Detroit J420 · Apr 1, 2011

Mann i been usen leds since the first ad in high times sellen the first ufo from hid hud priced at 6 hundo your kicken out what 400 hps could do a 600 would have fatter buds. And plus with that long ass veg you ran its not addig up. Leds are only good for veg the best for veg. plus your gonna lose potency you need that fire from a hid to kick out buds and potency i would love to see an led flower grow with uvb added that i wanna smoke but hey keep expirementing

i hate to sound uneduacated but there isnt any real exact specs on the wavelengths that come on those lights.. The website says 11 wavelengths but what are they? I just recieved 2 of those lights and put 4, 3ft tall GC's under one and 10 little 1ft's under the other. I want to do a little experiment before things get serious.. So my question is the diodes (there are about 6) that dont light up.. are those the far red humans cant see? and they are for real?
I usually grow under 400's and avg 4 plants per light so i know exactly what i usually get under identical circumstances and i always use the same strain. i will look into doing my own journal but i'm not familiar with that process. so do you mind if i leave a little of my own feedback with you? I know the GC is a 6 week strain and not a heavy producer but if i hit a 1/2 pound on 2 lights i will be sold..

My understanding is that the 6 "unlit" LED's are uv and ir. uv for mould control and ir to prevent stretch.

If you don't get a 1/2 pound on 2 lights I would be surprised. My first crop I got almost 12 oz off 2 lights and had nute issues so things were far from optimal.

My current crop is doing really well

i hope thats not the case cause i'm gonna try it for myself.. i started today and i'm gonna try to do a journal..but if its shit i'll let people know its shit.. but i'm hoping i didnt just light my $1500 on fire

dalamar999 · Apr 1, 2011

thanks Dunit..i'm hoping...i truly hope it works.. i'd love to get rid of my 400's.. i dont get quite a 1/2 right now per 400.. so if i can hit that easy with 360watts, i'll be switching right over.. i'm gonna try to put a journal together but i am very new at the internet growing.. peace buddy..thx for your responces

Hmmmm......interesting opinions.

First off, the long ass veg was entirely temp related. If you veg under a 400mh try keeping the room at 70F and see how slow they grow. As soon as I got the heat kickin they took off. It was kinds cool cause on my current round that I'm about to trigger they were way ahead of schedule so I dropped the temp in the room and voila......slowed them down and now they are on schedule.

As for fatter buds, I have always pruned my plants to concentrate the growth on the outside buds and not waste it on popcorn. I let my last round run without pruning and although I got the weight, I had lots of smaller buds. I've had the same thing happen with HPS before. Having nute lockout in the later weeks didn't help either as that's prime time for the buds to fatten.

As for potency, best bud I have ever smoked is LED.

Feel free to hang around and see how these ladies are taking off :-)

Lol Colorado! Ya he seriously doesn't know DICK! Just look at Dunit's previous grow journal. He fucked up with nute lockout and it was still bomb ass dank!

Dunit, your babies are really budding up real nice! Much props!

I really don't think you'll be dissapointed and please post a journal, the more the merrier.

If I can point something really important things about the Magnums (and LED's in general) to help you to dial in your grow quicker and maximize your results. Magnums have 60 degree lenses. Many LED panels have 90 degree lenses and I've even seen up to 135 degree lenses. I think that a lot of LED grows run their panels too high (to get bigger coverage area) so they lack intensity and the plants stretch (looking for stronger light) and waste energy stretching instead of producing. The important thing to understand is 60 degree lenses have half the coverage area but twice the intensity when hung at the same height as a panel with 90 degree lenses.

I think that hanging the lights at 12-15" is optimal if you are running taller plants and 24-26" if you are scrogging of running lots of short plants that don't need the penetration.

No matter what, LED's just aren't made to light trees as there is a limit to the useful distance of 3W diodes no matter what the lens angle and I think anything beyond 3 1/2 feet from the light isn't usable intensity. If they are being used to grow trees I would side light with additional panels.

You might hear some people say that 60 degree lenses don't allow the spectrums to mix properly but if you do the math on the lens angle and spacing of the LED's in the panel you can quickly figure out that overlap (proper spectrum mixing) occurs at about 5" from the panel so no issues there.

Good luck

Excellent insight into the actual use of LEDs as always dunit

If i was you i wouldnt run it at 1600ppm ever. Pk maxes out at 1400 even if your co2 is 1800ppm. I wouldnt run 1400 with-out the co2
Its more like 1000-1400ppm. 1200ppm is ideal . How do you cycle your watering scedule? I told you i went by days for ppm. I go by days and make a recipe off that. Week for week. But depends on how fast they need water to decide strenght of ppm.
Do you flood your garden?
Some people let alot of run-off. They pretty much go "out with the old and in with the new". But they let there pots dry up a bit more. Day 1 feed and then day 4 flush Then day 7or8 feed. But if your pots dry up faster, You have to cut the dose down. Say if you had to water every second day, you would have to cut your doses in half. Compared to twice a week or every 4 days.
Some people grow beds and have no run-off. So they pretty much just top/off when dry

I was planning to start feeding my plants every other water, which would be Day 1 feed, then Day 4 water. And I was going to start at 25% the strength. But the guys at my local hydro store told me the nutrients I am using (House and Garden) is designed for full strength feeding and feeding every water! i asked them about nute burns, but they told me the manufacturer from Amsterdam, designed everything for Buds. We shall see next week when I give my plant her first dose of feeding!

Sounds about right. I've got these ladies at 1600 but my tap water is 220. I'm running 3 gallon pots so watering every 2-3 days.

Yea thats good. Anything can give you burns. Less is more. I would start. Wk1 half strength/veg nutes wk 2= 3/4 strength. Then wk 3-6 would be full strength. Then week 7 i give them 3/4 strength then week 8 is flush.
My friend told me about this stuff called Hydro Fuel a+b. He also uses superthrive and pro-bloom blend. He told me since kush is a hardwood strain he cant handle that much. He said 1000ppm from week 3-6. A+B nutes are stronger than GH flora. When i pump co2, i run my ppm 1200 max then flush. If you have big plants then you can run it a little higher. But depending on pot size 1400 max. AKA Soilbeds.
I do it in 2 gallons with three week veg and do 25-30 a light.
Im gonna run GH at 1100ppm from week 3-6. The additives i use are B52 and voodoo and koolbloom dry. I was using connoissuer for a bit but it got to expensive.
Ive heard bout the HnG and when all my Gh is used up im probly gonna get my friends strain and grow it how he says with the Hydrofuel and problend/b52 and voodoo.
He isnt growing Kush. He doesnt know what it is but he says they just call it "kills"
