Venture Sunmaster Dual spectrum HPS 250W combination lamp.
This special plant lamp is a so-called combination lamp. This means it is suitable for both the growth phase (vegation phase) and the flowering phase. Combination lamps are generally used when the budget is limited. Optimal conditions are only achieved if different (=optimal) light sources are used in the growth phase and in the flowering phase.
It is a sodium vapour lamp.
Important! This offer only includes the illuminant.
For operation is also necessary:
- a suitable ballast fitting or ballast unit (the wattage of the ballast unit must match the lamp)
- one reflector
- an E40 socket
In our shop you can put together everything individually. If you are not sure, then take a look at our NDL complete sets.
What are NDL and MHL-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 LSR (fluorescent tubes) are usually used (also available in our shop).
For the growth phase, a lamp with an increased blue component should be used.
During the flowering phase, a lamp with an increased red light component should be used. 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.
Grow Guru Tips for NDL lamps
Tip no. 1: When using NDL 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.
