Greenhouse Grow Lights

Design to the deficit, not to a fixed setpoint. The number that matters under glass is the daily light integral your crop needs minus what the glass actually delivers. That gap moves with season, latitude, glazing, shading screens and how dirty the roof is. Send us your location, glazing type and target DLI and we will work the deficit with you before specifying anything.

Complement daylight rather than repeat it. The DS320G's spectrum is shaped for this: a blue peak near 450nm, a broad 540–660nm band, then a red peak near 690nm with a far-red tail. Daylight under glass is already strong through the middle of the band and weak at the ends, particularly in winter and at the shoulders of the day — pushing the red peak longer and extending the far-red tail puts energy where the glass is not.

Dim against the day, don't switch against it. The DS320G dims 0–100% across the full grow and flower cycle. Run it up as natural light falls and back as it returns. Grouped through the GC001, a house is scheduled by zone with sunrise and sunset ramps of 1 to 60 minutes rather than hard on/off steps — which matters more under glass than in a sealed room, because the crop is already tracking a natural transition.

Narrow fixtures shade less. The DS320G is 31.89 inches long and 3.35 inches wide, and concentrates its 896 µmol/s into a 2ft × 3ft flowering strip rather than spreading it over a floor. Under a gutter you are lighting a defined row, and a tighter strip at higher intensity is usually the right trade.

Light the bench, not just the roof. Where the roof structure will not take fixture loads — or where benches move — an extended bench frame carries the lighting on the bench structure itself. That is a standard option on our rolling benches, and it removes the roof from the problem entirely.
