No, they are ISIS-1's, this is my 2nd grow using them my first grow is here https://www.rollitup.org/general-marijuana-growing/378470-confined-space-850w-led-master.html I changed a few things around this time. Last grow the plants were on average 12" and I pulled down 27.25 zips off of 850w. This time I am growing them to 23" added one more 170w panel and upped the pot size from 2 gal to 3.5 gal. The enviornment is sealed and I am running co2 through the entire grow this time instead of just flower. I'm hoping to pull down 40+ oz this go around.
Here are a few pics of the bud from last grow...

well first off.... they don't suck.... they are both really good to be where they are right now..... I'm a raiders fan..... i know, i know...... if i had to root for a team still in, i'd root for green bay. only because aaron rogers is my fantasy QB.

That pic is of the 500W
Theres a 240W in there as well but not really visible on that pic

What you guys think about that post... you can post here or message me when you have the time thanks again guys this thread has been very informative to me.

Super nice guy too if you have questions he's great about answering them all even though his threads are crazy busy. It was watching his grows that gave me the confidence to buy some of the latest generation of LED's.
Although I must say props to LedBudGuy for producing killer results in such a small area. Really demonstrates to the hobby grower the potential of every attic or crawl space which is great for those needing the stealth element.

Oh im sure they work fine for veg, but I can't see a flowering LED match up to a good metal halide for veg. MH are way to often slept upon and they rock IMHO. I kinda want to cop a veg LED and see if that stacks up. Like I said vegging is far too important to ignore and leave to the flowering spectrum (unless thats all you got). I suspect that a lot of complaints against LED grows can be solved by a true, good long veg, just like any other grow.

Well the plants need red and blue spectrum together just in different proportions depending on what growth cycle your are trying to maximize. Lights that concentrate their output in the blue spectrum are better for vegetative growth. Lights that concentrate their output in the red spectrum are better for fruit/flower production. I would say that if you are running 8-1 red to blue then you are too heavy on the reds for veg and even a bit heavy on red for flowering. Definately some cool white CFL's will help add blue light and balance that out. Daylight CFL's are full spectrum so they have just as much red as blue and you already have tons of red which is why I would go with cool white CFL's. You can get blue CFL's at grow stores too but not sure about the price point so you might be happier with just cool white.
More light is better in almost every situation so when you get your new panel I would run both if you can but still keep the cool CFL's in near the Chineese panel to balance it's spectrum.
If you run heavy reds for veg I find you get leggier plants. They are taller, don't get much sidebranching and don't have very heavy foliage. If you flower under heavy blue you get less flower/fruiting production so less bud weight.
I always found that the fullest spectrum was best. If you veg under hps and mh the plants that are in the middle getting light from both (but in lower concentrations) seem to do the best. Likewise I found that when flowering under both you get the same results. The plants getting MH and HPS light produce the best. I think that's a lot of the appeal behind dual arc but I don't like them because they're still HID and produce lots of yellow/green spectrum light which is a waste and you still have to replace your bulbs all the time.
UV light is good for mold suppression which is why that is often included in grow panels and IR, in low levels, is good for stress to induce flowering which is why that is often included in grow panels.

Not sure if this has been posted before
but one of the better charts I've seen.
Great for not only helping visually represent the light absorbtion of plants (PAR) but I thought it was really cool for helping understand where the color temp, or Kelvin chart was as relating to PAR so people can figure out what temp of additional light to add for balance if their main light is heavy in red or blue.

@dunit nice chart....i think thats the simplest one i've come across thus far

Yeah I really like how they overlayed the human eye over the PAR. Basically shows how the light that is best for plants we can barely see. I think that's probably a hell of a marketing struggle for LED's because basically the best lights for plants will look dim to us. I also think that's how the HID guys keep on believing because when you look at the same plants under HID or LED the HID appear so bright.

Hey thanks alot dunit lol I was about to call you wolfman lol I really appreciate it I know the chinese panel has all its blues in the middle and all reds on the outside. I figure it would do justice in veg it seems to be doing a good job but just in case its not I got 2 daylight cfls pinned at both ends of the panel pointing torwards the leds so they get that cross lighting with each other.

ok guys been lurking for a while now i have a question for you guys who have a blackstar i have ordered a few other items off epay pumps,timers,bulbs etc. and was dissapointed in the "discreet packaging" when the return address has hydro etc. etc. on it i think we can all agree this is not very discreet. so my question is how is this unit shipped?does it say gotham hydro? how else is it packaged any thoughts or info will be appreciated. i am going to be purchacing a few led fixtures soon and am going to try a hid/ led comparison of my own with stinkbuds aero system. also i was wondering about coverage i am wanting to cover a 8x8 area in flowering eventually phased in over the course of a couple crops and was thinking 4-500 watters should cover it but some of the posts on here have got me considering going with a greater number of say the 240 watt model i have always been of the opinion that more light is better and have been running 1-1000mh and 1-1000hps on their own light movers to cover said 8x8 area but electric bills are killin me and i am ready to make the leap into the next generation
sorry for such a long post!
thanx in advance for your input

Actually just red an interesting and fairly technical article on IR for flowering and it's not a stress thing. More that its the balance of red and IR that affects the two types of phytochrome which triggers growth or flowering. The idea being that any parts of the plant in direct light get more red than IR and thus flower the parts that are in shade get more IR than red and keep growing until they are in direct light. Not sure if that makes sense but the techincal version is really long winded.
