How to Produce Hydroponic Forage Using Disposable Plates

Introduction to Hydroponic Forage

• Jesús introduces himself and the topic of producing hydroponic forage using disposable plates, aimed at those with budget constraints or skepticism about hydroponics.

Materials Needed for Production

• The essential materials include water, a sprayer, cloth, disposable plates, household bleach, a colander, and corn grains.

• Emphasis on selecting high-quality seeds: they should not be broken, rotten, or infested with insects to prevent fungal and bacterial issues.

Seed Preparation Process

• Importance of avoiding treated seeds (with pesticides), which are often identifiable by their color (red or green in Mexico).

• Remove impurities from grains; floating debris indicates bad seeds that need to be discarded.

Disinfection and Soaking Seeds

• After cleaning the seeds, soak them in a chlorine solution (2 ml per liter of water) for 15 to 30 minutes. Over-soaking can damage the seeds.

• Highlighting temperature control: the environment should not exceed 30°C to avoid fermentation and spoilage.

Germination Conditions

• Seeds must be kept out of direct sunlight initially; they require darkness for optimal germination during the first days.

Nutritional Considerations

• Hydroponic forage is a supplement in animal diets due to its low fiber content despite being rich in protein, vitamins, and minerals. It should complement other feed sources.

Final Steps Before Germination

• After soaking for 15–30 minutes, drain excess water using a colander.

• Add more water before leaving the seeds to soak for an additional 24 hours; this allows them to absorb moisture necessary for germination.

Preparing for Planting

• Ensure that after soaking for 24 hours, the seeds are placed in germination trays while keeping them away from direct sunlight.

Hydroponic Green Forage Production Process

Introduction to Hydroponic Forage

• The process begins with draining water and observing the difference in seed size before and after soaking for 24 hours, which increases their volume.

Preparing Seed Trays

• Holes are made in disposable trays; three holes at the bottom of square trays and multiple holes across other types to allow drainage.

• It's crucial not to remove water from the trays as stagnant water can ferment seeds, leading to spoilage and mold growth.

Seed Placement and Quantity

• Seeds are placed in the prepared trays, with a recommended layering of 2 to 3 layers depending on seed variety.

• Damaged or broken seeds should be removed before planting. Experimentation with different tray quantities is encouraged.

Watering Techniques

• Typically, an automated irrigation system is used; however, manual watering will be done using a sprayer for this demonstration.

• Manual watering requires maintaining moisture levels through cloth coverings during initial days for hydration.

Importance of Darkness in Early Growth

• Keeping seeds covered with cloth allows gas release while preventing light exposure, which promotes root development during the first six days.

Maintaining Tray Positioning

• Trays should be inclined slightly to prevent excess water accumulation; small objects can be used to achieve this angle.

Watering Frequency and Methodology

• Recommended watering frequency is two to three times daily. If busy, at least once in the morning and once in the afternoon is necessary.

Observations After Initial Days

• After 48 hours, roots begin sprouting from seeds. Variability in growth rates among seeds is normal.

Phases of Hydroponic Forage Growth

• The production process consists of two phases:

• Phase One (Day 1 - Day 6): No light required; darkness aids root and stem growth.

Hydroponic Corn Growth Conditions

Optimal Temperature for Hydroponic Corn

• The ideal temperature range for hydroponic corn is between 25 to 28 degrees Celsius. Exceeding 30 degrees can lead to seed fermentation and fungal issues.

• If temperatures drop below 25 degrees Celsius, the growth rate of the plant slows down significantly due to a reduced metabolic rate.

Initial Growth Stages

• Five days after planting, the hydroponic corn has developed strong roots suitable for lifting as a single piece; however, caution is advised to avoid damaging the roots.

• Initially, a cloth or fabric is used to keep seeds hydrated; once roots are established, normal watering practices can resume while keeping plants in darkness for optimal growth conditions.

Light Requirements During Germination

• The first leaves typically emerge around day six or seven; at this point, plants require some light but not direct sunlight as they are still in the germination phase. Optimal light levels range from 2,500 to 3,000 lux for young seedlings.

• Direct sunlight exposure can exceed 100,000 lux which is too intense for germinating plants; thus maintaining appropriate lighting conditions is crucial for healthy development.

Observations on Plant Development

• After nine days of growth, plants show significant progress with their first leaves fully unfurled and some beginning to sprout second leaves. Color changes indicate healthy growth patterns.

• Root health is critical; if dehydration occurs (evident by drying edges), it may be necessary to adjust environmental factors like airflow and light exposure to prevent stress on the plant.

Harvest Timing and Nutritional Considerations

Hydroponic Forage Production and Animal Feeding

Metabolism of Plants in Controlled Environments

• The metabolism of plants is significantly influenced by sunlight; it increases when the sun rises and decreases as it sets, highlighting the importance of light exposure.

• In fully controlled environments, plant metabolism can remain active 24/7, contrasting with rustic production methods that limit growth due to uncontrolled factors.

Growth Timeline and Conditions

• Hydroponically grown plants can reach a height of 20 to 25 centimeters within approximately 11 days, emphasizing the efficiency of this method compared to traditional farming.

• It is crucial for seeds to be free from fungi and bacteria to ensure healthy growth; this impacts the quality of forage produced for animal consumption.

Implementing Hydroponic Forage in Animal Diets

• Different strategies exist for incorporating hydroponic forage into animal diets; organic production focuses on enhancing egg and meat quality through free-range practices.

• Animals may show varying preferences for hydroponic forage based on seasonal availability, affecting their feeding behavior and overall health.

Recommended Feeding Practices

• A table outlines recommended dosages of hydroponic forage per 100 kg body weight for various animals: dairy cows (1-2 kg), dry cows (0.5 kg), beef cattle (0.5-2 kg), pigs (2 kg), and poultry (25 kg).
