Decided to start growing last year bought this light and setup a grow area in my basement, was very surprised at how good the weed I grow was. I attributed this to the light. Very easy to use and produces great results, would definitely buy again

I have been growing high quality weed for almost 10 years now and always had great success until 2019. I got bugs that I've never had before and it took me a long time to identify what I had and how serious it was, so in the end, I lost strains that I'd been cloning for 3-4 years. The bug was 'Hemp Russet Mites' and they are prevalent here because it is becoming a hemp capital rapidly. I figured it was time to upgrade my system. I bought a Bloombox from BC Northern lights several years ago. It's been a very good grow system, but as I learned to be a better grower, I've modded my box pretty heavy. I unwired the 400W HPS and wired this baby in. I made little feet so that it sits right on top of the glass inside the bloombox flower chamber light area. So when the bloombox computer turns the lights on, this LED upgrade comes on. The fans come on as normal, so it's continuously cooled by the Bloombox cooling fans. I've been using this for about a month and I love it very much. The growbox is much brighter. It uses about 177 Watts less than the 400W HPS before. So it runs cooler, uses less electricity and the plants love it. There is nothing to change, I just flip the switch from veg to flower (on the Bloombox) and it just changes the timing from 18 hours to 12 hours. The lighting from the growlight does not change between veg and flower. Only the timing (as provided by my growbox). In the enclosed pictures, I took a screenshot on Jan 31 of my two plants that I grew from seed. As you can see by the pics, they grew a lot in one month. This was all with the Spider lights. The last pic shows how well the flowers are doing, both male and female! I decided to cross breed so I hope to have seeds that are Girl Scout Cookies and Chemodo Dragon for my own strain. I feel like this light is so much better than the 400W HPS it replaced. They could really make the package complete if they shipped their lights with a few cool stickers. But yes, if you are looking for a great veg/flower light, this is it!

Works extremely well for the dimensions described! Installation was easy as it comes out of the box set up with two hanging ropes and carabiners -- just hang up both ends and you're done! Raising and lowering is as simple as pulling a cord, and there's a nice loud ratchet in either side that lets you count the "clicks" to ensure you raise each side equally. It didn't blow up my electrical bill and is very bright. My plants are thriving!

I got this light at the beginning of the year to start my summer season crops indoors before the snow melted so I could get a jumpstart on the spring planting season. Its pretty damn nice!!! A little bummed they raised the price once they realized what they had, although they did add an external dimmer on the newest model which I totally wish mine had. The growth and yields are pretty dang nice, and it covers a 4x4 table very well!!! I have ran this against 600HPS in a magnum XXXL hood. ( our old commercial standard for 4x4 tables ) and it holds it own very well. I do wish the boards where a little farther apart and the whole unit was a little larger just an extra .75inches between the boards would have worked and really gave amazing coverage over a 4x4 without hurting anything IMO. Now is this an American Made HLG no no its not, BUT that doesn't mean its not a very good light for the money!!!!! With the new improvements such as the external dimmer dial, and daisy chainable dimmer control so 1 dimmer can run multiple units is a great feature for future upscaling. Now it does tend to run a bit hot to the touch, nothing like a non air-cooled HPS runs but still easily over 100 degrees farenheit. Also the cables and clips provided to hang it do work, but if you have lower ceilings or space is of a premium in your room/tent they can be a bit annoying as they take up about 8-10inches of additional space the way its designed. This is nothing that can't be worked around with a little creative thinking but is still a tad annoying none the less. Quality and yields ( for fragrant/medical flowers ) have been plenty nice, at 400-450watts power draw it tends to produce about 45-50 grams a sq. ft. depending on your style and of course genetics but still on par with running 600 HPS over the same table, same genetics, same everything only thing changed was the light. Long story short, if you need to cover a 4x4 and do it well, the SF-4000 is a solid performer!!!
