Green House Feeding, powdered fertilizers

Green House Feeding Long Flowering is a water-soluble mineral fertilizer powder with NPK 18:12:18. The formula is designed for plants with a flowering period of more than 10 weeks.

When should you choose Long Flowering?

Flowering duration is a key factor when comparing it with Short Flowering and Hybrids. These are different base formulas, so choose the one that suits your crop and feeding program.

Preparing the nutrient solution

Weigh the dose according to the schedule for the specific substrate and dissolve it in water. Measure EC and pH, taking into account the source water and other products. One concentration is not suitable for every growth stage and condition.

Do you need a booster?

Booster PK+ is a flowering supplement used according to the relevant schedule. When adding a booster, adjust the base fertilizer dose as needed.

Green House Feeding Grow, also known as Powder Feeding Grow, is a powdered mineral fertilizer for the vegetative phase. The formula is intended for actively growing plants, including mother plants and cuttings.

How is it applied?

Dissolve it in the watering water. Choose the dosage according to the plants’ age, the substrate, and the water quality. For pre-fertilized soil, the manufacturer recommends starting after 2 to 4 weeks with a mild solution of 0.5 g/L. This is a specific scenario, not a universal dose.

Grow or BioGrow?

Grow dissolves in water. BioGrow is a separate organic fertilizer that is mixed into the substrate. The two products have different application methods.

Transition to flowering

Compare Short Flowering, Hybrids, and Long Flowering according to the crop. Follow the label on the package you have and the appropriate schedule.

Green House Feeding BioEnhancer is a powdered additive containing humic acids, seaweed extract, Trichoderma harzianum, and Bacillus subtilis. It is used as a soil conditioner and to support nutrient uptake.

Dosage and frequency

When watering: 0.5 to 1 g per liter of water, once every two weeks, during growth and flowering. For foliar application, the manufacturer specifies 3 to 5 g per 10 liters of water. Use the prepared solution within 24 hours.

Important for coco

For coco substrate, adjust the water pH to 5.0 before adding BioEnhancer. This instruction applies to preparing water for this product, not to a universal target for the final nutrient solution.

How does it fit into the Bio program?

Compare it with BioGrow for growth and BioBloom for flowering. BioEnhancer serves a complementary function.

Green House Feeding Booster PK+ is a powdered mineral flowering supplement with NPK 0:30:27, magnesium and trace elements. It supplements the main nutrient solution with phosphorus and potassium.

Booster or base fertilizer?

Booster PK+ is used alongside a chosen base formula, such as Short Flowering, Hybrids or Long Flowering. Using it on its own does not constitute a complete feeding program.

How do you determine the dosage?

Follow the schedule for the specific substrate and growth stage. Adjust the base fertilizer dosage to account for the added booster. Dissolve the measured amount in water and check the total EC, rather than adding the booster to a solution that is already at maximum concentration.

Combining with other products

Avoid doubling up with other PK boosters unless your feeding program has been specifically adjusted to account for them. For guidance, see the Green House Feeding mineral fertilizers and supplements.

Green House Feeding Hybrids is a water-soluble mineral fertilizer powder with NPK 15:7:22. The manufacturer recommends it for hybrid varieties with a flowering period of around 8 to 10 weeks and for hydroponic growing.

Which systems is it suitable for?

It can be used in a feeding program for soil, coco, rockwool, and other hydroponic systems. The formula contains magnesium and does not use urea as a nitrogen source.

Application and monitoring

Weigh the required amount, dissolve it in water, and follow the schedule for your chosen substrate. In coco and hydroponics, measure pH and EC. With soft water, assess the need for CalMag based on the complete solution.

Choosing between formulas

Compare it with Short Flowering for a shorter flowering period and Long Flowering for a longer flowering period. Booster PK+ is added separately according to the schedule.

Green House Feeding Short Flowering is a powdered mineral fertilizer with NPK 16:6:26. It is designed for plants with a short flowering period of around 8 weeks or less.

How does it differ from the other formulas?

Short Flowering is a base nutrient formula tailored to a short flowering cycle. Hybrids and Long Flowering are alternative formulas with different nutrient profiles. Choose according to the specific needs of the crop.

Preparation and dosage

Dissolve the weighed dose in irrigation water and follow the appropriate feeding schedule. Account for any pre-fertilization of the substrate, the source water's EC, and all additives. Do not apply one maximum dose throughout the entire cycle.

Adding to your feeding program

Booster PK+ is a flowering additive whose use should be coordinated with the dose of the base fertilizer. For the mineral range, see all Green House Feeding mineral products.

Green House Feeding Calcium is an EDTA-chelated calcium supplement. It is intended to make up for insufficient calcium in the water and substrate.

When is it needed?

Assess this based on water quality and the base nutrient program. With hard water or calcium-rich soil, the manufacturer recommends not adding Calcium.

Dosage

The recommended range is 0.5 to 1 g per liter of water, with the amount reduced according to the calcium already present. This is a guideline for when a need has been established, not a mandatory additive for every watering.

Calcium or CalMag?

Green House Feeding recommends Calcium for soil growing with peat-based mixes, and CalMag for coco, rockwool, and hydroponics. CalMag also supplies magnesium and nitrogen, so the two products are not interchangeable at the same dose. Do not combine them as two calcium supplements.

Green House Feeding BioGrow is a dry organic fertilizer with NPK 7:2:4 for the vegetative phase. It contains natural raw materials and gradually releases nutrients over a period of around 8 weeks.

Application to the substrate

Mix it into the substrate when planting or work it into the top layer. The manufacturer recommends 3 to 5 g per liter of substrate. Reduce the dose for young plants, shorter growth periods, or pre-fertilized mixes. It is suitable for soil, coco, and similar substrates as part of the Bio program.

Calculation example

At a chosen rate of 3 g/L, a 10-liter pot requires 30 g of product. This is a calculation based on substrate volume, not a dose for irrigation water.

BioGrow or mineral Grow?

Grow is a water-soluble mineral product. For the organic program, compare BioBloom for flowering and BioEnhancer.

Green House Feeding CalMag is a water-soluble mineral supplement containing calcium, magnesium and nitrogen. It is used to supplement according to water quality and the nutrient program.

Dosage and soft water

The official range is 0.1 to 0.5 g per liter of water. For reverse osmosis or rainwater, the manufacturer recommends 0.5 g/L. Use an EC meter and account for the base fertilizer. With hard water, adding it is not automatically necessary.

Which systems?

CalMag can be used in hydroponic and coco programs and in fertigation. It differs from Calcium, which is a separate chelated calcium supplement. Do not mix CalMag with another calcium supplement.

Composition and compatibility

The declared values are 13.5% N, 16.7% CaO and 6% MgO. CaO and MgO are oxide designations, not percentages of elemental calcium and magnesium. See Green House Feeding mineral fertilizers for base nutrients.
