This is what my grow buddy uses. It does great compared to my blurple cheaper lights, being disabled it was my only option unfortunately. We have done close to the same exact grow, major differences being the lights. No matter what I did he always seemed to have way more density then mine. I can only think it's the light difference. I would love more then anything to grow an experience your lighting for myself in my own medicine. Definitely can see it in action first hand and it is awesomeness

So I run a perpetual harvest as a caregiver and we harvest every week. We are currently using HPS in our flowering rooms and dual spectrum in our veg T fives over clones. I purchased a 10 x 10 tent and to SF 4000 spider farmer lights. So far I am pretty happy I'm only going to run them on half the 10th feeling that I need to have another two to be able to cover the other half of the tent properly. I only gave it four stars because when I'm boxing the first package both of my Meanwell ballasts I had been knocked off the back of the board and had to be re-screwed back on but I believe that had more to do with shipping then spider farmer as their packaging was very nice. The lights are significantly brighter than I thought they would be and I am a little skeptical on ... MoreSo I run a perpetual harvest as a caregiver and we harvest every week.

The lights are significantly brighter than I thought they would be and I am a little skeptical on how many plants you can put under one of these lights so I will be placing one plant under one light and five plants under the other as soon as I can afford it I will be ordering two more lights really hoping to be able to replace my large room with these LEDs when it's all said and done. I am also looking forward to ordering the control board I currently use something similar with my HPS system and nanolux

Ran 1000watt hps for almost 10 years. Wanted to make the switch to led and I did plenty of research before I made a purchase. Lots of more expensive options out there, however I can't justify dropping a grand on a light..at least not then. Through my searches and comparing one light to another..I kept coming back to spider farmer. Pulled the trigger and picked up a sf-4000 to get my feet wet. Best decision I made when it comes to illumination. Tons of quality light.. doesn't run that warm and the spectrum is dialed in! I have another brands light together with the sf-4000 as I felt I needed a little more power in my space. Didn't set out to do a side by side comparison..but the flower under the spider farmer is noticably bigger and resin production is superior. The ... MoreRan 1000watt hps for almost 10 years.

The quality of the build is superior also.. quality materials and fit and finish. Top notch components..put together well..at an affordable price..what's not to like? In the future.. spider farmer will be the first light I look for.

This light has been amazing for me my last two grows and does great for an indoor grower like myself. Its very good on the energy bill and the plate the lights sits on produces the perfect amount of heat to keep my tent at the perfect temperatures needed for my plants. I love the dimmer attachment; it saves me time knowing I dont have to adjust it through the drivers. Even though the light up front is a nice chunk of green backs; its worth every penny. After doing a good amount of research and seeing some fellow growers using this light I knew it was the best product for the type of growing I do. Energy saving, great light spectrum, and makes my plants happy. If you run it for 24 or 12 hours a day you will be happy with what this light can do.

I used the SF4000 for my last grow, with fantastic results. It was a perfect size for my 4x4, and gave ample coverage for the entire tent. My harvest was up from the last lights I used. I had one plant and harvested over 1 lb, which is fantastic because the plant was not near as big as I could have grown it. The buds were nice and tight, which is to be expected from a quality light.This light puts off a little heat, but not much when compared to other brands. I had no heat problems at all. It was easy to assemble and hang in my grow tent, and took me less than 10 minutes from unboxing to hanging in the tent. I am very happy with this light and would recommend it to anyone that is looking for a quality light at an affordable price.

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 4x4 was bursting at the seams. I didnt hesitate to get myself an sf2000 for my veg tent. And also built a full 8x8 room instead of the box. Recommended highly!

This light has made me flowers that are 2x as dense and at the very least 15% bigger than before. Looking at 2 sf-4000's making the tent feel like summer, which actually helped with VPD! Vapor pressure deficit is humidity to temperarure ratio for plants to perform at their maximum potential. My plants love it warm but not over 90 and these lights kept it around 80-85 when they were on. All I needed to do is push humidity in and I got amazing results. Most LED's are either too hot or too cool - these are right in the center for that perfect environment! I'm an organic grower and I found there to be better results inside my tent then outside. I had very little sun light this year so Im bringing everything indoors for the winter! Thanks for the amazing lights and my ... MoreThis light has made me flowers that are 2x as dense and at the very least 15% bigger than before.

Used a friend of mines blurple for few weeks prior. First time grower. Within a week I have surpassed his(my plants were noticeably smaller than his). Its as if it grows by the day noticeably. Defoliated on Monday, within four days it's as if I didn't. I can't believe the difference a light makes. They're so lush and happy now. Can't wait to see what flowering will do. Im only at 60% brightness now in Veg. Best bang for the buck hands down. My friend is jealous by the way. I have his clones moving faster than hjm.

Had one light…..now i have four. They are well worth the money, awesome results. Highly recommend. The shipping was faster than expected and the products i ordered were all in perfect condition. These guys have everything i ever need plus lots of great stuff to think about for my future grows. Always start here when i look for stuff, thanks to all staff and supporting team great job all around.
