@uncle dunk I didn't say not to use CO2. I was sharing a tip for estimating the PPF requirements for growers who aren't using CO2. If a grower is using CO2, then the plants would be able to utilize more photons and the PPF / PPFD / DLI levels can be higher.
@@jonbgreen6916 As shown in this video, the light requires a certain amount of vertical height for optimal coverage. This makes it great for commercial growing in an open warehouse style layout. The primary situation where bar lights excel would be for tight vertical clearances like racks. Otherwise, there's really no reason to stay away from this type of light.
I bought the sf 4000 to grow herbs and it's doing great.i have a fan constantly blowing on the top power supplies to keep them really cool and hopefully make it last alot longer.i bought it because of your review of it.thanks
I’ve purchased 2 SF2000’s (both from your links) and I am very happy with them! So easy to use and my plants have been phenomenal-can’t ask for more than that. Thanks!
Hey gracien, just want to say goodluck to you. My community and myself included just suffered a very bad harvest failure, it have been raining non stop here and it caused a lot of flooding that damaged a lot of plants and the one that survive dies from fungal or bacterial infection, it's especially bad considering the state of the world right now so I'm wishing nothing that happened here ever happen to you
Hello AlboPepper, to be honest, I am amazed by your reviews. I searched a lot for different lamps reviews and so on. But no one delivered like you did. I started to check out your other videos too and wow ... they are so great. I am so happy that I found you. I studied physics. I am German. I need proper reviews with details, going into the specs. You are the one delivering it. You are outstanding and awesome.
i agree 100%. i even bought one for $400 and it didnt compare to the sf4000 side by side so that mixjoy without dimmer went back and got me another sf. Took me awhile to be convinced about leds but after the results of 2 sf4000's runs I am a believer.
@@brianfyffe8204 the appropriate question would be, what is your square footage. All plants require different amounts of light to flourish. Example, lettuce versus "tomatos".
I just received my SF4000 today, glad I found your video today as I was setting it up. I am a little perplexed as to setting the distance though. My setup is a 4x4 grow tent. I have several items in there but more importantly I have a chili plant in hydro that’s flowering but wondering as too optimal distance and dimmer setting. I currently have it set to about 18in per the manual. Eventually I will move the other items out once last freeze is safely gone for my zone.
I have had an older model sf 4000 (dimmer under the drivers) so I’ve used it only at full power for a year now. I grow auto flowers and I’ve come to find out that using it as I have is just fine as long as it is never closer than 20” at any point in the grow cycle. That said, I highly recommend Spider Farmer in general, especially for the price point.
Thank you for your wonderful Content as It is so helpful to the new grower. I just purchased a SF 2000 spider farmer light as well as a 2 x 4 grow tent for auto flowers. Hoping you can share with me your favorite light hanging height and intensity on the dimmer knob for the seedling, veg, and flower stages of the plant.
Thanks to you and migro I think there's a lot off people that ain't gettripped off thanks to you both,I sold mh hps but now young folks want leds mars spider vivosun hlg bloomplus I like the mars if you can get it cheap enough
I am just about to get back in the swing of things and am about to get an sf 1000 wt led. Awesome info. Just discovered you as well. Subscribed and lovin your output. Thanks, man.
Great figures breakdown, very informative, easy to understand and super helpful! Abs love it, lots of really valuable info, excellent for newbies, keep doing more! 👌
My SF4000 only covered an actual 3'x3' area in flower, with the center being way too intense. The outlying 1'x1' area of the tent was a total waste. I replaced it with a Mars Hydro FC4500 that actually covered the 4'x4' and the difference in yield was impressive in addition to being a really good light. They nailed this design and I hope you can test and review them soon.
Thanks for sharing your experience with this model. What you're describing matches up perfectly with what I said in this video. If your center readings were too high and the outer edges were poorly lit, then your light was too close. That's the light physics of this unit. It should have been raised higher for more even coverage. I'm at Mar Hydro's site right now & I don't see anything for an FC4500. But I DO see an FC4800. That type of model is _EXCELLENT_ for even coverage at much lower hanging heights. It should be positioned totally differently than the SF4000. I don't agree with the specs for the FC4800 though. The Par Value seems to me, to be fabricated. I don't believe this light puts out 1649 umols while drawing 480W. That would mean 3.44 umols/J. I don't believe it. And so I have difficulty trusting their listing...
@@Albopepper Sorry... I confuse the 4800 and 6500 model numbers because I have them both. As for having the SF4000 too close, there are limits to the hanging height inside of a tent due to the wire hangers so I can agree to a point... But even raising that style of light higher will only moderately raise the readings at the edges of the fixture; you simple cannot have proper intensity where there are no diodes which is why I prefer the strip style fixtures. I'm sure the Mars readings are not 100% accurate either, but what I'm seeing on my meter is more than enough for flowering even at extreme levels over the entire 4'x4' area... Which was not the case for the SF4000. Real world, it simply wasn't enough coverage for a 4'x4' growing cannabis to the results I expect.
No worries about the model number! At least I was able to figure out which one you meant. Being physically constrained by hanging height is a real issue. I'm glad you brought this up. Hopefully it will inform others who have vertical limits in their tent size. In your situation, it sounds like you made the perfect choice by switching to a system that has a broad diode layout. What was the distance that you had between the SF4000 and the plant canopy? That info might be able to help out other viewers. No CO2, right?
@@Albopepper Hanging height is a big issue with these kinds of intensity (especially without knob dimming), and this was in a full size 8'x4'x7' tent... The SF4000 was 14-16" from the majority of the canopy, so it was not especially close. I didn't see any bleaching or other signs of the light being too intense, but I could not move the light higher without discarding the wire hangers... We could really use a low profile hanger to make use of the extra foot of space. I don't run Co2 in that tent, but it does average about 600ppm+/- due to it's location inside, so I think I fared better with light stress than would otherwise happen.
Thanks for that! So planning on 18" as a minimum was good advice then. But yeah, custom hanging wires might be needed to achieve it. In my little ghetto grow chamber I had to do exactly that to conserve space. I ditched the OEM wires and used some hanging chains instead.
the new 2021 sf 4000 has way better light distribution they spread the diodes in the center and packed them in tight around the corners. you can get really good par values on the edge's without getting too hot in the center. glad to see spider farmer taking feedback on their lights and making improvments.
Great and honest review as always. I do wish Spider Farmer would come out with linear/rail version (e.g 3"x 4' or 2') that would allow us to change the configuration around for something other than a square tent. Until then I'll just have to keep building my own
Another great review and appreciated. Nice job! Might have been an improvement for Spider Farmer to space the four boards out, instead of clustering them for better corner coverage and more even lighting.
Good observation Matt! Yes, spacing out each board would provide more even coverage. That would be most crucial for growers who are limited on vertical space.
Nice video with solid info! It's obvious that experienced grower's knowledge exceed the one of an average marketing department employee 😊💚🐛. Btw. there is some benefit in using two SF2000 (or four SF1000) lights instead one SF4000. With multiple lights you can get more even spread (less hot spot).
Thanks for watching! If your growspace is rectangular then the SF2000s are certainly going to be more flexible for creating uniform coverage. In a perfectly square tent, there's less advantage to using the 2000s. Perhaps if there is very little vertical clearance then the 2000s might work out just a little better. But with a my smaller tent size recommendations, along with sufficient hanging height, the SF4000 will do rather well.
Thanks for sharing the last thing I need to complete my I door growing set up this winter has been the lights so much misleading online it's hard to decide what light set up to buy
I’ve got 2 of these mounted on light movers in tents. I am very much using them wrong, but because I know how I’m using them wrong, I’m using them “right” for what I’m doing. I’ve got one fixture per 4x8, and have some shadows as it moves all the way. But, i do think this can cover a 4x6 tent on a mover and give the maximum potential yeild the light can with relative ease.
The fact that you could even get ahold of Samsung to find out the reason for price fluctuations is amazing. Gives me faith that someday I might be able to source leds from them. Hahah JK prob not. Idk if it’s because of Covid but I can’t even get the led stars, or individual diodes to reflow myself that I’m looking for. I just made one 730nm module to add to my HLG650R lights. I wanted to see if I could do it first( never even soldered until now) so I only ordered 21 triple 20mm star mcpcb for a small Slate single QB648 light. I’m trying to go 1:1 wattage wise with the 730nm to Quantum Board total( I know it’s not commonly used at all let alone at this level )
Thanks for watching. This video compares multiple lights that are all designed for a 2' x 2' tent: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WmjOSzSF-HI.html
This upgrade is a long time coming friends 👍 I have burned some medicinal peppers with the sf 4000 turned down to two hundred and seventy-five ish Watts. I would have been more prone to turn the intensity back sooner if my light has this upgrade. The very next run I decided to go back to my blurple for veg and save the sf 4000 for flower. It’s a strong light for sure worth the money once I figure the height out better.
Hypothetical question: If I make an array of ultra-high-efficiency home-lighting LEDs, like the one you show at 6:23 (say in the 120 lumen per watt category), would these be an okayish alternative for grow-lights? If I supplement the warm-white with a few "special" LEDs, say 395nm or 750nm, would it make growth meaningfully better? I'm not looking for "medicinal" plants, just kitchen-garden herbs; the ridiculously cheap home-lights (2024) are skewing the "bang for the buck" story, imo.
LOL, thanks! Yeah it took a little time, but the numbers should help people to see the overall light distribution. Hopefully it serves as a useful reference!
Hey Albo, really love the content. I could tell you put so much attention to detail into your videos. I have a question regarding finding the optimal distance from canopy + how hard to drive the lights. I'm currently using 5 strips of samsung SI-B8VZ91B20WW in a 4x4'. Each strip gets 100W so total of 500W(max driver can go). I can get same amount of PPFD if 12" from canopy while using 300-400watt as opposed to 20-30" at full 500W. Which would you pick and why?
Hi. First of all this was a very great review. What do you think about the Lumatek Zeus 600 Pro (EU) or the Photontek X 600 Pro (North America)? Would you recommend this light for a 5x5 or for a 4x4? Lumatek aka. Photontek says 5x5 too like they did at Spiderfarmers but i'm not sure if the numbers are good enough for a 5x5. I would really appreciate your opinion.
Thanks for watching! I think you are on the right track for a 5x5 area. The higher output units can achieve higher yield for that larger area. I reviewed a similar product here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PCaesi_M5DQ.html That style of light is very nice as it allows you to hang the light much closer to the plant canopy.
The original way to dim was a total joke and waste of time, but the upgrade is now exceptionally awesome, good save Spider farm I'm buying a grow kit once I sell this guitar on Ebay Australia :-)
he only US labor on an HLG is loading the Japanese LED board stuffers and putting quantum boards into a shipping. box. The LEDs and and PC board are all made overseas.
@@Albopepper Thank you for responding ... we enjoy your videos. btw... can you do a video on how much the the Samsung/Osram LED fixtures dim over time? For all I know 2 years down the road they lose 20 percent lumen so your stuck with a brick. I want to migrate from HPS but nobody has done long term. Do have and links to long term test? Thank you a million, Mack
The term to search for is "lumen maintenance." The LM301B diodes are marketed for being both highly efficient and also for having higher lumen maintenance vs many other diodes on the market. I'd love to see more info on the topic as well. I've had to dig through various product specification pages and even still, it's hard to get concrete numbers and specs for comparison. I know the Samsung diodes perform very well in this regard, but I have yet to find a complete database comparing multiple diode brands and models, let alone when compared to other tech like HIDs and fluorescents.
What do you recommend dimming knob to be set to in flower? +Spider Farmer 4K 18 inches above canopy. My ladies are 3 week in flower and 100 percent happy and healthy. This is my first run with the SPF 4K.
Some types of plants can do ok under 24hr light cycles. But not all plant. Many of the high light flowering plants require a 12/12 cycle to complete their reproductive phase. Something to keep in mind.
I recently bought an sf2000 and they have switched to an uneven diode distribution (biased towards the edges); from pictures, they seem to have done the same to the sf4000. Can we expect more even PPFD coverage?
What low profile grow lights do you recommend for seed starting on tiered racks? Your product reviews seem to be for very serious indoor hobbyists that want to fruit indoors. Do you recommend the barrina leds that look like t8s?
I have been thinking about this video since I saw it the first time a couple months ago. I would like to know what the lowest setting on the dimmer knob one should use, without a reduced yield. I think this light is very strong, and at 100% it's just too much. What do you think? I would like to reduce my electricity consumption with this light, without my plants suffering.
Hi Ellen, could you please describe your grow setup a little? Plant type. Number of plants. Coverage area. Is it in a tent? Perhaps it could be dimmed, but these factors will impact that.
Sylstar is also very good, I run a SF2000 in a 2x2x5 and a Sylstar GL2000 I picked up direct from the supplier in another 2x2x5 and Imo it's just as capable. had some real healthy tomatoes and lots of yield running a single hydro set up in each.(oxy pot)
I just picked up their entry level 110watt light to check it out. The quality control was pretty bad but if the diodes are indeed genuine lm301b then it's very good value. I probably paid less than half the price of the spider farmer light.
So my question is this. With 2 Spider Farmer 4000’s in a 4x4 tent I have what should the light be set and how high? The plants are in the flowering stage but so far the light is set at 22 inches and around 30% Brightness. There are 11 ILGM White Widow in the tent. It has a auto watering drip system and the lights come on at 5 AM and go off at 11. They were planted in 3 gallon fabric pots 24th of August. The soil is a mixture of Fox Farms Ocean forest and Happy frog and another soil with no amendments. They are mixed 1/3 each to keep the soil from being to hot for the seedlings. Until last week they did not need or receive a feeding of any kind just PH water in low 6 ranges and the PPM is only 200 from my water source. I wish I had PAR mater but do not have one to test it.
This image shows a simulation of how 2 units would appear if placed side by side at 50% dim: albopepper.com/images/SF4000x2-side-by-side-dimmed.png There's no side reflection, but already you hit almost 1000 PPFD across much of the area. Using an 18hr light cycle at an average PPFD of 1000 yields a DLI of 65. This is pushing the limits, but experienced growers have done it. If you want a lower DLI, like 45, then 700 PPFD @18hr will do the job. To hit a DLI of 45, I would be using the 2 lights at 165W each which is about 1/3 power. Distance of 18" should do the trick. Of course, the bigger question here is: Why buy 2 lights only to dim them down? Is it a lack of vertical clearance? Otherwise, I would expect a single SF4000 to do the job quite nicely, giving a faster return on investment.
@@Albopepper It’s not a lack of vertical clearance they are WW auto flowers. We really just wanted to try it out and was not concerned with return on investment. I am however fascinated with your ability to use your PAR meter and make the charts. We may use the second SF4000 in another application at some other point. I believe we left them set around 22 inches at the 30%. range. We travel so I don’t remember exactly. It’s been a week or so and will be seeing them today when I return.
@@Albopepper can you run your PAR test on 3 cannons in a 4x4 tent? www.blacksailmarket.com/meet-the-cannon Currently we have 3 running in a 4x4 tent at 200 watts each. Your ability to measure PAR is greatly appreciated and your willingness to make the charts and graphs for a stranger is beyond exceptional. Your channel deserves way more followers.
Thanks for your kind words Kevin! I checked your link and the seller doesn't show a PPFD map, nor do they state the Total PPF. But with a little math you can figure out the output. They list an efficacy of 2.0 umol/J. So multiply that by the power (332W) and the Total PPF should be 664 PPF. That is 55% of a single SF4000. If you are running 3 of those units at 200W each then the combined output should be 1200 PPF, which is the same as if you had a one SF4000 running at full wattage.
What do you think about BXEN-50S-11M-3C-00-0-0 as grow lights? The 50S model has (according to the datasheet) little bit better spectrum with much lower price.
I'm in the market looking for a new full spectrum light around the 220w range. You sold me with those discount codes though. My choices were for: (2.3 x 2.4 ft/ 4 plants) PerfectSUN Dwarf star 240w $562.17 (modernized replacement) Spider Farmer SF-4000 440W $660 (with your discount) MIGRO ARAY 3 | 270W full spectrum + red $515
You should do a review of the Geekbeast Pro 630w vs SF 4000. Which would be better value for money? I understand that the 630 would need to go on a 5x5 due to ppf intensity, but wondering per $ which is the better light for maximum production?
When you compare the total light output vs the cost, both light options offer the same value. So for the smaller 4x4 tents, I would say the SF4000 is ideal (assuming you have adequate vertical clearance). And for 5x5, the Geekbeast model is a really good fit and equivalent in value (PPF/W). The smartphone app is an added bonus too.
Hi Lokas. That's an excellent question! I've looked into the specs sheets for the LM301B and compared them to the LM301H. As it turns out, they're the same. You are correct in suspecting that it's all a marketing strategy. The LM301B are rated according to lumens measurements. The LM301H is simply measured and rated for PPF umols. However, they generate the same light!
I’m choosing one but to figure out which one I’ve a question: for auto-peppers 😝 20/4hrs what is the DLI to aim for? 500 ppfd x20hr are good or not? Thx
I've done a lot of research on this subject. Whether you're growing auto or photoperiod peppers, Spider Farmer is the best value for money. You cannot go wrong with them.
Hi great video. Looking at leds after a 2 year break. Question is I can pull 12-18 ounces from a hps light over a 4x4 table depending on the strain . Can an led pull these types of weights?...don’t worry just looked at the price for 1 in Australia 1200$....no thanks
Thanks for watching! LEDs can match or even possibly exceed growth of an HPS. It all depends on the light specs, especially the PPF output. Photons are what drive growth and a certain number of photons are needed to achieve a certain amount of plant mass. So you need to pick an LED that matches or possibly exceeds the PPF of the older HPS. This can be done, using less wattage consumption with less heat output. This video gives some tips for comparing HIDs with LEDs: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PCaesi_M5DQ.html .
Thanks Mickey! Sorry, I don't measure lux for grow lights. Counting PAR photons is more accurate for horticulture applications, especially with custom LED spectrums.
@@Albopepper No worries, I know what you're saying I just don't have a PAR meter, haha ...I do have a lux. I was hoping to see some type of relationship between the two meters that I could use to compare to the lights I have now. I want to upgrade them but, I'm trying to decide between the spider sf 4000 and the mars fc4800. 4x4 tent. Thanks again!
Both should have similar efficacy. The SF4000 might be a slightly better value if you are looking at PPF (light output) per dollar. But the light distribution is totally different. If you don't have much vertical clearance, then you should definitely go with the FC4800. That assumes you have plants covering the entire grow area, such as a Sea of Green application. If you have plenty of height and you have a few plants grouped in the center of the tent, the SF4000 is a good option.
Vids like this one sometimes make me really angry. And all because I can give only one like :P Excellent content, super informative - subbed! Keep up the amazing work
Would you say Id be ok to plug 2 sf4000s daisy chained into a surge protector in my apartment? I have a 4x8 tent that Im wanting to go from seed to harvest in. Any suggestions would be much appreciated.
The surge protector should be properly grounded. Two SF4000s should pull about 920W and 7.6 amps. As long as your surge protector can handle that, then I would expect it to be ok. Hope that helps!
@@Albopepper sorry USA, was thinking going by your vid that by clicking on the link provided I would save more than just ordering it directly from Amazon and not using your link. Your price is the same....
Yes the LED would be an excellent replacement for HPS. But you just need to be sure you are replacing with an appropriately sized light. This LED, for example, would not be a good replacement for a top of the line DE 1000W HPS. Some growers select LEDs that are underpowered for the task and then they complain that the LEDs don't give good yield. But they didn't select strong enough units for replacing their HPS.
@@Albopepper first off i want to say thank you for the respones brother. That is so true , ive had exp growers insist that LED is trash but LED seems to be upgrading with technology and HPS seems to be the same. That makes sense though , what would your advice be on selecting a good LED? ive heard it's better to buy expensive LEDs as they save money in the long run
hello sir. Thank you for what you do. Man you talk about a rabbit hole. Trying to fond the right light for the money is always difficult. I am growing in rows about 4ft wide and the row length is not a big deal because i can put as many as i want long. Would you recommend this light over mars hydro FC3000? Im trying to find the right light for my farm. Being way more informed than I am, what light would you recommend. Like everyone, Im looking for the best light for the money and I defiantly respect your opinion.
To achieve similar light output, you would need nearly three FC3000s for every two SF4000s. If you are tight on vertical clearance, then the FC3000 would be able to be placed closer to the plant canopy (good for rack systems). If you have plenty of height, then the SF4000 can be placed a little higher. Both offer a similar value in price and efficiency. So I would think about how you prefer to place your lights and then go from there. If you are considering multiple Mars Hydro units, you should ask them for an Integrating Sphere report to verify their specs. Their spectral graph doesn't really show Far-Red even though they claim to use diodes for it. And their PPF numbers don't match up. So I would use caution if selecting their product.
@@Albopepper Sir, thank you for the response. I have purchased 12 of the mars hydro FC3000 and no matter what i get underdeveloped "flowers". so i have since purchased 7 of the Enlite Ceres 780W 3500k+660nm. I sure hope they do well. Again, thanks for what you do. Huge help to have a pro to speak with.
A pretty informative video, i have been experimenting with a few type of light so much so that i apparently forgot to look after my chili. My chili leaf have this yellowing with black spots on the tip, this mainly happen on the top part of the plant with the small leaf on the bottom part just falling without any visible reason. The new growth also have this weird black/very dark purple coloration and are very sensitive to rain as they fall when it rain. The underside of the leaf look like if the leaf is soak in water even though it's dry on the outside, that might be because it have been constantly raining this past week and when it's not raining the sky is very dark and cloudy so it doesn't dry properly but I'm not sure, any idea?
I've tested the color spectrum of these Spider Farmer lights using many food plants and all of the plants did well for me. But this model is very high wattage. I'm going to use it for seedlings, but I'll be dimming it way down to 100W. I'm covering a 30" x 30" area. It doesn't make sense to purchase such a strong light and then dim it so low. You just want to grow in a small area, under the footprint of the light, is that right?
Should my Spider Farmer sf2000 light intensity be set at 100 power, at the recommended distance or am I supposed to set the light at the recommended distance, but then dial down or up the power depending how the leaves are responding. Not sure when I should use the power at 100?
I need sunlight, you're talking about daylight here, what advice can you give me? What should I buy? I have 3 plumeria plants that need sunlight 10 hours a day to bloom. Thank you
I've been tempted to upgrade my medicinal tomatoes grow with spider farmer lights. My grow space is a 3x2 by about 6 feet high. My current setup is older led technologies with the blurple spectrum and fans. What light would you recommend for my space?
I think the SF2000 would work great in that space. Plenty of light. Might even be able to dim it just a tiny dim. But the proportions would certainly be perfect.
I get the value prop for buying a light that's twice the size, but not twice the cost, but I have plants that grow at differing rates, and need to use a high light, and a low light, especially w/ seedlings. Isn't this a typical scenario?
