Cali Pro Grow A & B. By Emerald Harvest. 

When it comes to the vegetative stage of plant development, there are two types of growers: those who feed their plants, and those who build them. If you fall into the latter camp, then Emerald Harvest Cali Pro Grow A & B is your new secret weapon. This isn’t a vague all-purpose fertiliser designed to cover up bad habits.

This is a precision-engineered formula born in the horticultural heartlands of California, built by growers who understand that a good start is everything. And it doesn’t matter whether you’re growing in a high-tech hydro lab or a converted airing cupboard - this is premium feed for premium results.

A Growth Spurt in a Bottle. 

The backbone of Emerald Harvest Cali Pro Grow A & B is nitrogen. -lots of it, and for good reason. Nitrogen is the element that fuels vegetative growth. It stimulates the production of chlorophyll, which, in plain terms, is the plant's way of turning light into life.

More nitrogen equals more leaves, more branches, and more biomass, all of which lay the structural foundations for a plant that’s going to support serious flowering later on. With a guaranteed NPK analysis of 3-0-0 in Part A and 2-2-5 in Part B, Cali Pro Grow delivers a controlled surge of nitrogen exactly when your plants need it most.

Two Part Set.

But nitrogen alone doesn’t cut it - not if it’s locked up in a formula that your plants can’t absorb properly. That’s where Emerald Harvest Cali Pro Grow A & B steps ahead of the pack. Every bottle contains premium chelated minerals, and if you’ve never heard of those, here’s the translation: it means nutrients are wrapped in a molecular hug that makes them much easier for roots to absorb.

This is especially useful in hydroponic setups, where nutrient availability and uptake efficiency make or break a grow. These chelated forms mean fewer deficiencies, faster uptake and healthier plants all round.

Premium Chelated Minerals.

Now, if you've ever battled with pH drift, you’ll know how frustrating it is to mix a perfect solution, only to have the nutrient balance collapse because your pH shifted by half a point. Emerald Harvest Cali Pro Grow A & B sidesteps that headache entirely.

Its chelated content makes nutrients available across a much wider pH range than standard formulas. That means even when your pH isn’t perfect, your plants can keep feeding happily - no lockout, no drama, just consistent, healthy growth day in and day out.

Super Easy To Use. 

One of the most impressive things about Emerald Harvest Cali Pro Grow A & B is how easy it is to use. You don’t need a PhD in botany or a spreadsheet of EC values to get started. Just add equal parts A and B to your feed water - never mix them concentrated - and you’re off.

Adjust your pH to somewhere between 5.8 and 6.3, and let the formula do the heavy lifting. Whether you’re growing in soil, coco, or a deep water culture system, the results are consistently spectacular, with thick stems, vigorous growth, and leaves that look like they’ve been polished.

Emerald is the New Gold Standard.

Lastly, this isn’t some generic nutrient mix from a nameless lab. This is Emerald Harvest Cali Pro Grow A & B, developed by experts who live and breathe indoor cultivation. It’s part of a comprehensive line trusted by thousands of professional growers worldwide, and with good reason - it works.

From small stealth grows to warehouse-sized setups, Cali Pro Grow has earned its reputation as a dependable, high-performance base nutrient that delivers results you can actually measure. If the flowering stage is your harvest, the vegetative stage is your investment - and this is one feed worth every drop.
