Light schedule help from seedlings to harvest?

Most people do 18/6, they can also do very well under 20/4.

ViparSpectra has a few tips for you on this topic. First ViparSpectra has a chart for your reference to be consistent with the phases of different plant types.

Seedlings - You will need to hang the light high due to the delicate nature of seedlings. We recommend a break-in period of about a week while a seed has broken the surface. The first set of real leaves should be present while the seedling has been above ground for about a week.

Clones - Clones are a little bit hardier than fresh seedlings, but still, need to be given gentle light as they are entirely rootless when first cut, and need to conserve energy and moisture to transition into a rooting stage.

Vegetative - The deeper red spectrum is utilized less by the plant than when it is in flower. It uses high levels of white light that are essential for creating lush, thick plants that have tight internodal spacing and minimal stretching.

Flowering - The plant has much work to do and is preforming many complex biological processes in producing flowers and fruits. Because of this, the plant now requires large amounts of light.

Late Flower - Most rapid development has stopped, and the plant is gearing up for the scene in which the large flowers and fruits will mature or ripen.

If you expose plants to high light intensities too early in the crop cycle, you can damage chlorophyll pigments causing photo-oxidation (photo-bleaching), so we recommend slowly increasing your light intensity as your plant develops.

Based on the chart, we advise to run 18/6 for from seedling/clones/mother plants to vegetative stages, and run 12/12 for flowering stages for ViparSpectra KS3000 light.

24/0 for seedlings and clones;
18/6 for veg cycle and autos;
12/12 for flowering photo ladies.

Do you agree with that?
