OK my head is spinning from this thread. Can someone recommend a decent LED for my chamber? It's a small cabinet, and I am mainly looking at LED for two reasons, listed in order of importance: heat management and density. Right now I am using CFLs, and even after adding an extra exhaust, my temps are too high. Mainly my guess is because the boxes are in a closet, and the air in that closet is becoming to warm.

Anyhow, chamber size I want to implement this in is: 34 3/4in tall x 24in wide x 15 1/4in deep. Those are exterior dimensions. Take about 1inch (at most) off all around for interior dimensions. I was thinking a Blackstar or something in that range, but I am thinking that may be too much for the small chamber. I am LSTing my plants, as well.

I have the Blackdog BD220 and love it really good customer service
Hope that helps ACT draw 200+ watts 15 spectrum including UV
I've been looking at the Blackdog line to possibly add to my current setup, particularly interested in the same model. Great to hear you're happy with it. What size is your grow space and how many plants do you fit under it?

What kind of warranty does Blackdog have for their products?
3 year warranty Great customer service as well
UPS scewed up took 13 days from time it shipped and Corry refunded the shipping no questions asked,told me it wasnt my fault and I shouldnt have to wait for the refund from them or wait for my lights:clap:

running them in my 3'x4' cab I had a 400w HPS just to see how they worked so far Great

just bought my 4th blackstar unit 2 days ago.... these are boss and your a hater because of the difference in price point.... I have an awesome grow going atm with nothing but blackstar leds and the ladies are EMERALD GREEN. Fuck the haters on this site......
You got 98.8 grams from two 240 Blackstars on your last grow right?

dunit if you get more grams per watt than tshirtninja that in know way means the magnums are better than blackstars....it simply means you got more grams per watt than he did....to many other factors besides led brand and dry weight of bud

if i were to believe what your implying then you should have no more or no less than 327grams on your second grow because your still using two 357's as you did on your first grow........but we all know that isnt true

While I agree that comparisons of grams/watt should be taken with a grain of salt I do think that, as it stands, it is the only quantifiable measurement that we as consumers can use to make decisions on the efficacy of a light. We all know that many of these LEDs can grow great MJ, isn't it a good thing that over the course of each successful harvest we can accrue data as to how effective each light may or may not be?

It would be far more accurate (and not difficult to calculate) to go by grams per kilo/watt hour. G per W is too simple, but in a way it can work (there is only soo much bud an amount of light can support). Theres only so much yield one can get with say a 400w HID vs a 1000w HID, but since both can grow the same amount of stuff under the right schedule you must also include hours not just g/w

I said this in another thread and I stand by it, it is just too long to reiterate:

"Next issue: why I mix LED and HID: Cuz its better. Why the hell would I settle for low weight pulls just to say I got 1 gram per watt when I am only using a couple hundred watts of electricity. Shit, I am still a novice by all definitions, this is a hobby, not a career for me, and I burned the hell out of my plants last grow, barely kept them alive after that, and still pulled more than dunit out of 10 plants. (16.2 zips - BONE DRY AND CURED 16% RH in the jars).

Dunit has done this for a long time, he knows more than I do, and he will kick the shit out of me when it comes to g/watt. However, anyone who is buying my weed just cares about the weight, not the electrical efficiency. The bump up in weight you get by mixing LED and HID far outweighs the electrical difference in cost. Let alone the horrible difference in price between the blackstars and magnums.

If anyone looked into all the threads I started, (as clearly I am being checked up upon) you will see I had a LED and HID side by side grow. THe temps for the HID were 80 degrees, the temps for the LED were 61. Needless to say the HID kicked the shit out of the LED just based on the difference in the plants metabolism.

Lets put things in perspective, most growers are doing this as a hobby and don't have the need or want to purchase multiple 700 dollars LED units as most of the "Featured Grows" have had. Also most people don't have elaborate hydro setups or CO2 monitors. Most people don't have the interest in throwing thousands of dollars into a grow setup. Especially when throwing a couple of hundred will get a bitching HID setup that will dollar for dollar (not watt for watt) kick the shit out of LEDs.

Lets look into this further: If ledbudguy used 6 (or what ever number of ISIS units he had) 400W units instead of the 170W LED's he would have walked away with several pounds. Dude had CO2, great nutes, and an entire attic, and 24 plants. What did he say he had 26 zips? That probably dried a ways below that in curing, but I'll take him at his word. Still, lets assume he got a good deal on the ISIS units (especially as I suspect he has a certain relationship with the company) and he got them for 300 each. Thats 1800 bucks. 200 bucks gets a real nice HID, so the lights would have cost 1200 instead. Right there he saves 600 bucks. (yeah I know, replacement bulbs ect. ect. ect...Im just looking at start up costs) He would be using 2.4KwH using roughly (assuming at 30 day veg (1296 Kw) and a 60 day flower (1728 Kw)) 3024 Kw total lighting for the grow with HID. Lets add 200 KW for ventilation (which is generous). 3224Kw total electrical consumption. At 15 cents a Kwh that works out to: $483.60 electrical cost for the grow. It would be horrible if he didn't pull at least 2 pounds from the grow, especially with the CO2 going on. 2 pounds, assuming he is letting go in zips or QP (at 100 a zip - (low for some high or some) = 3200 bucks. 3200 less 1200 for the lights, less 484 for the electric (all other costs are identical between the two grows), that leaves 1516 after covering all mentioned start up costs.

For LED, like we said, he probably spent 1800 on the lights, the 170's draw 120 (as stated from the company in an email I sent to them) Veg = 388 Kw, Flower = 518 Kw = 906 total KW's for the grow. At .15 per KwH that comes out to: 136.02. So lets look at the math: 26 zips at 100 a zip = 2600 less 1800, less 136.02 for the electrical. = 664 left over.

Hrmm, amazing he pulled .9 g/watt but who gives a shit? Those fancy dancy panels don't pull a damn breath over HID if they wanted too. Even the best grower, under the best set up (Light movers, CO2, Hydroponic with monitors, ect...) wouldn't be able to compete with the identical set up with HID's.

Let's not mistake ourselves however: LED's offer the abundance of UV that HPS doesn't (especially if there is protective glass in the hood), It has fantastic spectrum targets, and is very very efficient. Hence why I mixed both HID and LED. I needed more lights, did some research, bought LED's, apparently I didn't plan well enough to account for temp differences, tried growing with just the LED's, went fine but slow due to temp, mixed the two and boom, great quality weed at pretty great newbie numbers coming in.
LED's allowed me to supplement my HID's perfectly. They are the perfect supplement. They work just fine for stand alone as well, but you loose grams/grow room and trade that for grams/watt.

Blackstars work fine, there are plenty of grow journals on this forum that I read, and many others on other forums. When I was buying LED's, I noticed that there were hardly ANY LED grow journals from any company went to completion. I saw a couple of blackstar grows and they were just as fine as any other of the journals. Boom, bought some blackstars when I went back east for thanksgiving.

If the search funtion on this forum was a bit more pointed I'd be able to pull out more of them. Im not anyones secretary, search yourself. Heres a good idea however:
If a product sucks on this site, it tends to get shit on by users of that product. Find me a journal by a Blackstar user that isn't satisfied.

In regards to Nickyp....He doesn't have a huge grow op (thats fine, neither do I), he doesn't have a shit load of fancy equipment, I have no idea how experienced he is, but I am willing to wager that he is not on the level of Dunit, Ledbudguy, and dude from Ireland. (again many people aren't). He's looking for another light, dollar per dollar no one is cheaper than blackstar (both on advertised wattage and actual draw) and all the right spectra are there along with the intensity.

Tell me why a grower who only stands to gain a limited amount per grow should go out and spend hundreds of bucks on a "premium" LED grow panel. Honestly I should have told him to cop a 250W HID and an extra fan and he would be really set up by mixing both lighting sources. Fantastic bud at fantastic weights.

Again, I am sorry I don't just use LED, and I don't pass the purity test, however I am trying to grow weed, not a reputation, that means growing weight, not raw efficiency. The day I can go up to some one and convince them to pay me 50% more for weed cuz I used less electricity then I will go all LED, until then, the day I get 26 ounces from 24 plants is the day I quit growing. CFL grows can get more than 1 zip per plant for christ sake. Shit my first grow was 2 zips per plant. Fuck, at that rate Ledbudguy would be looking at 48 zips.

I just hate seeing people compare everything to 3 growers, and not looking at the grows in full context.
First off, I don't even follow the Irish dude, he is totally on a different level than most growers, myself included.
Secondly, Dunit is probably the most tolerant person I have seen in the trench warfare of LED arguments and I have to apologize to him if anything I am saying is reflecting upon him
Thirdly, everyone uses LEDbudguy as a yardstick for the industry. His grows are atypical and his weigh ins are great from the lens of electrical efficiency, however in the lens of cost efficiency, hes horrible (as proven above). His entire argument can be broken down to: "I save money on electricity by growing less pot". Well, myself, I make money off of mine, and I keep some. I assume most people are in the same boat in this field. Either medicinally or otherwise.

Again, please prove me wrong about any of my points. Thats enough typing on this thread, this has been an abomination for Nickyp and I have been the core of it. If anyone want to continue this back and forth, please post on the thread in my sig, I'll gladly host this debate."

Great read. If I were one to grow to sell I would probably go with blackstar to get as much light for the $ as possible, but its just my patient and I so... went with the luxury/expensive one

PS: watch out peeps, bean plant be getting light burn at 2ft from 395w LED, but the cannabis seems happy. Definitely not a temp thing as you can only feel warmth of LED 2-3in. from glass (which is barely warm), and ambient is low 70s. So yeah, be careful with... simpler plants under LED ?


PS: Ok I now realize the reason why my baby ice plants were growing soo slowly. The inter nodes are about as close together as possible, they were growing soo slowly because they were growing new tips and those little tiny blade of grass looking bits while hardly growing in size. I never noticed because all this was under the 2-3 sets of leaves they had on top that were covering up what was going on below. The plants are growing slowly because they have soo much light they don't know what to do with, so they do everything and once and thus only have a couple pairs of leaves from growing too many new bits at once. Haha two of the plants are doing fine though because they had 10-14 days under CFL in a PC grow box so they had a chance to grow a couple small sets of leaves before going under LED, unlike the others which have been growing new tips as fast as possible (and thus are still very small plants over all)

Led grows aren't just about cost efficiency. New report show that indoor pot grows use 1% of the total energy consumption for the entire country that's 7 power plants just for bud. And 2 pounds of c02 per joint! Led grows can help bring down those numbers, and help forward the tech that will be lighting all our homes in five years.

Hudson.....no offense taken. You always make great points and provide realistic expectations and honest information. I didn't know I was being compared to Irish and LBG and seeing as how I only have one completed grow and screwed it up with nute issues perhaps people need to find someone else :)

I often end up in arguments pertaining to Blackstar but it is ONLY a reaction to people who claim they are the best and I don't think that is fair to the people looking for honest information. I have never claimed my LED's were the best and the only grow I have completed (and screwed up with nute issues) still produced better than any Blackstar grow for grams per watt and it wasn't because I grew that well.

That being said there is nothing in the price range other than HID to compete with Blackstar so if that's the budget you have to work with I would definately recommend any grower get them over HID purely from a detection and safety standpoint. They will definately produce some decent smoke and you won't be dissapointed. If you have more money for startup and are in this for the long haul I think there are other lights that produce better yeilds and thus be more profitable even if they cost more to begin with.

So back to your points:
If you consider startup costs only....LED makes no sense. Also, in terms of the ability of a light to produce weight in a fixed space....I think HID wins that fight every time. I've known people who get 2.25 pounds from a 4x4 area. I think if I get this dialed I will pull 1.4-1.5 in a 4x4 (I might be dreaming too) so no contest there.

On LBG's grow. It was a confined space. He doesn't have an entire attic. He has the end gable in a house. It's 4 ft wide. 3 ft high and 14 ft long. One of the walls on the long sides is at a 45 degree angle so the 4 ft wide reduces to 1 ft wide at the max height of 3 ft. He needs room to crawl down the side of his grow so his actual growing area is 2 ft wide, 3 ft high and he has a carbon filter at one end and his co2 at the other so the actual growing length is 12ft. In other words he has very limited height and 24 sq ft.

Basically he's growing the equivalent of a 5x5 area and has 30" from the floor to the bottom of his lights. First off you couldn't use HPS in that area without starting a fire because they'd be jammed into the corner of the ceiling. But lets say you could use two 400's. You'd still need 8" off the lights for the plants and with 8" for pots (stubbys) you could have 14" plants. So two 400's over 14" plants in a 4x4 area. I really don't think they'd pull 26 zips and I'd be surprised if they broke a pound. To your point of this being about the money, I agree. Grams per watt in the end is dollars per watt because even if you grow your own, if you didn't you'd have to buy it. Anyway, he couldn't grow with HPS in that area so LED is the money in that space.

So back to the money discussion. The startup cost sucks but I really think that LED has commercial merit and that's what I'm hoping to prove in the next couple grows. The commercial guys I used to know never grew anywhere for more than a year as detection was inevitable. Once a year they had complete construction costs at a new location. That's not cheap and it also wastes time which is money.

For those trying to run the biggest show they can under the radar:
Where I am it is generally accepted that you can get away with a four light show or a three light show with A/C. The A/C route is preferable as it allows for co2 and sealed environment avoiding odor and humidity detection issues which are big when you are trying to vent hot, humid air in sub zero temperatures. Either way the limit is 4000 watts. That's where LED has great commercial viability as LED has the highest grams per watt so basically it grows the most weed and thus is the most profitable.

Now to your point which is very valid and is probably the category MOST PEOPLE ON THIS FORUM FALL INTO. If you are growing in a 4x4 or 4x8 area then HID is the cheapest to start up and will produce the most bud in that space so in the end it's the best bang for the buck and most profitable. HID produce so much light that when LED are added they become supplemental lighting so at that point just buy the cheapest LED's you can as their contribution is minimal anyway.

Cheers!

in a 4x4 or 4x8 area then HID is the cheapest to start up and will produce the most bud in that space
LED will produce more than HID in that space if you give it equal wattage (though you can often get away with less). I think the only way you could really grow more with HID than LED watt for watt is is you are growing plants all around the bulb instead of from just one side of it (you can get LED closer and its more evenly spread/reflected than HID and more efficient etc, no reason LED can't grow as much in that space)

But you're sure right that HID is the way to go if you don't want to spend tons up front

hi guys im on my first grow with a 120w led and happy with the growth so far seems to be a rather dense plant so i moved light away to try stretch her so i can get mor penetration when it comes to budding

also I plan on getting a new Led in the future to give me higher yields

im thinking 3w chips with 90degree lens and 360ws of power
but i need help picking the ratio of the chips and also if i should use different brands for different chips
the wavelengths im looking at are 430-440,450-460,625-630, 640-660,730,590 and white 6400 and 2700k
any one able to help if you want more info https://www.rollitup.org/grow-room-design-setup/426614-what-spectrum-new-led-light.html
