It is a metal halide lamp.
Please note: For operation, a suitable ballast fitting is necessary, and an E40 socket is also required.
What are HPS and MH-Grow lamps and how are they optimally used?
Sodium vapour lamps are normally only used in the vegetation and flowering phase. In the germination phase, ESL (energy-saving lamps) or LED are usually used (also available in our shop).
For the growth phase, a lamp with an increased blue component should be used.
A lamp with an increased red light component should be used during the flowering phase. This is particularly important because certain hormones in the plant lead to increased flower production.
The required power of the lamp is calculated according to the rule of thumb 400 W per m².
Metal halide lamps are well suited for the growth phase, as the plant is stimulated to rapid growth by the higher blue component.
What are the advantages of HPS / MH-Grow lamps?
The depth effect of a HPS is much better (see PAR value), which is why a HPS in the flowering phase is essential for a high yield.
What are the disadvantages of HPS / MH-Grow lamps?
HPS / MH lamps consume a lot of power and a ballast is required, which should be mounted outside the cabinet due to the heat generated.
Due to the heat generated by the lamp, care must be taken to ensure suitable temperature control and sufficient distance.
Grow Guru Tips for HPS lamps
Tip no. 1: When using HPS lamps we recommend a cooling device. The CoolTubes (available in our shop) are ideal for this purpose. CoolTubes are reflectors with integrated lamp socket that are connected to a ventilation system. Here, fresh air constantly flows around the lamp.
Tip #2: You're a beginner at Growing-Area? Then we recommend a complete set for beginners. The complete sets are available in different sizes, depending on the project size: 250 watts / 400 watts / 600 watts. We also have a complete set for the narrow purse (Low Budget Grow Set) in the offer. However, we recommend our complete set "Value". It is of higher quality and you will achieve better results.
