Plagron Power Buds: a flowering-phase biostimulant
Plagron Power Buds is a liquid biostimulant that helps plants produce amino acids during flowering, speeding up the nutrition cycle that drives bud formation. You mix it into your watering schedule from the moment flowering kicks in. It's not a fertiliser and it doesn't shift your EC value, which is the bit that matters — you can drop it into an existing feeding regime without rebalancing everything else.
If you've grown with Plagron's Green Sensation or Sugar Royal before, think of Power Buds as the early-flower companion that gets the bud sites firing before the heavy bloom boosters take over. Plagron is a Dutch brand that's been making cultivation products since 1992, and Power Buds is one of their newer additions — designed specifically to push energy into flowers instead of stem growth, which keeps plants more compact and productive. You can buy it in three sizes depending on how much you grow.
Which bottle size to grab
Power Buds comes in three sizes — 100 ml, 250 ml, and 1000 ml — all with the same formula. Pick by garden size and how often you grow.
| Size | Covers roughly | Best for |
|---|---|---|
| 100 ml | Up to 100 litres of feed water | One small tent, single grow, or trying it out before committing |
| 250 ml | Up to 250 litres of feed water | Standard 80x80 or 100x100 setups, one full flowering cycle |
| 1000 ml | Up to 1,000 litres of feed water | Multiple tents, perpetual harvests, or commercial-scale grows |
Honest take: the 100 ml is the sensible starting point for a first-time user — you'll get through one full flowering phase on a small tent and still have a bit left. If you grow back-to-back or run more than one tent, order the 250 ml for better value. The litre bottle only makes sense if you're running serious volume. From our counter, most first-timers come back for the 250 ml on their second order — they realise they want it on hand for the next grow.
Why Power Buds belongs in your flowering toolkit
Power Buds fills the gap between healthy roots and dense buds by directing the plant's energy into flower formation rather than stem stretch. Flowering is the phase where every decision you made earlier either pays off or doesn't. Healthy roots, good light, dialled humidity — fine. But the plant still has to decide where to send its energy, and without a nudge, you'll get plants that keep stretching upward when you'd rather they bulked up sideways with bud sites.
By supporting amino acid production early in flowering, the plant runs its nutrition process more efficiently, which means more of what it's already taking in actually gets directed to flower formation. Plagron certifies it as a biostimulant, not a fertiliser — so it's working on plant signalling, not just adding more N-P-K to the mix. That's also why it doesn't bump your EC: you're not adding salts, you're adding a functional molecule.
The other practical win is compatibility. Because it's hormone-free and EC-neutral, you don't need to tear up your existing schedule. Keep your base nutrients, your bloom booster, your root stim — Power Buds slots in alongside without forcing you to recalculate anything. For growers who've spent months getting a feeding regime stable, that's the difference between "I'll try it" and "I'm not touching what works."
How to use Plagron Power Buds
Use Power Buds at a maximum of 1 ml per 1 litre of water, starting from the first week of flowering and continuing through the entire bloom phase. Specifically:
- Shake the bottle well before every use — the active molecule needs to be evenly distributed.
- Measure a maximum of 1 ml per 1 litre of water. Don't go over — more isn't better with biostimulants.
- Add it to your feed water from the first week of flowering, not before.
- Use throughout the entire flowering phase, not just the first fortnight.
- Combine with your normal base nutrients and bloom boosters as you would on any feeding day.
- Store the bottle in a cool, dark place between uses — biostimulants don't love heat or sunlight.

Pairs well with Plagron's base nutrients (Terra Bloom for soil, Hydro B for hydro setups) and with bloom boosters like Green Sensation in the second half of flowering. If you're building a Plagron-only schedule from scratch, get the Plagron feed chart with your order — it tells you exactly when each bottle goes in. Compared to running base nutrients alone, adding Power Buds from week one is the single change most growers notice in bud-site density.
From our counter
Most growers ask whether they really need another bottle on the shelf — and the honest answer depends on what they're seeing in week two. Most growers already have a base nutrient, a root stim, and a bloom booster. If your plants stretch too much in early flower or your bud sites look sparse at week two, this is the bottle that addresses that specific problem. If everything's already going perfectly, you don't need it. We've seen growers run identical genetics side by side, one with Power Buds added from week one, one without — the treated plants stayed shorter and packed in more flowering sites. Not magic, just a more efficient nutrition cycle.
Honest limitations
Power Buds will not rescue a struggling grow — it works on top of healthy plants, not in place of fixing the basics. If your light is weak, your humidity is wrong, or your roots are struggling, no amount of Power Buds will help. Also worth noting: because it's not a fertiliser, you still need a proper bloom-phase base nutrient. Don't read "boosts flowering" and assume this replaces your N-P-K — it doesn't.
Frequently Asked Questions
Can I only use Power Buds when I grow hydroponic?
No. Power Buds works in soil, coco, and hydroponic setups. The dosing stays the same — maximum 1 ml per 1 litre of water — regardless of medium.
Can I use Power Buds together with Green Sensation and Sugar Royal?
Yes. Power Buds is hormone-free and EC-neutral, so it stacks with other Plagron products without disrupting your feeding schedule. Power Buds runs through the whole flowering phase; Green Sensation and Sugar Royal come in during the bloom-boost window.
When exactly do I start using it?
From the first week of flowering — when you switch your light cycle to 12/12 or when your plant starts showing pre-flowers outdoors. Starting earlier doesn't help; starting later means you miss the early bud-site formation window.
Is Power Buds a fertiliser?
No. It's a biostimulant — it works on the plant's nutrition process by helping it produce amino acids. You still need a proper bloom-phase base nutrient alongside it.
Will it raise my EC value?
No. Power Buds does not affect EC, which is one of the reasons it's straightforward to add to an existing feeding regime. You don't need to recalibrate your nutrient mix.
What happens if I overdose?
Stick to the 1 ml per 1 litre maximum. Biostimulants don't follow a "more is better" logic — overdosing won't speed flowering up further and may stress the plant. Measure carefully and shake the bottle each time.
Where can I buy Plagron Power Buds in the Netherlands?
You can order Power Buds directly from Azarius. Plagron is a Dutch brand based in Weert, and stock typically ships the same working day if you order before the daily cut-off.
