GMO Bomb Pheno hunt

I cooked up some soil with 1/3 sphagnum peatmoss 1/3 worm castings and 1/3 perlite. I also added Gaia Green 4-4-4 and some kelp from down to earth. In the pictures you can see from the center of the light I have a few probes hanging at canopy level as well as a 24 inch long string. The string has white markings on it for every 6 inches. I use that to approximate the lamp to plant distance.
