Do i need special glasses when amending my plants with the spider farmer led? And would it be harmful to my skin after a long period of time.

[@Albopepper]

@@Sarah-wt2zk I don't stare directly up at the diodes. That being said, I don't wear any glasses when using it. And it does not produce UV, so it is safe for skin. Here is the spectrum: albopepper.com/images/spider-farmer-sf1000-full-spectrum-led-grow-light.png

[@Albopepper]

the SF4000 has higher light output, a better spectrum & a lower price.

Thank you Big Time for explaining stuff and for keeping manufacturers honest by calling them out on their BS! There's too much rip-off out there lately online! We depend on people like you and you're few and far in-between. Excellent work!

[@lightworker303]

Doing my own research, before reading reviews, and watching videos I chose to get 2, Spider farmer 2000 lights. Everything I keep reading backs up my research, that I made the right choice. They seem like great lights with very low power consumption!

[@glenng.5726]

By far, the most entertaining light science videos on the internet. I watch a lot of them, most are boring & overly complicated. Your videos make learning fun & I retain the knowledge. You are an excellent teacher.

*$50 Amazon Gift Card!* Recently I encountered a situation which caused me to tweak & reupload this video. Even though it had just hit 149k views! To rebuild the video's performance, I'm awarding a $50 Amazon gift card to the FIRST KZbin viewer who can reasonably guess why I re-uploaded the video. Each viewer gets ONE guess which much be posted in the video comments. You'll need a valid email address for finalizing the reward. _(Sorry but my family members don't qualify to enter.)_ See if you can guess what happened!

Where u a little to kid friendly and it locked u into youtube kids?

[@Albopepper]

LOL No. I'm glad I didn't build a channel around videos for kids. What a mess for those guys!

[@pete1853]

I'll guess that it was because of you mentioning "marij... Tomatoes" and youtube demonitized it.

I couldn’t be happier with my SF-2000’s. They’re such an amazing light, especially for the price, plants are loving it.

[@Albopepper]

So glad to hear it!!!

[@lylezoethout8540]

I'm running an Sf-2000 as well. Difference is night and day and ya, that cost? How could you go wrong. Plus, if you contact them directly, they're usually willing to discount at least 10% of whatever the current price is. On top of deals that may already be on. They're competing in a high competitive, new quantum board market and love/need exposure. Just in case you ever want to buy another one😉!

[@margiefaye2196]

AlboPepper , I was initially going to get this LED but opted for a 600W wakyme, considering it’s my first attempt. First attempt has proven to me that I’m capable and to be honest, I’m obsessed with this hobby therefore it’s time to upgrade. Hindsight, should’ve bought spider from the start. So..I’ve got a 3x3 with a TomJuana that’s fixing to flower and my sprouts (4) are in a closet I converted to a makeshift grow room with a crappy Walmart light. I am remedying that right now-if I get another 3x3 should I get the 2000? I don’t want to get another subpar light again, but I don’t want to over do it either. Can I go bigger with tent space with the 2000? I know you covered this , sorry,

[@GraeMatterz]

Nerd alert: You gave a passing mention to the coating covering the Spider Farmer. I used to work in the semiconductor industry on monitoring/testing systems in caustic or acidic environments that used that kind of clear coating. It's called conformal coating (but we called it caramel coat). It's a mess trying to repair something covered in it and then it had to be reapplied in order to reseal the spot. The reason it was so hard to work with is because it's so durable that it even resisted the solvents needed to melt it to make the repair. The fact that they use it when it adds cost to the process is a +1 for me.

[@GraeMatterz]

Maritomatoes! LOL. Kinda like Cannabeans.

[@Loroini]

Hi ! you seem to know your shit, do you think its possible to apply heatsinks with thermal paste to this coating to help it cool or it not recomended?

They may need a dormant period in cooler temps but I don't know for sure.

[@eugeniahobbs41]

This is the much greatly improved videography of Albo Pepper. You have an excellent presentation, content and performance with this new video. Please note that there are numerous folks and light manufacturers out there that still embrace grams/watt as a valid method to evaluate grow lights. However, when we discuss grow lights today in 2020 much scientific measurement theory is now pedestrian. In that effort, to name drop we need to check Shane, MIGRO and Bruce Bugbee, Apogee Instruments, among many others to observe that the grow light discussion has matured into a verbal lexicon that you have so eloquently presented. Thanks for providing this information.

[@TheMolly201]

Hello thankyou for running this you tube demo. I have just bought the Quatum LED SF 1000 light for my Hoya propogation. My question is this. How high above the plants should the light sit? I will have them in a 3ft by 3ft reflective lined box. The plants are in clear plastic boxes to keep in humidity at 70% and heat 22 degrees. I have heat Matts coming and will have to figure out the heat in the plastic boxes by shifting their lids. But it's the height of the light I'm not sure about. I'm also not sure how long I should have the light going for. I'm watching your SF 2000 and you explain all my questions but I have the SF 1000. Inally its summer here I keep the plastic boxes at 23 and humidity of 60% ish. But I dont want direct sun light on them and naturally as the sun leaves my morning window I loose light so, is it better to grow them under the quantum or morning dappled natural sunlight... I'm a total virgin grower and learning hence me watching you...looking forward to your reply. Kate New Zealand

[@luca920]

I recently built myself a 250 Watt board with Samsung Horticulture Linear arrays (L2). It's really simple: Go to DigiKey, buy the modules, an adequate heat sink, drill holes in it, put thermal paste on, drill holes for hanging cables, buy the adequate Mean Well Driver and you're good to go. 2.7 umol/J, lots of blue, red and a bit of green. At full power, the heat sink gets up to 45°C max. You can't go more efficient than that (for this price).

[@oxossigarden565]

Great stuff Albo!! Thank you for the great work you are doing and putting it out there :)

[@x2100]

I almost ended up getting a blurple light for around the same price as the SF-1000. Thanks AlboPepper! I got the light in today and they come with a separate dimmer now! Not the one behind the driver.

[@mysticwolf60]

Great video Albo! Appreciate the info.

[@jetsillinizoufan-3321]

Absolutely love how you make fun of the crap 3 bar led light at 7:10.

[@walleye855]

Thanks Albo. Another great job.

[@NiMareQ]

What is the system at 8:03? Perforated pot to regulate moisture and air flow, and automatic watering via those pipes?

[@Albopepper]

Yes, those are some cool pots! They are intended to air prune the plant roots, reducing root circling. I think I got them from Greenhouse Megastore.

[@BillyBadass]

Might I suggest looking at the "clones" of the brand name competitor? Meijiu 480w and Kingbrite 480w are effectively the same chips and boards, and it will give you an additional opportunity to cast massive shade on the chinese middleman resellers. Bava makes some quality looking lights, but I don't know if their 720w is a true 720, since I can't get any light maps from them.

[@jeffking2214]

For growing leaf lettuce, using this light, what would be the ideal distance from the light to the lettuce plants?

[@Albopepper]

The distance impacts the light intensity. And there is a direct relationship between light intensity, light duration and plant growth. In a 28" x 28" area, a distance of 24" would work well. But you need to also select the appropriate light cycle. Probably a 12hr ON / 12hr OFF cycle. That should produce a DLI of about 16. To cover a larger area, raise the light and then lengthen the day cycle duration accordingly.

[@redpandatronics6185]

Thanks for giving temperature values in Celsius too and not just Fahrenheit

[@IntentsGrowing]

Awesome Review, you get right into the good stuff! Did you Re post it because a company did not want to be shown as over priced lol

[@Albopepper]

Thanks for watching! Good guess, heheh. Some companies definitely don't like the competition from Spider Farmer. But there was more to it than that.

[@IntentsGrowing]

@@Albopepper hmmm perhaps a strike from not claiming the fact you bought the light the first video

[@Albopepper]

Each person only gets one guess. ;) However, I can assure you that that's not the reason. I decided to add in the text because I was re-uploading anyway. I had originally made a disclaimer at the end. But I figured it would be even more transparent to post the disclaimer at the very beginning too.

[@hamsterSNAKE]

How is this light still holding up....I've seen it review by a bunch of people but I enjoy you in depth review. Thanks keep up the great work and stay safe

[@Albopepper]

So far, so good. Been running the SF-1000 at 100 watts and the SF-2000 at 75 watts for 5 months. Plant growth has been the best I've ever had. Quite satisfied so far!

[@hamsterSNAKE]

@@Albopepper awesome, I'm really think I might buy myself a lamp or 2 to start my hydro setup. Been watching your videos for a while and I love how in depth you go with your analayse. I will try and use that promo code of yours once I get out of the hospital and get settled back home. Take care and stay safe.🍻

[@gagoxxxx]

Great content !, thanx for sharing. I would like to point out though, that comparing PAR efficiencies of lamps with different spectrum is like comparing apples and peppers :). A grow lamp with high blue content will have much better efficiencies than one with energies distributed more evenly across the whole visible range. Needless to say, if a grow lamp has UVB or NIR, that light will reduce efficiency. May be you could shoot a video and explain what is your ideal spectrum for different plants. Cheers

[@gagoxxxx]

Another misconception when reviewing grow lamps is about the temperature of the heat sink. A relatively cold heatsink could mean that it is failing to dissipate heat correctly. Only way to be certain of the quality of the lamp is to measure the LED temperature and make sure it is below the recommendation. Measuring LED temperature is by no means straightforward though.

[@kevinnolastname2220]

I could be wrong, but I was under the impression that the "replaces 1000w" claim is in reference to 1000w hps or mh lamps

[@Albopepper]

Hi Kevin. If a seller intends to claim that the light replaces a certain wattage of HID, then they need to state "replaces". They can't just put a fake wattage in the product title. Even still, these sellers are _grossly_ overestimating the replacement capabilities of their lights. In this video, I give some examples of what an LED could realistically do compared to an MH or HPS: kzbin.info/www/bejne/hnTElqaflLJoerM

[@dolphindolphin7567]

[@deblosey811]

I have a variety of succulents in my garage for the winter. I have about 60 small plants. Is this a good grow light for succulents to keep them compact? Your video is very informative. Thanks!

[@bsimpson2288]

Nice vid. I was just looking at this light and wondering if it could do anything. Only thing that scares me is I think I read that they are made by Meizhi. I had one of their lights before where the bloom switch went out within a year, I contacted them because I was within warranty and all they wanted to do was send me a replacement chip and instructions on how to solder it in. Also wanted to charge me for the shipping. Crazy. I hope I’m wrong though because this light sounds good. Except for the name. Reminds me of spider mites...

[@Albopepper]

Thanks for watching. From what I've read, the Spider Farmer company is an independent branch. In general, one thing that's nice about these light designs is that there are no switches or fans. Much less circuitry to fail. And the driver is a much better quality driver than others.

[@drewgrows7765]

The old philosophy for a LED lights worth was how big the diode wattage is. Example 5 watt diodes are going to penetrate deeper into a Canopy than 3 watt diodes. Then of course they went larger as you know with 10 watts. This light appears to have more diodes so I suspect the diodes are of a low wattage. What are your beliefs on this?

[@Albopepper]

A photon doesn't know what diode it came from. All PAR photons have the potential to drive photosynthesis. But if you want to boost production and growth then you need to boost the number of photons. Photon quantity is what really matters and that's why we measure the PPF of a light or the PPFD over the surface that is illuminates. For better canopy penetration you need more photons. Also you might try to scatter those photons in various directions across the canopy. And something that helps quite a bit with that is including green photons. Those colors penetrate deeper into plant tissues. They also bounce around and hit lower leaves more easily. That's what counts. So what is the total light output of a fixture in PPF? And how efficient is it at converting electricity to light? That's what I look at. This talk about 5 watt and 10 watt diodes is all a bunch of smoke and mirrors. It's marketing hype designed to distract consumers from what really matters. A photon is a photon.

[@drewgrows7765]

Thanks for the reply and info👍

[@terrysun5845]

Great video！Just wondering that are all these theories applies to aquarium plants as well ?

[@Albopepper]

Thanks for watching! The concepts here apply to any plant light, since plant lights should be rated with PPF values rather than lumens.

[@cj.alvarezpereira]

What is the gauge of the aluminum sheet the PCB array is affixed to?

[@Albopepper]

The seller has revised these lights since their original release. I advise asking that question on the Amazon product page.

[@agerlock917]

Have you heard much about the Meijiu lights from China (Alibaba)? I got one for Christmas, but I don't have the proper equipment to test the PPFD. My 240W model cost about $180 shipped, and I would love to know if it holds up vs the SF. Mine uses Samsung LM301H chips too.

Great review. I’ve been looking for a light to grow lettuce, peppers, tomatoes, strawberries, herbs and kale. I’m going to try doing this all hydroponically using the Kratky method. I’m very excited to have some fresh produce. This light seems like overkill but I like the quality, efficiency and dimmability. I hope this light lasts a long time and works well for a variety of veggies and fruit. In the future I’d love a video showing what you think is an ideal hydroponic Veggie grow setup is with affiliate links to everything you use. And show you setting it up. And you could do a follow video of you setting up hydroponic veggies in it (Kratky method preferred). And then you could do follow videos of how things go with it.

Is it right to consider an auto just like a photop. in full veg? Is it right to give her no more than 500 ppfd (or 33k lux) of good spectrum grow light? Thanks

[@growerjoe9186]

Was wondering if u ever used the haofst 1800 watt led it is 300 actual watts it has 6 50 watt 1 inch Cobb LEDs it is about 105$ on amazon. Just curious on the actual specs. Cause it is doing very good for me I think it is a great light

[@rae7305]

Would you still recommend this particular light today for $150? If so, do you believe one of these would be sufficient for 2-3 autoflowering maritomatoes (housed in a 32"x32"x63" grow tent)? I already purchased one after watching this review, but I'm wondering if I will actually need to buy another one. I'm hoping that isn't the case since I'm not sure I can really afford a second one of these, but I don't want to start a grow if I can't provide my plants with the energy they'd require. I'm new to this all, so I truly apologize if these are silly questions.

[@Albopepper]

Hi Rae. Your questions are not silly. They are very good questions! Let me ask you this: Are you planning on doing a Sea of Green? Are you planning on 18hr light cycle? Or 24 hr light?

[@rae7305]

@@Albopepper Thank you so much for the quick reply, sir. This will actually be my very first grow attempt, so I was going to try to avoid manipulating the plants too much in order to get a feel of how the plants grow naturally. I love the idea of doing a sea of green (or screen of green) to maximize the space/light, but I embarrassingly haven't researched either technique enough yet to know how to properly/comfortably pull it off. However, I will always yield to expert advice and will start studying up on it if you think this is the way to go. I was planning on doing an 18/6 light cycle simply to conserve some energy, but I am 100% open to doing a full 24 if that is what it necessary. Thanks so much again. I am eternally grateful to you and your amazing videos for helping a "black thumb" like me learn how to grow my own medicine.

[@lailingngan8231]

Dear Al, I want to start growing microgreens very soon. I have seeds (only three variety since I this is my first try), will watch your video about potting mix next before ordering potting mix, and plan to get the light (Spider. . . 2000) from Amazon. The latter two will come fairly quickly. I have a question though. Can I use the lighting without a grow tent?

Yes indeed. I made some tweaks though. If you read the other comments, you can see that I just had a contest. A $50 Amazon Gift Card was sent to the viewer who guess what caused me to re-upload. I'm trying to drive traffic so this video get picked up again as the previous was performing quite well. There's some new stuff at the end that you might appreciate.

@@Albopepper thanks alot for the fast and super nice to read answer. Apreciate your work

[@bettergrow2302]

Very professional video. Do you have any idea about Mars TS1000?

[@Albopepper]

I haven't tested that one but thanks for watching!

[@jde9095]

Great review, got me clicking the bell ;-)

[@cris-vv1pn]

What's the difference between SF 1000 compared to the mares hydro TS1000?

Question, what is the theoretical limit for PPF/J?

[@Albopepper]

"The theoretical maximum PPE for LEDs is 4.6 to 5.1 μmol·J-¹, depending on the composition of the LEDs used in an array." _gpnmag.com/article/plant-lighting-efficiency-and-efficacy-%ce%bcmol%c2%b7j-%c2%b9/_

@@Albopepper Wow Thumbs up!

@@Albopepper Wow, very informative article!

[@Albopepper]

I'm glad you enjoyed it! :-D

[@DMPB-fi2ir]

so lets see as a base line for months of june and july east coast USA receives in the range of 40 to 45 Mol.m^2.day ( DLI ), and during august drops off to a 30 to 35 range just to give an approximate reference point for growers

[@benmcelwain5301]

As someone who is interested in growing vegetables during the winter this review was useful. Many reviews seem geared only towards cannabis which I don't care about.

[@Albopepper]

Thanks for watching Ben. I'm glad this info is able to help out!

[@michaelpickett102]

What do you think about the 250 watt e39 replacement bulbs for reflective hoods? Is the $130 worth it?

[@arthurh1969]

Great video, I feel like I'm reasonably up to date with how LEDs are evolving and have been looking for a review of the Samsung chips. Is a 4 channel light good enough to mature a "non-medical" tomato plant or perhaps an indoor orange tree? I thought a tiny amount of UV would promote growth or shew pests. Does UV or more channels help?

[@Albopepper]

Thanks for watching Arthur. UV light does have some advantages as you've mentioned. But LEDs are less efficient at generating UV vs PAR wavelengths. I've seen good growth without the UV. But the broader the spectrum, the better. I think these particular models have a nice blend.

[@daleandallisondraeger8188]

Do you have any suggestions for a beginner/budget light for micro greens and seedlings

[@Coconutoilcrazy]

And all I want is a grow light :) Thanks for the info

[@Ser-xk1pu]

Hello?.Can you compare the led panel that you are using in this video in light efficiency between the cxb 3590 led or the citizen clu48?.Thanks.

[@JDB2030]

I cant find a review for the SAHAUHY 1000 watt grow lights. If you get a chance can you do one?

[@mikewalsh1616]

So if I am growing just one maji-tomato in a 4x4 with a sf2000 is this to much light in to big of a space for just one? Do I just germinate then go 18/6 with the full 200 watt at seedling or would a 2x2 with a 60 watt be better conditions? Just a little confused with that thanks for any help!

[@richgunckel6483]

So would you suggest the spider farmer sf 4000 for a 4x4 tent to grow cannabis.

[@Albopepper]

HI Rich. Yes, that application would work. Be sure to watch this follow-up video as well! kzbin.info/www/bejne/onyVaZSfh7aSjNU

[@mikev6999]

Looking to do micro greens, then in the future larger plants, would you recommend this light? At what distance, and would you do full power ( actually the 2000) or lowering it? Thanks love your channel.

[@noway8233]

The spectrum its seems to have too much blue , its even biger than the red ones , this is ok or not ?
