SCROG - Questions on screen and light placement.

Discussion in 'Indoor Marijuana Growing' started by Reverend Bud, Oct 1, 2009.

  1. I'm about to start my first grow and I have a few questions about light placement. I'll be using the SCROG method in soil with a 400w HPS light. My screen will be 3 x 4 ft and I'd like to have 6 plants under there. The room is 5 x 6 x 9. I'll be using a carbon filter on a fan to kill the smell before exhausting out a small window.


    How high should the screen be away from the pot?

    How high should the 400w light be away from the top of the screen?

    Do you raise/adjust the height of the light during the grow or do you keep it the same throughout the grow?

    Please help. I've got two growing handbooks but there's not a lot on the SCROG method.

  2. I'm no expert but I was planning on doing a scrog for my next grow before plans changed and from all the reading that I did, the screen should be 8" away from the pot.

    Light distance is the same with traditional growing but here's a chart for ya. Also to get maximum penetration and absorption, I would raise the lights relative to whatever is the closest you can get them to according to the chart.

    One for veg and flower
