Sufficient LED for one plant
    #22113338 - 08/19/15 06:04 PM (8 years, 5 months ago)

I have come to a point where I have all the necessary components to grow a plant in my closet- except for one thing. Lighting. Ive been researching for a few hours now and I found a few products that look good, but I am struggling to answer one question:

Will these lights be able to grow a healthy plant, as the sole source of light.

this one:  http://www.amazon.com/Apollo-Horticulture-GL60LED-Spectrum-Growing/dp/B00FGFW0XO/ref=sr_1_5?s=lawn-garden&ie=UTF8&qid=1440026952&sr=1-5&keywords=apollo+light

I can't answer your question, but if your handy google diy cob led, build it yourself and know its good quality.

Trying to avoid hps. I'll probably end up getting one of these and a couple smallish cfl bulbs

Ey bud. First thing you want to look for with an LED before buying is how much does it *Actually* draw from the wall. The next thing is how much verticle room do you have? If you buy an LED light that uses 5w chips you're going to need to have it at least 10" away from the plant to avoid bleaching.

The "Erligpowht 45W LED Red Blue Indoor Garden Plant Grow Light Hanging Light"

After reading the comments I found that it actually only draws 36 from the wall. I don't recommend you get this one. Even if 45W was the true draw, it's still not enough for Cannabis really.

The "Apollo Horticulture GL60LED Full Spectrum 180W LED Grow Light for Plant Growing"

After reading in the description the actual power draw is 106w. Which is good for Cannabis. That light also has 3W LEDs so you're going to be able to get it closer than a 5W LED set up however I'm not sure on the specifics.

If you're going to buy either of them, get the Apollo horticulture 180W. You could grow Cannabis with either but you won't get much with the first one. It'd flower and produce bud, but it'd be very loose and not very potent.

It should also be noted that an HPS light source is cheaper to buy but you spend more running them and they give off a lot more heat.

I have a kessil h380 which draws around 80-90 watts and I would recommend it over any of the lights above.

I'd say a COB LED light would be what your looking for.

This might go off topic to your question but hopefully someone finds it useful.
Wattage and lumen output(think brightness) to a little lesser of an extent, plays no direct role in a plants growth.
When people say otherwise it's because these are buzz words.

Wavelength is everything.
I have never grown weed before, nor do I want to. But I have grown many plants inside during winter for fruit and vegetables. It is a great feeling to eat home grown strawberries and cantaloupe while its -30 outside.

Certain plants are more adept at absorbing different wavelengths(color). This means that you will never have a system that works on the same level as the sun for every plant you want to grow.

Everyone likes LEDs for growing plants because you can closely target specific wavelengths. If your LED runs at 460nm then the plant can potentially absorb all of that. It's not likely, but it is possible. For this reason we say LEDs are more efficient for growing plants. They are not the best though. Unless you have 600+ different LEDs to cover all of the wavelengths that the sun provides that a plant can photosynthesise, your setup will never be comparable to the sun, but that's obvious. Basically what I'm getting at is if you want to use LEDs you should invest in an array that contains LEDs rated for the 6 peak wavelengths that plants absorb the most efficiently. This includes 2 of the peak carotenoids wavelengths.

Another thing to consider, and probably the most important. LEDs currently do not output the wavelength ranges they are rated for. This is due to resistance and other things in the circuit(including age). They will always be 5-10nm off. You will probably never have all of your 465nm LEDs running at 465nm all the time.

[poop edit] I can elaborate a bit more if anyone wants me to go into deeper discussion about optimal wavelengths.
Also, CFL's work perfectly fine. Your plants will not be absorbing much of anything though, so they will grow slower. This is due to reflection and to a certain extent, refraction. But they will still grow.

Don't let oggy discourage you from an led grow, he's an LED hater. :rolleyes:

Check out this link

Decent LEDs tend to be pricey. I would vote against a cheap LED UFO and CFL lighting.

I should mention this is just a hobby, and im only trying to grow one nice plant (at a time) that I can be proud of. Im not trying to sink a bunch of money into this, its just something fun to do! I have a 2'7"x2'7" and 5 feet 3 inch tall grow tent that the plant will be growing in.

I see now, that the 45w panel i posted is junk, but you guys dont think the 180w ufo would be enough for one small plant?

Actually I prefer LEDs over everything else. I built my own array a few months ago that runs off of a deep cycle battery for power outages. The only issue I have with them is they generate a LOT of heat. The array I am using has 20 3w LEDs that target the 6 optimal wavelengths. The temperature is the big reason I am not using it currently. Also it really stands out.
It's perfect for tomatoes, though.

I am probably going to build a few more to mimic seasonal lighting. Surprisingly, the most expensive part of the whole thing was the aluminum heat sink and I had to mill that myself.

you couldnt use heatsinks off of ebay?
rahz and i have a thread bout diy cob led on the sister site(grower).
i just recently got outta a job so i wont be building mine soon... but he found heatsinks for his on ebay...
i like the reasoning behind building ones to produce mimicked seasonal light. thats awesome.
what wavelengths will that be
summer; fall; winter; spring?
awesome ideas jw what your build looks like too if you had to customize heatsinks and whatnot.
and we were optimally using 10w emitters. i also inquire how you like the smaller emitters over these bigger guys?
cheers

The heatsink I am using has a very particular use in mind. I want to have a fan blowing over it to warm up the room during winter. So I have very thin spines poking out of a sheet of aluminum. The light itself is only 12" by 5.5". So its not particularly large.


My opinion on using 10w over 5w or 3w is that they probably aren't the best route to take because for every one 10w you could be running three 3w LEDs which could provide more coverage than a single 10w. Also they're cheaper! IIRC it cost me $40 to build my array. The heatsink cost the most at like $15.

As for wavelengths, I researched a lot and found 3 wavelengths for spring/summer and 3 for late summer/fall. I am torn between using all 6 in an array or doing the seasonal lights. I know that the plants would be healthier with all optimal wavelengths on it, however it might confuse some plants that fruit.

I have a small paper with some of my research on it. I will look for it and post the wavelengths. It really was a pain to deduce optimal wavelengths from sources.

Dude if you already have that info wrote down somewhere and could share that would be awesome..... i think ive written a note about nm wavelengths solely best for cannabis and i think the veg[blue] was in the 435? range as you posted above i believe, and then it is best to switch over to the flower[red/orange] which it what im having a harder time remembering maybe it was like 760nm?? with some of the old blue spec added in.
anyway post your findings if you do come across them bc i sure as fuck love this new led stuff..
and i get the 3w are cheaper and you could 'cover' more area with them ie get more and spread them out... but how many plants can that suffiently bring to fruit and flower? could one make one[i believe Rahz uses his all the way thru] for both veg and flowering stages using both nm ranges? and do you think the penetration benefit that the larger w emitters give can be replicated/outweighed by the lower w spread out?
give me a few and ill post Rahz awesome ass looking one for ya, to show you what i mean. awesome you are experimenting with this. and if you are achieving some optimal results with your price range then this is intriguing to me. i agree led and light is all about wavelengh when it comes to plants, but barring we are not just growing one plant the stronger ones i think you will see are promising. although it depends your use... id like to see your small nicety in action for an idea on the light it puts off and cuz its cool as shit.
ill find that pic now..
cheers

ps your heatsink sounds awesome

i thought these were badass. member of shroomery built negros.

cant wait to start my own project, this is what i was speaking of bro.

QUOTED: I am torn between using all 6 in an array or doing the seasonal lights. I know that the plants would be healthier with all optimal wavelengths on it, however it might confuse some plants that fruit.

I just now saw this. and i think thats what most led guys are doing these days is using white[all??] spectrum light to give as many wavelengths as possible??
i may be mistaken i have to research more myself lulz..
edit:QUOTED from Rahz:
There is some science behind uv and ir supplements, but it's also a flashy selling point. To keep things in perspective you can see the spectrum distribution for white emitters on the datasheets. Compare that to a spectrum distribution chart for HPS. White LEDs are obviously superior to HPS with or without supplements.

I used all 3000K emitters on that lamp. Plenty of blue for veg.

cheers
