Spider Farmer SF1000 LED Grow Light with Samsung LM301B Daisy Chain Dimmable Full Spectrum Grow Lights for Indoor Plants Veg Flower Growing Lamps Board 3x3 ft Coverage 100W New Diode Layout

Product Information

As mentioned above, I would go with Mars or Spider Farmer and choose whichever has fixtures that best cover the size of my grow space. All else being equal, I would prefer the Samsung chips in the SF lights, over the Epistar chips in the Mars lights. On the downside, the SF600 does not have a dimmer knob, nor is it water resistant. These features are becoming more common in affordable LED grow lights, so it’s a bit disappointing. The design is also fairly easy to bend, as the light panel is mounted directly to a thin metal light reflector hood. This 5’X5′ grow tent is spacious enough to accommodate 9-12 full-size plants throughout their entire growth cycle, from seedling to harvest

Surpassing the capabilities of both the Samsung LM301H and LM301B LEDs, these EVO LEDs redefine plant growth enhancement. With superior light quality and an increased light output per LED, they harness a more potent blue spectrum, all while achieving a level of efficiency unattainable by non-EVO LEDs. Veg footprint is 3 x 3 ft, Flowering footprint is 2 x 2 ft. NEW DIODE LAYOUT & DIMMING DESIGN: Newest upgraded SF1000 growing lights, the diodes arrangement gathered at the edge makes the PPFD more uniform, absorb light better, produce higher yields. The dimming knob be adjusted the light intensity at liberty. Multi-light Connection with unified dimming especially beneficial for large area of indoor growing and commercial planting.

This is contrary to LED grow lights with fans, which produce more noise during operation. They also need that extra juice to keep the fans running. The long, thin design of the SF600 is another positive, especially for those of us who primarily need lights to start seedlings indoors. For pepper and tomato growers, this light will be perfect for getting your plants off to a strong start before moving outdoors. But it does not mean your grow room is any cooler. The diodes and drivers still generate the same amount of heat and that heat will warm your grow room in the same way. 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.

Spider Farmer SF fixtures have a mix of 3000K and 5000K white diodes, with additional 660 nm deep red and 760 nm IR diodes.From a distance the Spider Farmer SF1000 may look like many other LED Grow Light fixture. But take a closer look & you'll notice that these are all premium materials. No cheap & cheerful plastic here. The Spider Farmer SF1000 is built with quality as paramount and the SF1000 is built to last. The aluminum heat sink has several unique advantages compared to grow lights with cooling fans attached. The energy consumption of SF1000 is important to consider for those looking to keep their electric bills low and for those that are environmentally conscious. (Um, hi!) Dimming Capability: Our lights feature a dimming knob for adjustable light intensity, making them ideal for large indoor growing areas and commercial planting. SUNLIGHT SPECTRUM: Full spectrum led grow lighting 660-665nm,3000K,5000K, and IR light, ideal for all growth stages (germination, clones or cuttings, mothers, vegetative, and flowering applications), turn your seeds into your own supply, produce beautiful high yielding plants.
