Why You Need It

Your base nutrient does most of the heavy lifting in any feeding programme. If the core feed is off, everything else is just patching holes.

Cali Pro is designed to give plants the key elements they need at each stage without overcomplicating the process. The Grow formula supports strong vegetative development, while the Bloom formula shifts the balance toward flowering performance.

It also includes secondary nutrients and chelated micronutrients such as iron, copper, manganese and zinc, which Emerald Harvest highlights as part of the formula for healthy growth, chlorophyll production and efficient plant function.

How to Use

Use Grow A + Grow B during propagation, transplanting and veg. Once you flip into flower, switch over to Bloom A + Bloom B.

Always use equal parts of A and B. Never mix the concentrates together undiluted. Add Part A to fresh water first, mix well, then add Part B. Emerald Harvest’s official feed guidance also recommends an ideal nutrient solution pH of 5.8 - 6.3 and water temperature of 16 - 22°C.

Caution: Do not aerate or use in bubbler systems.

Top Tip

If you want a quick rule to remember, Cali Pro is always equal parts A and B – just change from Grow to Bloom when you switch into flower. That makes it a great choice if you want a proper base nutrient without a complicated feeding routine.
