  1. first grow, got my scrog screen almost filled, just wondering what the 'sweet spot' would be, how much space in between canopy and my 600w hps light. screen is about 4 feet by 4 feet and heat is not an issue as i have a heft fan sucking over the bulb. thanks for any info advice!
  2. 18" or so
