The daisy chain feature allows you to connect multiple SF LED lights. That way, you can easily decrease the light intensity of your grow light.įinally, the newest Spider Farmer SF-1000 has a daisy chain function. The newest models have dimmer knobs on the outside. The old lights had a dimming function, but the dimmer was hard to reach because it was inside the driver. The company finally upgraded its LED lights to include that basic feature. Old Spider Farmer models did not have ON/OFF switches. Upgraded: ON/OFF Switch + Dimming And Daisy Chain Function It has a PPF efficacy of around 2.1 μmol/s/Watt. Compared to other models, this is a phenomenal value.įor example, Spider Farmer’s popular competitor is the VIPARSPECTRA Pro Series P1000. That means the PPF efficacy of Spider Farmer SF-1000 is approximately 2.45 μmol/J. The average PPFD of the light at a hanging distance of 12″ is around 531 μmol/m²/s, so its PAR (PPF) output is close to 240 μmol/s. You will hardly notice an increase in your electric bill when running it.īut the question is, how efficiently is this device turning watts into light energy? This grow light packs loads of energy efficiency. Spider Farmer SF-1000 draws around 96 watts of power. This size of the area is because the plants need less light intensity in their vegetative phase. īut the vegetative footprint of the Spider Farmer SF-1000 is 3′ x 3′ (0.9m × 0.9m). Outside that coverage area, it’s challenging to grow heavy-flowering and fruiting plants. It is important to note that the flowering footprint of the Spider Farmer SF-1000 is 2′ × 2′ (0.6m × 0.6m). So, long story short, you can grow anything under Spider Farmer SF-1000. We should mention that plants with the highest demand for light can grow very well with a DLI of around 20 to 30 mol/m²/d. Then the DLI values of Spider Farmer SF-1000 at a distance of 12″ from your plants will be as follows: Let’s assume you’ll turn on the light for an average of 16 hours daily. The DLI is the cumulative amount of PAR reaching your plants every day. We will use them to calculate the Daily Light Integral (DLI) values. ![]() Let’s appreciate these PPFD measurements even more. Those values show that Spider Farmer SF-1000 generates high intensity of useful light. (That is the manufacturer’s recommended hanging height for indoor flowering plants.) Here are our PPFD measurements of the Spider Farmer SF-1000 at a 12″ (30 cm) difference. (Learn more about growing plants with lights.) Here is one way of assessing the PAR of a grow light: Measure its PPFD values at a certain distance using a PPFD light meter. That will help us learn more about its usefulness to plants. We have to test the Spider Farmer SF-1000’s Photosynthetically Active Radiation (PAR) output. Lumens and kelvins are not enough to determine if the generated light intensity is helpful for photosynthesis. The above ratings show the device’s generated light includes almost the full spectrum.īut we need more accurate measurements. The rest generate deep red and infrared light. Most of its LEDs emit light in the 3000K and 5000K spectrum range. Spider Farmer SF-1000 has a light output of around 16500 lumens. The shape is due to having no added built-in equipment, such as cooling fans. Unlike most LED grow lights, Spider Farmer SF-1000 is flat-shaped. Those in the industry know MEAN WELL is an excellent brand of power supplies. MEAN WELL manufactures the device’s drivers, which are fixed to the lamp. Samsung makes its diodes, so they are among the highest-quality LEDs found on the market. The device’s power cords are also well-protected. Its 208 LM301B LEDs are insulated with waterproof material-and so is the board itself. ![]() It holds a good chunk of aluminum, which accounts for most of its weight.Īttached to the aluminum plate is the light panel. The LED grow light feels relatively heavy on the hand. You’ll also find the hanging equipment, a few plant labels, a measuring tape, and a user manual. When you open the package, you’ll find the LED grow light. The company does a beautiful job in this regard. The LED grow light needs some extra protection to prevent damage during shipping. My Spider Farmer SF-1000 arrived well-packaged. But let us first discuss the design for a minute. We are going to review Spider Farmer SF-1000’s performance in this article.
