3)The led grow light lighting time plus sunlight lighting time should be 10-14hrs.
There is an old saying too much water drowned the miller. No time 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.
