I just picked this light up on the start of my flower cycle and replaced my mars hydro tsw2000 in my 4x4 tent and there's a massive difference in my plants already

[@xXelitegpXx]

I'm running 2 SF2000s in a 3x3 right now at 65% week 2 veg. 30 inches ,5 plants, 3 gallon pots with roots organics soil. So far so good !

[@xXelitegpXx]

Thanks for the video by the way, so helpful !

[@Justintime2grow]

Thanks for sharing

[@OptimusCrimez]

I just bought 5 spider farmers. All have dimmers and daisy chain.

[@Justintime2grow]

Nice

[@pardonthedank]

Wow... looks like the same little box as on the mars hydro lamps except for a different color. I like the Dimmer/Daisey Chain/On-Off Box.. .adds a nice touch to the lamp.

[@greenghost-xi5jp]

Better components will last longer at near new output. BUT the mars new tech is for sure getting close no doubt. Even viparspectra is getting there and actually i really like the heat sink on the vipar gear better. But bang for buck this is tops for just getting (quality) light on a 4x4. If i was to buy right now and money was not a factor id get the scorpion diablo from hlg but for 85% of us who cant afford that monster (although its clearly the best light out of any kind for photon density) this is by far the next best light. The spread is great for a non bar style and it has the parts and name that you want as far as reputation! 2 of these in a 4x8 and you would rule your area and b the fire man in town. The cross over lightning in a 4x8 would give you 7.5 foot print of 900 par w like 760 at very edges all the way around thats fucking ballin and perfectly even. You wont even notice the difference on your very edges. Besides you want a cpl inches on your ends for air vs having them crammed at the edge. Just a lil over lapping will cause issues w humidity and possibly the most awful problem u can ever get pm!

[@bdog4u2]

I have 2 sf4000s and a 1000w eye hortilux super hps in a 4x10. Hps in the middle with co2. I pulled over 6lbs last run. 25 years of continuous growing

[@Justintime2grow]

That sounds like a great setup. I had amazing results when I was combining led and hps while transitioning from all hps to all led. 👍🏼

[@bdog4u2]

@@Justintime2grow LEDs are definitely king in tents and enclosed areas but in open space i still prefer hps. I run led in all my tents but the old school in me still holds on to my hid. I'm hanging California lightworks UVB t5 now to see what difference it has. 3 on one side none on the other,so we will see.

[@Justintime2grow]

@@bdog4u2 yeah hps sure has quite a spread but that’s also 1100w+ at the wall vs 450 so it should. Two of these sf4000 would crush a single 1100w double ended hps at only 900 watts at the wall.

[@hotboy197988]

I got the SF1000 kit 4 months ago to tryit out I was able to get 1/2 pound off one plant. Do to space I only have room for a 2x4 tent but I didn't want to do there SF2000 because I have plans past that so I've been thinking about just getting the SF4000 and turning it down and I'm glad I went back looking at videos this sold it I did realize you did this in a 2x4 tent when I seen the the video before. Thanks for the time you put into your videos.

[@hotboy197988]

I put this in the spiter farmer 2.5x2.5 tent that comes with the sf1000 kit and it fit. Running about around 18 to 20in at 60%. I had a really good run with the sf 1000 other then my timer got bumped and my flowers started to stretch out. I fixed it but it was a little to late still pull just over half pound from 100w. Im about week 6 or 7 and 2nd week with the SF4000 and wow the buds are harder then anything I've ever had before I used to use hortilux eye 1000w hps flowering and t5 480w and clone CFL. I'm now fully led start to finish it took a moment to get the feeding just right as the plants seen to need more faster then when I had the hps. Also the best stuff I've yet to see

I use the P1500 & the XS1500 by Viparspectra & my Banana Runtz & Divine Gelato x Project 4516 are loving them! My King LED is a 1200w I have covering a 4x4 area just fine, but it's a tent. In my eyes, they're worth it when they're working! But when they go out, the company is a hassle to get ahold of 😅

[@thekidwhogrows]

I know the center on the 1500's is probably only about 950w, & the 1200w King probs peaks at 850w center, but they've been killing it for me

It's optional. You may want to leave them on In winter grows.

Mount them on the outside of the tent?

[@patrickgagne8795]

So I just did a bunch of testing on LEDs getting ready for a 12,000sf grow. I usually run CMH but could not ignore the progress made with LEDs. The numbers this unit puts out is truly incredible and for $600!!! Have to note, they run HOT!!! I placed a small 4" fan pointing down on the drivers and it dropped the heat considerably. This unit beat out a gavita 1700e and growers choice 720 based on my testing. Couldn't believe it

[@mukando11]

how do you connect all of them tho?

[@Breal01]

@@mukando11 daisy chain into a control module. I think you can control up to 100 lights at once now.

[@ryantrumble4582]

suggest buying an aluminum heat sink (under $20) and secure it onto the ballast top with thermal compound (~ $5) and put a fitted muffin fan (120mm) on top of the heat sink to suck out the heat; I was wondering why manufacturers don't offer an extension cable to optionally move the ballast out of a tent scenario.

[@Mr_PNW]

I’ve got mine running along with an 8” AC Infinity system, one clip-on fan up top to move everything around evenly. My ACI and Inkbird controllers are keeping the tent about 72F. Highest i saw was 78F. It is cooling down here in WA State and the tent is in an unheated shop. I’ve even had to get a mini oil-filled radiator that the Inkbird runs. I’ve got 2 of the bottom windows half open pulling in the shop air. I just ordered one of those Govee Bluetooth sensors that sit in the tent and feeds data to the phone. I’m anxious to see how all this data will play out over the next 24/7.

[@805BLAZING]

Just an update. The newest version of the SF2000 does indeed have the separate box with the dimmer, daisy chain, and on/off switch. Id imagine the SF1000 has this same new feature. This feature was a big factor in me choosing the SF2000 instead of any other brand

[@Mr_PNW]

The dimmer also has its own on/off switch on the back of the box which they recommend turning off when not dimming.

Just finished a grow with an SF4000 & SF2000 combo in a 4x4 - absolutely phenomenal results! I highly recommend these lights. My only issue is the heat they radiate esp during the summer months. Personally, I think that they are better suited for a grow-room set-up rather than a tent.

[@Tabooza]

Remove to Drivers from the boarders and put them outside the tent. You just need to splice wires and extend, very simple.

@@Tabooza After this grow and before next summer I just might do that. For once I’m glad for the cool weather here in the PNW.

[@Mr_PNW]

What height and power did you keep your light at for both veg and bloom? The manual is too vague. It says on page 4, Seedling = 24” Veg = 18”-24” Bloom = 12”-18”. Nothing about dimming. I don’t have a meter to check. My clones are about 8-10” tall and I have it at 30” full power in a 5x5x8. The thing is so bright.

Wow dude 2 in a 4x8?!!!!! That’s awesome how are you liking it?!!! Would you change anything?! I’m still debating between 3 Mars SP 3000’s, HLG 650R or 2 SF 4000’s for my 5x5. I’d love to hear what you think!!!!!

[@mmthc303]

Omgcezwho Dude the ladies love it! They’re exploding with growth. The temp is steady at 80-83 degrees with both lights on. I wouldn’t change a thing. I have three 6” clip fans, two 16” wall mount fans and the AC infinity T8 exhaust fan. It’s almost a perfect set up. I just need filters for the tent intakes to keep the air super clean. Bro the 650R is a straight monster. The PAR just blows away the SF4000 and mars hydro. Lol. However, 2 SF4000s is the same price as 1 650R. I feel like you would get better canopy coverage with 2 SF4000s and close to the same PAR as 1 650R.

[@MoonMe00]

Thanks for that info bro I appreciate it👊🏽 I was thinking the same thing about the SF4000 but might be a bit of an awkward fit in a 5x5 unless I put them both facing the corners rather then straight if you get me. What about 3 Mars SP3000 those spectrum look real nice and might be easier to distribute the 3.🤷🏽‍♂️✌🏽👊🏽

[@mmthc303]

Omgcezwho No problem brother! 2 SF4000s would blow up a 5x5 for sure! You might have to turn the dimmer down to 60% 😂 The SP3000s are good lights but at $400 each that would be $1200 plus tax. Two SF4000s or one 650R will put out more PAR than three SP3000s for $100 less. They’re all great lights.

Any chance you could get a proper test going to see if the red coating on the aluminum heat sink on the HLG 300, 550v2 dissipates heat better than without? I own quite a few hlg lights, but i have no way to test the spider farmers, etc. I heard Steven from hlg mention this coating on the GML show and it piqued my interest. Great videos. Thanks! Oh yeah, i noticed the knock offs tend to use 2 drivers instead of one, any idea why they do that?

[@Justintime2grow]

How would that even make sense? It's not adding any mass and it's not reflecting or absorbing light. The larger driver costs more I believe and a lot of them will run the 3000 and 5000 chips on different drivers.

MixJoy gl 2000, meanwell driver, same samsung led's, $140. on Amazon. Two of them are the same as this light for just over half the price. And with the quantum boards separate you can arrange them spaced farther apart to get a better light spread. I have to keep them at about 60% to keep the (flower) par between 600-1000.

[@Justintime2grow]

And if you read the reviews someone said they got 2 and neither of them were the wattage they said and both were different wattage even. A lot of companies also sell fake diodes. I only trust companies I know. Also the new sf4000 has the diodes spaced differently to improve spread. You also don’t own a par meter if you’re that cheap so your fake ppfd rating is useless as well. Mix joy also uses ELG drivers not XLG drivers. Not all meanwell are made the same. They cut corners. That’s why their power is less too. Xlg are always at max power no matter the voltage where elg can be variable depending on exact voltage. If you want to save some money go ahead but it’s not the same thing.

Better to use two SF2000 daisy chained in a 5x5. More even light distribution than the SF4000. I certainly wouldn’t call them “Cheap Amazon Grow Lights”. They’re one of the top quality lights available, but not for a grower on a budget. Personally, two SF2000 or one S4000 in a 4x4 will be more than adequate, but I use a Lumatek 600 Pro in my 5x5 GGT. More than efficient for an XL Wilma Atami drip feed system with either 16 6l or 9 11l pots in a 115cm sq unit. Ideal for SOG or SCROG growing.

spider farmer SF4000 is considered as cheap amazon light? :D it's well reputable brand for it's quantum boards quality and price

[@Justintime2grow]

They're a "cheap" version of a HLG. One of the cheapest you can get with such good components. So yeah, cheap amazon light category.

I have 2 newer sf2000 in my 4x4. I run a 6" fan on the drivers. My tent runs 3-4 degrees Fahrenheit cooler. Plants also love em. I.have to feed more often too compared to my old viparspectra 600s. I'll never go back to blurple!

How hot does it get in your tent with those 2 lights. I was gonna get a sf4000

[@KeepinYouUp07]

@@shroomsopenminds3623 depends on the temperature of the room it's in & your air flow. Mine is generally no hotter than 84 average around 79

I didn’t know the sf-4000 for $425 on Amazon was a cheap light ha. How about the $600 ks 5000 by viparspectra is that cheap too ? How expensive do these light get 2000 ha

About 1400 for top end. So yes this is considered "cheaper".

Hey, Justin or anyone, I'm running an ac unit in my tent. my question is how close can the spider farmer 4000 be before worrying about heat stress.

Probably around 4" but youll see light stress first.

You remember the original blurple Spiderfarmer when the Company still went by Mehezi and were fire hazards. Sure didn't use quality components then. Mixjoy has more chips plus UV and IR and app controlled as well as 150$ cheaper. Get a HLG 600 R/SPEC. Its bout 50$ more than the overpriced Spiderfarmer..

[@jonyoakem6882]

Would you use the dimmer during veg and or flower and why

[@johnedmunds1380]

If you have height problems

[@forsakenoutcast]

The kit I’m looking at comes with a 5x5 tent, and in the first page on the manual it says max 5x5. In your opinion will a 5x5 tent be alright for this light?, might have some serious drop off on the edges I guess?.

[@elizabethwebster3327]

Spider Farmer states that it covers 6x6 veg and 5x5 flower. I have a 5x5 tent tent and just received mine yesterday. So far so good.

[@Mr_PNW]

@@elizabethwebster3327 I’ve had mine for 2 weeks. What height and power is yours at for veg? The thing is bright and w/o a meter I went with 30” full power.

[@elizabethwebster3327]

First few days it was at 20% at 4 feet because I'd read somewhere starting at 4 feet is a good start if you're nervous about upgrading and have fresh seedlings. I didnt want to bleCh my seedlings. I now have mine at 30% sitting 24" .. will probably increase the intensity as it grows then drop off once it reaches closer to harvesting when I do 12/12 intervals. My plants are about a month old now.. it's my first grow, so it's been trial and error.. but so far nothing looks concerning based on what to watch out for. Tried it on full blast for 4 hours and came back to my tent at 36c and 40% RH so it puts out ridiculous heat in a 5x5.. I wouldnt put it full unless you have a crazy good flow to disperse heat output.

[@Mr_PNW]

@@elizabethwebster3327 This is my first grow too. It’s cool here in the PNW and I picked up my clones from the grower the last days of Sep. Looking at my records the grower cut the clones 8/25, so that makes the plants almost 2 months old. The plants went into the 5x5x8 GGT Oct 1st and were under an LEDTonic Z5 light (blue setting) for the first week until I figured out and settled on the SF4000. Originally I had the Z5 24” above the tiny plants and hung the 4000 at 5’ full power just because it’s been so cold, it was a heater for the tent. Last week I got a mini oil-filled radiator so I’m not concern with heat anymore. My temp is set to range 68-76F and it’s maintaining 72F. My AC Infinity T8 has handled keeping it at the right temp, that things a power house. They have really come to life the past 10 days with height and many new branches And leaves so I removed the Z5 and lowered the 4000 to 30” full power. I came here trying to figure out the best height and brightness which has been nerve racking. Now I’m concerned it’s either to close or too bright at 30”. I want to flood the tent with light so every branch and leaf get plenty. With heat under control it would be nice to have a chart of weeks with height and dimmer%. The manual says nothing about dimming accept as a daisy chain setup. It sucks.
