How are led lights?

[kylekyle123]

Im new to growing cannabis and was curious if i could use one Sunshine Systems 45WT LED Grow Light for 2 cannabis plants. Can I just use this one light to grow them or do i need multiple led lighting systems?

here is a URL for the light.

Sears: Appliances, Tools, Electronics, Apparel and more from Craftsman, Kenmore, Diehard and other Leading Brands (http://www.sears.com/shc/s/p_10153_12605_01299273000P?prdNo=2&blockNo=2&blockType=G2)

Sears has led grow lights now . . . :stoned: it truly is a brave new world. :D

Providing more than four times the output of the original GlowPanel®, the GlowPanel 45® uses only 28 Watts of power and surpasses the output of a 250 Watt HPS - easily providing five square feet of coverage for your garden. The GlowPanel 45 is a plug and play grow light - it works right out of the box. There is no need for any additional ballasts or refelectors and the GlowPanel 45 comes complete with its own hanging kit.

sounds interesting to me, too. sorry I've never used one yet but there are some led gurus on this forum that would no better but if its as advertised (equivalant to 250 HPS) then that should grow two plants. :twocents:

Now if they make a 12 volt DC version for my off grid garden then I'm sold. just kidding, AC inverters work well. :rastasmoke:

for roughly $30 you can get the same thing on ebay shipped from hong kong :thumbsup:

Quite right!
Overpriced rubbish. IMO
For the same $150 one can buy a decent led light.
Keep shoppin' brah.

^ speaking of one of our resident led gurus ... :smokin: I generally take anything Weezard says as fact.

you could probably order the same set up for about $50, even $40 for a kit that you can put together, but the question becomes is it worth $100 just for the peace of mind of not having to order something online, just being able go in and buy it for cash.

But, I doubt they actually stock these in the stores so it might be an order anyways. might check around for the closest grow store in your area, they even have them here in BF, OK :jointsmile: if you want to purchase with cash at a store, otherwise, if you don't mind ordering online, then yeah, I'd do some more searching.

and and oh yeah, welcome to can com!! :rasta:

anything that looks like a "lite bright" panel is a waste of time unless you build it yourself like Weezard :jointsmile:

And sometimes, not then. My first panel was inadequate.


Aloha Str8

Your timing is great.

Please show this gentleman a decent light.
And, what a decent light can grow.

Jus' hate to see folks waste mony on da crap kine.

@ Boaz.
"I generally take anything Weezard says as fact."
:S2:
Mahalo fo' da confidence, but,
I would not advise doin' dat.
Eveahbody's full of it sometime or other.
There are times that I've been quite "wrong".

I try to verify my source, of course.
And check my facts as well
From which end of the horse they come,

I'd really be interested in see what you guys have and how you got it and/or made it.

all the specs on the lights i use are on this website WEX-150:thumbsup:

if you want any hit my skype :jointsmile:

Aloha Weez...your posts always crack me up :smokin:

No problem, Mr. Nilly:).

Click on my avatar and look in da albums.

There are pics of the construction, with captions.

You guys are the greatest! :thumbsup:

I'm a n00b here, as you can see, but this forum is da kine! :rasta:

...Aloha Weez...your posts always crack me up :smokin:

me too. :jointsmile: perhaps I should revise and restate remarks. :D I take anything Weez and St8 say about led growing as fact. the proof is in the buds. :rasta:

I'm kinda leaning towards the home grown light bright model, preferably DC voltage. From what little I've read the size of the wattage of each individual led is important. as is the spectrum. I would think this was has the correct light spectrum but not sure if the wattage cuts it. tons of good info in this forum, too. :greenthumb:

[boaz]

^ kinda off topic but I was thinking about the lite brite grow kits and it occured to me since led can be put right against the plant without burning them then how about a string of led lights that wraps around the plant kinda like a string of Christmas lights wrapped around a Christmas tree? :detective1: I bet someone else has thought of this already but if not what you guys think??

Indeed they have.

However, just because you CAN put leds right up against the leaf does not make that a good idea.

Lemme 'splain.

There is such a thing as too much light.
And, of course, too little light.

Somewhere in-between is the "sweet spot" for cannabis.
If you place the source right against the leaf, there is no room for adjustment and each emitter only covers a very, very small area!
To cover a decent size plant that way. would require thousands of weak emitters.

Mo' betta, to use hi-power emitters from several inches away.
Better "blending" too.

I suggest that you google "Inverse square law", read a bit, then sit and think about it.
Could save me a lot of typeing, yah?;)

I'm saying that you are on the right track, but you need to gather facts, then spend some time and effort thinking about it.

All will become clear in time.:D

Aloha,
Weeze

[boaz]

^ cool. thanks Weez. Inverse square law, eh? gonna search that now.

yeah, after I thought about it a while I started thinking about some of the very same things you just mentioned. maybe wrap the lights around the outside of them, like on a circular fence not actually touching them, for a little added umpf down lower. but, I'm thinking now maybe you need them somewhat proportional and reflected to get the correct wavelength. :stoned:

but you are right, a little R&D may needed at this juncture. :jointsmile:

[kylekyle123]

ty, all that posted something.

[clongo]

i need a few 425-440 nm panels or spotlights and the same in 630 and 660 preferably just 660. anyone know where to get far red 730 also? thank you

[khyberkitsune]

The first (and likely only rule) when dealing with LED lighting, is CHECK THE SPEC. LED lights are good if you find ones with the proper wavelengths, the proper output, and a proper balance.

If you see "NASA Spec 7:1:1 or 8:1" RUN AWAY. Natural sunlight is NEVER that imbalanced, and the point of growing indoors is to emulate all the good outdoor stuff and exclude all the bad outdoor stuff.

White LEDs IMHO are a waste. I've got a quad-band LED panel with white diodes, and my tri-band does a little bit better.

Take your wattage, and divide that by the amount of diodes on the panel. Is the result 1 or greater? If not, it's not worth it, avoid it and look elsewhere.

Weezard, Stra8, they've got the pudding proof!


I've had great results as well, as you can see.

You can't listen to the marketing, because that's all it is - marketing. It's deceptive, misleading, and quite often flat-out BS.

Its the weezard!

You still have to give me a DIY workshop when I visit the islands. One day...
