Are white lights better than pink? I have pink lights 50 watt suppose that’s why my plants are growing so slow. What about yellow lights

Listen to those first three dudes, on lighting, if you just have the pink light, add another light that can bring another wavelength so you covering all aspects you want something that puts outs color 2700k-3k during the flowering side and and 3500k-5k during veg and mix the two together for best result.

White lights, especially those in the blue-white spectrum, are generally better for plant growth as they mimic natural sunlight. Pink lights, often associated with certain LED grow lights, can be effective but might not provide the full spectrum of light plants need for optimal growth. If your plants are growing slowly under pink lights, it could be due to a lack of specific wavelengths they require. Yellow lights, on the other hand, are not ideal for the vegetative phase as they lack the blue spectrum crucial for photosynthesis. Consider switching to a full-spectrum white light or supplementing your setup with additional blue light if possible. This adjustment should support healthier and faster plant growth.

It's all about the spectrum, most new led lights use top bin diodes that produce multiple different waveforms of light. When blended they seem like natural light. But it depend on the manufacturer and the waveform of light the diodes makes. Many of the old burple lights have made top tier bud. It can be done not as good or more importantly as efficient as today's LEDs but they did and do work. Please consider me as the answer to your question so I can be entered for a chance to win grower of the month contest 🙏 please and thank you 😊

Light is a critical factor in cannabis cultivation, and the color of the light (spectrum) can influence plant development significantly. Different wavelengths (colors) within the light spectrum encourage various biological processes and developmental phases in the plant. Let's delve into the different light colors and their impacts on cannabis plants: ### Pink (Purple) LED Lights: - **Composition:** Pink or purple LED lights are often a combination of red and blue LEDs. - **Benefits:** - **Blue Spectrum:** Promotes vegetative growth, encouraging bushy development and tight internodal spacing. - **Red Spectrum:** Essential for flowering and fruiting stages, helping the plants to produce buds. - **Drawbacks:** - Might lack a comprehensive light spectrum, omitting certain wavelengths that plants utilize. ### White LED Lights: - **Composition:** White LEDs generally provide a full spectrum of light, which means they emit a broad range of wavelengths across the visible spectrum and sometimes into the ultraviolet (UV) and infrared (IR) spectrums. - **Benefits:** - **Full Spectrum:** Mimics natural sunlight, which can be beneficial for plant development throughout all growth stages. - **Balanced Growth:** Encourages balanced growth in both vegetative and flowering stages. - **Drawbacks:** - May not be as energy-efficient as colored LEDs. ### Yellow LED Lights: - **Composition:** Yellow light is generally considered part of the warm white spectrum. - **Benefits:** - May encourage robust flowering due to its closeness to the red spectrum. - Can be softer on human eyes compared to the harshness of pink/purple LED lights. - **Drawbacks:** - Might lack the blue spectrum necessary for optimal vegetative growth. ### What to Consider When Choosing LED Lights for Cannabis: 1. **Growth Stage:** - **Vegetative Phase:** Requires more blue light to promote healthy, compact vegetative growth. - **Flowering Phase:** Requires more red light to stimulate bud production. 2. **Energy Efficiency:** - LED lights are generally energy-efficient, but comparing different models for their power usage versus light output (PPFD) is vital. 3. **Light Intensity:** - Higher wattage and higher PPFD values (photosynthetic photon flux density) will provide more light energy to your plants, which is crucial, especially in the flowering stage. 4. **Light Spectrum:** - A broad, full spectrum, or tunable spectrum LED light is generally preferred to optimize light delivery throughout all growth stages. 5. **Space:** - Ensure the light can adequately cover the growing area. A light that is too weak may not provide enough energy for healthy growth and bud development. 6. **Budget:** - There are various LED options available ranging from budget to professional-grade lights. Choose the best light you can afford to ensure quality and reliability. ### Final Thoughts: - **50 Watts:** Depending on the size of your growing area, a 50-watt light may or may not be sufficient. Cannabis, especially during flowering, requires a lot of light energy. Ensure your lights provide enough intensity and coverage for the growing area. - **Slow Growth:** Various factors can contribute to slow growth, such as nutrient issues, environmental conditions (temperature and humidity), and indeed, inadequate lighting. - **Upgrading Lights:** If you suspect your lights are limiting growth, consider upgrading to a higher wattage LED light or one with a more suitable spectrum for cannabis cultivation. Remember to adjust other environmental factors (like nutrients and humidity) when upgrading your light to optimize overall growing conditions and support your plants in utilizing the enhanced light levels effectively.

a warmer white light is probably best, but for the most part, how much light you give is the vastly more important factor. guesstimating efficacy of what you have, i'd say that 50w can only cover little over 1 sq ft on a 12/12 cylce and 150% of that area over 18/6 (only relevant for an autoflower). your light is only a reason for slow growth if it is giving a low "DLI" (daily light integal) .. compacted substrate, nutes that require chelation/fixating before the plant can use it etc...
