The following countries need to ship from China, the buyer needs to bear the customs clearance. Please pay attention. I’m a newer at growing “tomatoes” and had my tent plus ventilation working fine. Anyhow my plants were starting to not respond very well to the 34 watt + 13.5 watt led I had from Home-Depot. I did a lot of looking around and research and landed on this spider farmer. Proper ventilation eliminates odors and ensures a healthy growing environment. Carbon filters and fans come in handy when you want to enjoy your garden’s scent without others smelling it. For example, Spider Farmer’s popular competitor is the VIPARSPECTRA Pro Series P1000. It has a PPF efficacy of around 2.1 μmol/s/Watt. Upgraded: ON/OFF Switch + Dimming And Daisy Chain Function

BETTER LIGHT TRANSMISSION: The SF1000D LED grow light uses Samsung diodes – the highest light output LEDs available – to provide a powerful light output and uniform canopy penetration, resulting in a maximum yield higher than other LED grow lights. The unit has 384 individual LEDs mounted on a thin metal hood shield. It is a full spectrum light, with output across the PAR (photosynthetically active radiation) spectrum. In other words, the light looks like natural, white light, and won’t bother your eyes.Many gardeners still believe the heat sink of Spider Farmer SF-1000 is not as powerful as other grow lights—such as Mars Hydro TS 1000.

I’d base my decision on which company has fixtures that best fill your grow space, with the edge going toward SF, due to the Samsung diodes. But UV is really only useful for the last few weeks of flowering (more on the effects of UV here), so I always say it makes more sense to just get fluorescent UV tubes if you want to add ultraviolet light to your grow. Dimming Capability: Our lights feature a dimming knob for adjustable light intensity, making them ideal for large indoor growing areas and commercial planting. Another benefit of the Samsung and Spider Farmer driver combination is a very low heat output. It is so low that the fixture is passively cooled. It has no fans.

Q & A

This light is also full spectrum, meaning that there is coverage across the PAR range. There are 4 types of diodes for maximum growth: 3000K, 5000K, 660nm, and 760nm. I find that the SF1000 emits a “warmer” light than other full spectrum grow lights, perhaps due to more red diodes. SF1000 Hanging Height and Coverage Area The SF1000 LED grow lights from Spider Farmer offer several top features for efficient plant growth and higher-quality yields: For some of you this part might make no sense at all to you but it is one of the most important parts and is why some led grow lights cost more then others! Make sure you

One of the top features of this SF LED light is its low power consumption. That’s all thanks to its LEDs and Aluminum as a heat sink. The light only consumes around 96 watts with a PPF efficacy rate of around 2.45 μmol/s/Watt. Disclaimer: Spider Farmer provided these grow lights free of charge for testing and review purposes. Here are our PPFD measurements of the Spider Farmer SF-1000 at a 12″ (30 cm) difference. (That is the manufacturer’s recommended hanging height for indoor flowering plants.) DIMMING DESIGN: 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.

Spider Farmer Review: Final Verdict

Spider Farmer is committed to providing the best prices online for all our products. When you shop with us, rest assured that you are receiving the best online prices. We advise you not to pay much attention to that measurement. It’s irrelevant and a bit exaggerated.

IDEAL SPECTRUM FOR PLANT GROWTH: Excellent full spectrum – white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm). 3000K provides more red light and 5000K provides more blue light. 660nm red and IR light is especially useful during flowering, where it speeds up flowering time and improves yield. The SF1000 comes with a dimmer box, a water resistant coating over the diodes, easy-to-use ratchets and hanging ropes, and a useful setup booklet. The dimmer makes it easy to dial in the perfect amount of power, while the water resistant coating offers peace of mind. Spider Farmer SF1000 grow light above pepper plants. This is a great entry level light so as expected the coverage area is on the smaller size of about 2×2 and I would recommend this light for 1 medium sized plant. If you let the plant get to large it will be outside the main coverage area. Buds located out side the main coverage area will not be as dense or frosty as the ones under the main light coverage area. Are Spider Farmer Lights Any Good? 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.I’ll take a look at each light’s power consumption, efficiency, recommended hanging height, and coverage area. Then, we’ll decide which may be more suitable for your particular growing needs. Let’s get started!
