Yeah, no doubt man. I've always kept veg times to a month after 12/12 from seed on my first grow to harvest yielded virtually nothing but anger.
I've grown with virtually nothing but cfls prior to my cobs.
Made me a pro? Of course not. Helped out a lot with yield, bud density, ease of use, and plant health? Of course.

Currently only pushing about 350 whp at all 4 wheels. So probably 450ish at the crank. Thanks man! You too! Good luck with ya grow!

Thanks you! This quicksand kush is turning out amazingly sticky. So mamy trichomes and big thick pistils. Looking through jewlers loupe the bud almost looks wet from all the thc crystals.

the reality is that COBs are only about 50% more efficient than the bridgelux diodes used in these cheap grow lights and these multi-band lights produce a more useful spectrum. the new ones using 5 watt diodes seem to last a little longer as well. the trick seems to be finding strains that will grow well with LEDs. many high end LED grow light makers claim that plants can only use 40% of the light produced by white diodes and cree or osram mono's are just as efficient as white COBs. there is still a lot of disagreement as to the best spectrum for LED grow lights and a lot of strong opinions. seems a lot of young new growers are attracted to these cheap LED grow lights and some people are getting acceptable results with them.just not the energy savings LEDs claim a cheap 450 watt (200wat actual power draw) will not replace a 150 watt HPS. (horticultural enhanced spectrum). I'm not convinced however that spending $1000 for a high end LED to replace a 600 watt $120 HID would be cost effective. but then I'm not in love with my lights and continue to test lights looking for something better.

it is strain dependent but some strains do eat their lower leaves near the end of flowering.as long as it does not spread to the top of your plant you may be OK. you should only be 12 days from harvestAs a matter of fact here's what I just pulled from my tent

I'm a fairly new grower, running led.. I'm impressed for the price I paid. Does what it said it would do.. next grow I'm gonna throw another in to really pack on density.. as it sits now my complete system, light, fan, extraction fan, and water resovoire pump all draw less than 250w... Well,well below the limit of the outlet. I also run perfect temps and humidity with the need for humidifiers or dehumidifiers.. the light spectrum argument is logical in my opinion, I'm no expert, but technically speaking; we usually improve on previous generations. Aka hid,my,ect... U see it now with the cobs

This late in flower I would say no. If it was in early flower (first 3 weeks) then yes. I had one that crept halfway up...starting taking our some good leaves that were receiving plenty of light, so I added 1/2 then 1/3 dose of ff grow big to my next 2 feeds (along with mu regular schedule nutes) it stopped it in its tracks. This late in the game though your def ok.Thanks loads...was hoping it was that

Ya it's common in plants that stretch a lot as they're starving for that extra nitrogen. But that's usually in the early flower stage from what I've read.

50% more efficient sounds good to me! I use cobs because I had the money to buy them, they are compact, can be used for 10+ years (unlike buying new hps/mh bulbs every few grows), I don't have to change lighting from veg to flower (3500k), and I simply like the way they look. Got tired of fluffy buds from cfls and having to constantly keep them close to my plant's.
My buddy thinks he is going to blow up a bedroom in his house by hanging 4 vipar 450s in a 12'x14" bedroom! I tried explaining to him that he's going to be hugely disappointed with to whatever yield he's able to get. Told him he might as well invest in 1000w hps' instead, but he doesn't want to hear me on the matter so fuck it! Lol he'll have his "assumed" 1800 watts of growing power and be on his way!

Yeah that's not gonna happen... The footprint for each light is only a few feet and par drop significantly. LEDs are good usually for a single big plant or a few small ones... But I'm sure u know this

That's what I'm saying man. He's oblivious to the fact that it's a pipe dream.
I felt bad a few months back because he had 8 clones in 5 gallon pots under ONE 450. I stood back and shook my head. Ended up giving him a 100w Chinese 3000k cob to help him out a little.
He's still growing the same 8 plants, which are now stretched to about 3 1/2 feet tall, under the vipar and cob. Asks why his buds are squishy and not dense, why he's got small colas. I feel like a parrot repeating myself about light intensity to him.

He's lucky he didn't drown them... whatever some people just don't wanna learn...have u suggested he visits this wonderfully informative site?

He was very much drowing them in the beginning! He had the 5 gallon pots soaking with fresh clones in them the first time i checked his plants out, which were two weeks since planting at the time. Im sure they had very little to no root activity because of it. They vegged for a month and barely grew a few new leaves. He was also feeding the clones full strength nutes EVERY watering instead of using plain ph water at all. I have NO idea how his plants survived before instructing him to let them dry out then flush the shit out of them and.only watered when needed. He's a dude under the impression that more nutes and water are going to make it grow faster, well..up until I saved his crop. I've linked him up with this site, growweedeasy.com and ilovegrowingmarijuana.com on numerous occasions. Cares less to visit and learn so oh well, lol. It's messed up, but I can't wait until he pulls a few ounces off 8 plants so I can say I told you so.

Can't wait to see a harvest update! Curious to see what you get for final weight. I'm looking to get a 600w viparspectra for my 2x4x5 tent when I start my indoor plants this fall. I'm thinking of just growing one plant in the tent

So far, from my experience with the viparspectra units, is for the price , they are one of the better quality , cheap Chinese led units. I've seen some impressive grows using only these brand led. From the what i have gathered all the top canopy nugs are gorgeous and full and sticky. But still does not quite have the penetration power to go beyond that first couple layers. I've been researching and experimenting on my own and have found that using a smaller watt HID. 250w or 400w hps as your center light. Then using multiple small watt leds to light up the edges of the grow can allow you to get the best of both worlds. Better penetration. Spectrum. Heat shouldnt be difficult. I currently and doing a run wirh 400w hps. 450watt viparspectra and about 6 - 23 watt 2700k cfls . Getting some pretty darn good results. Just food for thought!

Viparspectra 600W (280W actual) is around $200, for the same price you can pick up a couple of COBs from TastyLED (140W max actual) that will put out more usable light than Viparspectra 900W (400W actual).
When I found this out I came to question why anyone would buy the Viparspectra panels.
If they were half the cost I could see them being a choice.
As long as they keep their prices inflated COBs will stay superior.

Are they legit cobs? I go onto the cob site and every led listed is soooooo much more expensive than all the other sights I see selling " cobb lights". Like 30% of what cobb was listing there prices at. Telling me thete is a catch somewhere

$179 right now... I honestly have never heard of COBs til today when I started browsing threads lol
