Irish Boys GLH 600w led grow

i want to thank irish for his unbiased results and attempts to clear the confusion and bring some light to the led controversy. kudos to you. i do have a question for you since you have so much led experience now. i am considering either using a single 1000 watt hid light or approximately 1000 watts of leds. watt for watt do you think the leds could produce the same yield as hid? my concern isnt the expense of led lights over halide. i have serious concerns using a 1000 watt halide and the long term expenses associated with cooling and ventilation. i am also concerned with noise. a 1000 watt bulb needs some serious ventilation as well. your thoughts are greatly appreciated

um i would say yes i think watt for watt led could match or come close to HID. but its the whole cost thing that really gets you. but if money ant a thing they i would say you could come close to HID. but let me say that you would still need venting with leds a 1000w of leds will still put out allot of heat. ur best beat would to buy smaller led units like 180w or so and cover ur plants. that way you would get more covarge area and be able to keep the lights closer. put if you picked the right led company i think you could match HID watt for watt. i am very curies on if this 600w led can match 600w of HPS. from what i have seen allot of newbie growers are getting high HID yields with leds, but i tend not to believe everything i see on the forums. i think HID will still produce higher quality denser buds. look at some leds grows and some HID grows and you can see how much tighter/more dense the HPS buds are.

i would still think HID would be better because you dont have to adjust all of those lights and it would be wayy cheaper to get a very nice setup. either way ur going to need a vent fan because their will still be allot of heat either way. but i would say yes you could match watt for watt with the right led company and if you used the led right. keeping them close during flowering.

keep an eye on Rumples grow or mine and we shall se for sure.

irishboy I'm happy I found your grow, I'm planning a SCRoG with LED's and I need some info, I'll be watching your grow for sure.

I'll be lurking around here Irish.

Nice thread, I will be looking forward to see how the LEDs do

irish u should or someone should try this set up i use 2 400watt hps with 4 90 w led ufo over 2 4x4 tabels ebb and flo and it works well really well i wont post pics as im not as legal as some haha

ya i have heard leds make good sub lighting with HPS

no brother not good fantastic there insane the amount of sugar dif compare to hid alone

here are some pics at 7 days old. i started to LST them yesterday.

Hi Irishboy, really digging the LED grow. I just constructed a cabinet with a 90W UFO 9:1 ratio. I figured you, having had a good bit of prior experience, might have some advice on whether this would be enough for a single plant I intend on LST'ing. I was think about adding in 2, 26w cfl (100w equiv.) but I have a few concerns. One is heat. Also I would have to place them under the sides of the UFO and possibly block a few of the individual lights in the UFO. I'm also worried the heat from the CFL's may scorch the UFO plastic cover. I'm not sure how heat resistant that clear plastic is. Plus with those lights I would have to keep the plant shorter to avoid burning so the effectiveness of the UFO would be reduced since the further away the plant gets the less effective a LED is. Any input on this would be greatly appreciated, and good luck on your grow.

you should be good with a 90w ufo and one plant. but if you could somehow add some CFL without causes any troubles then that would be allot better. but if it was going to cause a problem then i would say just use the 90w and youll be fine. just keep the 90w close during flowering and use mylar to reflect the light more if you already haven't.

I think I figured out how I can add the CFL's. They will be pointing straight down but should fit in just fine. I am growing them in rubbermaid tubs, ghetto I know, but I've had great results with it. They are lined with a doubled up layer of white duct tape.

I am using a 180w jumbo UFO with 2 CFL's and it is working great, I managed to hang them in the middle lower part of the plants that usually does not get light to bump up the lower buds and it is working really good

So figure out some way to hang those bad boys

Good luck

Pulling up a chair for this one. Even though I don't have personal experience with LED's, I am a believer & am stoked to see what will become of these 4 ladies. I'm thinkin monsters with that light!!

sub'ed.

oh my grow is 2 days ahead of yours. it will be cool to try to keep up. right now yours looks great!
