The SF-7000 also includes infrared and ultraviolet LED diodes which are beneficial for cannabis plants. These extra diodes are not commonly included on many grow lights, adding extra value to the SF-7000. Folding Light Board:

The spectrum included with Spider Farmer lights is exactly what you want and need for growing cannabis, or other types of plants. It consists of 3000K white, 5000K white, 660nm Red, and 760nm Infrared diodes. All together they make up a nice full spectrum white light. Dimming and Daisy Chain 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: If you want to learn about how light intensity affects cannabis plants, read my full article here. True Wattage: I make about 1 might&control setup every few weeks for friends and family. Have been for the last year and half with LEDs. Strip and boards. Not just myself but many people running these same lights are achieving 2gpw (never even got close with hps/mh) Mars is what new growers buy when they have no idea what to buy. They have a history of false advertising and sub par quality. I would never buy one after using the freebies my friends passed on over the years. Of course @DankVader75 is going to go Mars every time, it was free. Further He uses a burple as comparison, which is arguably the worst led lights you can grow with (old tech, poor spectrum, poor internals and components). Please don’t take this the wrong way @DankVader75 as I’m sure you are happy with your new light, I just have used them and hate them and hate seeing new growers get caught up in the garbage. I could care less what light some one else uses, they should just know @MarsHydroLED has a poor history, has a history of poorly made led lighting products, and has been purposely misleading growers for years with their false statements and claims. Maybe they have improved, but I’ll be sure to share my thoughts every time I see some one ask about their product.

So are the Epistar LEDs any good compared to Samsung? Yes definitely. They produce a similar light intensity to Samsung, and a similar efficiency. Epistar is a leading LED manufacturer, they just happen to be sell LEDs at a lower price than Samsung. The Spider Farmer SF-7000 is the highest powered Spider Farmer grow light available. It uses 1,716 LEDs at up to 650 watts of power to flower up to 5×5 feet, and up to 6×6 feet for vegetative phase growth. The SF-7000 uses 650 watts from the outlet, despite the 7000 number in the name. Compared to other similar LED grow lights for 5×5 feet, the SF-7000 has the same wattage as the HLG 650R, and slightly more than the HLG 600, both of those grow lights cover a similar sized area. The power efficiency is also similar to other 5×5 foot coverage grow lights.

The light intensity is directly correlated to the growth of your plants. If you’re tempted to buy a less expensive model be sure to keep that in mind. 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. These grow lights are more energy efficient than traditional LED grow lights. That’s partially due to the fact they don’t use cooling fans. Another reason is the LEDs they used in these designs are newer versions of diodes compared to grow lights that were designed years earlier but are still for sale today. One owner said the node spacing on their plants is like something out of science fiction. The nodes are super close and it’s amazing to see. Believe it or not this person said they like the way their plants grow under the SF 1000 more than the way they grow under his 600 watt HPS light.During the winter months when your room is colder, the moderate heat coming from the Spider Farmer grow light may help maintain temperatures in your grow space. But during the summer months you may choose to use a space fan or take other measures to lower the temperature of your grow tent. Uniform Light Coverage: Eichhorn Bilodeau, Samuel et al. “An Update On Plant Photobiology And Implications For Cannabis Production”. Frontiers In Plant Science, vol 10, 2019. Frontiers Media SA, doi:10.3389/fpls.2019.00296. Accessed 14 Oct 2019. Based on the numbers Spider Farmer provides, The SF 1000 hanging from 18″ is enough to hit that moderate yield threshold across a 2×2 foot space:

Mine came with a handy measuring tape so you can accurately measure the distance between your light and your plants. It also comes with a hanging kit. There is an 8 foot power cord attached to the driver, which is detachable from the grow light so you can keep the driver outside your grow tent to keep temperatures down. Regardless of whether you’re in the market for a low cost light, or a professional grade light for a larger space, Spider Farmer has a nice lineup from the affordable SF 1000 to the serious SF 4000. The main difference is the brand name premium on Samsung LEDs, which I don’t think justifies a more expensive light. There’s also a negligible difference in LED spectrum color temperature.The bar design spreads the light more evenly across the canopy compared to the more compact square design seen on grow lights like the SF series. Don’t get me wrong, the SF Series will perform great in your grow tent, the Spider Farmer SE Series are just another of many options available to home growers. Spider Farmer’s 2.9 micromoles per Joule is at the very high end of efficiency compared to most other grow lights that typically fall between 1.5 and 2.4 uMol/Joule. Fanless design The Spider Farmer SF-2000 is priced more attractive than the HLG 350R, but it also uses less power (200 watts vs 330 watts) and covers less grow space. The SF-2000 is best suited for 2×4 feet, while the HLG 350R will flower 3×5 feet, and veg slightly larger. Spider Farmer vs Any Other Grow Light: For that difference, the Mars Hydro TS Series grow lights are priced lower than Spider Farmer. Spider Farmer vs HLG Grow Lights: There are four sizes of Spider Farmer grow light available – The SF-1000 which flowers 2×2 feet, the SF-2000 which flowers 2×4 feet, the SF-4000 which flowers 4×4 feet, and the SF-7000 which flowers 5×5 feet. You can read the specifics about each model below, as well as how they compare to other brands like Mars Hydro.
