We’ve done the hard yards measuring light intensity at different distances, so we can tell you exactly which setting is best for your plants! We recommend for most plants to aim for at least 12 hours on and 8 hours off for optimum conditions.
too much light?
There are some tell tale ways that you can see if you've overcooked your light intensity:
- Burn marks on the leaves; this should only happen if the light is touching the leaves, or if you’ve got very sensitive plants
- Crispiness / browning edges
- Drooping leaves
not enough light?
Similarly, there are signs that your plant isn’t getting enough light:
Plants primarily require blue and red light between the 400-500nm and 600-700nm wavelengths - which corresponds to the blue and red wavelengths of light respectively.
Other portions of the light spectra are not always utilised by the plants! Which is why if you got a household light globe, it could grow a plant, but most likely wouldn't, as most of the light spectrum emitted is wasted by emitting light at the wrong wavelength.
Blue Light (400-500nm) encourages photosynthesis and leads to bushier plants that don’t stretch to find more light. Good for growing in compact spaces.
Red Light (600-700nm) tells the plant that it’s time to flower or fruit. Often plants under redder light will stretch and grow longer rather than growing short and bushy.
These lights utilise both the red, blue, and full spectrum light frequencies, to create an optimised growing experience for plants and a more desirable light colour for people.
