How Humboldt Nutrients - Master A&B works:

Humboldt Nutrients - Master A&B is a technologically advanced 2-part base nutrient. The latest in scientific research by Humboldt Nutrients has produced a plant-food where all the vital elements are wrapped up in their own amino chelated molecules. This makes the food very stable and much more available to your plants over a wider pH range. As a result, your plants get what they want, when they want it, in a form that they can absorb in a natural way!

Master Part A provides nitrogen, potassium, calcium and micro-nutrients, while Master Part B provides phosphorous, potassium and magnesium. Because of the great availability of the all the nutrients, Master A&B can be used perfectly with almost any grow-medium, whether it's soil, coco, rockwool or clay pebbles. And it works in almost any type of feed-system - hand-watering, drain-to-waste or recirculating hydroponics.

Humboldt Nutrients - Master A&B is for almost any type of grow-medium - soil, coco, rockwool, clay pebbles etc. and for almost any type of system - hand-watering, drain-to-waste or recirculating hydroponics.

The water that you begin with can have a large impact on your results. Humboldt nutrients recommend un-chlorinated water which is oxygenated before and during use. To achieve this, Humboldt Nutrients themselves use Reverse Osmosis water which has been "bubbled" well with an airpump and airstone before use and while it is in the reservoir.

Always shake the bottles well before use. For best results, please refer to Humboldt Nutrients own feeding chart. In general, equal amounts of Master Part A and Master Part B are used right the way through your grow in both veg and flowering. Expert growers may wish to experiment with the ratios using more Part A than B for veg and vice-versa for flowering. Also, exact amounts to add will vary depending on which boosters you will be using with it. As a guideline, use between 0.26 - 1.82 ml/litre of each in veg and between 1.04 - 2.08 ml/litre of each in flowering. After this, add any boosters or additives that you wish to use. Finally, check and adjust the pH as necessary.

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.

Manufacturer's recommended dosage rates are only for vigorously growing plants that are in the peak of health. Slower growing plants and those that are not 100% healthy will require a lower dosage rate.

Always ensure that when hand-watering in soil, you wet the soil thoroughly and achieve 10% – 20% run-off each time.
