Grow Tip

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

Germination: 24" Seedling: 24"-30" Veg: 18"-24" Flower: 12"-18"

4.Recommended Lighting Time

Veg: 18/6(on/off) or 20/4(on/off) Flower: 12/12(on/off)

5. Recommended dimming level

Precondition: hanging distance at 12’’-18’’

Germination: 30%; Seedling: 50%-75%; Veg: 75%-100%; Flower: 100%

6.Recommended Growing Conditions

The rate of photosynthesis and transpiration is 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 airflows to replenish CO2. PH is 6-6.5. You may add more calcium and magnesium than normally needed.

7.Please Note

The light may be too strong, please wear your sunglasses when looking at it.

Some LEDs seem dim. They are IR. The human eye can not see IR very clearly, but you can wear sunglasses to check.

Please be careful not to sprinkle the nutrient solution on the light board, it may cause corrosion of the light board.

For DWC, the best PH is around 5.8
Between the range 5.5-6.0.

I'm using an SP 3000 with seedlings that are 4 days old. I'm trying to set the light height and brightness correctly. The recommended hang height for seedlings is 24" to 30". Item 5, dimming level, states "precondition…12" to 18" " and then gives 50% to 70% as the recommended value.
If I set my light at 50% to 70%, what is the hang height?
