About Green House Feeding

Green House Feeding has the objective to provide cultivators globally with the highest quality plant nutrients enabling them to achieve unprecedented results by allowing plants to develop to their full genetic potential.

Not only creating highly efficient products but also simplifying the application of nutrients. Our mineral products are created in powder form which ensures they are easier to use, store, transport and have a longer shelf life than liquid plant nutrients.

The main ingredients used to formulate our nutrients are sourced in Germany and Switzerland. These countries have some of the highest quality standards worldwide.

Our products do not contain PGR’s, impurities and have the lowest possible concentrations of heavy metals.

Using only the highest quality minerals allows us to provide the purest, most efficient, highly concentrated nutrients in powder form while be ing able to guarantee 100% solubility.

Our mineral plant nutrients retain their EC & pH-value for at least one week after mixing. Highly concentrated stock solutions can even be kept for several months.

All our products are in compliance with CE regulations 889/2008 and 2003/2003.

Resources

Soil - Mineral Nutrient Schedules

  • The values in the following tables are calculated using water with EC 0.0
  • Hanna TDS (500ppm = 1.0 mS/cm)
  • The pH value may decrease depending on water quality and temperatures
  • When adding Calcium the PH values may increase depending on water quality and temperatures
  • Do not use CalMag with our mineral line. Calcium Nitrate is partly incompatible with Monopotassium Phosphate and Magnesium Sulfate and may result in formation of gypsum, clogging pipes or creating deficiencies
  • Our mineral plant nutrients do not contain calcium, which means that if you use very soft water, rainwater or osmotic water, calcium needs to be added
  • Keep the nutrient solution between 65 – 72 degrees F
  • Control the EC of the runoff and flush if it’s higher than EC 2.5 (1250ppm)
  • For best results maintain a pH value between:
    • Soil: 6.0 – 6.5
    • Hydro/Coco: 5.8 – 6.2
    • Rockwool: 5.5 – 6.0

Bio Organic Nutrients Schedule

BioGrow & BioBloom Information
 
  • BioGrow and BioBloom need to be mixed into the substrate or applied as top dressing.
  • It can be used in soil, coco or similar substrates.
  • The nutrients will be released constantly during a period of 8 weeks.
 

BioGrow Dosage for Vegetative Growth:

Mother plants:
 
  • 12 – 18g/Gal substrate
  • 8 – 12g/Gal substrate every two months (as top dressing)
 
General guidelines for BioGrow:
 
  • If the growth period is less than 8 weeks or the substrate is pre-fertilized, doses should be decreased.
  • Use half dosage for seedlings and young plants (2 – 3 weeks old).
  • If the growth period is longer, a second application is required (as top dressing).
 

BioBloom Dosage for Flowering:

8 weeks flowering period:
 
  • 1st week = 12 – 18g/Gal substrate
 
10 weeks flowering period:
 
  • 1st week = 8 – 12g/Gal substrate
  • 3rd week = 4 – 5g/Gal substrate
 
12 weeks flowering period:
 
  • 1st week = 12 – 18g/Gal substrate
  • 5th week = 4 – 5g/Gal substrate
 
Dosage recommendations can be decreased for light feeder plants and pre-fertilized soil or increased for heavy feeders.
 

BioEnhancer Dosage:

  • Mix BioEnhancer with water and apply to the plants when watering, once every two weeks.
  • Can be used during the whole cycle (vegetative growth and flowering).
  • Use the Enhancer after transplant for better root development.
  • Use within 24 hours after mixing!
 
BioEnhancer Dosage:
 
  • Adding the Enhancer to water will increase the pH-value to around 8.5.
  • When using as foliar spray or as a drench on soil it is not necessary to adjust the pH down.
  • When using as a drench for coco, we recommend to adjust the pH before adding Enhancer to 5.0.
 
Media Drench:
 
  • 2 – 4g per US Gallon water every two weeks.
 
Rooting cuttings:
 
  • Soak/drench the medium with 1 – 3g per US Gallon water before placing the cutting.
 
Germinating seeds:
 
  • Soak the seeds in a solution with 2 – 3g per US Gallon water for 8 – 12 hours.
 
Foliar application:
 
  • Mix 3 – 5g with 2.5 US Gallon water and apply once every two weeks during vegetative stage.
  • For mother plants, apply 24 hours before taking new cuttings.
