I would like to give my opinion on the PJ300 LED Grow light.
I'm not a professional grower. I've been growing cannabis for about 2-3 years now. So far I've had about 4-5 harvests.
At the beginning I was using a standard HPS 400W lamps. However, these lights make cooling the tent very difficult. Also, after the first harvest I was already receiving a much bigger electrical bill than the usual. Then I decided to give it a try with LED lamp models.
In the following clip you can see results I achieved with the PJ300 LED Grow Light
