This light is just what I wanted to fill my 5x5 the spectrum is incredible! I post quite a few videos a week with my plants and there progress and people ask me what is that and I tell them it’s the sonic farm alpha 6 and I tell them to look into buying your lights I will grow with you guys from here on out !!

I been using these lites about a year,and not only do I love there lite but also there customer service is top notch ,all my plants are healthy and happy. But I will say LEDs are alot different than hps.

My wife and I bought the sf4000 for our first indoor grow to extend our vegetable growing season. We got the light last wednesday, today is the 5th day and there is a huge difference already! We are growing Kajari melons in a 4x4 tent. If you are wanting a high quality light from a great brand, then look no further. I spent hours reading reviews and contacting growers who posted reviews using the "other" brands. I can tell you one thing, the owner of this company does not have to bribe me with promises of huge discounts or being sponsored with free lights for a great review. The product speaks for itself! In fact, we plan on buying another sf4000 soon to grow lettuce/herbs in a different 4x4 tent.
Oh, I almost forgot, an American small business with an 5 year warranty to top it all off!

This is an extremely well made light and very heavy. Awesome light

I got this light on sale for $300 and decided I had to have it to replace three cheap 100w LED units. This thing provides much better light coverage than multiple smaller lights on top of being better quality diodes. I run the same strain and this run is my first flowering with this light and my plants look absolutely amazing and the nugs are much bigger already compared to where they were this time with the last lights. Their listed PAR maps match my readings as well, so they aren't exaggerating their performance.
If you're ready to pull over a pound a run with minimal wattage, this is the light for you.

First I can't believe how quickly my order was processed and shipped!!! Thanks
Second the light is very strong and is doing a great job 👍

This is my third SF4000 and I can't recommend them enough. I'm running 2 in a 4x8 and 1 in my 4x4. Rock solid nugs for sure!!! They're fairly cheap, perform much better than my old Mars Hydro and Spider Farmer, they're US based, 5 year warranty and my girls love them. You can use discount code "darrinv8" to save an additional 5%, free shipping and no tax. I can't recommend Reuben and Sonofarm enough, seriously an amazing company with amazing lights.

Just ordered another one for my 4x4 as I already have 2 in a 4x8. These are amazing lights, fairly cheap and have a great 5 year warranty. My buds are rock solid now ❤️ You can even use discount code, "darrinv8" to save an additional 5%, get free shipping and pay no tax. Can't recommend
Sonofarm enough!!

So i just bought a PRO 1000 for a 2x2 tent and its working awesome, the plants are loving it! it arrived fast, the dimmer works great, and instalation was really simple. Im coming back for more thats for sure! Great light for great value!

I don’t grow your typical things with this light, I actually do citrus trees in the north. These lights are just phenomenal. Been using them for 2 years now. Just upgraded to two large lights. Will never buy anything else.

this is a great light had to buy a second light to run in my 4x4 tent.You are now my go to for lighting

This light is built well and works well. Arrived 4 days early 👍🏻

I'm currently running my 2nd SF4000 in my 4x8 and it's a tank. The ladies seriously love it. No more larfy buds lol. I previously ran Mars Hydro and Spider Farmer and this Sonofarm light blows them outta the water. I also like that they're a US based company as dealing with international companies regarding warranty issues is like pulling teeth and the 5 year warranty is huge. Give these guys a shot, I'm sure glad I did.

This is my 2nd light I haven't hung yet but I have plugged in only complaint is my coupon code would not go thur and when I asked thur chat I was totally ignored but when I said my order wouldn't go thur they replied very fast. And this was before they went on vacation and gave out code for 10%.
