Fluorescent and LED lights have a lower heat signature, so they can be placed 12 and 6 inches over plants respectively. How much heat does a 1000 Watt HPS produce? taking the inverse square law into account if your 17" away the strength in lighting would be more even from top to bottom. A 600W HPS light should be kept about 16″ (40 cm) away from the tops of your plants This grower didn’t keep moving the 600W HPS light up as plants got taller, and some colas on the left plant got within 12″ (30 cm) of the bulb.

Once Veg kicks in, it is safe to say lowering gradually to 18 inches does the trick. HPS or high pressure sodium bulb are efficient and very bright light sources. We provide the information and the links as a representative example of a 600w HPS light for comparison. For quick approximations, it is enough to remember that doubling the distance reduces illumination to one quarter; or similarly, to halve the illumination increase the distance by a factor of 1.4 (the square root of 2), and to double illumination, reduce the distance to 0.7 (square root of 1/2). Subsequently, question is, how far should a 400w HPS be from plants? Sixteen plants that are grown under a 600-watt HPS lamp could produce about 37.5 grams or 1.3 oz of marijuana per plant.

If you light your plants by a narrow beam from the top you only light the top canopy of leafs. Hanging Height: 60cm (24in) Flowering Coverage Approx: 120 x 120cm (48in x 48in) Metal Halides/HPS Lights Hey guys, my sprouts are almost two weeks from sprout. HID lighting systems include metal halide (MH) and high pressure sodium (HPS). How many plants can you have under 1000w?

Since you have a light mover your plants are a lot less likely to get light burn, and you can keep your lights closer than normal. 640W (incl. Go the Distance HPS lights should not be placed inches from the plants, as you would place fluorescent lights; you should set HPS lamps higher, generally between 5 and 8 feet from the plants.

When the illuminant is not a point source, the inverse square rule is often still a useful approximation; when the size of the light source is less than one-fifth of the distance to the subject, the calculation error is less than 1%.
