Kweekotheek: The knowledge base for home growing

Home growing starts with creating a controlled environment where you can precisely manage light, temperature, and humidity. You begin with a suitable grow light, optionally choose a grow tent or grow box, and ensure good ventilation and extraction in your grow space.

Then you set up a light schedule and keep the climate stable. By properly controlling these factors, plants grow faster and healthier. Start simple and optimize step by step. A stable foundation ultimately leads to the best results.

To start successfully, you need a number of basic components that together create a stable growing environment.

The most important components are a grow tent, LED grow light, extraction system with carbon filter, fans, a timer, and a climate meter. With these, you can optimally regulate light, air, and temperature. A complete setup prevents beginner mistakes and ensures a better start.

The right size grow tent depends on your space and how many plants you want to grow.

• 60x60 cm → ideal for beginners
• 80x80 / 100x100 cm → most chosen
• 120x120 cm → for larger setups

Choose a size that fits your space, so you can grow efficiently without unnecessary energy consumption.

For the growth phase, plants primarily need blue light to stimulate strong and compact growth.

LED grow lights are most suitable for this because they are energy-efficient and often have an adjustable spectrum. This allows you to adapt the light to the growth phase. A good LED lamp provides better control and lower energy costs.

The required wattage depends on the area you want to illuminate.

• LED: ± 200–300W per m²
• HPS: ± 400–600W per m²

The correct wattage ensures that plants receive sufficient light without wasting energy. Too little light inhibits growth, while too much light unnecessarily increases costs.

Plants need different light schedules depending on the growth phase.

• Growth: 18 hours light / 6 hours dark
• Flowering: 12 hours light / 12 hours dark

A consistent light schedule ensures stable growth and better yield.

The correct distance between lamp and plant prevents damage and ensures optimal growth. On average, an LED grow light hangs between 25 and 50 cm above the plants.

Too close can cause burning due to high light intensity, while too far away results in less growth. Always pay attention to how your plants react and adjust the height if necessary.

LED lighting is currently the best choice for most growers.

LED lamps are energy-efficient, produce less heat, and last longer. This makes them more efficient and easier to use than HPS.

HPS is still used, but is less suitable for modern setups.

A stable climate is essential for healthy growth.

• Temperature: 20–28°C
• Humidity: 40–70%

By keeping these values stable, you prevent stress and growth problems.

Yes, ventilation is essential for a healthy growing environment. It provides fresh air, removes heat, and prevents moisture buildup.

Without ventilation, plants may grow poorly and problems can arise more quickly.

A carbon filter removes odors from the air before it is exhausted. The air is passed through activated carbon, which absorbs odor particles. This prevents odors from spreading outside the grow tent.

On average, you water plants 2–3 times a week, depending on temperature and humidity. In a warm grow tent, water evaporates faster, requiring more frequent watering.

Let the top layer of the soil dry out slightly before watering again. Overwatering is one of the most common mistakes.

The costs are on average between €20 and €60 per month. This mainly depends on lighting and usage.

LED lighting helps to save energy and reduce costs. With an efficient setup, you can keep costs well under control.

Use energy-efficient LED lighting, set timers correctly, and ensure efficient ventilation. Unnecessary energy consumption often arises from incorrect adjustment. By coordinating everything properly, you work more efficiently and save costs.

Poor growth is usually due to an imbalance in light, climate, or care. Too little light, incorrect temperature, or poor ventilation are common causes. By checking these factors, you can quickly solve problems.

Many beginners make the same mistakes. The most common are overwatering, an incorrect light schedule, and insufficient ventilation. These mistakes can strongly affect growth. Start simple and optimize step by step to prevent problems.

Modern grow systems are relatively quiet. Most noise comes from fans and extraction. With quality equipment and a good setup, this can be well limited.
