Plagron Fish Force is your go-to organic growth booster, scientifically crafted to fuel fast, healthy development during the vegetative phase with visibly greener, stronger plants.

Are You Struggling to Get That Deep-Green, Jungle-Like Growth?

Let’s face it: not all growth boosters deliver on their promises. You’ve probably tried products that claim to supercharge your plants but end up doing little more than watering them down. Worse, some synthetic nutrients burn roots, throw off pH, or leave behind harmful residues.

Confusion, Smells, and Failed Results Are Holding You Back

There’s a lot of noise out there. Organic vs synthetic? Foliar spray or root feed? And what about that fishy smell—does it mean it’s working or just rotting in your reservoir? Many growers end up frustrated, wasting time and money on products that either don’t work or create more problems than they solve. Some even give up on organic growing altogether, thinking it’s too slow or weak.

Fish Force Delivers Real, Visible Growth—Naturally and Without the Hype

Plagron Fish Force cuts through the confusion. This isn’t lab-synthesized junk—it’s a powerful, natural formula made from fish emulsion and seaweed extract that plants actually recognize and absorb fast. You’ll see thicker stems, deeper green leaves, and a vitality that says “I’m thriving.” Use it weekly during veg, and you’ll build a robust foundation for massive yields later.

Common Myths About Organic Growth Boosters

  • Myth: Organic nutrients are too weak for serious growth. Reality: Fish Force delivers rapid, visible results thanks to its high nitrogen and amino acid content.
  • Myth: All fish-based fertilizers smell the same. Reality: The smell is natural and temporary—proof it’s alive and working, not synthetic.
  • Myth: Organic means slow results. Reality: Users report greener leaves within days and stronger growth within a week.
  • Myth: You can use it in hydroponics. Reality: No—its organic particles can clog lines. It’s designed for soil and coco only.
  • Myth: It’s just for outdoor use. Reality: It works great outdoors, but the odor makes it less ideal for indoor grows.

What Fish Force Really Does (And What It Doesn’t)

Fish Force is a targeted growth-phase fertilizer that floods your plants with the nitrogen, amino acids, and vitamins they crave when building stems, leaves, and roots. It boosts chlorophyll production for that signature deep green and strengthens plant immunity against stress and pests. It’s not a flowering booster, nor is it a root stimulator on its own—though it supports root health indirectly by feeding the soil microbiome.

It won’t eliminate the need for a full nutrient line, but it will make your base nutrients work better. And no, it won’t turn your grow room into a fish market if used correctly—but yes, you should avoid using it indoors if you’re sensitive to smells.

Advantages and benefits when used properly

  • Accelerates vegetative growth with natural, fast-absorbing nutrients
  • Produces intensely green, healthy foliage thanks to high nitrogen and chlorophyll stimulation
  • Strengthens plant resilience against diseases, pests, and environmental stress
  • Supports a thriving soil microbiome for long-term growing success
  • Safe for mother plants and clones—keeps them vigorous and productive
  • Easy to use: just 10ml per liter, once a week
  • Works as a foliar spray for rapid leaf absorption
  • Perfect for organic cultivation—no synthetic chemicals or residues

Tips to choose well according to your expectations

Not every grower is the same—and Fish Force isn’t for everyone. But if you’re aiming for lush, organic growth with real results, it’s a game-changer. Here’s how to know if it’s right for you:

  • If you expect fast, visible growth without synthetics → Fish Force delivers with natural power
  • If you grow in soil or coco → This is your ideal match
  • If you’re using hydroponics → Look for a liquid kelp or amino acid booster instead
  • If you grow indoors and hate smells → Consider alternatives like Pure Zym or Green Sensation
  • If you want to keep mother plants healthy → Use weekly for unbeatable vitality
  • If you’re new to organic growing → Pair it with Oidio Killer Agrobacteria and Natural Clone by Trabe for a complete organic system

Frequently Asked Questions

Can I use Fish Force in hydroponic systems?

No, Plagron Fish Force is not suitable for hydroponics. Its organic components may clog irrigation lines. Use it only in soil or coco substrates.

Is it safe for indoor growing?

Due to its strong, natural fish odor, it’s generally recommended for outdoor use. If you grow indoors, ensure excellent ventilation or consider less aromatic alternatives.

What’s the NPK ratio of Fish Force?

It has an NPK ratio of 3-6-2, making it nitrogen-rich—perfect for the vegetative phase.

How often should I apply it?

Use once a week during the growth phase. Shake well before each use.

Can I use it as a foliar spray?

Absolutely. Spray on both sides of the leaves for faster absorption and greener results in days.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve heard every excuse not to go organic: “It’s too slow,” “It doesn’t work,” “It smells like a bait shop.” I used to think the same—until I tried Fish Force on my test garden. I applied it weekly to a batch of Blue Dream in coco, and within a week, the difference was obvious: darker green, thicker stems, zero stretch. I even used it on mother plants, and their cuttings rooted faster and stronger. Yes, it smells—like the ocean, not a landfill. But outdoors? Zero issue. The real win is seeing how it works with the soil life, not against it. If you’re serious about organic growth that actually performs, this is your secret weapon. Just don’t use it in your bedroom grow tent—your roommate will revolt.
