How do I use Green House Feeding?

There are two different ways to use Green House Feeding.
 

The easiest way is for those new to growing and who do not measure their PH and EC values. The second is for experienced growers who prefer to monitor their plants and feeding accurately.

Important: This schedule should only be used when growing in soil, using water with Calcium in it.

Beginner / easy growers:

If you grow on pre-fertilized soil we recommend starting using Green House Powder Feeding 2-4 weeks after planting the seeds and to start with a mild solution (0.25g per Liter). During the vegetative stage you can increase the feeding up to 0.7g per Liter.

With the beginning of the flowering stage you should slowly increase the amount of Powder Feeding until you reach 1g per Liter.

Following this schedule, there should usually be no problem and growers can achieve a decent yield.

In order to achieve the best possible results we recommend measuring pH and EC value of the feeding solution.

 

Needed items:

 

Scale                    Container            Water                   PH +/-

      

    

Experienced growers:

Experienced growers usually measure their feeding solution to provide the plants with the exact amount of nutrients and the correct pH value of the solution. Whether you grow in coco, hydroponics or aeroponics – with all of these systems you should measure your pH and EC values.

When using a pH and EC meter you can optimize your growing and achieve much better results.

Steps to take when mixing nutrient solution:
 

  1. a) Check pH and EC value of the water and make sure the temperature is about 18-22 degrees Celsius. You should also check if your water contains enough Calcium.

  2. b) If your EC is 0,0 (using RO or rain water) you need to add Calcium to your water before adding Powder Feeding. Make sure your EC rises up to 0.3-0.4 EC

  3. Add Powder Feeding and mix well for 2-3 minutes, and then measure the EC value. If necessary repeat until you reach the desired value.

  4. When you reached the desired EC value, wait for 15-30 minutes.

  5. Then measure the pH and if necessary adjust it using pH up or pH down.

  6. When you reached the desired values, feed your plants.

 

Needed items:

 

PH & EC Meter    Container             Water                    PH +/-                                    (Calcium)           

          (if necessary)   

 

Can Green House Feeding be used on Every medium?

Green House Feeding can be used on every medium. However the feeding schedule is slightly different and if using anything than soil we recommend using a PH- and EC-meter in order to achieve the desired values and have full control over your feeding solution.

 

Soil


Soil or soil-based mediums are the most commonly used form of growing medium, mainly because they are available in most areas, cheap and easy to maintain.

Most beginner growers use soil mixes because soil also works as a buffer for pH-fluctuation and nutrient deficiencies.
There are different ready-to-use soil-mixes from different companies, as well as DIY soil-mixes where one can find many recipes on the Internet.

Most soil-mixes are pre-fertilized for the first 3-8 weeks. If the soil is heavily pre-fertilized the grower needs to be careful with seedlings and young plants. The grower does not have very much control over his feeding regime in that case. We recommend using only light fertilized soil, which contains enough nutrients for the first 3-4 weeks of the plants life.

Green House Feeding will work perfectly in soil. When growing in soil, we recommend feeding the plants only every other watering (water – nutrient solution – water – nutrient solution) to avoid salt build up in the medium. We also recommend flushing the medium 2-3 times with pH-balanced water during the whole cycle depending on the flowering time.

Due to the high quality of the mineral salts we use, the plant can assimilate the nutrients easily and salt build up will be minimal. When flushing regularly, there won’t be any excess salts left in the medium.

In the last 7-10 days of the flowering period we recommend to flush the medium only with pH-balanced water.

Coco                    Hydro                 Aero

    

Hydroponic growing is becoming more popular as it’s seen as people have more control over the feeding regime. The definition of hydroponics means ‘water-working’. This means as much as growing plants in a water and nutrient solution, without soil. Growing with a hydro-setup is usually more efficient and productive compared to soil setups. However it requires more attention of the grower, as he needs to monitor his pH and EC value closely.

In hydroponics you provide the exact nutrients your plants need. There are different hydroponic setups such as Deep Water Culture (DWC), Nutrient Film Technique (NFT), Ebb and Flow, Drip Systems and Aeroponic Systems.

Also growing in coco is a hydroponic method where the coco fiber is used in the same way one would use soil. However the feeding needs to be more controlled compared to soil, as coco is not working as a buffer.

Green House Feeding will work perfectly in coco and hydro setups.

Normally you will not have to use any other nutrients except the Powder Feeding.

Only in case you use RO water or rain water (with an EC of 0.0) we recommend adding our Additive: Calcium in order to raise the Calcium level to the desired value.

Normally you can keep your feeding solution in a light proof reservoir up to 10 days, however we recommend changing the solution weekly.

Can Green House Powder Feeding be used for foliar feeding?

Green House Powder Feeding Grow can be used for foliar feeding.

 

Foliar fertilization is a highly effective way for quick nutrient uptake. By spraying the leaves, the plant can take up the nutrients quickly and the effects can be visible even within hours.

When mixing your solution for foliar feeding take 100ml of your regular feeding solution (e.g. 1g per 1 Liter) and mix those with 900ml water.


Our Additive: Calcium can also be used for foliar application to achieve fast results and strengthen the cells. We recommend using 0.5g per Liter in a foliar feeding solution.


Foliar fertilization should be done after your regular watering (pH and EC-values according to your feeding schedule) at low light intensity to avoid light burns.


For fast nutrient intake, the pH value for foliar feeding should be between 5.5-6.5

Is Green House Powder Feeding organic?

Our Green House Powder Feeding is a mix of high quality minerals in the correct composition for your plants. Minerals do not contain any living material and as such cannot be called organic. However that does not mean that the minerals are chemically produced.

 

There are two production methods for mineral fertilizers: Chemical synthesis and derived from rocks. Green House Powder Feeding is a combination of those two. All metal micronutrients are chelated with EDTA which is considered organic by the Fertilizer European Regulation EC 2003/2003 in Annex I section E. 3 page 50.

Can Green House Powder Feeding be used in combination with Dosatron®?

Green House Powder Feeding can be used with a Dosatron® system.

 

The recommended dosage for Dosatron® is 30g/L

 

The saturation point of Green House Powder Feeding at room temperature is 160g/L

Does Green House Green House Powder Feeding contain any harmful materials?

In terms of leaving residues in the medium, Green House Powder Feeding is a very clean product.

 

Urea:


Green House Powder Feeding does not contain urea.


Although urea is the easiest and cheapest way to deliver nitrogen to the plant we decided not to use urea as a source of nitrogen but other salts of higher quality, which do not leave residues such as Biuret in the medium.


Biuret is the result of condensation of two molecules of urea and is a problematic impurity in urea-based fertilizers. A build up of biuret in the medium increases the risk of ammonia toxicity.

 

Heavy metals:


Green House Powder Feeding does not contain heavy metals that can be considered harmful for humans, animals or plants.

Chlorine:


Green House Powder Feeding does not contain Chlorine, which may kill beneficial bacteria in the medium.

Fluorine:


Green House Powder Feeding does not contain Fluorine, which is potentially toxic for the plants.

Does Green House Powder Feeding contain Sulfur?

Green House Powder Feeding contains a small amount of Sulfur and it is enough for the plant but is not obligatory to declare it on the label. Every country has different laws with the packaging label but most of them don't include the Sulfur as obligatory nutrient to specify on the label.

Green House Powder Feeding contains MgSO4 (magnesium sulfate) and other salts with a perfect ratio of sulfur.

Do I need to add other nutrients?

Our Green House Powder Feeding really is an All-In-One feeding solution, which includes all necessary macro- and micronutrients for the full growth cycle of your plants, and no other nutrients are necessary. Due to the powder form, all macro- and micro-nutrients can be combined in one product and don't need to be separated until use like most liquid products.

 

Only in case you use RO water or rain water (with an EC of 0.0) we recommend adding our Additive: Calcium in order to raise the Calcium level to the desired value.

When do I need to use Additive: Calcium?

Additive: Calcium

Calcium (Ca): 9% (chelated Calcium)

 

Calcium is essential for growing a healthy crop. It prevents and corrects deficiencies, which are caused due to lack of/or imbalance in the assimilation of Calcium.

 

Our Green House Additive Feeding CALCIUM is very soluble, easy to use and quickly assimilated.

 

  • Very soluble, easy to use, quickly assimilated
  • Chelated Calcium – EDTA is a stable product that does not interact with other elements.
  • Strengthens cell membrane and cell walls to protect from pests and insect attacks.
  • Presented in a powder form, it is very soluble in water.
  • Ca2+ ion is protected by EDTA
  • Minimum effort and very easy to use
  • Enhances nutrient transportation
  • Accelerates cell division and root extension
  • It does not contain Chlorine
  • It’s compatible with all kinds of fertilizers
  • It is perfect to solve a lack of Calcium

 

 

How to use:

 

Mixing: When added to water make sure to start mixing immediately.

 

RO, Rainwater or any water with EC 0.0:

 

Because these kinds of water don’t have the necessary amount of either Calcium or Magnesium,

it is necessary to use Calcium additive when used with any Green House Powder Feeding products.

 

For your convenience Magnesium is included in Green House Powder Feeding

 

Also remember that most tap water already has enough Calcium.

Can I add other products like Mycorrhizae, Trichoderma or Enzymes?

Yes, all those additives can be used in combination with Green House Feeding.


Mycorrhizae and Trichoderma increases the nutrient uptake and make the nutrients better available for the plants whilst Trichoderma protects the plant from harmful root fungus.

What is the pH Value?

The PH value shows the acidity or the alkalinity of water. (pH stands for the potential hydrogen ions in the water). The easiest and most accurate method to get a precise measurement is an electronic PH meter.

Throughout the scale of 1-14 (1 being very acidic and 14 being very alkaline) the absorption by the plant will be affected differently with the required nutrients.

 

Therefore we advise constant monitoring of pH levels in order to prevent damage to the root system and the plant. 

 
 

Specific nutrients are better absorbed at different pH levels as shown in the graphic above. 

What is the EC / PPM value?

The amount of ionic salts in water is measured by two scales, electrical conductivity (EC) and parts per million (ppm). The more ions are dissolved in the water the better it is at conducting electricity. With the EC & PPM we measure the amount of nutrients (salts) that are present in the water (feeding solution).

It is impossible to create one feeding schedule for all plants, as every plant is different and just like humans; the plants diets vary from lighter to heavier meals. The optimum EC value changes with different plants and foods.

Tap water usually has an EC value between 0,3 EC (=192 ppm) and 1,1 EC (=704 ppm). However it varies in different countries and areas.

In our feeding schedule you will always find the final EC value, which means the initial EC value of the water needs be taken into consideration.

Example:

Tap water EC: 0.7 (Amsterdam)

Desired EC value week 5 Hybrids: 1.6

We need to add the right amount of Green House Powder Feeding (0.9 points) to achieve the final EC value of 1.6

Important! If you need to adjust the pH value of your water (using pH+/-) you should always mix your nutrients solution first. When you reached the desired EC value you can add the pH regulating product.

Which Green House Bio Feeding do I need?

In our Bio line, we have only one product for each stage of the plants lifecycle. Both products can be used for most plants.
BioGrow is used during the vegetative stage of the plants lifecycle, while BioBloom is used for the flowering period. Both products are slowly releasing nutrients over a period of eight (8) weeks. If the specific stage is longer than eight weeks, a second application is required.

Is an Green House Bio Feeding be used for foliar feeding?

Since our products BioGrow and BioBloom are slow release nutrients made from organic raw materials, they are not water soluble and can only be applied to the soil / coco directly.
Our BioEnhancer on the other side is water-soluble and can be used for foliar feeding as well as a soil drench.
Foliar spray:
Mix 3 - 5g with 10L Water and apply once every two weeks during vegetative stage.
Very effective for mother plants, apply 1-2 days before taking new cuttings.


Is Green House Bio Feeding organic?

Our Green House Bio Feeding is derived from organic and mineral raw materials.
All three products are certified for organic agriculture by Control Union (Input: Organic EU).

CONTROL UNION CERTIFIED EU

Control Union is an international organisation for organic production inspection and certification.
The certification is in accordance with standard ECC Regulation No. 271/2010. This organisation guarantees that certified products do not contain any chemical fertiliser or pesticide, chemical or synthetic flavours, colours or preservatives, or genetically modified organisms (GMO).

OMRI supports organic integrity by developing clear information and guidance about materials, so that producers know which products are appropriate for organic operations. OMRI is a nonprofit organisation that provides an independent review of products, such as fertilisers, pest controls, livestock health care products, and numerous other inputs that are intended for use in certified organic production and processing.

Currently we are also working on organic certifications in other countries.


Can Green House Bio Feeding be used in combination with automatic watering systems?

Our two nutrients BioGrow and BioBloom are applied to the soil so there is no dosing system necessary to provide the nutrients. Only plain water is necessary – The big advantage with automatic watering systems is, that no nutrients need to be mixed in the reservoir and with plain water there is no risk of clogging which is very common with organic liquid nutrients.


Does Green House Green House Bio Feeding contain any harmful materials?

Our Bio Feeding line does not contain any harmful materials.


Do I need to add other nutrients?

Our Green House Bio Feeding really is an All-In-One feeding solution, which includes all necessary macro- and micronutrients for the full lifecycle of your plants, and no other nutrients are necessary.


Can I add other products like Mycorrhizae, Trichoderma or Enzymes?

BioGrow and BioBloom both contain large amounts of microbial life, such as mycorrhizae. These microbes are not added to the products but occur naturally in the raw ingredients. Due to the fact that it is very inefficient to test the exact species and amounts of microbes in the product, we do not claim the contains on the label.
Our BioEnhancer does contain inoculated species of Trichoderma and Bacillus Amyloliquefaciens.
Organic additives (e.g. Enzymes and other microbial products) can be added to the feeding program when using Green House Bio Feeding but are not necessary to achieve good results.


Can BioFeeding be used in hydroponics?

Green House Bio Feeding can only be used in soil or coco, it needs to be mixed into the substrate.


Does the pH-value of the water need to be adjusted?

We advise you to adjust the pH value of your water with organic methods if it's required. On soil the value should be between 6.0-7.0 and on coco between 5.8-6.5


Can the Enhancer be used with mineral feeding?

The Enhancer can be used in combination with mineral feeding, but the microbial live might be affected by the minerals and the desired effect might not be the same.


Which dosage can be used per square meter?

We recommend for both products, BioGrow and BioBloom a dosage of 120-200g/square meter.


What is the fungus / mould on the soil after using BioFeeding?

Mycelium from beneficial fungus can appear on top of the substrate.It improves microbial life inside the substrate and will not harm humans, animals or plants.Fungi is the main agent of the decomposition of organic matter such as simple sugars, amino acids, etc.It solubilizes minerals that are not initially available to plants.


Do I need to add extra sugars like molasses when using BioGrow/BioBloom?

Our BioGrow and BioBloom contain vinasses which is a form of sugar so it is not necessary to add more sugars.
