I love vertical. I just switched last year so this is my 2nd go at it. The room runs quite a bit cooler without the big horizontal reflector. Plant height is no longer an issue for me, but I still have to try and maintain uniform height if possible. This particular crop has some colas well above the base of the lamp. I'm going to try and even the plant heights with some training. Hey, you're the one who prompted me to up my root mass for the next crop, we were talking about root mass and yield . I think the plants are gonna love the 5 gal pails.
