Hello everyone, fairly new to the board and preparing for my first 3x3 indoor autoflower garden. I purchased 4 QB120’s in 3000k
And 4 QB132’s in 4000k, And I’ll be running them all but at maximum output. My Thoughts were to make a + with the 132 boards and place the 120 boards in the four corners. Now that puts the 4K in the center and 3k on the edges. Is this optimial or should the 3k be centralized and the 4K more to the edges?
Also how do I space these boards out to even out my ppfd for the total footprint of the boards combined? Thanks in advance
