B-45 Feminized Seeds by Silent Seeds – 30%+ THC, Citrus-Creamy Flavor & High Yield Indoors/Outdoors

B-45 feminized seeds by Silent Seeds deliver a premium cannabis experience defined by extreme potency, complex flavor, and reliable high yields—making it a top choice for both seasoned growers and flavor chasers.

Feeling like your current strain just doesn’t hit hard enough or lacks that next-level depth in flavor? You’re not alone. Many end up with buds that smell generic, taste flat, and deliver underwhelming effects—wasting time, space, and effort.

That lack of intensity doesn’t mean you’re a bad grower. It often means you’re working with average genetics. When your plant doesn’t express rich terpenes or fails to pack a punch, it’s easy to think the problem is your setup—when really, it’s the seed. And that gap between expectation and reality kills motivation fast.

The solution? Start with a seed bred for excellence. B-45 isn’t just another hybrid—it’s a trophy-winning powerhouse developed in collaboration with French rap icon Booba. With a THC level hitting 30–32%, a citrus-creamy flavor profile that evolves into milky, cheesy depth, and dense, trichome-covered buds, this strain turns good grows into legendary ones. It’s built for performance, stability, and sensory impact—indoors or outdoors.

How to grow B-45 feminized seeds

Get the most out of your B-45 grow with this expert-backed guide—designed for quality, yield, and flavor.

Quick overview

Feminized photoperiod strain from Silent Seeds. 58–65-day flowering, low-to-medium difficulty, ideal for indoor tents or outdoor gardens in temperate climates.

• Indica-dominant hybrid with strong structure and high resistance
• Best grown in 18–25 L pots for maximum yield
• Use a well-aerated soil or coco mix for optimal root development

Safe start

Begin strong with healthy germination and early root support.

• Germinate seeds at 22–25 °C with high humidity
• Transplant once the taproot reaches ~1 cm (0.39 in)
• Use a light, airy starter mix to prevent damping off
• For a hassle-free start, Bio Bloommastic speeds up rooting and reduces transplant stress

Directed growth

Shape your plant early for better light penetration and yield.

• Switch to 18/6 light cycle to promote strong vegetative growth
• Apply low-stress training (LST) to create an even canopy
• Top once during early veg to encourage lateral branching
• In sustained growth, HESI Hydro Bloom keeps leaves green and structure compact

Efficient flowering

Maximize resin and density during the critical bloom phase.

• Switch to 12/12 light cycle to trigger flowering
• Maintain humidity at 40–50% to prevent mold
• Support heavy colas with stakes or a SCROG net
• At the end of flowering, Kit Biocanna helps with density and a cleaner taste

Harvest and refinement

Time it right for the perfect balance of effect and flavor.

• Harvest when 70–80% of trichomes turn milky to amber
• Flush plants 7–10 days before harvest to improve smoothness
• Dry buds slowly at 18–22 °C and 50–60% RH for 10–14 days
• Cure in jars for 2–4 weeks, burping daily to enhance flavor

Yes, it has a medium to high odor profile—especially during late flowering. Use a carbon filter if growing in a discreet space.

Can I grow B-45 outdoors in a colder climate?

Yes, it’s resilient to temperature fluctuations, but best suited for temperate to Mediterranean climates. Harvest before heavy rains to avoid mold.

Personal Experience of Pevgrow’s CEO (Alan)

I grew B-45 in my 1.20 m x 1.20 m (3.94 ft x 3.94 ft) tent with a 600W LED. I used 20 L pots and a soil mix with perlite for aeration. I topped each plant once at week 2 of veg and used LST to spread the canopy. The stretch was moderate—about 2x height—so I didn’t need to worry about hitting the lights. Flowering started strong, and by week 4, the smell was already citrusy and rich. I added Bio Bloommastic early and switched to Kit Biocanna in late bloom. The buds came out rock-hard, glistening with trichomes. After curing for three weeks, the flavor was insane—creamy lemon cake with a spicy kick. The high hit fast and lasted for hours. This one’s a keeper.
