Dutch Pro Amino Strength - Organic Amino Acid Stress Support
Best for: growers who want to help plants recover from heat, transplant or general feeding stress and push stronger flowering.
Our thoughts
This is the kind of additive that earns its place quietly — you won't see dramatic overnight changes, but plants running amino support tend to bounce back faster from the knocks every grow throws at them: heatwaves, transplant shock, heavy feed weeks. It's a genuinely organic formula rather than a synthetic PGR dressed up as one, which matters if that's important to you.
Dutch Pro Amino Strength is a 100% organic amino acid additive containing 18 of the 20 amino acids plants use, including glutamic acid, glycine, proline, arginine and lysine. It carries an NPK of 0-0-2, so the nutritional contribution is minimal by design — this isn't a feed replacement, it's a supporting product that helps plants build proteins, transport nutrients and manage stress more efficiently. It contains no plant growth regulators (PGRs), just amino acids sourced from natural, organic raw material.
It's suitable across hydroponics, soil and coco substrates, and is generally used to support plants through periods of stress — heat spikes, transplanting, heavy feeding, or the stretch into flower — rather than as a constant, every-feed additive.
How it compares
It's part of a small field of dedicated amino-acid additives that sit alongside a grower's main feed schedule rather than replacing any part of it.
- House & Garden Amino Treatment covers similar ground with amino acids plus added silicon for stalk strength — Dutch Pro's formula skips the silicon and focuses purely on the amino acid profile.
- BioBizz Alg-A-Mic leans more on seaweed extract with amino acids as a secondary component, and is more commonly used as a foliar tonic — Amino Strength is formulated as a root-zone feed additive with a broader amino acid spread (18 of 20).
- Amino Strength is built to slot directly into the wider Dutch Pro range, so it doses cleanly alongside their base nutrients if that's what you're already running.
None of these are direct substitutes for each other — the choice mostly comes down to whether you want silicon included, a foliar-style tonic, or a dedicated broad-spectrum amino product like this one.
Usage guidance
Amino Strength is a low-dose additive, so a little goes a long way.
Dosage
Use at 0.4ml per litre of feed or reservoir water.
When to use it
Bring it in during periods of stress — after transplanting, during a heatwave, through unusually heavy feed weeks, or around the stretch into flower — rather than running it on every single feed.
Compatibility
Works alongside hydro, soil and coco setups, and mixes into your existing feed schedule without needing to adjust your base nutrient dosing.

Who this is for

- Anyone transplanting between mediums or containers who wants to reduce recovery time.
- Dutch Pro users completing their existing feed line.
- Growers wanting an organic, PGR-free option for plant stress support.
Our take
Amino Strength is a targeted, organic support product rather than an everyday feed — dose it when your plants are under pressure and it earns its keep. The broad amino acid spread and PGR-free formula make it a straightforward, low-risk addition to any feed schedule.
Proper kit at a price that makes sense for growers who want their plants to shrug off the rough patches instead of stalling.
