Optimize your indoor crops with Green House Powder Feeding

When it comes to growing indoors or outdoors, one of the key elements to ensure a good harvest is feeding your plants. Green House Powder Feeding offers a range of powdered fertilizers designed to simplify this process while delivering exceptional results.

This article explores the recommended growing schedules for three types of varieties (long flowering, hybrids, and short flowering), while providing advice on fertilizer dosages and application frequency.

Why choose Green House Powder Feeding?

Green House Powder Feeding stands out for its ease of use and specific formulations for different types of plants. These fertilizers are water-soluble, allowing rapid absorption by plants and uniform feeding throughout the life cycle.

The Green House Powder Feeding powdered fertilizers from the mineral range are specially designed to provide complete and balanced nutrition to plants throughout their life cycle. Easy to use, these soluble fertilizers adapt to different types of crops, in soil, coco, or hydroponics. The Grow formula is ideal for the vegetative growth phase, promoting healthy root development and a vigorous plant. The variants Short Flowering, Long Flowering and Hybrids are optimized for flowering according to the plant's genetic type: short, long, or hybrid flowering. Each formula contains the essential macro and microelements to maximize production and improve harvest quality.

Additional precautions

• In addition to specific dosages for each substrate (soil, coco, hydroponics), here are important precautions to take to optimize the health of your plants:

  • Recommended rinsing : If the drainage EC exceeds 2.0 during flowering or 1.8 during growth, rinsing is advised.
  • Mixing the stock solution: Mix at 25°C. When adding multiple nutrients, let the solution rest for 24 hours. Stir regularly or use a circulation pump/air stone to prevent nutrient precipitation.

  These precautions help prevent salt buildup and ensure optimal nutrient absorption.

Organic Cultivation Schedule (BioGrow, BioBloom, BioEnhancer)

The organic range from Green House Powder Feeding offers a 100% organic alternative to feed your plants, thanks to the fertilizers BioGrow, BioBloom, and the additive BioEnhancer. These products can be used both in soil and coco, and gradually release nutrients over about 8 weeks. The resulting cultivation program is simple and natural, suitable for both beginner and experienced growers, while ensuring vigorous growth and abundant flowering. 🌿🌸

BioGrow 🌿 – Growth Fertilizer

BioGrow is a powdered organic fertilizer designed for the growth (vegetative) phase. Rich in nitrogen (N), it promotes the development of foliage and roots. It mixes with soil or coconut fiber and gradually releases its nutrients over several weeks. Here is how to use it effectively:

• Initial application: Mix about 3 g of BioGrow per liter of substrate (about ~30 g for a 10 L pot) when potting or repotting at the start of growth. ✅ This dose feeds the plant for about 8 weeks of vegetative growth.
• Extended growth: If the vegetative phase lasts more than 8 weeks (for example, for mother plants or long-growth varieties), apply an additional surface dose of about 2 g/L of substrate after 8 weeks to maintain nutrition. ♻️ You can repeat this application every two months for plants kept in extended growth (mother plants).
• Young plants: For seedlings, plantlets, and young cuttings (2–3 weeks old), use half a dose of BioGrow (≈1.5 g/L) to avoid overloading the substrate with nutrients. 🌱 This prevents any risk of over-fertilizing the still fragile young roots.

BioBloom 🌸 – Flowering Fertilizer

BioBloom is the organic powder fertilizer formulated for the flowering phase. Rich in phosphorus (P) and potassium (K), it supports the formation of buds and flowers. It is applied at the start of flowering and gradually releases to cover most needs until harvest. Its use depends on the flowering duration of your plants:

• Short flowering (up to 8 weeks): a single initial application of about 3 g/L of BioBloom at the switch to 12/12 (start of flowering) is enough to feed the plant throughout flowering. ✅
• Medium flowering (~10 weeks): apply 2 to 3 g/L of BioBloom at the start of flowering, then make a supplementary dose of 1 g/L around the 3^rd to 4^th week of flowering. This ensures nutritional support for varieties with slightly longer flowering. ⏳
• Long flowering (~12 weeks): apply 3 g/L of BioBloom at the beginning of flowering, then a second dose of 1 g/L around the 5^th week of flowering to support varieties with very long flowering. 🌸🌿
• Tip: No need to increase doses for low-demand plants or if your substrate is pre-fertilized – stay on the low end of the dosage range to avoid any excess. ⚠️ In case of doubt, it is better to slightly underdose (you can always add a supplement later) than to overdose from the start.

BioEnhancer 🧪 – Microbial Additive & Stimulator

BioEnhancer is an organic stimulator based on beneficial microorganisms (such as Trichoderma and Bacillus) and natural extracts (humic acids, seaweed, etc.). It improves soil life, boosts the root system, and facilitates nutrient absorption. Its use is simple and integrates into the regular watering cycle:

• Watering (any crop): Dilute 0.5 to 1 g of BioEnhancer per liter of water, then water your plants with this solution about every two weeks. 💧 Start from the beginning of the crop and continue throughout growth and flowering (for example, one application every two waterings). This stimulates the substrate microbiome and improves the overall vigor of the plants.
• After repotting: Administer a watering enriched with BioEnhancer just after each repotting or transplantation, at the dose indicated above. 🌱 This post-transplant application reduces stress and promotes a quick restart of growth thanks to better root development.
• Foliar application (during growth): It is possible to spray BioEnhancer on the foliage during the vegetative growth phase for a “boost” effect. Prepare a solution at 3–5 g per 10 L of water, then spray the underside and topside of the leaves once every two weeks. 🌿 This foliar spray strengthens plant resistance and optimizes nutrient uptake (however, avoid spraying during flowering to prevent wetting the flowers).
• Germination & cuttings: BioEnhancer can also be used to facilitate germination and rooting. For seedlings, soak your seeds in water with 0.5–1 g/L of BioEnhancer for 8 to 12 hours before sowing – this stimulates vigorous germination. For cuttings, soak the medium (peat pellet, rockwool cube, etc.) with a solution dosed at 1–3 g/L before transplanting the cutting. ✨ These practices encourage rapid and healthy rooting from the start.
• Water quality & pH: Note that BioEnhancer tends to raise the pH of the nutrient solution (up to ~8.5). For soil or foliar spray use, it is generally not necessary to adjust the pH. However, in coco substrate, it is recommended to adjust the water pH to ~5.0 before adding BioEnhancer, so that the final solution remains within a pH range suitable for coco cultivation. 🧪
• Solution preparation: Like any “living” organic product, the BioEnhancer solution must be used quickly after preparation. Mix only the necessary amount and use it within 24 hours after dilution. ⚠️ Do not store a prepared solution, as the activity of microorganisms decreases over time.

✅ In summary, this organic growing program with BioGrow, BioBloom, and BioEnhancer covers all your plants' needs from start to finish with just a few simple applications. Start with a substrate enriched with BioGrow, apply BioBloom at the right time according to your varieties' flowering duration, and don't forget to use BioEnhancer regularly to maintain a “living” soil. This way, you will get healthy plants and generous harvests, all 100% naturally! 🌿🌸

⚠️ Note : A white felt-like layer resembling mold may appear on the surface of the soil after applying organic fertilizers (BioGrow/BioBloom). No worries: this is the mycelium of beneficial fungi breaking down organic matter. This mycelium improves the microbial life of the soil and the availability of nutrients for the roots. **Do not remove it** – it will disappear on its own after a few days, once its role is fulfilled. ✅
