Which grow lamp for which grow box area

What light is needed during the growth phase?

In order to develop well in the vegetative phase, your plants primarily need light in the blue color spectrum. Overall, one can speak of a spectrum of around 4000 – 8000 Kelvin, although lamps with around 5000 – 7000 Kelvin have proven to be ideal. A very precise color spectrum can be achieved with LED technology; TLEDs such as the Secret Jardin TLED Growth with 42 watts can be combined and distributed anywhere in the grow box due to their low weight . Metal hydride lamps are well suited for conventional lighting concepts , but they consume significantly more electricity.

Which light is suitable for the flowering phase?

In order for the plants in your indoor grow to produce strong flowers with delicious terpenes, they absolutely need light in the red color spectrum. Wavelengths of 2500 to 3500 Kelvin are ideal here. For this color temperature you can use sodium vapor lamps or several LED light strips . According to the latest findings, the additional use of the Far Red spectrum (approx. 730 nm) is very beneficial for plant development. Far-red LEDs are now increasingly being installed in full-spectrum LED lamps.

What are full spectrum LEDs?

Modern LED technology makes it possible to combine the entire light spectrum that your plants need from young plants to flowering in one grow lamp. The use of LEDs with different wavelengths ensures a balanced color spectrum, although for LED grow lamps the color spectrum is usually not specified in Kelvin, but in nanometers (nm). Full spectrum LEDs usually have a range of approx. 400 – 780 nm (including Far-Red), some models such as. B. the Greenception GCx series from Greenception even offer a portion of UV-A.

How can you save costs with LED technology?

Compared to conventional MH and NDL lamps, the last generation of LED grow lamps allowed energy costs to be saved on average by up to 30%. The efficiency of the individual LEDs is of course constantly being improved, current models such as B. a Lumatek Zeus Pro 600W with a light efficiency of 2.9 µmol/J already moves towards 40% savings potential. In addition, LEDs can be easily dimmed without losing efficiency. This significantly saves electricity costs when raising young plants and during the growth phase.

Which lamps are good for cultivation?

There are now excellent LED and LSR lamps specifically for very young plants and propagation from cuttings. They give off little heat and have no hotspots. This protects the sensitive young plants and ensures successful rooting. In the area of ​​fluorescent tubes there are complete fittings such as: B. the Lightwave T5 cutting fitting or ready-made LED solutions such as the Cosmorrow LEDs from Secret Jardin. There are also practical double power supplies that can be used to directly power two LED light strips.
