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 lamp. However, these lights make cooling the tent very difficult. Also, already after the first harvest I received 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.
