400W Metal Halide Conversion Bulb

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
  

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, compact clones and vegetative growth.
