Check the following fit chart to find how many lights you need for your grow tent.For Bigger Growing Space, SF4000 / SF7000 / SE5000 / SE7000 will be more suitable.
LOWER RUNNING COSTS & HIGHER-QUALITY YIELDS: SPIDER FARMER LED Grow Lights utilize the latest in high-yielding LEDs technology today-Samsung LM301B diodes, high Energy Efficiency with 2.7 umol/J, create better canopy light penetration. SF4000 only consumes 450w, running 50% less power than the HPS or Blurple lamps, and still was 50% more harvest. The veg footprint is 5 x 5 ft, Flowering footprint is 4 x 4 ft.
CUSTOMIZED DIMMING DESIGN: Upgraded SF series growing lights have a dimming knob and light switch. A single light can be adjusted to the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large areas of indoor growing and commercial planting.
IDEAL FOR ALL GROWTH STAGES: Excellent full-spectrum- white, blue, red, and IR (3000K, 5000K, 660nm, and IR 760nm). 3000K diodes providing more reddish light and 5000K providing more blueish. The 660nm red and IR light is especially useful during bloom, where it speeds up flowering time and boosts yields. Turn your seeds into your own supply. And the light looks fairly natural, so it’s good for accurately monitoring plant health.

Used this product since I started my medical grow. Compared to other quantum boards that I’ve had. This one is an absolute beast. I only need about 60% light it gives with the dimmer for my babies then I turn it up 100 during bloom and flower because 100 during veg is TOO much. Which is a good thing. Never had any problems with the light. It is big and heavy so if you want to get I recommend you have someone to help you put it up. Don’t want to drop it ! It might seam steep if a price. But my products come out better than other products who’s tent doesn’t equip the s4000 just won’t get as much light.
I grabbed 2 sf4000s. I’m very happy with results so far. Excellent quality and performance for the buck. I would for sure recommend anyone buy these. I will be buying more.
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 electric. My yields are great with high-quality medicine and I couldn’t be happier.
When I purchased this light I was using a 400w HPS and a 400W mH side by side in a 4x4x6 box i built with plywood. Had 4 seedlings going in my own soil recipe. They had been under this light for almost 4 weeks when i received my SF4000. I expected good things from this light, but was blown away after a week i had 3x the growth rate and they were ready for flower. The next flowering cycle i did i had to remove the top of my box and hang the light from the ceiling, my 4×4 was bursting at the seams. I didnt hesitate to get myself an sf2000 for my veg tent. And also built a full 8×8 room instead of the box. Recommended highly!
I love my sf4000. It outperforms my 600w hps and has a high output with low draw at only 450 Watts. With less electricity and lower Heat it’s an easy pick over h p s. I get high quality meds and great yields, I couldn’t be happier.
Could not be happier with the professionalism and fast service of http://www.spider-farmer.com. Originally ordered the the SF-4000 LED grow light from a 3rd party re-seller. Didnt get an order confirmation or tracking # for over a week. Cancelled the order, and bought directly from Spider Farmer. They had the light on my doorstep in 3 days. Solid packaging… Proper light.. Thank You Spider Farmer.!
I have an sf4000 and an sf2000. I love both of the lights they are great for personal at home grows. Easy on the electric bill and still produce big fat frosty buds. I have many lights from many brands but spider farmer is the only one I have bought more than one of. Best bang for your buck I believe!
I had the opportunity to use the SF4000
I highly recommend this light for indoor grows
Heat was never a issue
Light coverage was everything expected
Great and easy to use
Highly recommend!!!
