Alga Grow. By Plagron. 

There comes a time in every grower’s journey when they realise it’s not about chucking as many bottles of chemicals at a plant as possible. It’s about feeding them the right stuff, at the right time, in the right way. That’s where Plagron Alga Grow steps into the spotlight. This is not just another bottle of green liquid shouting empty promises. This is a proper, purpose-built, algae-based base nutrient designed specifically for the growth phase of soil-grown plants. And it’s organic. Certified organic, in fact – not just some vague claim slapped on a label for marketing fluff.

Grow Big. Grow Beautiful Grow Organic.

Let’s talk about what Plagron Alga Grow actually does. First off, it nourishes your plants during the most critical stage of their life cycle – the vegetative phase. That’s when roots need to go deep, branches need to thicken, and foliage needs to explode in every direction. If you get this bit wrong, it doesn’t matter how good your flowering boosters are later on – you’ll be stuck with a plant that’s structurally unsound, nutrient deficient, and generally sulky. Alga Grow ensures this doesn’t happen by delivering a balanced mix of macronutrients, micronutrients, and amino acids straight to the source.

Premium Nutrition. Tastier Plants.

And here's why it’s so brilliantly simple. Plagron Alga Grow is completely organic, so you don’t need to faff around with EC meters or constant pH adjustments. It’s tailored for soil, and once it’s in, it helps the substrate do the heavy lifting. The organic components – including proteins and amino acids – feed the microorganisms in your soil, which in turn help your plant absorb nutrients more efficiently. It’s like upgrading your plant’s internal plumbing. Everything flows better. Everything works faster. Everything gets bigger.

Loaded with Organic Goodness.

One of the real secret weapons inside Plagron Alga Grow is algae – not just a trendy buzzword but a powerhouse of bioavailable nutrition. Algae-based feed is absolutely loaded with plant-usable nitrogen and trace elements, which fuel cell division and boost foliage development without scorching or stressing the roots. It’s also naturally rich in vitamins and hormones that promote root branching and reduce transplant shock. For anyone setting up cuttings or transplanting young plants into their final pots, this stuff is liquid gold.

Breathtaking Aroma & Flavour. 

And if you’re worried about the occasional strange smell or bit of cloudiness, don’t be. That’s not contamination – it’s biology. Organic products are meant to look and smell like they’ve come from the natural world, not a sterile laboratory. Plagron Alga Grow works best when it’s paired with other Plagron products like Power Roots, but on its own, it already gives your plants everything they need to build a bulletproof frame.

Simple to Use. Hard to Overlook.

What really sets Plagron Alga Grow apart, though, is how easy it is to use. Up to 4ml per litre, shaken well, applied with every watering during veg – and that’s it. No spreadsheets, no chemistry degrees required. And with six sizes available, from discreet cupboard growers to full-on fruiting fanatics, there’s a bottle that fits every scale and ambition.

So if you're after fast, strong, stress-free growth without all the complications of synthetic nutrients, Plagron Alga Grow is the base feed you’ve been looking for. It’s clean, it’s clever, and it’s crafted by Dutch growers who know their stuff. Because in the world of indoor gardening, good roots mean good shoots – and Alga Grow makes sure you get both.
