Fully dimmable and daisy chain ready, the Spider Farmer SE5000 LED Grow Light offers precise control over light output. With easy fingertip adjustment from 10% to 100% power, the Spider Farme SE5000 LED Grow Light is suitable for all stages of growth, from delicate seedlings to resin-rich flowers. The improved dimmer box allows power-savvy cultivators to adjust electricity usage, optimizing efficiency and minimizing wastage.
HLG is American made, so that factors into their slightly higher cost. But HLG actually offers a wider variety of models, including DIY kits that help their prices compete a lot better with similar brands. Spider Farmer only offers three pre-assembled options at the moment. Spider Farmer grow lights are pretty close to HLG in quality. Both grow light series use Samsung diodes and Mean Well drivers. There’s a difference in light spectrum because HLG only uses one white color temperature of 3000K or 4000K where the Spider Farmer grow lights use a mixture.
Q & A
ENERGY- EFFICACY: SE5000 LED grow light has uniquely designed 6 extended LED bars to provide more even canopy coverage, especially to the outer edges of cultivation areas. With 1680 pcs SAMSUNG LM301B diodes, SE5000 Led plant grow lights draw 480 watts with 1333 umol/s, achieving an impressive PPE of 2.75 umol/J. For 4’x4′ Grow Tent, 6 Inch Inline Fan.

The distance between a grow light and plants can vary depending on factors such as light intensity, plant growth stage, and the specific plant species being cultivated. As a general guideline, most manufacturers recommend keeping the grow light between 12 to 36 inches (30 to 90 cm) away from the plant canopy. FULL SPECTRUM & DiMMING DAISY CHAIN】 Full spectrum (660-665nm,2800-3200K,4800-5000K) is perfect for veg to flower, fits for all growth stages. Dimming knob easily to adjust light intensity. If you want American made, go with HLG. They cost more, but they are made in the US and they have continued to improve and are now one of the best grow light manufacturers, period.Quality Driver —dimmable and can be removed from the unit and placed outside your grow tent to keep heat down A smaller fixture emits light from a smaller point in the center of the coverage area. Light traveling to the outside of the coverage area has to go further than light traveling straight down to the center. The Spider Farmer SE5000 LED Grow Light is equipped with a detachable driver, allowing for improved airflow and ventilation by storing it outside the grow area. This feature not only reduces temperatures but also increases headroom within your grow tent, providing maximum space for your plants and minimizing space occupied by bulky equipment. Generally speaking, the minimum PPFD worth required for plant growth is 400μmol/m²/s, and the optimum PPFD value that can be absorbed by plants is 1200μmol/m²/s. Anything beyond that will possibly hurt your plants. And let’s not even get into the fact that wattage has nothing to do with output and is not really a factor you should be considering when deciding on a light, unless the light has a very high wattage with a low output. Then you want to avoid it.
Most HLG lights have white light with added 660 nm deep red or blue, depending on the fixture. The Electric Sky lights feature white light with deep red and IR. The Mars SP and TS lights vary. Some have deep red in addition to white, while others have the same plus IR and UV. You will buy confidently from us since only sell new, official products (no used items or clones). All warranties are new are 100% honored through the respective manufacturer. To sum up, the preferred grow light distance ranges from 12-36 inches, depending on which stage of growth your cannabis is in. Importantly, you should fine-tune the distance to achieve the perfect balance of light intensity and coverage through experimentation and observation. FAQs about How Far Should LED Grow Lights Be from Plants I have written about the COB grow lights here, so I won’t go into any detail about those in this review. The Spider Farmer lights do not use COBs. They use many smaller diodes. DIMMING DAISY CHAIN: The dimming knob lets you change the brightness of the light by 10–100% to accommodate plant growth. Additionally, the daisy chain capability helps growers link up to 30 lights for simultaneous dimming. Highly advised for usage in closets, DWC, hydroponics, grow rooms, home growing ( 4X4 grow tent), etc.What’s new about the 2023 version: New Logo; New dimmer knob, when the knob is turned to 0%, the light will turn off. This 5/5 star review said, “ I love the sf4000 because it has high output with little draw at only 450 W. It outperforms my 600w HPS and runs cooler and uses less electricity. My yields are great with high-quality medicine and I couldn’t be happier.”
The SE series gets a more even coverage area and that is really their main advantage. They are also dimmable and can be daisy chained. To further fine-tune the distance between LED grow lights and plants, it is better to start with small-scale trials. This involves setting up a few plants at varying distances from the lights and observing their response to different light intensities. By measuring plant growth, vigor, and overall health, growers can identify the distance that yields the best results.As mentioned earlier the light is strong enough to flower 5×5 feet. You can see the impressive strength of this light in the image above, where it’s hanging at 22 inches above the canopy. True Wattage: Like HLG fixtures, one of the biggest strengths of the Spider Farmer lights is their form factor. The quantum boards used in the fixtures are large and flat, with LED diodes spread out over the entire surface. Aside from the design, Spider Farmer didn’t previously offer a square 300 watt model designed for 3×3 feet of coverage. Now there’s the SE-3000. They said the SF-2000 was good for 3×3 but I owned that light and I think it was good for 2×4 feet. The SE-5000 offers a 30 watt power jump from the SF-4000 which is also designed for 4×4 feet of coverage. The SE-7000 offers the same 650 watts as the comparable SF-7000. Spider Farmer vs Mars Hydro:
