Hydroponics & Horticulture: Modern Farming Techniques 101

Identify the major hydroponic system components: growing chamber, reservoir, submersible pump, delivery tubes, and optional grow lights, while understanding system types and design factors for a successful harvest.

Explore how water quality, air exchange, light manipulation, climate, and nutrients shape hydroponic system design, including methods like DWC and NFT and algae prevention.

Explore hydroponic mediums and learn to select the best growing medium for your plants and conditions, boosting health and yields. Support roots with moisture and oxygen; reduce soil-borne illnesses.

Evaluate a growing medium that retains water and nutrients with proper drainage to prevent root rot. Ensure it provides adequate air circulation, high CEC, stable pH, and pathogen-free, affordable availability.

Explore growing media types used in hydroponics, comparing advantages and disadvantages of perlite, vermiculite, coco, coco peat, rockwool, leca, sand, and gravel.

Assess hydroponic water quality to support optimal plant growth, quantify purity with electrical conductivity, pH, and total dissolved solids, and fix issues through a practical water management strategy.

Master hydroponic water quality through regular testing and water changes, monitoring pH, oxygen, EQ levels, and temperature. Discover how RO filtration, aeration, and water management prevent contaminants and stagnant water.

Learn how to quantify hydroponic water quality using pH, EC, and TDs, with test strips and digital meters for accurate, practical monitoring in home to commercial setups.

Learn how to create and mix hydroponic nutrient solutions with macronutrients, secondary nutrients, and micronutrients, manage pH and electrical conductivity, and diagnose deficiencies to optimize growth.

Explore hydroponic nutrient solution types, comparing synthetic and organic options, their ingredients like fish emulsion and compost tea, forms (liquid vs. powder), and cost considerations to meet plant needs.

Explain how water pH controls nutrient availability in hydroponic systems, using the 0–14 scale and 5–7 range. Show how alkalinity and buffering capacity affect pH stability and acid adjustments.

Explore electrical conductivity as a measure of dissolved solids in hydroponic nutrients, maintain EC between 1.5 and 2.5, and learn to mix N–P–K solutions with pH 5.5–6.5.

Identify common hydroponic nutrient deficiencies and their solutions, including nitrogen, phosphorus, potassium, calcium, magnesium, iron, and zinc, and note symptoms such as yellowing leaves and stunted growth.

Explore factors essential for plant growth, including light for photosynthesis and energy, water for nutrient transport, soil quality and pH, nutrients, temperature, and air circulation.

Explore the photosynthesis process where plants use light and chlorophyll to convert carbon dioxide and water into carbohydrate and oxygen, with rate influenced by solar irradiance and stomata activity.

Explore how soil and water pH shapes plant growth by defining acidity and alkalinity on a 0–14 scale, with most plants thriving at pH 6–7.5 for nitrogen, phosphorus, and potassium.

Identify suitable plants for hydroponic systems, master seed germination, and apply spacing and pruning to optimize growth through all growth stages while managing nutrient needs, pH, and light.

Learn to germinate hydroponic seedlings externally using moisture, warmth, and light with rockwool cubes, then transplant sprouts into the hydroponic garden and nourish with nutrient solution.

Space plants 18–30 inches in hydroponics to maximize light, air flow, and growth; prune to balance vegetative and reproductive growth, remove dead or diseased branches, and improve yields.

Explore what a greenhouse is and how hydroponic greenhouse systems operate, detailing cooling and heating methods, materials, steps to build, plus selecting suitable plants and recognizing benefits.

Learn how a hydroponic greenhouse operates by delivering nutrients directly to the root zone in growing medias, with climate control, ventilation, and polycarbonate light diffusion for optimal growth.

Explore how hydroponic greenhouses boost water efficiency with timed watering and recirculation, reduce pests through a controlled environment, and enable year-round, high-quality yields with automation.

Build a hydroponic greenhouse for indoor or outdoor year-round growing, using NFT or DWC, with climate control. Plan layout and maintenance to optimize pH and nutrients.

Maintain optimal greenhouse temperature and humidity through cooling and heating systems. Employ natural and mechanical ventilation and evaporative cooling, with electric, gas, or hot water heating, and monitor conditions.

Explore system types for hydroponic greenhouse gardening, including cold frame, freestanding gothic arc, and gutter connected greenhouses, and compare costs, year-round use, height constraints, and production scalability.

Hydroponic greenhouse farming yields more under a controlled, water-efficient system. The lecture lists suitable plants like strawberries, tomatoes, lettuce, mint, basil, cabbage, peas, and cucumbers, with depth and temperature considerations.

Identify common hydroponic pests and diseases, from spider mites to powdery mildew, and implement preventative hygiene, regular monitoring, and beneficial insects to protect plant health.

Explore beneficial insects, including ladybugs, lacewings, predatory mites, and bees (including mason bees), for pest control and pollination in hydroponic systems, managing whiteflies and spider mites.

Explore the economic aspects of hydroponic farming, including urban viability, up to 90% water savings, year-round production, higher yields, costs and market demand, sanitation, and harvesting timing.
