How to choose a plant growth lamp? Full spectrum?

Why is it always difficult and time consuming to make a decision when buying a plant grow light? Because many people will tell us that there are many factors to understand before buying: light intensity, consistency, spectrum, PPF, PPE, PPFD, Wattage and other jargon. With so many terms and concepts, it is easy to get confused, and the truth is that to make an informed choice you don't need to fully understand these terms. The following will simplify everything for you. All you need to do is a simple calculation based on the formula to get the most suitable product.

I. Focus on PPFD, not on PPE and PPF

Many people will say that PPE is the efficiency of the light and PPF is the amount of light from the lamp, which is true but has no practical meaning. This is because light is the actual light that the plant can receive and PPFD is the only indicator of how much light the plant canopy can receive. the PPFD value is not entirely controlled by PPF. So with regard to light intake, we only need to focus on the PPFD value. On the other hand, regarding energy efficiency: the actual electricity used by a luminaire is only related to its wattage. So when it comes to efficiency, we should focus more on PPFD/W, which represents the true efficiency of the luminaire and predicts the cost of long-term use. The smaller the value, the less electricity is consumed in the long term.

Ⅱ, are full spectrum grow lights the best?

Regarding the spectrum, why do people say they need the full spectrum? Because each plant and each stage of growth requires a different recipe for optimal light, and the full spectrum is like a buffet where the plant is left to choose. But this self-service format, being too free, does not get the best harvest. The best approach is to manually select the spectrum that best suits the plant, so that control enhances the certainty of the desired outcome. At the same time, many scientific experiments have shown that controlling the spectrum can control the characteristics of the plant, both in terms of morphology and the flavour of the harvest. Therefore, it is best to choose a tunable full spectrum. Incidentally, a full-spectrum grow light means that the simulated sunlight contains a mixture of all different wavelengths. It is impossible to reproduce 100% of the sun's light with actual artificial lighting, but plants really only need the following five types of light: red, far-red, UVA, deep red and blue-green. 600 Watt full-spectrum grow lights are becoming the preferred choice for indoor growing thanks to their customisable spectrum, cool light source and long life.

So about the spectrum, choose an adjustable broadband spectrum containing the above light wavelengths, why broadband light? Because the colour of the light, the colour of the mixture containing these lights is usually white rather than red, blue or purple, facilitating the observation of plants during growing and the timely detection of pests and diseases.

Based on the above concepts, it can be summarised in this set of choices.

1. Know the minimum and maximum PPFD requirements of the plant and select Plant Light that fits the interval.

2. judging the benefits by the cost of PPFD/W.

3. Optimise the selection by the adjustable full spectrum.

The Feton Smart Full Spectrum Grow Light combines full spectrum integrated lamp beads and a fully intelligent control system. Not only does it allow for spectral intensity control customisation, it also allows for automatic execution of lighting strategies. Using advanced technology to bring convenience to growers and improve yields.
