Twenty-five years ago, Advanced Nutrients® changed the game with Big Bud®. It became the most popular bloom booster in cannabis cultivation, used by growers in 128+ countries and recognized with more industry awards for boosting cannabinoids, terpenes, and flower weight than any other nutrient on the market.
Today, we’re proud to announce the product built to carry that legacy forward. Advanced Nutrients Elite Series BGR™ (Bigger Buds) is officially available for order in the USA as part of the 8th-Generation Elite Series – and it builds on Big Bud to deliver a new level of bloom-phase performance. We’re actively working on making it available worldwide soon.
Why BGR Matters Right Now
The cannabis market has a quality problem. Dispensary shelves are packed with mid-grade flower that competes on price, not desirability.
Consumers face endless options and walk away underwhelmed. Wholesale prices keep compressing, margins keep shrinking, and cultivators producing average product are trapped in a race to the bottom that nobody wins.
In every mature market, the middle collapses first. There are only two sustainable paths forward: cheap and forgettable, or top-dollar and irreplaceable.
BGR was engineered for cultivators who choose the second path – those who understand that premium flower commands premium pricing, builds brand gravity, and creates the kind of repeat customers who come back specifically for your product.
Built on Big Bud. Engineered Beyond It.
Let’s be clear: BGR is not a replacement for Big Bud. Big Bud remains available and continues to deliver the results growers worldwide have relied on for twenty-five years.
What BGR represents is an evolution – the culmination of everything our scientists learned from Big Bud, refined through years of additional cannabis-specific research and development, and enhanced with proprietary technologies that simply didn’t exist until now.
As the 8th-generation Big Bud, Advanced Nutrients Elite Series BGR maintains the same proven 0-1-3 NPK ratio that made Big Bud legendary. That precision PK balance was never broken – so we didn’t fix it. Instead, we built around it, adding two breakthrough ingredients that elevate what a bloom booster can do.
Inside the Formula: Aminome™ and NanoCarb™
BGR’s dual-action formula introduces two scientifically engineered components developed specifically for cannabis:
Aminome™ – The Cleanest Amino Acid Complex Available
Aminome delivers all 20 key amino acids in a complete complex optimized for maximum metabolite production in cannabis.
Unlike generic amino products simply repackaged from general agriculture for the cannabis market – which are often dirty, inconsistent, and prone to clogging drip systems – Aminome™ is engineered with elevated concentrations of the specific aminos that drive cannabinoid synthesis and terpene development. It fertigates clean through even the most sensitive commercial irrigation setups.
NanoCarb™ – Breakthrough Nanotechnology for Direct Sugar Uptake
Here’s a problem most growers don’t realize they have: conventional sugar and carbohydrate products contain molecules that are too large for plants to actually absorb.
Their only real function is feeding microbes in the substrate. NanoCarb™ shatters that limitation. These nanosized carbohydrates are absorbed directly into plant tissue, maximizing brix levels to fuel resin production, enrich flavor profiles, and intensify the nose of your finished flower. This is bioavailable sugar delivery that actually reaches the plant – not just the soil around it.
How BGR Improves Plant Performance
When you integrate Advanced Nutrients 8th-Generation BGR into your bloom protocol, you’re adding a precision tool that works on multiple fronts simultaneously:
- Amplified terpene profiles. Aminome™’s cannabis-optimized amino blend provides the building blocks your plants need to synthesize terpenes at elevated levels. The result is flower with rich, complex aroma and flavor that stands out on any shelf.
- Intensified resin production. NanoCarb™ drives brix levels higher by delivering bioavailable sugars directly into plant tissue, fueling the resin output that translates to stickier, frostier buds with serious bag appeal.
- Increased yields and flower density. The combined effect of a complete amino complex and direct sugar uptake means your plants have the resources to pack on weight and density during the critical bloom phase.
- Enhanced cannabinoid production. The amino acid profile in Aminome™ is specifically weighted toward the metabolic pathways responsible for cannabinoid synthesis, supporting potency alongside weight and terpenes.
- Clean fertigation performance. BGR flows effortlessly through any irrigation system, including sensitive commercial drip setups. No clogging, no buildup, no maintenance headaches.
27 Years of Cannabis Science in Every Bottle
BGR isn’t a product that was rushed to market. It’s the product of 27 years of cannabis-specific research, over $3 million in 8th-Generation development investment, and the kind of scientific infrastructure that no other nutrient company in the industry can match.
Advanced Nutrients holds one of the first government-issued licenses to grow cannabis for research purposes. Our team of PhD plant scientists has studied nutrient uptake, metabolite production, and bloom-phase optimization across tens of thousands of plants and hundreds of genetic varieties. BGR represents the latest application of that deep research base – and it shows in the results.
The 8th-Generation Elite Series is already delivering measurable outcomes at top facilities: 4-4.5+ pounds per light, terpene profiles reaching 5+%, and cultivators commanding $200-$300+ more per pound because the quality difference is undeniable.
How to Use BGR
Advanced Nutrients BGR is designed to integrate seamlessly into your existing bloom protocol:
- Application rate: 2 mL per liter
- Timing: Begin in week 2 of bloom and continue until flush. (If you prefer a later bloom enhancer introduction or run a longer flower set, week 3 is also effective.)
- Nutrient solutions: Mix a fresh reservoir weekly.
- Coco: Apply daily.
- Other substrates: 2-4 times per week as necessary.
Shake well before use. BGR is compatible with all growing media and integrates with any fertigation protocol – from advanced hydroponic systems to traditional soil-based setups.
Frequently Asked Questions
What is BGR’s NPK ratio?
BGR maintains the proven 0-1-3 NPK ratio that made Big Bud the world’s leading bloom booster. This golden balance was fine-tuned through extensive cannabis-specific R&D to deliver optimal bloom nutrition without excess phosphorus.
How does BGR differ from Big Bud?
BGR keeps Big Bud’s proven PK ratio and builds on it with two proprietary technologies: Aminome™ (clean-running amino complex) and NanoCarb™ (bioavailable carbohydrates). The result is a cleaner-running, higher-performing bloom booster that takes the proven Big Bud foundation to a new level. Big Bud remains available for growers who prefer it – BGR is the next step for those ready to push further.
Is BGR compatible with my irrigation system?
Yes. BGR was specifically engineered for clean fertigation. Aminome™’s ultra-clean amino complex flows through even the most sensitive drip systems without clogging or buildup. Whether you’re running commercial drip irrigation, flood-and-drain, DWC, or hand-watering in soil, BGR integrates without compatibility concerns.
What growing media can I use BGR with?
BGR works across all growing media: coco coir, rockwool, peat-based substrates, soil, and hydroponic systems. Application frequency varies by media – daily for coco, 2-4 times weekly for other substrates – but the formula is universally compatible.
When and how do I apply BGR?
Apply 2 mL per liter beginning in week 2 of bloom (or week 3 for longer flower sets) and continue until flush. Shake well before use and mix fresh reservoirs weekly. BGR integrates into your existing feeding schedule without requiring protocol adjustments.
Does BGR come with a guarantee?
Absolutely. Like every Advanced Nutrients product, BGR is backed by our 100% Money-Back Grower Guarantee. If you aren’t completely satisfied with your results, return the unused portion with your original sales receipt to your authorized place of purchase within six months for a full refund.
