- Grow Tips
1.How do I determine the right light for my grow area?
Measure the floor space. Multiply the length times the width and this will give you the square footage. You should be able to get decent results with 30-50 actual watts of power per square foot.
2.For larger areas should I go with a single large panel or multiple medium to small lights?
Using multiple lights allows you to better distribute the intense light in more areas of the grow space instead of having all of the higher intensity light concentrated in only one area while the outer edges never receive intense light.
3.Recommended Hanging Distance Above Plants
Seedling stage: 20''~28‘’ Veg Stage: 16''~20‘’ ;Flowering Stage: 10''~16‘’
4.Here are more tips for grow under our light:
Growth stage, turn Growth switch on. Bloom stage, turn Growth and Bloom switches on.
5.Recommended Lighting Time
Veg: 18/6(on/off) or 20/4(on/off) Flower: 12/12(on/off)
6.Recommended Growing Conditions
The rate of photosynthesis and transpiration are directly affected by temperature, humidity and airflow.
The perfect temperature and humidity for your plants are found between 75°-85°F and 50% - 70% humidity, with plenty of airflow to replenish CO2. PH is 6-6.5. You may add more calcium and magnesium than normally needed.
The light is not water-proof, so do not use it under water environment.
Light may be too strong, please wear your sunglasses when looking at it.
Some leds seem dim. They are IR. Human eye can not see IR very clearly, but you can wear sunglasses to check.
