Cali Pro Grow A+B – Emerald Harvest Base Nutrient · Explosive Vegetative Growth

Cali Pro Grow A+B by Emerald Harvest is the high-performance 2-part base fertilizer designed to provide your cannabis plants with the structural foundation and explosive energy they need during the critical vegetative phase.

Is your grow room falling short of its potential?

Are you tired of watching your plants struggle to gain mass, showing yellowing leaves or weak stems that look like they'll snap under the first sign of a bud? It’s frustrating to put in the hours and electricity only to end up with a mediocre canopy that lacks vigor. You know that a weak vegetative stage inevitably leads to a disappointing harvest, and guessing with generic fertilizers often results in nutrient lockouts or deficiencies that are a nightmare to fix.

Every day your plants spend struggling is a day of lost growth. Weak stems mean they won't be able to support heavy flowers later, forcing you to use endless stakes and supports. Plus, nutrient imbalances now can stress the plant, making it more susceptible to pests and diseases. Why risk your entire crop's potential on subpar nutrition when the solution used by pros is right here?

Cali Pro Grow A+B is the game-changer you need. This professional-grade formulation eliminates the guesswork, providing a precise balance of Nitrogen, Calcium, and chelated micronutrients. It turns your grow room into a high-efficiency factory, ensuring your plants build a rock-solid structure capable of supporting the massive yields you’re dreaming of.

How your grow changes with Emerald Harvest

Once you switch to this system, the difference is visual and immediate. Gone are the pale, spindly stems; instead, you'll see thick, sturdy stalks and vibrant, deep green leaves reaching for the light. It’s about creating a plant that is metabolically optimized to eat, grow, and thrive.

Using premium Cannabis fertilizers like Cali Pro simplifies your routine. You stop worrying about deficiencies and start focusing on training your plants for maximum yield. It’s the peace of mind that comes from knowing your girls are getting a 5-star meal every time you water them.

Why choose a 2-Part Nutrient System?

You might wonder why you need two bottles instead of one. Here is why this split format is superior for serious growers:

• Chemical Stability: Keeping certain elements separate (like Calcium in Part A and Phosphates in Part B) prevents them from reacting and precipitating in the bottle.
• Customizable Ratios: While it's designed to be used in equal parts, it allows for expert tweaking if specific strain needs arise.
• Maximum Absorption: The nutrients remain fully available to the plant roots immediately upon mixing with water.
• Versatility: Works perfectly in soil, coco coir, and hydroponic systems.
• Complete Nutrition: Covers all macro and micronutrients, reducing the need for a dozen different additives.

Steps to feed your plants like a Pro

1. Shake well: Always shake both bottles before use to ensure the heavy minerals are suspended.
2. Fill your reservoir: Start with clean water in your tank or watering can.
3. Add Part A: Pour the required amount of Cali Pro Grow A. Stir the water well.
4. Add Part B: Pour the equal amount of Cali Pro Grow B. Stir well again. Important: Never mix A and B directly together in their concentrated form; always dilute them into the water one by one.
5. Check pH: Adjust your pH to the optimal range (5.8–6.3) for best absorption.
6. Feed: Water your plants and watch them explode with growth.

Frequently Asked Questions

How much Cali Pro Grow should I use?

The dosage varies depending on the week of the vegetative stage, usually ranging between 1ml to 2.5ml per liter of water. Always consult the Emerald Harvest feeding chart for precision.

Can I use this during flowering?

No, this specific product is for the vegetative phase (growth). Once you flip to 12/12 or flowers start appearing, you should switch to Cali Pro Bloom A+B.

Is it suitable for soil and hydro?

Yes! Cali Pro Grow A+B is formulated to be compatible with all growing media, including soil, coco coir, rockwool, and hydroponic systems.

Why are there two bottles?

Separating the ingredients into Part A and Part B prevents nutrient lockout in the bottle. When mixed into your water, they combine to form a complete, plant-available diet.

Personal Experience of Pevgrow’s CEO (Alan)

I used to be lazy about 2-part nutrients, thinking "why bother mixing two bottles?" until I tried the Cali Pro line on a batch of clones that were struggling to root properly. The difference was night and day. Within a week, the stems thickened up noticeably, and the green color of the leaves became incredibly intense.

What I really like about this Emerald Harvest set is that it doesn't leave that salty sludge at the bottom of the reservoir that other brands do. It runs super clean. My tip: even if you are in soil, check your pH after mixing. This stuff is potent, and getting the pH right unlocks its full power. It’s definitely a "set it and forget it" solution for the veg stage.
