Green Force 250W mixed-spectrum bulb. SOLUX for indoor growing . 250W HPS lamp, 2100K , E40 base, for use in vegetative and flowering stages . An efficient option for boosting cannabis plants in medium-sized grow tents with controlled temperature management.

The Green Force 250W bulb from SOLUX offers a remarkable balance between energy consumption and photometric performance in cannabis grow rooms. Its mixed spectrum integrates a blue/white component for the vegetative stage and a red/orange component to boost flowering, eliminating the need for mid-cycle lamp changes.
This is an HPS (high pressure sodium) lamp optimized to work with magnetic and electronic ballasts , offering stable ignition and consistent light output when reflector cleanliness, ventilation, and photoperiod schedules are respected.
The color temperature of 2,100 K promotes the formation of compact flowers, while the blue input helps to maintain controlled internodes and a firm plant structure during growth.
Easy mounting on reflectors with E40 thread, integration into medium-sized cabinets and use as a main source or side reinforcement alongside LED grow lights when PPFD uniformity in the canopy is desired.
The approximate lifespan of 32,000 hours allows for flexible maintenance planning; even so, it is advisable to record the installation date and replace it around 9 months of intensive use, since the depreciation of the flow is not always evident at first glance but impacts final production.
With proper thermal management, this lamp facilitates stable photosynthetic densities, improves light penetration at medium levels, and supports consistent flowering schedules in home grow tents and semi-professional projects.
In indoor growing , the 250W format is ideal for medium-sized grow tents where a balance between intensity and temperature is desired. The mixed spectrum supports the entire cycle: compact growth in seedlings and vegetative stages, a smooth transition to flowering, and a warm color during maturation that promotes dense bud production. In spaces with multiple grow lines, this wattage allows for combining several units to cover modular areas, adjusting heights and passageways to avoid harsh shadows.
As a lighting tool, this HPS stands out for:
This product offers a competitive price and an excellent performance-to-consumption ratio for medium-sized grow tents. The investment pays for itself through the continuous mixed spectrum and stability across successive harvests when maintenance and thermal management are followed.
