How Cali Pro Grow A&B Works

Cali Pro Grow A&B comes with a profile of macro nutrients that will bring the very best out of your plants during the vegetative stages, featuring increased levels of nitrogen to accelerates the growth of new leaves and branches. These base nutrients use only high-grade chelated minerals, which form complexes that are more readily absorbed by the roots, ensuring that they get used more effectively. Because chelated nutrients are more available, they get absorbed at wider pH ranges than typical mineral nutrients, allowing your pH levels to fluctuate further than usual without leading to deficiencies. This makes it an excellent base nutrient for both experts and beginners; so it comes as little surprise that there are armies of satisfied customers out there who can attest to Cali Pro's effectiveness.

How to Use Cali Pro Grow A&B

Use Cali Pro Grow during the vegetative stages and switch to Cali Pro Grow when transitioning to the flowering stages, after flipping your plants to a '12 hours on / 12 hours off' cycle. Emerald Harvest actually recommend swapping to Cali Pro Grow in the second week of flower. Add Cali Pro Grow a rate of 0.5ml - 1.3ml per litre of nutrient solution. A copy of the Emerald Harvest feed chart can be found by clicking the link below this description.

Both parts of a 2-part nutrient are designed to be used together in equal amounts. Using only part A or part B, or using them in unequal amounts will result in a nutrient solution which is not properly balanced. This will almost certainly lead to your plants suffering from deficiencies.

As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.

Cali Pro Grow A&B is highly effective in any growing medium or system. The ideal pH range after mixing nutrients is 5.8 to 6.3. Keep water temperatures between 18° and 21°, using a chiller, if necessary.
