400W Metal Halide Bulb
Vegetative Growth & Mother Plant Specialist
This 400W Metal Halide (MH) conversion bulb is specifically designed for the vegetative stage and maintaining mother plants. It delivers a strong blue light spectrum that promotes excellent leaf development, tighter internodal spacing, and compact, bushy plant structure.
Key Features:
- Rich blue spectrum ideal for vigorous vegetative growth
- Encourages short internodes and strong, healthy foliage
- Reliable and consistent performance
- Compatible with 400W HPS or MH ballasts
- Effectively covers an area of 100cm x 100cm
Important Usage Notes:
- The bulb may take a couple of minutes to fully ignite when first turned on — this is normal behaviour.
- If using a digital dimmable ballast, do not dim or supercharge this bulb. It must run at full 400W only.
A great choice for serious growers looking to keep healthy mother plants and produce strong vegetative growth.
