High! (im new here! )

I have been wondering if there could be strains that would give good yields under LED´s? Ive seen many get 10-20g´s per plant, but that just isnt enough for me to buy a 90w UFO and growing one or two plants inside my little closet (under 1 sq m)

So ive been wondering, what if there are strains that could give as much as 50 or maybe 100g´s a grow?(100g´s is maybe a shot in the dark with LEDs)

But i was thinking, LEDs light dont spread much, and dont go through leaves as much as HPS or sunlight..
So what if you use a strain with little leaves, so that you can aim the LEDs to give light to the whole plant(see picture<- )
I was thinking about autoflowering ruderalis plants.. Maybe Easy Ryder (Lowryder 2 x AK47)?
This plant is short(50-70cm) and has few leaves, that you could maybe cut away? (the sativa leaves)

Maybe throw in an CFL light, to give the whole plant some light, and maybe give it some light from some part of the spectrum that the LEDs dont give it? Maybe it´ll speed up the veg and grow period?

Anybody who knows of any strains that likes the LED lights better than others? Saw that High Times used Cali-O and got almost as good result as with a 400w HPS!

Peace, from Norway

Unless you want to spend a good deal of money getting started, go with HPS.

If you are set on LEDs, I work for a company that makes them. We recommend 45 - 50 watts per square foot. A 180 watt light costs $700. It will cover four square feet. That's a 2' x 2' area. Experienced, large-scale growers are averaging one gram per watt with our lights. So, you can get 180 grams out of a 2' x 2' area with a $700 light that will take over 11 years to wear out at 12/12. It's very cost-effective over time - especially when you take the heat out of the equation.

If you wanna know more, drop me a PM or click on the link in my sig.

Thanks for the link to the High Times article!

Michael, can you address this concern for us? Would this problem have anything to do with the LED beam angle? What beam angle does your company recommend for maximum canopy penetration? And what is the maximum penetration of your 180w LED, at an optimal distance from the canopy? Lastly, are your LEDs CSA certified? Thanks. RT

Michael:
No, I dont want a $700 LED light. I might buy a used UFO 90w, about $100.. I think it´ll be big enough for my little closet..

But the meaning of this thread was to gather information about strains that can grow good under LEDs, and to come with some ideas and discuss some methods that might work better when growing under LED light.

Some cannabis plants need less light, and will maybe be happy with the lightwaves from a LED light? What do you think?

Anyone that has tried lowryder strains? Easy Ryder?

We have been experimenting for over two years now. Obviously, I can't reveal much solid information about our lights and how they're built. However, I can tell you this: it takes a powerful light to make plants flower and fruit. The yield is directly related to lighting (and everything else, of course). Poor lighting = a poor yield.

Cannabis is cannabis. I am unaware of any strains that will produce good buds from low-intensity lighting. Maybe they exist. But, they would be big news. If you think Lowryders were revolutionary, a plant that buds in weak light would change everything.

Also, I have never seen a decent bud grown with a cheap LED. They are ok for vegging. But, forget about flowering with them. They don't work.

I must confess ignorance as to what a CSA certification is. So, I don't think we have such an item.

However, we do have something no one else has: a 90-day satisfaction guarantee on our lights and a 3-year warranty. We find that talks a lot louder than statistics, figures and empty promises.

Okay. Just click on the following "CSA International" link, and it'll take you to their website:

"Choose CSA International when certifying your products that are being sold in the U.S., Canada or International markets.

"Selling your products in the U.S., or Canada is made easier when you choose CSA International. You're selecting a mark that is widely recognized by Retailers and Regulatory Authorities across North America. Our mark appears on over one billion products worldwide, and that number continues to grow. Click here for a listing of Retailers, Manufacturers and Regulatory Authorities who accept CSA Marks.

"Whether you manufacture, sell or specify electrical, electronics (including IT/AV, and medical), industrial products and components, (including products for hazardous locations), gas-fired products, HVAC equipment, plumbing products, personal protective equipment or a host of other products, CSA International has the mark your qualified product or component needs!

"We test and certify products to applicable safety or performance standards including ANSI, ASME, ASTM, ASSE, CSA, NSF, UL and others."

I can certainly appreciate that. A 90-Day satisfaction guarantee does wonders to boost consumer confidence in the product, but I still want to know the specs, regardless.

Now, which is the best beam angle for maximum canopy penetration?

Secondly, what is your standard LED beam angle, or do you offer a selection of angles?

Thirdly, what is the maximum canopy penetration of a 180W unit, at the optimal distance or height from the 2'x2' canopy?

Fourthly, what is the total lumens of your standard 180w LED? And what would the total lumens be for the same unit but with a 30 degree beam angle?

Now, no information on the specs details ultimately defeats the purpose of the cool satisfaction guarantee. Convince me I'm buying the best light and I may take advantage of your guarantee. - RT

We don't reveal specs, at all. That policy isn't flexible, I'm afraid.

We recommend the 180 be kept at 6" to 12" from flowering plants. You can go a lot farther, with a larger footprint, for veg, though.

Penetration is pretty good. It's hard to quantify. But, the inverse square law - or a slightly skewed version of it - is still in effect.

Here's a link to a large grow with 10 - 180s: Growing with the 180W Jumbo UFO

Seeing is believing.

(That same guy will be getting 48 more 180s. I think he's a fan. )

No, I have'nt tried those strains, nor do I plan to in the future. However, if I'm not mistaken, there are indoor strains that have been specifically bred to perform well under low-lighting conditions. Northern Lights #5 is a classic example of that kind of breeding. Indoor sativa dominant hybrids are another example of strains that have been specifically bred to perform relatively well under low-lighting, seeing that most indoor set-ups are low in lumens by any comparison to the great outdoors.

However, if I am not mistaken, Michael's first reply seems to be saying that the best LED will grow anything that the best HPS will grow, and better, if you have the right equipment dialed in properly. If that is true, as I suspect it is, then the question of which strains peform best under LED remains basically the same, essentially, I should think, as to which strains perform best indoors, versus outdoors.

Assuming that Michael is correct, in terms of the qualitative differences that exist among LED grow lights, then the real question I think we need to ask is how can we identify the best LED grow light currently on the market? That is, in part, what my last reply to Michael is hinting at. Though steep, the price does not so greatly deterent me as not knowing for sure that I am getting every penny's worth in the best LED technology available, at the best price. - RT

Well, the only response I can give you is sort of a broken record thing... no other LED manufacturer offers any sort of satisfaction guarantee, at all, let alone 90 days.

So far, we have sold hundreds and hundreds of 180s and not a single unit has ever been returned - not even one.

By the way, I'm happy to answer whatever questions I can. But, I'm not a salesperson. If you really wanna know what's up, call Doug at 866-921-5553. That's a toll-free number. Call anytime between 9am and 9pm, Mon thru Sat, EST. I'm sure he'd love to hear from you.

Yes, seeing is believing, so I'll wait for the results of Rosenthal's test results of Hydro-girl's gear (see Post #84 of the thread you linked for us, in which she makes the following remark: "Sure their 180W may work, but time will prove to you that they don't work anywhere near as good as my cheaper, better designed, full disclosure units. A real lighting company doesn't hide their specifications from the consumer."

Hydro-girl has some balls, admittedly, but I prefer a "full disclosure" policy; and if her gear grows the bigger, tighter colas, guess who's I'll be buying? She's already way out in front of you just on the basis of policies alone. I have no conection to her, nor do I even know her, but she gives me the clear impression that she's got nothing to hide. Thank you for the link, nonetheless! - RT

The repetition of Post 14 can be explained by the fact that I thought Post 13 was lost to a technical glitch. Had I realized it was put on hold for a moderator to approve, then Post 14 would have looked entirely different than it now does. - Rt

No sweat.

It seems that the forum likes to randomly do that, despite the settings in the admin control panel. I'd say we have a wee bug.

Anyway, what about the CSA Certification? Do your LEDs come with any comparable type of certification? - RT

I haven't posted in that thread, at all. I'm not punjammer. He's a friend of a major grower who isn't interested in posting on forums.

Other than that, I don't engage what's-her-name on any level. She isn't rational. There is no way to deal with irrational people. You just tune them out and go on about your business, hoping they fixate on something else.

Whatever choice you make, I wish you the best. But, I wouldn't buy a dollar from her for a dime.

Canadian Standards Approval? Why would they need that for an American made product? ASA most likely....will cover similiar tests.

We're CE & ROHS compliant - whatever that means - and our lights come in either US or European voltages. We sell them all over the world. But, I really don't know about anything highly technical. I'm not an engineer.

My apologies for the mistaken identity. I don`t know how that happened. Sometimes I don`t read very carefully, and make stupid mistakes.

If Hydro-girl is as bad as you say, I can`t see Rosenthal working with her, or wanting to pump her company. I have a hard time believing he`s that bad a judge of character.

Anyway, appearances are deceiving. She did seem a little edgey in her postings, and maybe even a little irrational in terms of her temperment, but I did not see anything irrational about her business policies.

To be perfectly honest about it, I was literally fantasizing most of the night about getting three of your 180w units, but your non-disclosure policy cooled my jets. And then learning about her gear. Well, I`m not sure what I`ll do, other than the fact that I intend to have the best LED(s) money can buy, within reason, of course, for the best possible price. - RT

Sounds like you know her well...

Just because she says she's working with Ed Rosenthal doesn't make it so. She and her alter egos say a lot. But, if she told me the sky was blue, I'd need to take a look out the window.
