Grolux Sylvania Grow Lamps/Bulbs-Dual 400W

Grolux Sylvania - Single Lamp System - 250W - 400W - 600W

At different times in the growing cycle, plants require different types of light radiation. Immature plants have different needs to those about to mature.

To maximise the potential of a plant and ensure that it grows strong and healthy, you need to deliver just the right kind of light radiation. These bulbs have been colour adjusted, so unlike normal dual spectrum lamps, these generate a greater volume of blue than standard bulbs which helps promote growth during the vegetative and flowering phases.

Although these lamps are produced to an extremely high standard, the performance will drop off over time. We recommend you replace lamps every 6 months to avoid diminishing harvests.
