so my seedling just hatched, and I got a new 320w kingbright. How far should I keep my plants away from the light. I have them 17inches away, and dimmed the light a tad

put your hand under the light and move it to a comfotable position and you can have that as the hight from light to plant tops. i have my mars hydro about and the new seedling i have is at 4 inches away the cuttings are at 8 inches

Would 15inches be to far? I thought I heard 15in. Away from the light? I kept my past plants 12 inches away, and that was us a 600w kingled (the actual output is 120w).

What i would do newly hatched seedling under a lamp for around a week 15 watt bulb 4 inches away, it won't burn it just give it some height before tent.
