:smoking: ayuh! Nothing more than a cautionary comment to folks my friend, and my carelessness.... I knew it was fierce at the COB face- .... roger that on the expalination,.. Sm0, I forget the spec's on these particular COB, wattage drawn, CRI (90 I think)? I'm dangling them at mate, grow shops,... I see a similar idea type unit at one, couldn't see the name, but it had a fan and a circular metal perfrated cage surrounding it,.. I'll get a pic and name, just for shits and giggles,... your comment on efficiency made me think of unit,... time to go shame it with yours!

>> @Mizzo81 -- ... I hear ya,.. I'm not sure of the light is directly responsible for such growth aberrations, but for sure intensity can affect the compactness/node stretching length of them! All my plants in the new tent, photo's included, were growing squat and wide,.. the F1 auto/photo cross (that oddly auto'ed) shot up fast as soon as it went into Sunlight, and the laterals seemed to stall out-

I do appreciate the comments. Maybe I should attach something to each order as a caution. As far as the similar light there are plenty popping up all over the place. But I do feel like companies overlook quite a few aspects of what makes a grow light do so well. That’s the cob. Efficiency, lumens, par, spectrum,wattage ext...only go so far. After trying dozens of cobs in countless grows for years I finally landed on this particular cob for no other reason than it’s perfornance. What it does to the plants is amazing. The thick resin, the size and growth of the plants and buds, the late harvast colors that seem to come on very strong and vibrant. So if a non grower we’re to build a light they may be more focused on the first part and not the last. As a grower the results matter more than the sales.

As far as fans go that’s something I’ll never add to my lights. First off they are noisy and most auto growers are growing for personal use in their own homes. Heck I can’t could the # of tents I have seen wedged next to their beds in their bedrooms. Secondly even quality fans can fail. Their power supplies can fail too and if you have a high powered cob on a thin heatsink being cooled by a failed fan things can get real nasty real fast. It also adds size with the additional parts that take away from the beauty of the AutoCob.

Do we end up with any custom issues/cost

I can help with this a little on my end.

Hey Biggie, quick question regarding heat in small places. I have purchased four of your lights and will be running them exclusively on my next grow, although I may not need four. My space is 2x2.5x5 and I have been running a Timber Growlight, 4 COB Citizen 1212 CLU048 and I have gotten good results but I want to try the Auto Cob to compare. First of all, will four Auto Cob be an overkill and second how much do you think they will increase ambient temp in the grow space. With the TGL setup I am seeing about an 11 degrees F increase but would love to cut that down so, if less lights will still give me adequate light then that in itself should reduce the heat. BTW, I am growing four plants in three gallon pots. Thanks Dude.

I think u can definitely pull one out in that space. Not sure how much that’ll help the temp.

In all honesty, one Autocob per plant is more than enough, especially in the small confines of a 2x2 (you might consider a scrog grow). I am currently testing two plants with 2 Autocobs and those plants aren't doing anything out of the ordinary. Two other plants have one light each and one of those, the Mamba Negra, is a big big lady. She asked me if her jeans look tight and I turned and boogied in the opposite direction.

I am reminded of the time I was in the US on business and at a bar that I was a minority. Two large 250lb plus gals tried to pick me up for a 3some. Me being a skinny white guy. One of them would have been too much, but two? Man, I boogied my ass out of there real quick. thankfully I'm still alive.

I’d run 2 cobs max. Don’t forget the other light may work well for photos but with autos it’s waaay to much. There are a few guys I follow who went from hefty cob setups down to less with AutoCobs and their results were definitely better. 1/2 the wattage should also be 1/2 the heat.

@BigSm0 Hey Big, I will be buying lights soon and was thinking about some of your 6500. What is the differences between that and the3500 when it comes to PAR and yield? I have been liking the grows from your customers.

Thank you. Everyone is killing it. The 6500’s are more for supplementing the 3500’s. The 3500k is king when it comes to veg and flower with what I feel the perfect spectrum. The 6500k is very blue and more for veg and can be helpful in late flower for boosting resin.

For a 3x3 I’d run 4-3500’s
For a 4x4 I’d run 4-3500’s and 1-2 6500’s
For a 5x5 I’d run 6-3500’s and 2-6500’s.

They can be used to increase coverage area too. Which is what I usually do and recommend.

As far as par goes the higher the temp the higher the efficiency. They use phosphor to coat the cobs which changes the spectrum. Since the cob is blue to start with they have to add less to the higher temps, (6500). I will say with certainty that you wouldn’t notice any growth increase based on the efficiency part.

I was thinking of getting one or two 6500k myself and was wondering how you differentiate between the different spectrums. Is it just by the color of the light or do you mark them somehow?
