I wished I would have known I couldn't later change the number of stars in review before I left them. I tried to be neutral because of my inexperience but this product likely deserves a better rating. I love this light and the TS 600 I was using before. However, I did have some issues with the plant that could possibly be from too much light after changing to TS 1000 in my 2x2 tent... I'm just not sure. I'm really thinking about upgrading to a 3x3 tent for my next grow. That said, both the TS 600 and the TS 1000 is a lot of quality, full spectrum light for the money.
