Alga Bloom. By Plagron. 

Indoor growing, for all its cleverness and control, often runs into one colossal stumbling block: soul. And I don’t mean music. I mean the stuff in your soil that makes plants feel like they’re part of nature instead of a lab experiment. That’s precisely where Plagron Alga Bloom charges into the fray. This isn’t your average bottle of flowering feed. This is a 100% organic, algae-based nutrient, designed specifically for soil-based cultivation by the Dutch gurus at Plagron. And whether you're in a cupboard with a single pot or running a full-scale horticultural operation, this is the sort of product that reminds your plants what it means to be alive.

Less Stress. More Flowers. 

What sets Plagron Alga Bloom apart isn’t just that it’s organic - it’s that it works. Certified by Control Union and loaded with bioactive compounds, this nutrient isn’t trying to cheat nature, it’s working with it. The algae extracts aren’t just a gimmick. They bring amino acids, proteins and complex organic molecules that actually do something. We’re talking about faster nutrient uptake, stronger plant structure, improved resistance to temperature swings and drought stress, and - most importantly - more flowers. Bigger ones. Healthier ones. The kind of blossoms that make you stop and say, “Ah yes, now that’s a proper result.”

Increased Flavours.

Technically speaking, Plagron Alga Bloom is a balanced NPK 3-2-5 fertiliser, tilted perfectly for the flowering stage. The nitrogen keeps the engine ticking over, while the phosphorus kicks root development into gear and the potassium firms up the plant’s structure and flavour potential. This isn’t just a yield enhancer, it’s a quality enhancer too. And because it’s organic, the nutrients don’t flood your medium like a chemical torrent. They’re gently released via microbial activity in the soil - exactly how plants evolved to absorb them in the first place.

No More Nutrient Lockout.

One of the biggest headaches for indoor growers is pH stability. Nutrient lockout is the stuff of nightmares, and pH drifts are the culprit more often than not. Plagron Alga Bloom neatly sidesteps this with its built-in pH buffering. It naturally stabilises the substrate, helping to prevent wild swings in acidity that can send your feeding schedule into chaos. It’s the difference between constantly firefighting deficiencies and letting your plants just get on with the business of growing.

Super Concentrated. Lasts for Ages. 

Let’s also not forget that Alga Bloom doesn’t just feed your plants - it feeds your soil. The organic base improves soil structure, making it more aerated, better at retaining water, and more hospitable to beneficial microbes. Healthier soil equals healthier roots, and healthier roots lead to… well, you know where this is going. It’s a full-circle system where everything supports everything else, and the result is growth you can rely on week after week.

Big Flavours. Puncy Aromas.

Finally, the practicalities. Plagron Alga Bloom is highly concentrated - up to 4ml per litre is all you’ll need. It’s available in five different sizes, so whether you're testing the waters or swimming in deep, there's a bottle that fits. It integrates seamlessly with the rest of the Plagron range and makes an ideal choice for any grower who’s serious about high yields, superior taste, and building a garden that’s as resilient as it is productive. If you're looking to grow with power, purity and purpose, Plagron Alga Bloom is where you start.
