Green House Feeding

Green House Feeding

Green House Feeding is a award winning nutrients brand. The fertiliser range is developed to target different types of plants in different growth stages.

Commonly asked questions:

How do I use it?

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.

    1. 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

    1. 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.

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

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

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

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 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.
