Install method:

1) Install height:  0.6-3M

2) Install distance: 4M ± 2M

Caution !

1.Indoor used only

2.Don’t use in dripping water or dripping irrigation place to avoid light damage.

3.The led grow light lighting time plus sunlight lighting time should be 10-14hrs.

4.There is an old saying ‘too much water drowned the miller’.

No time to rest and digestion-absorption, it will affect the growing speed.

Growing tips :

LED grow light provides a different light spectrum to your plants, thus modifying their needs. Here are some recommendations to follow in order to obtain a good crop with LED grow light -Given that the LED grow lamp emits much less heat than other light sources, your plants will need less water. Wait for your soil to dry a little bit before watering or at least make sure your plants really need to be watered. -Temperature is a very important element in the photosynthesis process. For the same reason as the previous point, maintain the ambient temperature between 20ºC-30ºC (68ºF-86ºF) for normal plant growth. -With LED grow light, your plants may need fewer nutrients. -For better light penetration, it is preferable to light several small plants rather than a few large ones -For some plant species, a reduced photoperiod may improve flowering.

Remarks:

The lighting area reduced from 84.7 square meter to 13.5 square meter when the hanging height lower down for 3 meter to 1.2 meter high. But the photon flux density increased 4.35times.

When you plants need more light please lower down the height. The light wouldn’t burn the plants even close to the plants.
