    Introducing CobKits.com - specializing in DIY and Citizen COBs

    IDK, I am ok with paying $8-9 more for a CXB3590 3500k DB bin over the 1818. Hell, I paid more than that for my 3070 early adopter tax :) But they are still going strong at 45.5% efficiency :D

    Which suppliers here have components in stock for COB lighting?

    And again, what can you do on pricing? I already looked at your site for pin cushion heatsinks and they are outrageous. I dont mind paying a bit more purchasing stateside but $21/heatsink plus shipping? Hell, Jameco is listing the HLG240 for $8 less than you are and I know you can source...

    Which suppliers here have components in stock for COB lighting?

    Item not currently in stock but placed on back order - select "Edit Order" to modify purchase. The error I get when I add to cart.

    Which suppliers here have components in stock for COB lighting?

    I remember awhile back many of the suppliers here stating they could beat Jerry's pricing. Im looking to build a couple lights. Ive been to many of the sites but no one has components in stock, let alone cheaper pricing? Cutter has a few things, but not everything to source a build. Looking...

    Norabachi ? Anyone Anyone?

    http://timbergrowlights.com/200-watt-citizen-clu048-linear-framework/ If you are looking for something pre-built, that is inline with (what seems to be) your price point. PPF is 20% higher for slightly higher cost. Still a bit low on efficiency but you get what you pay for. Or you can look...

    Norabachi ? Anyone Anyone?

    That light MIGHT be ~35%-38% efficient. That is horrible. At that efficiency, 2 of those wont even equal 1000w HPS. Just stay with your Apollos. 1.7 ppf/w is not very good FYI.

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    HPS is end all? Not hardly... I did the blurple thing like a dumbass then moved on. Running COBS at efficiency levels no better than DE is stupid and pointless. We are WAY past that but whatever. I built a light 2 years ago that was 45%+ efficient with COBS. Here we are 2 years later and...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    I see why so many people are venturing away from RIU. It has turned into the troll city of 420 around here. Sad days. Whats funny is, people eat up this guys bullshit like its gospel. If they actually figured out efficiency levels of some of the shit he pushes vs. TOTAL cost, they would...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    All you are doing is trying to push your bullshit to sell product. The problem with this is its just that, bullshit. Learn from some of the other vendors here. Sadly, many people will listen to you only to realize that they wasted money on a side step from what they currently have. Keep...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    Ok and you are forgetting about materials to put it all together. I guess you could do like the old days and hang it from wire and a screw but who wants to do that? By the time you buy wire/framing/screws, it gets pricier. Oh, and you did not figure in shipping (unless you are selling HLG-185...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    Where are you getting $0.50/watt or less from? You cannot touch cobs for that. 200w of COB lighting for $100? If it was that cheap, no one would EVER consider DE/CMH. From what I am seeing, unless you are a direct supplier, you are looking at about $1.20/w best case DIY (and thats not your...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    Yeah, but when you are pricing up a 1000w DE vs. 800w of slightly more efficient cobs, I will take a DE. So many fixtures being sold at 45-49% (and kits) and IMO, that is a complete waste this day in age. A couple years ago sure, that was acceptable, but not with current tech but people...

    Opinions on how to light a 10x10 flower room Quantum, COB or Both?

    Efficiency? Is that not the whole reason we enjoy them is the higher efficiency levels? Even though most are still buying less than 50% efficient kits..

    Need Information on Cal/Mag Deficiencies When Using Led Lights

    I personally run some of my nutes separate, one being Cal/Mag (even though the deficiency is Mg, the plants have never had an issue with C/Mg so its easy).

    Need Information on Cal/Mag Deficiencies When Using Led Lights

    Been discussed a lot. Search for it. Basically, anyone claiming that COBS do not create the potential for a higher intake of Mg should not be growing. I have experienced first hand the move from HPS to COB using the same strain (clone) in the same environment. I have also tried to keep my...

    DIY kits now available from Timber!

    If you bought the 300w CXB3590 from Timber that was $100 more than the GoGreen CXB3070 fixture, then yes it is a better light (but not by an "absolute mockery"). If you bought the $589 CXB3590 300w from Timber, then they are about on par with each other. Different chips but also run at...

    4'x4' COB grow advice needed -- 3, 5, or 7 gal plants?

    Looks like your "sativa" got more of the NL dominant pheno. Either way, I think 3 more weeks of veg might be a bit much. Plants really take off from where you are at now and shoot up quickly plus your flower stretch on the NL/Haze will be bad if it turns out to be Haze dominant. As far as...

    1000w Citizen CLU048 1212 Garden

    Errr, not sure. Maybe he should clarify. I read that as 3 meters squared (which would make more sense in his context). If its 3 meters squared, then is nearly 100 sq ft actually (was late last night) (96.8 sq ft). Would make sense with his 3600w calculation that way as well.

    1000w Citizen CLU048 1212 Garden

    3 sq meters he said. Thats 81 sq ft (bit more actually).
