LED questions

[lunarose]

Hi All,

I would like to add some LEDs in my new greenhouse and have some questions. The greenhouse will be on my deck and the plants won't get enough direct sun light maybe only 3-4 hours so I'd like to add some LEDs the problem is which one? Now the market is flooded with UFO know offs and those cheap panels I have no idea what would be good. The greenhouse will be 4'x6' so I don't need a lot and I don't really want to spend $600 on a PROCYON. Any suggestions?

a 4' x 6' grow space, and don't want to spend $600 ? ... I would suggest LEDs ain't for you ... if it's a longtime indoor-grown strain, it may be OK with 4 hours of direct light ... I have some that thrive in the shade ... :smokin:

Hey lunarose,

Image reaper has it correct, LEDs are probably not for you...at least in this application.

Four hours of direct sun and the balance indirect may be more then enough, but if you need to supplement light then HPS would be a better choice both for your budget and your needs.

Thanks guys. I guess I better start saving up the money. The reasons I want to go LED are that one heat can be an issue and more importantly I do not want to light up my deck at night.

Who do you recommend for the space? Procyon? UFO? How can I avoid cheap knock offs?

:D Dunno if you've seen a good led gro-light in person, but "light up your deck" it will!:cool::cool::cool:

Bound to draw lots of attention.

And I. R. knows what he's talkin' about.
Most strains have a very wide tolerance to light intensity and duration.

Most useful hint I have 'bout growing on the deck or in a greenhouse is to use wheels and save your back.

When I'm a week from harvest and subject to bud rot, it's almost guaranteed to rain.:(

I roll my ladies under an umbrella for the duration and the buds stay dry.
Then roll 'em back out when the sun returns.
Makes it a lot easier to bring the girls in when the neighbor's gardeners do their thing, too.

Aloha nui,
Wee Zard

her grows are also mainly autoflowers so they need all the light they can get, hey luna maybe ask weezard some good specs, since he has an awesome 45w led setup he built himself

[lunarose]

Hey Wee zard! How are you our magical scaley friend;) I am hoping to be able to grow year round in the GH both AF's and regular strains. Having on the deck will allow me better temp controls. Which LED systems do you like? I didn't think the LED lighting light didn't carry too far into the night. I wish they made the t5 or t8 replacement LEDs in the reds and blues that would work wonderfully in there.
Stinkybudz I am not particularly handy so I don't think I could build my own.

[stinkybudz]

ive seen your catproof box which is impressive, i have cats too and boy i swear they always figure a way in :stoned:

You might do better with t5s or t8s in a greenhouse.
There are usable led arrays around but they are still quite expensive. My UFO knock-off was $220 but for a decent sized greenhouse you would want 3 of them.
Or 2 Procyons.
Much as I enjoy playing with leds personally, I'd advise waiting about a year before jumping in. Unless you are paying over 30 cents per KWH, that is.

We pay over fiddy cent here:mad:.

Stinkybudz I am not particularly handy so I don't think I could build my own.

If you can choose the glass for your greenhouse, see if you can find some "solar-glo", I think it's called.
Has corner reflectors molded into it that gather more sunlight than glass or flat plastic by gathering light from low angles and bending it to shine straight down.
Roofed a shed with it in the '80s and it worked a treat.
The shed looked brighter inside than outside because of the lensing and it colorshifted to the blue end also because of the plastic used.

Happy growin'
Weeze

Weezard, I value your opinion and think you are right I should stick with the fluros for now. Maybe I'll mount some onto the sides. I am not sure what the panels are made of but in the pictures they don't look smooth or clear.
Stinkybudz, My boys do love their greens. This new GH will be cat proof It has the hard plastic panels. I am so excited.

I work for this company: ProSource Worldwide (http://www.prosourceworldwide.com/)

We offer a 90-day no-risk trial on all our LED lights and a 3-year warranty.

We are also offering a deal like no one else: LED Grow Light Challenge (http://www.prosourceworldwide.com/category_s/51.htm)

I would have posted this here even if I didn't work for them. I was a customer before I was an employee and the lights kick ass. ;)

But, I don't want you guys to think I'm a spammer, either. I'm not.

This is the second time in less then a week I've seen your site mentioned.

I've looked at the site and it is just full of marketing BS. Your claims are wildly exaggerated...both in how much area they will cover and what size HPS they will replace, and that is thru out your product line.

Plus things like "sunburst orange" LEDs are used for canabiniod production....
First, I have never seen sunburst orange listed in any LED mfg catalogs. There is orange and even hyper-orange, but no such thing as "sunburst orange", what are your sources for these diodes?
Second, can you point to some science (research papers or trials) that show sunburst orange is responsible for cannabiniod production?

All I see is marketing hype and bullshit.
As to your not being a spammer...well if it walks like a duck, quacks like a duck, it probably is a :spam3: duck.

[Michael420]

Heh... well, I can live with that. I just thought I'd put it out there. It's a "take it or leave it" kinda thing. I expect some folks to have your reaction. I expect more folks to have a more open mind, though. The average person will see the 90 day trial and see it for what is - and it's not just marketing hype.

So, whether you think LEDs are worth buying or not, you'll have to admit that we either have something - for real - or we're completely insane. If people don't think the lights work, we'll take a beating, won't we? So, we put our money where our mouth is and have real growers evaluate our product to show we are for real.

All I wanted to do is let y'all know about us. I did that. Now, the more adventurous will be interested and the more sensible will wait for the proof to come in. In a year, it will be common knowledge. But, for now, it sounds impossible. Because no one else has done it. Well, someone had to figure it out, eventually, right? Is it really so hard to believe that day has come?

[Michael420]

By the way, I thought maybe it would be helpful to shed some light on what's going on with manufacturing in China. First, there are many manufacturers there making the UFO models, not just one. These manufacturers vary wildly in both their manufacturing skill and business ethics.

For example, I'm sure most of you are aware that there are a lot of LEDs out there for $100 - $200. Have you wondered how that is possible, considering the cost of 1 watt LEDs? The answer is simple: the diodes are 0.45 watts, not 1. They look identical, though. You would need to measure their output to know the difference - or see their invoices.

I hope this helps explain what's happening in the market now. Diode prices have not gone down significantly and the newer diodes, which are closer to peak photosynthetic values, are in great demand. Some laws you can't break. The law of supply and demand is one of them. There is no free lunch is another.

Micheal420,
Well the truth be told, OldMac has already been growing with LED's for a couple of years. So Has Weezard. In fact there quite a few of us here, myself included, that have grown fat sticky stinky buds with LEDs. So we know that it's possible, but we also know what's gonna fly and what ain't.

1 watt LED's just don't cut it !!!!
They don't provide enough photo energy (measured in micro-moles).
They don't provide enough canopy penetration.
3 watt LED's begin to do the job.
5 watt LED's are better.
15 watt LED's are currently the best single emitter LED package that can be easily sourced.

So go back to your boss and tell him that he better get cracking because the products you taut as being cutting edge are sadly being left in the dust. We have better home made LED lights being made by the foks on this board than the stuff you are trying to hawk at inflated pricing. I'd rather have one of Weezard's 5 LED 75 watt lamps than your 90 watt UFO (how many LED's?), and both Procyon and TI Bloom blow your gear from here to the next galaxy.

M.P.

[Michael420]

Actually, we've found it's possible to overload particular processes with too much light. We're happy with what we have achieved with 180 watts and I think any fair assessment will prove what I'm saying.

I appreciate your responses and I understand your points of view. We are aware of the current state of technology of both large scale manufacturers and hobbyists. HID Hut, for example, has probably spent hundreds of thousands of dollars on R&D over the last few years, if not more. I won't add to the confusion, though, by interjecting any new ideas or arguments here. I don't think it would ever amount to anything more than disagreement without end. So, what's the point?

In any case, talking badly or disrespectfully about what anyone else is doing in this field is counterproductive, to be nice about it. But, it's all too common.

They say you should be the change you want to see in this world. I'd like a world with less bickering. Certainly, we can agree on that, right? ;)

[Michael420]

Here's a guy that switched to our new lights 6 days ago... LED grow 2009 (http://forum.grasscity.com/advanced-growing-techniques/379587-led-grow-2009-a-47.html)

Either it does a good job or not...

It should be fun to watch, either way.

[oldmac]

Micheal420,

Why don't you contact the boards administration and request to buy advertising space here?

:wtf:If you think you and your other shill entity is going to come to a board that I consider my communitiy and sell inferior chinese crap with a lot of marketing BS and lies, and not have me call you on it, you are mistaken.:mad:

BTW I not looking to debate or bicker with you, just going to continue to point out to the innocents here that you are marketing crap. See, real simple.

:D
