I have 2 plants in a 4×4 grow tent. One plant is under a 450w led viparspectra and the other plant under a viparspectra p2000 with adjustable dimmer. I just noticed on day 15 after flipp that the p2000 was only at 25% power but both plants are about the same in size. Will this have a significant impact on my quality? Both plants look healthy. Did havi g that other light in the tent might have saved me?
