keep airflow strong and humidity in check, especially in the last few weeks of flower. Holi Moli Eliminator is also a solid option to spray preventatively during bloom.

Temperature Swings: This beauty prefers stable temperatures. It can tolerate light fluctuations, but big drops below 60°F at night or spikes over 85°F during the day can stress the plant and affect terpene production. If you're growing outdoors, make sure it's in a sunny, breezy spot with good airflow. Indoors, keep your temps in the 72–80°F range during lights-on, and around 65–70°F at night.

Nutrient Sensitivity: It isn’t super sensitive, but it doesn’t like being overfed—especially with nitrogen during flower. Overdoing it can lead to clawing or muted flavors. Use a clean cannabis-specific nutrient like Holi Moli Juice, monitor your pH, and avoid throwing too many additives at it.

Odor Control: Yes, odor control is needed. This strain puts out a loud aroma—sweet berry, earthy haze, and a little diesel kick. If you’re growing indoors and don’t want the whole house to smell like your tent, install a carbon filter before week 4 of flower.

Flowering Stretch: This hybrid does stretch when flipped to flower—usually 1.5x its veg height. It’s not extreme, but if you’re working with limited vertical space, flip to 12/12 around 20–24 inches tall (usually week 5–6) to stay ahead of the stretch. Training techniques like LST or SCROG can help keep the canopy even and increase bud sites if you’re more experienced.

Support: It grows tall with long side branches that can get heavy in late flower. Around week 3 of bloom, add light support like bamboo stakes or plant ties to prevent sagging or snapping. A little backup goes a long way toward protecting your yield.

Best Climate to Grow Blue Haze Cannabis

This fruity, uplifting hybrid thrives in warm, dry climates where it can bask in full sun and develop its signature berry-spiced aroma without battling excess humidity. For the best results, choose a sunny, open grow site where your plants can soak up 6–8+ hours of direct sunlight daily. A steady natural breeze is a big bonus — it helps keep airflow moving through the canopy and reduces the risk of mold as the buds fatten up.

To manage humidity outdoors, water early in the morning so any excess moisture can dry before nightfall. Add mulch around the base of your fabric grow bags to help retain soil moisture while keeping humidity low near the buds.

Prune the lower branches early in veg to improve airflow through the bottom half of the plant and reduce the risk of mold as flowers begin to bulk up. It’s also smart to keep Holi Moli Eliminator on hand and use it preventatively — especially if humidity spikes or wet weather rolls in.

Use fabric grow bags on well-draining soil — not on concrete or hot surfaces — to protect root health and prevent heat stress.

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 (ideal if you're letting your plants hit their full potential)

How to Grow Blue Haze Marijuana in Subtropical Climates

This potent strain can be successfully grown in hot, arid subtropical climates—but you'll want to take a few extra steps to protect your plants from heat stress and manage low humidity levels.

Start by using fabric grow bags, which allow for better airflow to the roots and help keep the root zone cooler than plastic containers. Always place your bags on well-draining soil, not concrete or heat-retaining surfaces. Set your plants in a sunny spot that also benefits from a gentle, steady breeze to keep the canopy ventilated.

Water early in the morning so your plants can absorb moisture before the sun hits hard. A thick layer of mulch around your fabric grow bags will help retain that moisture while keeping the soil cool — a game-changer in intense heat.

If temps consistently climb above 90°F, hang a white shade cloth during peak sun hours to reduce heat stress without blocking all that essential light. Prune the lower branches early in veg to boost airflow through the bottom of the plant, which helps prevent mold as the buds start to swell.

And to stay ahead of any issues, keep Holi Moli Eliminator on hand as a go-to preventative against mold, mildew, and pests. A few smart moves early on can make a huge difference come harvest time.

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 Blue Haze Marijuana in Temperate Climates

This blueberry-infused haze favorite can definitely be grown in temperate climates — but you’ll want to stay ahead of humidity and cooler nights, especially during late flower when the buds get dense and sticky. Start by germinating your seeds indoors if nighttime temps still dip below 50°F, and transplant them outside once the weather stabilizes.

Use fabric grow bags to help with drainage and root aeration, and place them on well-draining soil or gravel — not directly on damp or cold ground. Choose a sunny, open spot with steady natural airflow to keep moisture from building up around the canopy.

Water early in the day so the excess dries out before evening, and mulch around the base to retain soil moisture without raising ambient humidity. Prune the lower branches early in veg to open up airflow and reduce the risk of mold. Keep Holi Moli Eliminator on hand and spray preventatively during flowering, especially if rain or fog rolls in.

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 Blue Haze Indoors | Complete Guide

During the lights-on cycle, keep temperatures in the 72–80°F range. When the lights are off, let it dip slightly to around 65–70°F. This strain prefers stable temps, so avoid large swings — especially drops below 60°F, which can slow growth or cause stress in flower.

In vegetative stage, aim for 55–65% humidity. Once you flip to flower, gradually lower it to 40–45% by mid-bloom. During the final 1–2 weeks before harvest, drop humidity to around 35–40% to help prevent mold.

Use 5–7 gallon fabric pots for most indoor grows — they allow for solid root development while maintaining good airflow and drainage. If you’re going for larger yields and have the space, 10-gallon pots can give your plants room to really branch out. Space your plants about 18–24 inches apart to prevent overcrowding and ensure strong airflow throughout the canopy.

It responds really well to training, especially if you want to control height or maximize yield. If you’re experienced or ready to experiment, use LST (Low-Stress Training), topping, or SCROG methods to shape your plant early in veg. These techniques help increase bud sites, manage the stretch, and improve overall light penetration.

Yes — you will need odor control. This resin-rich beauty has a strong, sweet-berry-meets-haze aroma that ramps up fast around week 4 of flower. Use a carbon filter to keep your space discreet. Add oscillating fans above and below the canopy to prevent moisture pockets and reduce the risk of mold. If you’re in a sealed room or live in a humid area, a dehumidifier is also highly recommended — especially during late flower.

Lighting plays a huge role in your final results. This strain thrives under strong, full-spectrum LED lights. Most growers use 6500K for veg and switch to 3000K or 3500K for flower, but here at Holi Moli, we run 6500K from start to finish — and it works wonders. Expect denser buds, higher potency, and richer terpene profiles when you invest in quality lighting. The better the lights, the better the buds — plain and simple.
