Here are some more. From the same grower. In the pic with the two levels of plants, he says the plants are only a week apart.

In case it's not obvious, this guy knows his stuff. He's one of the guys that tried one light and bought a bunch more after a cycle.

THAT is what I was talking about Michael! AWESOME!!!! Nice ripe bud there buddy!

I am sure with all those plants the yeild will be well above what my poor little hid can do. They all look so even and none of them need to be rearranged to get the light like mine do. These look earlier.....I would love to see these as they grow! Very pretty and even growth....the problem with HID is that you must maintain that distance. Doesn't look like those babies will have any trouble getting to the light....

WONDERFUL! And I bet his electric bill is a lot less than mine.....way to grow!

I'll be getting updates weekly.

Hi Michael I noticed in the first pic there are 8 lights being used here. Do you know what the wattage is and the size of the room they're in?

__________________

Those are 180 watts.

We figure 40w - 50w/sq ft is about perfect.

8 x 180 = 1440 total watts in a 6X6 room

8 x $699 = $5592.00 lights in that room? Yikes! Am I missing something in this equation? Not trying to be argumentative but trying to understand cost vs yield over potential hydro savings over years is all.

__________________

Add up the cost of bulbs... change 8-600 watt lights every two cycles. Then, add in the cost of cooling and ventilation.

These are warrantied for 50,000 hours. That's 11 years at 12/12. Do the math. If you have the upfront money, it's a huge money-saver.

8 600 watt lights would be able to cover 96 square feet, or almost 3 times the area of that room.

A more fair comparison would be 3 600s, which would cover a 36 square foot grow area much more effeciently than 8. 3 600s would cost about 2900 dollarsto both purchase, and operate over 2 years. The LED would be about 6500 at that point. The power cost would be almost identicle, but the LED would make up about 250-300 dollars every 1-2 years for bulb replacement. That's 10-20 years to even out, by my terrible and quite rough math.

Do you know what this grower is able to yield yet or is that still getting worked out?

Also, if you don't mind laying more upfront, you can get a box of 6 HID bulbs for about 75 a bulb, that's 225 a complete change out for 3 600s, not that bad if you do it once a year.

So I need 8 lights for my 6x7 area?

42 sq. ft. needs 2-1000's or 3- 600's or 5-400's, you'd like to get 50 watts of light per sq. for max. growth.

HPS bulbs are only good for two cycles. That's eight months. Many growers use as much as 1/2 watt to cool every watt of light. Then, there are fans and ducts and all that. Don't forget that the ballasts wear out, too. It all adds up.

These lights aren't for everyone. But, for many people, they are ideal.

Generally speaking, it's easy for the average grower to get 0.5gr/watt under these. Here's a link for a guy who did a lot of things wrong and still got that much:

Hey Mike,

How much do the round LED light fixtures cost? How many are needed for modest sized grow (closet grow)? Some of the lights looked rather large compared to the LEDs I've seen in stores (a diameter of an inch or two compared with what looked like at least a 3" or 4" diameter in your pics).

Thanks,

-the Corsican.

We have three sizes: 90w, 180w, 350w and 700w.

Prices: $350, $700, $1300, $2700.

Here's a pic of the 180 turned off. The diameter is 14" and the depth is 4".

For vegetation, you can go with as much as a 4' x 4' footprint on the 180. 3' x 3' is comfortable. For flowering, the sweet spot is 2' x 2', which is 4 sq ft. 180 watts divided by 4 sq ft = 45w per sq ft. You want 40w - 50w per sq ft. So, that's just about right.

Also, you are better off with more small lights than a single large one. The more points of light, the better the overall effect. Your plants will receive more light from more angles that way. I guess that's obvious. But, maybe not.

This is not the cheap way to get started growing. But, if you want to get rid of the heat, the hassle, and the expense of HID lighting, it's a great choice.

Thanks for answering my questions brother. It's pretty interesting to say the least and it looks like it might be the next step in indoor. Pretty expensive though (startup cash) even though you save money in the long run. Why are they so expensive Mike? In other words, what exactly makes them so expensive...manufacturing?

We only use quality diodes that are in high demand. So, the prices are high. Also, there's R & D and a healthy profit margin. Like any new technology, it's expensive, at first. In a few years, I'm sure they will cost a good deal less, relatively speaking. But, who knows what the future holds?

so should I get 3 of the 180's for my say 6x6 area? I have 4 foot aereponic system.. so if u look @ it.. Its a7 foot maybe? by 4 feet...what would you suggest?

I'm not sure what you are saying... how big is the canopy you want to cover?

Here's a link to this large grow's journal, by the way: Cash Cropping with the 180W Jumbo UFO - Grasscity.com Forums

I will post pics... I have a 7x4 maybe 6x4 grow area.. So I would need a few of the 180's then.. Maybe I should get 2 600 watt lights. I cant run 3 like stated.. Unless I run 3 lights right in the row..?

I'd say it depends on your ceiling height. If you have 8 feet, a single 1K could cover that area, no problem. If your ceiling height us under 8 feet, I'd recomend a 600 on a mover, or 2 600s alternating cycle.

Either of those setups should be able to yield 1,000 grams in a 4X6. For cooling I'd suggest 500CFM out 300+ in. Shouldnt need any AC, and you want that airflow anyway unless you run tanked co2.

600s are nice. For sure.

Whatever's right for you and your setup is right.
