A few people have asked me recently why I don't post a lot of pictures from my own garden online, and the honest answer is simply that I didn't have much to show up until now. I went on a trip to Mexico in September, and during that time a lot of my plants stressed out, so I chopped a lot of them early, and left some of the scragglers that were in better condition, alone in 1 tray. It took us a couple of weeks to get some more plants ready to fill up the bloom room, and now I welcome you to see what I do personally with LED's.

First and foremost, I am a legal medical patient, within my legal guidelines for plant #, etc..., and this is my personal garden. I don't support breaking the law, or the illegal growing of marijuana.

Here's some information on my garden:

Each plant veges for about 4-5 weeks prior to entering the bloom room. During that time, they are usually topped about 3x, causing the plants to grow into super-thick little bushes with lots of tops. Once they reach 18" height, they transfer to bloom.

The bloom room operates at 85-90 degrees during the "day" cycle, and 65-70 degrees during the "night cycle. The humidity remains between 60-75%. There is a wall-mounted fan on each side of the room for good air movement, and of of course a carbon filter. My bloom room is a sealed environment, with CO2 levels at a constant 1500ppm via a fuzzy-logic controller. Since I use aeroponics, the nutrient solution is run through a water chiller, which maintains it at a constant 67-72 degrees. There is also a micro-pore air diffuser, and a commercial air pump constantly supplying oxygen to the solution.

In my bloom room are two 2' x 4' x 1' Aeroponics trays that our company manufactures. At full capacity, I run 8 plants per tray. Hanging over each tray, are six 126W LED Grow Lights that we also developed (as most of you know). So that's 756W over 8 plants x 2. The total room measures 9' x 8', with an 8' ceiling, and is lined in 97% reflective mylar (from the HID days). The canopy space measures approximately 5' x 6'.

I feed my girls Advanced Nutrients, Iguana Juice Bloom, and Dr. Hornby's Big Bud (not the current crap advanced makes since they split with Hornby). I run no other supplements currently in bloom. The nutrients are added per the manufacturer's recommendations for heavy feeding, and the reservoir is topped off with water mid-way through the week. Nutrients are changed out weekly when the system gets cleaned.

The current strains you'll see in these photographs are: Strawberry Cough X White Rhino, Ice, Grape Ape, Maui Wowie, AK47, Purple Arrow, Sensi Star, and Afghani X Brazilian Skunk. These plants will be replaced in a few months by Pineapple Express, Barney's LSD, Yumbolt 47, LA Confidential, Alaskan Ice, and A-Train.

Anyhow, these pictures were taken 10-14-09, Enjoy!:

Holy crap that looks good. Is there a big difference between LED and HPS yields?

Previously I ran 4, 1000W HID (2 HPS, 2 MH) over the same sized canopy. My current yield using 1512W LED is more than what I did previously with my HID's, and it's better quality. My buds are also 30-40% denser on average, with all environmental factors being the same. There is no heat stress to contend with, so I've also found that it's easier to remain consistent from harvest to harvest, using LED.

That is some enlightening information. Why do you think that so little people use LED systems to grow with?

There are lots of companies making LED Grow Lights, and each of them is responsible for developing their own technology. Up until now, if you look at other LED Grow tests online, you will see that they usually under perform by a lot. For example, companies like to state that a 90W UFO can match a 400W HID, yet when it comes to yield they fall way short (luck to get half of a 400W HID), with small buds.

Ours are the only of their kind, when you see the kind of results we are posting with LED. No other company has mastered the technology yet to the level that we have been able to. We also developed our lights specifically for marijuana, as I'm a medical patient and am constantly seeking out new ways to improve my garden. So the results you see with our lights, will not be seen on other LED grow journals (unless of course they're using our lights lol).

I'm the first company to introduce LED results that are truly comparable to HID results, using far less wattage. My results have been posted all over the web, and my customers are testing out units on multiple various forums as well. Once there are a lot more grow journals in completion, you will begin to see a huge market shift to LED lighting. We've sent free units out to S_a_H in the AutoFlower section, Sleepy in Grow Journals, MrWags in Organic, and Benji. They should all be starting demonstrations in the upcoming weeks that will show more of the same: awesome results using less power ;)

This is simply my personal garden, to show you what one "advanced" medical patient can do. Not everyone will be able to duplicate my results (as my garden is quite technical), but a lot of people will strive for them. Hope you enjoy the show! I'll probably post update photos once per week.

I hope LEDGirl doesn't mind me chiming in here. My :2cents: on why people don't use LEDs is that they haven't really worked. For most growers LEDs are a novelty because so many companies peddle so many pure BS products in the field. Now, having said that, I can't say that I have seen many grow journals here or elsewhere in the mj community that utilized LEDs and ended up producing up to par. I hope that the current round of test grows using LEDGirl's lights are more productive because it would be a great step forward for closet growers all over the US that continually struggle with temperatures. I can't say that I can really see these being a viable option for large scale growers but you never know. If they do work as well as she claims perhaps they can be viable but only time and the corresponding results from the test grows will tell.

Edit: Oh and LEDGirl, do you mind taking some pics of the hardware you are working with in your aero tables? Or maybe even some root porn? :)

sweeeeet grow LEDGirl! What a crazy mix of strains. :joint::rasta:

Thanks for sharing! Def been curious about LED growing, and have friends that are curious as well.

Looking forward to more pics!:smoweed:
 
also a lot of people are hesitant toward going LED for the same reason I am...$$$$$ the cost of the units is sometimes double or more... LEDGirl's products are wuite fairly priced IMO for the results she is producing and will be more that happy to graba few when the $$$ sitch is better...PS.. Excellent garden... some of the pics specifically prove the penetration your getting...awesome...PS if you wanted to send me one I promise i wouldn't object...lol i am an apartment grower so the heat and electric usage problems being eliminated like that would be amazing... enjoy your beautiful fruits!!!

While I certainly respect your opinion, I'll go ahead and share my personal experience. Regardless of how much HID I was running at any given time (2k, 3k, 4k), I encountered lots of problems with heat (like when your daughter trips over the A/C cord). At times the A/C unit's storage tank would fill while I was at work, and I'd come home to a 100 degree room with wilted plants. Other times I'd leave for a week and my friend would forget to monitor 1 aspect of the room (water, heat, etc...), and I'd come home to half the garden I left. There were probably about 5-7 total cycles in the course of 4 years where I had a solid harvest which endured little to no stress. Consistency isn't the easiest thing to achieve for a learning gardener, when you're facing heat all the time, and it can make a big impact on your total yield. On a really good harvest, I'd hit 1 gram per watt or relatively close with my HID's, but I think if you averaged out all of my harvests, it would probably be around .7 grams per watt.

My recent switch was from 4,000W HID to 1512W LED. The retail on my 4,000W setup (digital ballasts, vented hoods, hortilux bulbs), was about $2200. The ventilation system was another $200, and the A/C was an additional $500. So all in all I dropped $2900 for my HID's, and was running about 5500W for the entire system.

The retail on my 12, 126W units (1512W LED) is $4800 shipped; a difference of $1900. I don't run A/C (except intermittently during the summer), and the noisy ventilation system is history. Each of my 126W lights really draws about 144W, as they have 6 small fans on them. 144W x 12 = 1728W. So every hour I am using approximately 3800W less.

That 3800W equates to about $160 on my electricity bill every month in savings. $160 x 12 = $1920 savings per year! That alone covers the cost difference between the two lighting systems. On top of the electricity savings, there are no bulbs to replace! My Hortilux Super HPS and Blue MH bulbs cost about $700 per year. So within my first year of using LED, I will actually save $700 over a comparable HID setup with all the necessary add-ons.

LED's last for 50,000 hours before they lose 30% of their total output, and 15,000 hours before they lose 10%. At 15,000 hours, that's 4 solid years in your bloom room before your light is at 90% of it's original output! Realistically though, they will last 6+ years in veg, and 10+ years in bloom.

So to sum it up, I save $700 this year, $2600 next year, $2600 the year after, and $2600 the year after that, just for switching to LED. On top of it all, my yields are more consistent now, the heat stress issue is no longer an issue, and my yield is also higher quality. So in my opinion, LED can save gardens of any size, a lot of money.

Edit: Oh and LEDGirl, do you mind taking some pics of the hardware you are working with in your aero tables? Or maybe even some root porn? :)

They measure 2' wide, 4' long, 1' deep. Keep that in mind when looking at the roots ;)

Any specific reason you hang the lights on the ends at a slight angle:chin:?

The same reason you would supply side or supplemental lighting. If I was running 3 rows over each tray, I'd have light on the outside shining in as well. Having light coming from multiply angled sources, allows for better penetration. Having light that hits the side of your plants, also allows for thicker buds all the way down it. I tend direct all of my light at the plants so none of it is wasted ;)

hmmmm......i dont know about this.

a couple of replies after this quote, you say you averaged .7 grams per watt with your hid's. .7 *4000w = 2800 grams \ 454 = 6.16 lb's. right?

you say you yield more now with led's. lets say to be safe with 7 lb's. your saying you yield 7+ lb's with 1512 watts of led?

i bet you sell these led lights, dont you?

To answer your final question, YES I DO, and I also developed the lights as I stated in my first post. I'm sure you've seen my banner flashing across the top of the forum pages... Hydro-Grow-LED

My last harvest with stressed plants averaged between 1.55 grams and 1.85 grams per watt depending on strain. With my current plants, I should hit 2 grams per watt, maybe a bit higher. 2 of my customers have reported 2 grams per watt with these lights, so I know it's achievable.

So, 1512W x 1.85 ~ 2800 grams. 1512W x 2.0 ~ 3000 grams. And yes, you heard me right, that's 6+ pounds with 1512W LED. If you go to the "LED Grow Lights" forum in the vendor section, you can see where one of my customers did just over a pound on a single plant under 252W LED.

Mr-B

My goal is not to argue, it was simply to point out that I did in fact run 4, 1000W HID's over a 5' x 6' area, so no one can call it questionable any more. You never said my lights aren't capable, nor did you say anything negative towards them, you simply stated that you found certain information that I posted online, hard to believe so I posted evidence. I thank you for purchasing one of our units, and am glad that you are giving LED a shot. It shows you're not closed minded like a lot of people. Anyhow, sorry if there was any confusion.

Thank you for the post.
Looking back at my original post it did seem rather crass and I didn't mean for it to sound as if I was knocking the unit.
That fact is, my unit is suppose to arrive this week sometime and I plan on using it for my veg area.
I didn't get the jumbo light as I didn't need it but, I'm watching everyones grow hoping everything turns out positive for all.

I really was hoping this thread didn't turn out similar to the one were talking about. It just seems that whenever you get people with opposing opinions everything go's wrong.
I purchased your light two weeks after you became a vendor here, I really wish you all the best.

peace,

B

Forget it... it will just get deleted anyway.

LED, I'm not trying to be rude. I would really like to see LED grow lights succeed. But if you make claims as specific as the ones you have made, expect skepticism and doubt, and be prepared to back it up.

Until the day that somebody does a side by side 400W HPS grow vs 126W LED grow, these questions will remain. All I suggest is that you lose the comparison to HID lighting on your site until that claim has been thoroughly vetted. I'm neither presuming that it is correct or incorrect at this point. But there should be a burden of proof for ANY vendor making ANY claim that specific.

I'm sorry please accept my apologizes, I hope everything works out for you. But I do have question if I were to replace my HID 400w+600w with one of your 318w equivalent to 1000 watt Hps and according to your specifications Use within 6 – 12″ from your canopy for best results seems like I would need maybe 2 of these or more to get maximum coverage and penetration and at $1175 a piece and 40 pounds each that's alot of weight and cost. I guess I could possibly used 4 126w.

Approximate Coverage Area of 2′ x 4′ at 12″ above your Canopy

Like I said I will wait for the data on these testers.

I say she's a witch! If she's a witch she won't burn when we throw her into the fire. Throw her into the fire! Throw her into the fire!

O my, look at her, burnt to a crisp... guess she wasn't a witch.
