Buddhas Tree Advanced Meta-Boost — Seaweed-Based Flowering Biostimulant for Enhanced Plant Metabolism
Best for: Growers wanting to boost plant metabolism and essential oil production during flowering without overcomplicating their nutrient protocol
Our thoughts
This does something different from your standard PK booster. Instead of just ramming phosphorus and potassium at your plants, Meta-Boost works on plant physiology itself — speeding up nutrient uptake, activating root-zone microbes, and triggering natural growth hormones. Smart piece of kit, and it pairs beautifully with PK 9-18 for a proper flowering protocol.
Buddhas Tree Advanced Meta-Boost is a seaweed-derived plant metabolic booster designed to enhance plant performance during the flowering phase. Rather than just adding raw nutrients, it actively stimulates your plants' own growth systems — increasing their ability to uptake what's already in your feed, activating beneficial microbes in the root zone, and triggering the natural plant hormones (auxins and cytokinins) that drive bigger, more fragrant blooms. Applied from week 4 of flowering through to flush, it works with any base nutrient and any growing medium, making it a genuinely flexible addition to your feeding schedule.
How it compares
Most flowering boosters are straight phosphorus-potassium plays. Meta-Boost takes a different angle.
-
vs. KoolBloom: KoolBloom is pure nutrient — high P-K delivered early in flower. Meta-Boost works on plant metabolism itself, making it better suited to the back half of flowering where efficiency matters more than raw input.
-
vs. Big Bud: Big Bud aims for harvest weight through macro ratios. Meta-Boost focuses on plant physiology and microbial activity, meaning you get better nutrient conversion rather than just nutrient volume.
-
vs. Bloombastic: Both are biostimulant-heavy, but Meta-Boost leans harder into seaweed-derived auxins and cytokinins, plus it's designed as a partner to PK 9-18 rather than a standalone.
In practice: Meta-Boost is the thinking grower's flowering additive. It works best paired with a dedicated PK booster, not instead of one.
Usage guidance
Application timing
Start at week 4 of flowering and run through to flush. Use 2–3mL per gallon, adjusting to the upper end if you're running a full flowering protocol with other Buddhas Tree products.
How to use it with other nutrients
Meta-Boost plays well with any base nutrient. For best results, combine it with Buddhas Tree PK 9-18 — the two products complement each other. The PK 9-18 handles the raw phosphorus-potassium demand; Meta-Boost ensures your plants actually convert and use it efficiently.
Across different systems
Works in hydroponics, drip-fed systems, and hand-watered soil setups without issue. The seaweed extract is stable across pH ranges and doesn't interact badly with other additives. Shake before use — the active compounds settle.
What it actually does
The seaweed contains naturally occurring plant growth hormones (auxins and cytokinins) that signal your plants to speed up cell division and energy metabolism. The amino acids give the plant the raw materials to produce vitamins, enzymes, and proteins faster. The betaine glycerine offers stress resilience if your environment gets a bit rough. Meanwhile, the microbe-feeding carbohydrates activate beneficial bacteria and fungi in the root zone, which protect roots and increase nutrient uptake. It's not magic — it's just intelligent plant biology.
Technical specifications
- Active ingredient: Seaweed extract (naturally rich in auxins, cytokinins, and amino acids)
- Additional components: Plant sugars, betaine glycerine, plant hormones, proprietary additives
- Dosage: 2mL/gallon during veg; 2–3mL/gallon from week 4 of flowering through flush
- Available sizes: 500ml, 1L, 5L bottles
- Shelf life: One year from opening
- Compatibility: Any base nutrient, any growing medium, any system type
Who this is for
- Growers moving beyond basic feeding and wanting to understand plant physiology
- Anyone already using Buddhas Tree PK 9-18 and looking to maximise that investment
- Experienced growers chasing higher-quality blooms without guessing at nutrient concentrations
- Hydro and drip-fed systems where nutrient efficiency directly impacts yield
- Growers in less-than-ideal conditions who need plants to perform harder with less environmental headroom
Particularly suited to anyone who understands that bigger harvests aren't always about dumping more nutrients — sometimes it's about making the plant system work better with what it's got.
Our take
This is a proper piece of science applied practically. It does what it claims — speeds up plant metabolism, activates beneficial microbes, and triggers the hormonal signals that lead to better-performing plants during flowering. It's not a replacement for good base nutrients or a solid PK booster, but as a partner product in a thoughtful feeding schedule, it delivers.
Good time to buy while clearance stock lasts. Pairs brilliantly with PK 9-18, and if you're serious about your flowering results, it's worth the investment.
