Basically, you can know that your grow lights are working if your plants look overall healthy. Also, if they grow at the appropriate rate and if they start flowering when they’re supposed to. But, ultimately, you will know your plants are getting enough light if the yield is good and the fruits are healthy. If you have the knowledge and the resources, you can perform scientific tests on the leaves or fruits. This way, you will find out if they are healthy enough.  However, this is a beginner’s guide. You should only look for obvious signs of malnutrition to know that your plants aren’t getting enough light.
