If it's all free then I'd say without a doubt go with 4 of the 180w panels!

re: GLH 600W LED Grow

i wanted to get a discussion going on on here. wanted to here everyones opinions on this? ok, so when i was first talking to mike about doing a grow with his light i never really wanted to just get one 600w unit i really wanted two 300w units or a few 180w units. but at the time he didnt have them in stock only the 600w unit and he also wanted me to do a grow with a big unit because their isnt really too many out their. so i said ill do it. but later on i would want to trade out the 600w for some smaller units so i can spread out the light more and get more foot print.

Now my question to you guys is do you think its better to go with three 180w units or two 300w units?

do u think to more intense light from the 300w units will grow fatter bud or the larger foot print from the 180w unit that i could keep closer to the plants because of the larger foot print will grow fatter buds?

i would love to here your opinions on this?

i think id rather have 2 300w over a scrog, sounds killer to me! ...you could find there is little difference between 2 x 300w and 3 x 180w , my guess is the more powrfull led's would be better.

i think 2 600w would be stellar which is what i will use on my next grow.

well i am not trying to hustle mike i would only take equal price and wattage that i already have. 600w $1,900. and if i decided to use more lights i would pay for them out of my packet. i have no problem sending some money his way, he seems to be a honest guy to me; and seems to have a good led light. i would only ask for equal value to what i already have, then i will ship my 600w back.

thanks! i am leaning towards to two 300w's, i was all gun hoe for the 180w in the past but i think the more instens light would help. they when its freezing in my grow room in the winter ill just throw in a 250w or 400w hps in the middle with no ducting to keep things warm when its freezing.

i think 2 600w would be stellar which is what i will use on my next grow.

no shit bro! that would be bad ass. but i am not looking to run that many watts at this point and time. if i was going to use that many watts i would just probably run two 600w hps and do a big ass grow area. but either way i am not looking to go that big at this point and time.

i would love to see you do a grow with two 600w led lights and maybe you will change my mind? its is nice not running my vent hoses across the room, now everything is nice and backed away in the corner on the room.

3 units is better than 2...in the right spot. you may have a problem posistioning 3 evenly..if you cant then go with the 2....more light sources...more overlap...thats basic theory

that is true. right now my 600w light is 34"x13" but its i went with three 180w's i would have a 39"x19" cover area with all the 180's side by side. now is i space then say about 4" apart then i would have even more foot print. see my thought is ya the 300w is more intense light from on unit but with multiple units of 180w i will have a larger foot print so their for i can keep the lights closer to the plants and make up for the intense light the 300w would have. sound right?

if this grow on mine right here finishes good id be willing to run 1000w of leds for my next grow. so i could go four 180's or two 300's with a 180w in the middle. remember these lights use more power then their names. each of these setups is about 1000w or so.

see i know if i would have went with some smaller units from the get go i could knock this grow out of the park. could have each plants under its own light for a pure led mix and intense light on them, most of the plants right now are just getting showing light not direct light under the 600w unit. i could only imange how fat they would be with a light over each plant. i think my next grow once i pick the better strain witch looks to be the hindu, and more foot print with at least 6 girls ill pull some mad weight and buds. i can see the potential these lights have, once things are dialed in.

I was having the same dilemma when deciding which lights to order. Either two 300's or three 180's. The chassis between the 180W and 300W are essentially the same (19" x 13"). My grow space is 3' x 4' x 8'. So i figured that I would go with two 300's and if i feel that i need more penetration or coverage I could add another two 300's (total of four). If I started with the three 180's i might conclude that it is not enough light and I would hate to have to replace the lights. It seemed safer to go with the 300's.

re: GLH 600W LED Grow

Irish, what I would like to see you do is. Run that exact same light in that exact same area with 6 HS girls lst'd just like you did here, BUT put the 600w unit on that light mover you got! I think this should be your next progressive step forward don't you.. You already got the mover right?

Remember a (single point light source) is a lot of the secret to making big flowers.. i.e. The sun or a 1,000w HID bulb.

You can easily end up with a garden full of small flowers if the led's units are spread to thin..JMO

2 300w w/ a 180w in the middle sounds like a winner.

re: GLH 600W LED Grow

Well I read that for cfl's, at least, have more lumen output per watt on a 23 watt bulb than a larger bulb like a 100 watt. If its similar at all I say go for more lower watt lights than less higher watt lights. In the end it's up to you Irish.
peace and good karma.

thats one thing that i am afraid of, too thin of a light spread. i would love to use my light mover but, its too heavy for the light rail. trust me ive tried. once i harvest, and i can have the light out of the room for a while ill go to the drawling board and see what i can rig up to make it run better.

re: GLH 600W LED Grow

i think the logic behind more smaller lights with LED might be a bit flawed IMHO. Your comparisons with the footprint are made with the notion of regular grow bulbs with ballasts.

LED lights are not one bulb with an entire spectrum ... they have to mix different colors together at different intervals to get the desired spectrum result.

Mike has already said his 180w light isn't big enough for his single plant anymore. In your own logic ... at a bare minimum to get the optimum footprint for each plant you would need a 300w over each one ...

if youre going to do that ... youre still better off using 2 600w lights due to the patterns of LED spectrum ... unless he changes the overall shape of the housing of the lights.

Optimum shaping would be some sort of contact lenses type shape or an X. I don't know the optimum pattern of LED's to get the desired spectrum..which may or may not dictate the overall shape of the light/lenses.

have you ever been on an operating table and looked up at the lights before you go under? they are like an X shaped H that are concaved so they can focus/direct the light over a small/broad area depending on circumstance.

Personally ... i would rather him double the amount of diodes on the board and decrease spacing between them. Essentially making a 300w size 600w with a directed lenses either for dispersion or directed light. If that wasn't an option .. i would like to see the shape changed to represent something more like contact lenses or concaved X.

very good input. i never knew he said his 180w was too small for his plant, thanks for making that clean to me. ive never been on a operating table but i do know what ur talking about. and i would love to see a led light that is concaved, ive been thinking about that for some time. great info brother thanks!

re: GLH 600W LED Grow

This is a good problem to have irish!

I grew under 3 126w HGL lights and although they are inferior to Mike's lights I always felt like I needed more wattage and intensity per panel. On the other hand I would not want to put all my eggs in one basket. For those reasons I would go with two 300 w bulbs. You can always add a couple of 180s later as side lighting and then you would really have some fat nugs.

What is Mike's opinion on this?

very good point, i like the 300w idea because its more universal, i could have two 300's and a 180w in the middle that would get the intense light from both 300's also, then when its freezing cold in the winter i could throw a hps im the middle to keep things warm.

IDK mikes opinion on this, waiting for him to post his thoughts still.

re: GLH 600W LED Grow

i think 2 300's and 180's on the outside where the footprint begins to fall off. 2 600w lights would more than cover my tent with a 4x4 tub ... 1 almost does it... actually when my plants get up to the screen there will be no issue at all.

Im actually astonished at the undergrowth ... not even my ouside plants over the years have grown so much underneat ..but then again ..was growing brickseed too .. either way i cant complain ... 80 degrees with the light on and the tent shut up ... 74 at night time ... cant really beat that.

I just wonder how much more heat would be generated with another 600w.

if you don't have to send it back irish ..id buy yours off you. would work well for everyone involved.

i was thinking that, a mix of the two also and might go that way. depending on how this grow turns out i might run four 300's instead. ill make my final mind up once i see these plants on the scale dried.

ya the veg growth is off the hook with these leds and u cant complain about the low temps. so far i am happy with my results from the looks of things as of now, and i know their are a few things i can do different and boost my yield, i just have to focuses on getting things dialed in with this light first. next time i will do more plants with smaller hight. right now my xj-13 are around 4' tall. ill keep them around 2.5' next time. and stick with one stain only instead of having different ones, just learn one stain at a time and see what they like. i also want more foot print so i can keep the lights closer. in veg i had it around 25" and in flower its been 18-20" from the tops witch is impressive by the bud size i have at that distance with leds.

re: GLH 600W LED Grow

wow, 18-20" and they're budding like that?

that's not much different than HID distances.

very cool.
