Plant Bulb Help!!!

[ERKleRose]

sooo, would a quad fixture from arcadia be good? It has a plant growth bulb 6500k, a 12% uvb

The Arcadia fixture doesn’t have a reflector for each bulb, cutting down on light and uvb strength, unlike what @dshuld suggested above. A 12% uvb is way too high for a 2’ by 2’ by 4’ tall cage that isn’t extremely densely planted, go with a 6%

Okay cool i’ll go for the 6%

This may give you an idea on why the 12% in the arcadia/ odyssea fixture. This was posted by Todd on fb.

And an example of why the spd charts are needed. Care to take a stab at which one on this chart this led is?
