Cali Pro Bloom A & B. By Emerald Harvest. 

If there’s one thing more frustrating than a flowering plant that just refuses to fill out, it’s one that pretends it’s doing well before giving up halfway through the bloom cycle. Enter Emerald Harvest Cali Pro Bloom A & B, the Californian-born powerhouse designed by actual growers who’ve seen every possible horticultural disaster. This isn’t just another two-part base nutrient. This is a meticulously engineered formula for anyone who’s serious about pushing plants through bloom with brute force finesse - whether they’re growing discreetly in a cupboard or running full-blown hydro operations the size of a supermarket.

Premium Nutrition for Massive Yields. 

What sets Emerald Harvest Cali Pro Bloom A & B apart is its unapologetic emphasis on the elements that matter most during flowering: phosphorus and potassium. These two nutrients aren’t just helpful; they’re critical. Phosphorus boosts energy transfer and metabolic processes, helping the plant break down its feed like a well-oiled digestive system. Potassium is responsible for photosynthesis and water regulation - vital if you want dense, heavy, well-structured flowers that don’t fold under their own weight. It’s the horticultural equivalent of a personalised training programme, with none of the fluff and all of the performance.

Two Part Set.

Of course, it’s not just about what goes in - it's about how efficiently it's used. Emerald Harvest Cali Pro Bloom A & B is formulated with premium chelated minerals, which are chemically bound in a way that makes them more bioavailable to roots. That means they’re easier to absorb, faster to take effect, and far less likely to cause the sort of deficiencies that make leaves go yellow and sad. Chelation is, in essence, the science of making your nutrients behave like they’ve got somewhere important to be - and getting there quickly.

Avoid Nutrient Lockout.

And then there’s the matter of pH. Any experienced indoor grower knows that pH drift is the invisible killer - creeping in slowly and silently wrecking nutrient uptake. But here’s the good news: chelated minerals don’t care quite as much about pH swings. Emerald Harvest Cali Pro Bloom A & B allows for greater absorption across a wider pH range, giving your plants a stable feed environment even if your meter’s having an off day. It’s not foolproof, but it’s damn close.

Super Easy To Use. 

What’s remarkable is how simple this all is to use. Equal parts A and B, measured out with all the ceremony of making a cup of tea. Mix it gently into your reservoir, don’t shake it like a cocktail, and let it do the hard work. Just make sure you’re using both parts - running with only A or B will lead to an unbalanced feed and results as predictable as a leaky tent in a thunderstorm. Used properly, it gives your plants every macro and micronutrient they could possibly need to put on serious size during bloom.

Emerald is the New Gold Standard.

So whether you’re running hydro, coco, or soil, in a sealed room or a converted loft, Emerald Harvest Cali Pro Bloom A & B is your answer to consistent, controlled, explosive flowering. This is no-nonsense nutrition for growers who expect results - and it comes with the Californian pedigree to back it up.
