One of the most common questions of all thrown the way of those in the hydroponics industry is that of what exactly, if any, are the benefits of dual-spectrum grow lamps? They’re available in abundance these days and can pack a punch price-wise, but what are the actual concrete benefits of stepping up to dual-spectrum bulbs as an indoor gardener?

Well, in order to understand exactly why dual-spectrum grow lamps are advantageous, it’s important to first get a good grasp of how standard grow lamps do their job.

Blue or Red Spectrum

Head out to buy High Intensity Discharge (HID) grow lamps and what you’ll essentially be looking at is a choice of two very different grow lamps – one for the plant’s flowering stage and the other for its vegging stage. These two types of HID lamps are known as Red and Blue spectrum grow lights respectively, which if equal in terms of importance both carry out very different jobs.

Blue spectrum HID lamps for example are designed to provide plants with light from the blue end of the spectrum, which does a pretty impressive job replicating the effects of the blue skies of the spring and summer months along with sun’s energy from this time of year. Unsurprisingly therefore, these are the kinds of lights that are best suited to instances where fast and vigorous growth and development are required. 

As for red spectrum lamps, these are the lights that are designed to emit light from the red end of the light spectrum which effectively recreates the effect of the outdoors during the autumn months. It is during the autumn that plants cease focusing on growth and development, instead putting their energy into reproduction. So once again, when and where an indoor gardener is looking to encourage and bring about this switch, they tend to do so with red spectrum lamps.

Dual-Spectrum Lamps

So as you can probably see, while both of the above types of growing lamps are exceptionally important and can play a role in the cultivation and development of beautifully strong and healthy plants, they are also both somewhat limited in terms of how far their capabilities can stretch. As you may have figured out by now, when it comes to dual-spectrum lights what you are in fact looking at is a lamp which combines the necessary elements to provide both red and blue light from the same bulb. By covering all ends of the spectrum, these bulbs are uniquely able to provide plants which are grown indoors with every type of light they need to reach their full potential at any time of year.

In terms of convenience, anyone who has ever faced the hassle of trying to switch bulbs between vegging and flowering stages in rather cramped growing environments will wholly understand why dual-spectrum lamps make so much sense. And what’s more, investing in high quality dual-spectrum lamps in the first place will more often than not work out considerably cheaper than buying separate lamps for flowering and vegging stages.

When it comes to the actual plants themselves, the advantages of switching dual-spectrum lamps are far too numerous to list in full. Suffice to say however that from the promotion of larger leaf mass to higher levels of chlorophyll to encouraging into earlier flowering to improving fruit weight and generally benefitting yields in general, there’s a hell of a lot to be taken away by making such a simple and affordable switch.

Just be sure to invest in a quality dual-spectrum bulb in the first place from a brand you know you can trust and you’ll find it pretty difficult to go wrong.
