1. What is a fertilizer, and what is a stimulator??

A basic fertilizer always contains certain amounts of all 3 basic nutrients. These are nitrogen, phosphorus and potassium (N-P-K), and they are usually printed on the product label in this order.

In contrast, stimulatory agents contain all other substances which do not have a significant N-P-K value. This can be recognized by missing or only small N-P-K values, for example 1-0-0, 0-1-0 or 0-0-1. We declare our products clearly in the appropriate area of application, with plant aids, soil improvers, stimulators and basic fertilizers.

Soil improvers, plant aids and stimulators can therefore be applied with every watering in their respective phase.

2. Why should you use fertilizers??

For an optimal, healthy plant growth and lush yields without nutrient deficiencies, the constant availability of all required nutrients is necessary at all times. Since the plants’ nutrient requirements vary, we have adapted our products specifically to these individual needs with three different N-P-K fertilizers for an adequate supply of all nutrients without the occurrence of undesirable deficiencies.

3. How often should the basic fertilizer be used??

Many factors depend on this. However, as soon as the first deficiencies develop and become visible on the plants, you can assume that it is either time to repot, fertilize more regularly, or start fertilizing with a higher dosage. A healthy leaf color shows that the plant is healthy and vital. If that is the case, the plant currently has optimal conditions, and you should wait with the fertilizing until the next watering. A too-dark foliage color indicates that there are currently too many nutrients in the plant substrate. In that case, the usual quantity of fertilizer should at least be halved or, better yet, suspended.

When growing in soil, we recommend applying the basic nutrients every other time the plants are watered. During the last weeks of heavy flowering, plants may require a dose of fertilizer with every watering, depending on the strain.

For all other growing substrates, we recommend a regular application of N-P-K fertilizer.

4. In which growing media can the products be applied??

All Green Buzz Liquids products can be used with any growing media. This includes soil, coco, expanded clay, rockwool, perlite, flood tables, NFT-systems, and airpot systems. All products can be applied via capillary hose as small as 1mm inside diameter without concern. When used in the nutrient tank, care must be taken to ensure a constant circulation of the nutrient solution with the help of a circulation pump or a biofilter and the application of Trichoderma and bacterial fungus strains, such as our product Living Organics.

5. Why are some bottles/cans pushed in??

A rapid temperature change can lead to a slight denting of the bottles canister after the filling process.

This impression does not constitute a quality defect.

In addition, less oxygen in the container reduces the oxidation.

6. Why do some products smell unpleasant??

Because of the effective microorganisms within Humic Acid Plus, the products tend to produce an unpleasant odor, much like rotten eggs, after opening. This is no reason to be concerned; on the contrary, it shows the product is full of life. Millions of microorganisms are feeding on humic substances, processing them to enzymes, which in turn are responsible for the unpleasant smell.

7. How often should plants be sprayed with Fast Plants Spray or Fast Buds??

As a general rule: spray plants every 2-3 days, especially on the underside of the leaves. Spraying plants daily is generally possible, but only recommended over a short period of up to 7 days. An application is only recommended until a clear effect is seen in form of spurted growth, or – in the case of Fast Buds – until the first flowers appear. From then on, a further application with Fast Plants Spray is no longer necessary.

8. How long can plants be sprayed, and with what??

Plants should only be sprayed during the vegetative stage until flowers start to show.

The following products can be applied as a spraying solution: Fast Plants Spray, Humic Acid Plus, More Roots & Fast Buds. When applied over the foliage, the dosage can be raised to 10 times the concentration (10-20ml per liter) without concern.

9. When should plants be sprayed??

Just before or after the light source is extinguished, the plants are sprayed until completely dripping wet on the upper leaf surface and the undersides. If the plants are protected from excessive light after spraying, they can be sprayed at any time.

10. Can the plants be watered / sprayed daily with Fast Buds??

Yes, the more often plants are treated with it, the faster they start with the actual fruit setting.

11. What is the ideal temperature for the nutrient solution??

Plants thrive best when they are supplied with water at constant temperatures of around 21-23° C.

It is advisable to allow water to stand for at least 24 hours before each use, since there can be chlorine present in the tap water, which needs time to escape completely.

12. What is a breeding plan/growing shedule??

A breeding plan is a standardized guide and a recommended method of dosing our products. The information is based on experience and may need adjustment depending on the individual requirements of the strain and phenotype grown.

13. What is the ideal pH-value for my nutrient solution??

When growing in soil or any other growing media we recommend a pH-value of 5.8 – 6.5. For hydroponics it should be kept a bit lower at 5.5 – 6.2. This will guarantee that all nutrients are available to the plants and will prevent deficiencies and disease.

14. What is the EC-level and when is it at an optimum??

The EC-level tells us how many dissolved salts our nutrient solution holds. There is no ideal EC-level, because every plant has individual needs and every growth has different conditions.

The ideal EC-value for young plants with little to no roots lies between 0.6 – 0.8 EC.

During vegetative growth, the EC-level should be raised steadily from 0.8 – 1.6 EC for full growth.

When fructification begins, the EC-level should be around 1.2 – 1.8.

While flowering peaks, nutrient requirements shift and plants need more phosphorus and potassium.

The EC-level can be raised to 1.8 – 2.4 during the flowering phase.

Generally spoken, plants can take higher EC-levels if they have been accustomed to it early in life.

An EC-level above 3.0 can be toxic to plants.

Please note that only about half of the nutrient content displayed on the EC value is available.

When using organic fertilizers, please generally only use about half of the nutrient content indicated on the EC value. The values ​​of the displayed EC value can therefore also be doubled (maximum 6.0) without exceeding the current value of the plants (maximum 3.0)!

15. Do pH- and EC-levels really need to be measured??

If possible, the pH-level of the nutrient solution should always be measured and corrected before plants are watered. This will make sure all nutrients are readily available to plants.

The EC-level does not necesarily need to be measured when growing in soil. For all other growing media, we advise you to measure and correct the EC-level every 1-2 days.

16. How are pH- and EC-levels raised or lowered??

The pH-level can be lowered easily by adding some high-grade pH-Powder. The pH-Powder contains no phosphoric or nitric acids like most other pH-lowering substances that are available.

The EC-level can be raised by adding fertilizer to the nutrient solution. Lowering the EC-level is accomplished by diluting the nutrient solution with water. (Demineralized water or filtered water works best.)

17. When and how often should plants be watered??

How frequently plants should be watered depends on how much water remains in the growing media. To prevent overwatering (the most common mistake novice growers make), we recommend applying the 50% rule. Use a scale to weigh your plants after they have been watered thoroughly and write down the weight. Wait with your next watering until the plants have lost 50% of their total weight. Alternatively, you can use your finger to feel how much moisture remains in the growing media. When the media feels dry in a depth of 3-6 cm beneath the surface, it is time to water anew.

If the growing media happens to become too dry, we advise watering with only supplements only first, before applying fertilizer. It is always best to water early in the mornings, so that plants can process the water throughout the day.

18. What does “assimilation” mean??

Assimilation describes the process of converting external nutrients and microelements into a useable form that can be incorporated into the plants’ organism.

19. Why is it not advisable to administer additional enzymes mixed with other (fertilizer) products??

Enzymes convert not only dead root matter but also sugar into dextrose. In order for the plant to be able to utilize this process optimally without outside influences, we should not add any fertilizer during this time and also leave the regularly administered stimulators away, so that the plants can execute this conversion process undisturbed in the following 24 to 48 hours.

Generally, the planting substrate should be properly flushed once every 3 to 4 weeks with Clean Fruits. The pot/substrate is considered to be properly flushed when approx. 10% of the watering fluid runs out of the bottom of the medium. This regular flushing procedure is also very important for the plants in that no toxic accumulation of nutrients can develop in the substrate and no fertilizer reserves are left in the plants.

Beyond that, the fruits are much better in taste, as sugar blockages and dead root matter in the medium can be converted into dextrose more directly and in turn be absorbed and directly and effectively utilized by the plant.

20. What are microorganisms, and what do they do??

Microorganisms are the beneficial bacteria that help create elements like nitrogen and phosphorus and can be seen as the foundation of life on our planet. Beneficial microorganisms within the growing media help plants in many ways. They protect roots from fungus and heat, for example. They feed on nutrients and make them available to the plants.

21. What are microelements??

Microelements are essential elements for plants. These elements are minerals of inorganic compounds which cannot be produced by the plant itself. This is why our supplements should be given with every watering.

22. What is microflora??

The word microflora relates to microscopic life forms. Plants interact with multiple microbes that live inside or outside the plants. It is known today that plants and microflora benefit from each other and grow in symbiosis.

23. What is a chelating agent??

Chelation is a type of bonding of ions and molecules to metal ions. It involves the presence of two or more separate bonds between a multiple-bonded ligand and a single central atom. Usually, these ligands are organic compounds.

24. How is Living Organics applied???

Our Living Organics is very economical in use. Just 6.5g in a total of 4 applications is sufficient to establish all the benefits of the billions of useful, positive microorganisms and bacterial strains in the soil/medium, of which the plants contribute significantly to a successful harvest with increased vitality and nutrient conversion

The first application can be applied to the bare root of the fresh seedling, as well as to the fresh cut surfaces of cuttings plants before the actual sealing with our Fast Start Gel. The second application is usually done with the next repotting or after 2 weeks at the latest.

As soon as the plants in their vegetative phase do not get enough space in their medium it is time to repot them again.

Living Organics can be sprinkled directly on the roots while repotting (for this purpose, even minimal amounts are sufficient for and no visible expensive wetting of the entire root system, you should wet one of the 4 entire side surfaces with a knife tip, which is completely sufficient).

It is also sufficient to dissolve 1-2g/10 litres of Living Organics in a separate nutrient solution every 3 weeks at the latest and to add this to the plants.

25. When is it necessary to use our Organic CalMag??

Our Organic CalMag supplements our already successful product range to meet the requirements of newer cultivation methods as well as specially bred varieties of the American continent.

So our Organic CalMag shows its full strength especially when cultivated in airpots, on 100% coco, under LED, as well as with the now more and more present American genetics with the complete supply of these increased nutrients, especially during the flowering period. For older, already discontinued varieties and conventional cultivation methods such as soil without airpots or the use of LED as a light source, the application is however rather counterproductive, because in this case more nutrients than from the medium and the mostly less demanding genetics can quickly lead to a rather disadvantageous imbalance, if the genetics, as an exception, should not be subject to an increased nutrient requirement.
