Bloom. By Emerald Harvest. 

There are two types of growers in the world: those who guess their way through the flowering stage, and those who use Emerald Harvest Bloom. If you’ve ever looked at your crop and thought, “Why aren’t these flowers the size of tennis balls?” the answer is probably phosphorus. Or rather, the lack of it. That’s where Emerald Harvest Bloom comes in – a turbocharged PK formula engineered in California by growers who’ve already made all the mistakes so that you don’t have to.

Giant, Dense Flowers.

At the heart of Emerald Harvest Bloom is a finely tuned blend of monopotassium phosphate, potassium sulphate, and magnesium sulphate. It might sound like a chemist’s shopping list, but trust me, this is the floral equivalent of a protein shake laced with rocket fuel. The phosphorus boosts plant tissue development, ensuring rapid flowering and fruit production. The potassium regulates water uptake and sugar transport. Meanwhile, magnesium and sulphur chip in to supercharge chlorophyll synthesis, giving you lush green foliage that doesn’t just look good - it functions at peak efficiency.

Powerful Flavours.

Unlike one-size-fits-all nutrient bottles, Emerald Harvest Bloom is designed to work in tandem with Emerald Harvest Grow and Emerald Harvest Micro. It’s part of a fully customisable three-part system that lets you adjust nutrient ratios throughout the entire grow cycle. If your plants are showing dull, pale leaves or slow flower development, just dial up the Bloom and watch your garden transform. Think of it not as a fertiliser, but as fine-tuned control over your grow room’s potential, with phosphorus doing the heavy lifting during those all-important flowering weeks.

Made In California. 

One of the standout features of Emerald Harvest Bloom is its versatility. Whether you’re growing in coco, soil, rockwool, or deep in the world of recirculating hydroponic systems, Bloom dissolves easily and behaves itself in reservoirs. It’s stable, reliable, and doesn’t interfere with your microbial environment. It’s designed to support you from the seedling stage all the way through to the final ripening push. Used correctly, the changes become visible fast: denser clusters, richer colours, and a serious uptick in weight. Bigger fruits, tastier plants - because that’s the whole point, isn’t it?

Intense Aromas.

The science is sound. An NPK ratio of 0-5-4 ensures that there’s just the right amount of phosphorus and potassium without flooding your system with unnecessary nitrogen. Add to that 1% sulphur and 0.5% magnesium, and you’ve got a balanced cocktail of macro and secondary nutrients that target exactly what your plant needs when it needs it most. And it’s not just about making things bloom – it’s about making them flourish, packing on weight and flavour, and reaching maturity faster than you ever thought possible.

For the Flavour Hunters.

As with all things from Emerald Harvest, Bloom is developed by professionals who actually grow for a living. This isn’t corporate fluff. It’s horticultural engineering at its finest, tailored for those who want real results from their indoor grow. Available in two bottle sizes to match your ambitions, Emerald Harvest Bloom is the definitive answer to the age-old grower’s question: “How do I get more out of my plants?” The answer? Use Bloom, and let nature show off.
