Vegetative-spectrum LED
Fixtures with the spectrum weighted toward 400–500 nm blue: a more compact plant structure, more shoots and plants ready to enter flowering with energy.

Coverage figures are indicative and depend on mounting height and the target PPFD of each phase. We calculate them from your real measurements. The renders are of the Mega Optic family and do not distinguish between the two power levels.
Vegetative vs. Full Spectrum
Full Spectrum works for everything. This spectrum works for this phase
A full-spectrum fixture replicates sunlight and performs at any stage. In growth, weighting the curve toward blue acts more surgically.
Full Spectrum
Versatile, for the whole cycle
Integrates wavelengths across the whole visible range, with a high proportion of red (600–700 nm) and far-red (700–800 nm). A single install covers mothers, growth and flowering.

Vegetative spectrum
Dedicated to the growth phase
Higher peaks at 400–500 nm, in sync with the other wavelengths. In early stages it delivers exactly the light signal the plant needs to grow compact and vigorous.

Both have their place. If your install is a single room that runs the whole cycle, Full Spectrum is the answer. If you have separate vegetation or mother-plant rooms, dedicating the spectrum to that phase is what raises yield.
Plant physiology
What blue does inside the plant
In growth the goal isn't uncontrolled elongation but a solid architecture able to support heavy flowering. Blue is the signal that directs it, in three steps.
Blue is captured
Cryptochromes and phototropins are photoreceptors that activate independently at each stage and absorb specifically in the blue band.
Cryptochromes · phototropinsThe stem stops stretching
Activating those receptors triggers photomorphogenic responses that inhibit excessive elongation: shorter internodes, thick stems and large leaves.
Photomorphogenic responseThe leaf opens and assimilates more
Blue stimulates proton pumping in guard cells, causing maximum stomatal opening: more CO₂ assimilated and faster photosynthetic rates.
Stomatal opening · CO₂What you gain
What changes in the room
Four measurable effects of dedicating the spectrum to the growth phase — in the plant and on the bottom line.
Compact structure and more shoots
Short internodes and thick stems give more shoot points on the same plant height.
More efficiency per watt
Energy and photosynthetic efficiency at once: the photons emitted are the ones the plant uses in this phase.
Less heat to dissipate
More controlled dissipation in the room, with all that means for the climate and the cooling equipment.
Fewer growth days
The phase is shortened with better final structure, and the plant enters flowering with maximum energy.
Applications
Where this spectrum makes sense
Dedicated vegetation rooms
Installations where the growth cycle has its own room. Not sharing space with flowering, the spectrum can be fully dedicated to this phase.
Mother plants and propagation
Mothers dedicated to producing cuttings: short internodes, thick stems and healthy leaves matter, not height. That's exactly what a blue-heavy curve produces.
