Want California-Grade Results? Start with the Full Emerald Harvest Cali Pro Line-Up.
The Emerald Harvest Cali Pro Nutrient Kit gives you the core Emerald Harvest feeding programme in one complete bundle, put together by us at One Stop Grow Shop to make running the range simple from start to finish.
Built around Cali Pro Grow A&B and Cali Pro Bloom A&B, this kit covers the full grow cycle with base nutrients, root support, plant tonic, bloom boosting and crop-quality support all included.
Choose from a 1–4 plant kit or a larger 1–8 plant kit, depending on your setup. Both versions follow Emerald Harvest’s own starter-kit structure, using the key products from the range in sizes spec’d by our team for smaller or larger grow spaces.
Pair it alongside a Basic pH & EC Testing Kit for best results, especially if you’re growing in coco or hydro.

What Each Emerald Harvest Nutrient Does
Cali Pro Grow A&B is Emerald Harvest’s vegetative base nutrient. It gives plants the core nutrition they need while building roots, leaves, stems and overall plant structure.
Use Cali Pro Grow A&B during propagation, transplanting and vegetative growth, before switching over to Cali Pro Bloom A&B when your plants move into flowering.
Cali Pro Bloom A&B is Emerald Harvest’s flowering base nutrient. It provides the core nutrition plants need during bloom, supporting flower and fruit development through the most demanding stage of the grow.
Root Wizard is a root-zone additive containing beneficial bacteria. It helps support microbial activity around the roots, giving plants a stronger foundation for healthy growth and nutrient uptake.
Emerald Goddess is a premium plant tonic used to support plant health, vigour and natural growth processes. It works alongside your base nutrients to help keep plants active and performing throughout the cycle.
King Kola is Emerald Harvest’s bloom booster. It provides phosphorus and potassium support during flowering, helping plants through the bloom stage when nutrient demand increases.
Honey Chome is an aroma, flavour and carbohydrate additive. It helps support the plant’s natural qualities while also feeding beneficial microbes in the root zone.

Why Cal-Mag and Sturdy Stalk Aren’t Included
Cal-Mag and Sturdy Stalk can be useful in certain situations, but they are not always needed by every grower. Your water type, growing medium, system and plant response all make a difference.
For most growers, it makes more sense to start with the main Emerald Harvest kit, then add Cal-Mag or Sturdy Stalk separately if your setup actually needs it.
This Kit Is Ideal For:
- New growers who want a complete Emerald Harvest nutrient programme that is easy to follow
- Growers switching to Emerald Harvest and wanting the main Cali Pro range in one bundle
- Soil, coco and hydro growers looking for a full-cycle feeding kit
- 1–4 plant setups using the smaller kit
- 1–8 plant setups using the larger kit
- Growers using full grow tent kits who want a matching nutrient bundle
- Anyone wanting better value than buying the bottles individually
How Long Will It Last?
The 1–4 plant kit is designed for smaller grow spaces and lower plant counts, giving you the main Emerald Harvest bottles in 0.95L sizes.
The 1–8 plant kit steps up the flowering-stage support properly, with larger Cali Pro Bloom bottles and 3.79L bottles of Emerald Goddess, King Kola and Honey Chome. That gives larger setups more headroom through the most demanding part of the grow.
How long each kit lasts will depend on plant size, veg length, growing medium, system type, feed strength and how often you water.
How to Use Emerald Harvest Cali Pro
Always add nutrients to fresh water one at a time and mix well between each product. Do not mix concentrated nutrients together undiluted.
Use Cali Pro Grow A&B during vegetative growth, then switch to Cali Pro Bloom A&B during flowering.
Add Part A to your water first, mix well, then add Part B and mix again. Add boosters and additives separately, mixing between each product.
After mixing your nutrients, check your pH and EC before feeding. Emerald Harvest recommends an ideal pH range of 5.8–6.3 after mixing nutrients, with an ideal water temperature of 16–22°C.

*Feed rates are based on Emerald Harvest’s official 2-Part Nutrient Series feed chart. Cali Pro A&B are used in equal parts. To extend the vegetative phase, repeat one or more late veg weeks. To extend the flowering phase, repeat one or more mid-flowering weeks. Always monitor plant response and adjust feed strength if needed.
Need Help Feeding?
Emerald Harvest is simple once you understand the structure: Cali Pro Grow A&B for veg, Cali Pro Bloom A&B for flower, then Root Wizard, Emerald Goddess, King Kola and Honey Chome to support the full run.
If you’re growing in coco or hydro, use a Basic pH & EC Testing Kit so you can check your feed strength and pH before feeding.
If you need help choosing between the 1–4 plant kit and the 1–8 plant kit, speak to the team and we’ll help you get the right Emerald Harvest setup.
Top Tip: Keep it simple on your first run. Start at the lower end of the feed chart, watch how your plants respond, and only increase strength when they are actively growing and asking for more.
