hey bud. I'm not biting your ass here, but we all know you can grow an excellent crop under a 1000W MH. I really dont know what the price of a 5W LED is but I would imagine they're fairly expensive. Just out of curiosity, do you know what one 5W LED for growing costs? I cant find any 5W growing LED's on the net, I'm just curious, not chewing your ass or trying to piss you off.
To replace a 1000W HPS with 5W LED's as far as power output goes you would need 200 5W LED's. Now, being conservative, let's say one of those LED's is 20 bucks apiece for a grand total of 4000$ plus tax (4520.00$ here in Ontario, I believe.) even at 10$ per LED, you're looking at 2260$ without the circuit boards, mounts, power cords and whatever kind of casing you're going to fashion for the lights which would include the use of metal shears, perhaps a brake for bending, something to deburr the edges, a ballast of some sort because you cant run 1000Watts off of one circuit and whatever else you may need to fashion you lights. All of these things would take some time to accomplish and I don't think too many of us have all these tools sitting in our garages. You would have to spend most of a day just soldering all 200 bulbs onto the board/boards for example. Thats a hell of alot more money than a 90-130$ MH that puts 1000W. On top of that, I dont think there would be any power consumption bonus. 1000W is 1000W. Now, you would be blessed with a longer life span as far as the LED's go and a more accurate light spectrum for growing.
If my experiment doesn't work, oh well. I'll try again, at least I'll have the benefit of some experience by then. I didn't buy these lights because I thought they were a sure fire method of growing anything. I've seen some pretty impressive pics of a variety of different plants grown under these lights including a 7' tomato plant with some real nice tomatoes on it. I thought it would be a fun thing to try.
I'm also new to running an aeroponic system, so I'll probably make more mistakes as far as thats concerned, but I will learn from them and not make them twice. If I had to spend a couple thousand on lights, I don't think this would be for fun, or curiosity. Now that would be some serious shit and a huge investment. We're on here to try and find more cheaper and effective methods of growing, and advise when we need it. I'm just going to have fun with this.
Yes mate its ok i know how it can seem that people are knocking you but thats not my intention or how i wanted it to come across.
I only have a 400watt lamp and i was seriously looking at leds in the past but the best kind,5watt wide angle high power leds as you say are very very expensive.
I have looked into my own led growing and making them myself and found it to be a bad business decision based on investment to final bud weight.
I have watched many led grows and none were good.
Having said that no grow that i have watched has used as many leds as you are so i really do wish you the best of luck with it and if you pull it off you will have a lot of respect from people including me.
Here is the led site that i use and did all of my research at previously.
These were the only leds that i could confidently say that if made into an array and housed in mini reflectors could compete with hids in terms of investment to weight ratios.
They are about 20 dollars each though so as you said before very expensive still for the minute
