6500k blue light during veg.
Best light for autoflowering plants.
Their color mimics the reddish light from the autumn sun.
Do autoflowers need darkness.
Blue light spectrums have been shown to encourage vegetative growth helping cannabis plants grow short and stocky while minimising stretching.
High pressure sodium lamps hps or high quality led lamps with a complete cannabis specific spectrum are used for the red light.
Master the best light schedule for autoflowering strains as a rule of thumb autoflowering marijuana plants can grow and reach maturity with as little as only 5 hours of light per day.
While the hps lamp is usually reserved by photoperiod strain growers for the bloom stage due to the high level of orange red light rather than blue white which is better suited for vegging plants the stockier autos won t stretch to the same degree under an hps.
Red light spectrums are ideal for bloom because they encourage budding and a little bit of stretch encouraging your plants to produce big dense flowers.
Supplying your autoflowering green beauties with only 5 hours of light cannot possibly grant you good results upon harvesting.
It is completely okay to give your plant yellow light for its whole life.
When autoflowering plants begin to bloom growers use a mix of different lamps that continue to provide blue light but also add red and infrared light.
But don t get this wrong though.
What s best for you.
Autoflowering plants as we have determined earlier grow best when you give them between 18 and 24 hours of light each day but there are many circumstances when a grower need to give his plants only 12 hours of light.
What light cycle is best for autoflowers.
18 6 light cycle the best light cycle for autoflowering plants.
When autoflowering plants start pre flowering growers should go to a mixed lighting program that retains some blue light such as metal halide mh but also add red and infrared spectrum by using high pressure sodium hps lighting or whole spectrum marijuana specific led lights such as those made by lush lighting.
