| Seedling | 100 – 250 µmol/m²/s |
| Vegetative | 400 – 600 µmol/m²/s |
| Flowering/Fruiting | 600 – 900 µmol/m²/s |
Optimal Light Duration
Light duration is key for plant growth. Proper timing helps plants grow strong and healthy. It affects how plants produce food and flower.
Knowing the right amount of light can boost plant growth. This guide helps you understand the light needs for different growth stages.
Photoperiod For Vegetative Stage
In the vegetative stage, plants need more light. This helps them grow leaves and stems. The right photoperiod is important for this stage.
- 18 hours of light per day is ideal
- 6 hours of darkness for rest
- Use LED lights for energy efficiency
Light Cycles For Flowering Stage
During flowering, plants need less light. This change signals them to produce flowers. Adjusting the light cycle is crucial in this stage.
| Light Duration | Dark Duration |
| 12 hours | 12 hours |
| 10 hours | 14 hours |
Positioning And Distance Of Lights
Lighting is very important for fast-growing plants. The position and distance of lights affect plant health and growth.
Placing lights too close or too far can slow growth or cause damage. Finding the right spot is key for strong plants.
Preventing Light Burn
Light burn happens when plants get too much light or heat. This can make leaves turn yellow or brown.
Keep lights at a safe distance to avoid burning. Different lights need different distances based on their strength.
- Use a ruler or meter to measure the distance
- Check plant leaves often for signs of burn
- Adjust the light height as plants grow taller
- Follow manufacturer guidelines for each light type
Maximizing Light Coverage
Plants need even light to grow well. Position lights to cover all parts of the plant.
Use reflectors or multiple lights to spread light evenly. Move lights as plants grow to keep good coverage.
- Place lights above the center of the plant group
- Use wide-angle bulbs or LED panels for broad light
- Adjust light angles to reduce shadows
- Keep light sources stable and secure
