When you first introduce plants to your grow space, if using a 600W light, you need to keep them at least 3 - 4 feet away from your plants to begin with, just while your plants climatise to the heat.
Subsequently, one may also ask, how far away should a 600 watt light be from plants?
In general, with HID (High Intensity Discharge) lighting—including MH (Metal Halide) and HPS (High-Pressure Sodium)—individual 1000-watt lights should be kept 24 – 30 inches from the canopy; 600-watt lights should be 18 – 24 inches away; and 400-watt lights can be as close as 12 – 18 inches from plant tops.
What happens if my grow light is to close to my plants?
On the flip side you can also cause problems to your plants if the grow light is to close. The obvious problems occur with CFL and HPS lights because of the heat they emit they can easily burn the tops of your plants.
Many growers also report strange or stunted growth when the light source is placed to close to plant.
What happens if my grow light is too far away from my plants?
If you put your grow light too far away from your plants you can cause much damage. The biggest problem of all is stretching, this is when your plant puts extra effort into growing taller so that it can be nearer the light source.
Because they put all their energy into getting closer to the light they don’t put as much energy into producing yields, this will lower your yields by as much as 30%, let me repeat, you could be getting 30% less yields simply because you positioned your grow light to far away!
