    Default Unsure now

    Wanted to grow LED but after reading this i became unsure...


    "5000 to 8000/ Deep blue/ Encourages excellent leaf and stem growth.

    4000 to 5000 / Light blue/ Encourages good leaf and
    stem growth.

    4000/ Neutral white/ Promotes normal growth.

    3700 to 4000/ Warm neutral/ Promotes rapid growth.

    3000 to 37000/ Warmer yellow neutral/ Highly active
    photosynthesis for all stages of growth.

    1500 to 3000/ Hot orange or red/ Promotes flowering

    For cannabis, 6500k is the ideal spectrum for vegetative growth. Now this doesn't mean the plants wont grow under other specs, it just means they will do best at 6500k. in flower, cannabis does well with warm specs, 2300-2800k is ideal for maximum bud production"

    When buying invisible sun led panels I have to choose between 2700/3000/3500/or 4000k range depending on model which I assume means I am making a compromise on the ideal Kelvin range for each stage of growth...

    Meaning perhaps it's better just to buy mh and hps, catering then to both cycles

    Its the predominant colours in each of those temperatures that do some of those things. Its not the temperature itself since that contains all colours so that text could be much informed better.

    3000-3500K covers the plant action spectrum fully and has the correct ratios of each colour. This middle temperature is 80-90% as accurate as sunlight, compared to hps 20% for example.
