Am currently setting up a tent grow 2.8 x 1.4 x 2 and will be using 3 x 600w lights consisting of digital lumatek ballasts and gavita digital globes and want to know should I decide to hang the lights horizontal rather than virtual with no shades should I use 6" cool tube with white or silver reflectors or 6" air cooled horizontal hoods similar to sun master 2. Look forward to everyone's experience Ganga Sent from my iPhone using GC Forum
