How close can you get to a vero 10 or whatever cree chip you would propose? In these boxes space is the limiting factor, so a bunch of small high efficiency cree or vero leds would be pretty bomb.
What light is recommended for flowering in my small grow box?

So you're telling me the 300w Galaxyhydro I just bought is only pumping out about 150w? That seems like MAYBE just enough to flower 3 decent sized plants at once. Maybe I should start looking at low-wattage supplementary HPS before I switch to 12/12 since I'm looking at 4+ plants here...

and bulbs
That is the best bang for the buck, but will require you to install a plug and connect a few wires via push in inserts. About the easiest DIY electrical work you can come by.
That would add 96w of T5 lighting putting you into the perfect amount of light and great distribution, and no lost space as the plants can hug the bulbs if they want.

My 300 watt blurple panel pulled 175 watts at the wall, seems most are in the range, I have watched my friend flower a few under his mars 300 ( basically the same panel),, yea they work, the grams per watt isnt as high as the cobs, 4 + plants ,, probably not, unless they are in 1 gallon pots and close together and SOG method,, the 300 can do 2 plants in a small scrog in basically a 2 x 3 at most

Consider it a well educated guess since they don't seem to publish the actual driver specs. If you want to know for sure, plug it into a kill-a-watt and you will know the actual consumption. You can fairly assume they drive the LEDs at 40-50% of the rating as these chips just produce heat and burn themselves out if you go much past 60% their "rating".

I definitely like the heat reduction in LEDs, not to mention the higher lumen/wattage ratio and the greater aptitude for full-spectrum. But while THC production goes up as heat levels go down, you simply don't get as much of some of the other beneficial chemical components of marijuana, such as CBD. Haven't researched the science of it, but it makes sense that lights created through different means will have different properties, including various heats and frequencies, all the way down to how the particular photons are received for photosynthesis, and how readily, efficiently, etc. From what I have heard and researched, LED panels seem like the way to go for a variety of reasons, but I wouldn't be opposed to the use of a different type of light to augment, maybe pack in a few of those other chemicals LEDs don't seem to produce...
At any rate, Mr.Hush, your Galaxyhydro UFO appears to have all the red/warm color spectrum you will need for flowering, but perhaps a few more watts wouldn't hurt. And be sure to implement plenty of cool/blue spectrum light during veg. Whether it be MH, fluorescent, or LED, getting that high frequency spectrum boost is like steroids for early veg growth!

1-2 ounces would cover what I need. And I am in this for the long-haul...where i live you have to get it from someone else for around 500 an ounce. Im sick of paying for something I can do myself.

I am now on the side of COBs, white lights, here is my latest cob build, I prefer the white light of the cob builds, they have much more higher par levels and PPFD levels

ok. great answer too by the way!
here's my idea: keep your grow box and led for vegging. buy a tent for flowering. like a 3x3x6 would be good. buy a 315 watt LEC for flowering.
you can use your box to either start seeds in or clones. get them about a foot tall and then move them inot the flower tent. as they get towards the middle of flower, start more seeds/clones and keep that going.
figure on about 3 months minimum from start to finish. so 4 harvests a year give or take. that should get you right where you need to be.

Tim Fox, I am unfamiliar with this type of lighting, but I will do some research momentarily. I was reading somewhere that an overage of white light is not as beneficial as reds and blues, or other colors in general, but perhaps that statement was just in regard to white LEDs?

Are LECs really that efficient for flowering? The only ones I've seen have been around 6500K -MH color. Also, I understand that it's still new technology, but they need to be cheaper before I can even make a serious consideration concerning them. Damned monetary limitations!

funny how most of us stoner growers are cheap,, I cringe at spending 40 bucks on my grow shit,, lol

they are very efficient. they come in 3100k for flowering. they also have a veg lamp too (4200k i think). run much cooler than hps/mh.
i had a problem wiht my hps and had to go back to 400 watt CMH that iv'e had for years. they really are a much better overall spectrum than hps or mh. very similar to a white led.

i used to be like that. now that i haven't bought weed in 3 years, i don't give a crap what things cost anymore. one good harvest and just about anything is paid off IN FULL.

Lol, for real though xD
Ok, so COB is just a chip-on-board type LED which provides higher thermal resistance as well as more power efficiency. Gotta love the information age
My question is- what is the cost of such a setup, how many watts do I need? Are they hard to build? Maybe I could use something like that as an augmentory flowering light to my HYG05 mini?
