So, I made this light...

Hello All,
I've been gone for a while, but back in the game again. Real quick about me: I grow dirt or hydro scrog, and talk in actual watts.

I built my box, and had it all figured out except for the lighting. I'm an old CFL guy, but in starting again I want to go LED and build my own COB setup, but haven't gotten around to researching; shopping around for what I want; building it yet.
Long story short, I had access to super cheap throw away vanity lighting, and LED bulbs for $1 each.

I also wanted to do a test grow on my box with bag seed to make sure the box could handle temp and humidity extremes in either direction.

So, I made this to do the job until I have the time to build the lights that will ultimately replace this thing. I'm in the middle of renovating a house and had most of this stuff around anyway. Keep in mind I grow scrog, I threw it together in about 15min one night in the garage. If I remember right it measures 3'x3'. (I lifted it in the first pic so you can see it.)

I threw in 100W of 3000k CFL's for added spectrum, but the rest are 5000K. I honestly don't know how many bulbs are on there right now. I loosened them all, and just tighten a little when I want, so some aren't lit yet. I'm also going to put more Y's along the outside when the time comes.

As of those pictures, here is the wattage: (Not all bulbs are screwed in yet. These are 9w 800lm 5000k, and for flower I have 17.5w 1700lm 2700k bulbs)

It's not really doing that bad of a job. Not very much stretch, they seem happy.

As far as heat, it isn't that bad for what it is. My setup right now is set for 80-82F and 50-55%RH, 18hrs. It really doesn't try that hard to keep it in there. I've never seen it go out of range, actually. As expected, the light plays tricks on my camera. In pictures and on video the numbers to my meters scroll, but that says 81.3F.
20180610_225802.jpg

Now that it's built and been running, I kind of want to see what it will do. It's a beast.
If enough people are interested, I'll do a journal on this light if only for education purposes. My box has passed all tests, but I'll do a full run with this bagseed under this light. I'm really curious to see what it will do will a load of 2700k 17w bulbs. Might just call it good and push my real cob build down the road until winter.

Oh, the plant in the center is 3 weeks old and topped yesterday. I had 4, had to kill 3, so I'll keep topping this one until the others catch up after a top or two.
Don't judge my setup completely yet as it isn't finished, just finished enough for now. I need to get my scrog setup in there and reflect some of that side light back.

That seems like a real expensive way to run having all those separate bulbs but I def could be mistaken.

Go to Horticultural Lighting and get quantum boards.....75% more efficient than bulbs !!

Those bupbs work better with the diffusers on. I did a good grow bigger than that with about 15 bulbs. I tested both with and without diffusers..

Things are working out and thats a cool thing to do, but i feel like its using way more power than it needs to, to do the same thing. Im vegging more than that very happily under about 80 watts with the diffusers on.

I applaud the attempt , but looks like a fire hazard . First the 2x4 subframe must really add to weight.

My 2¢ ......

Find another option for lighting .... Cobs , quantums or Samsung strips .
For the actual pull of the 700 watts you managed can be done with less bulbs / vanity panels. You seem to have the DIY SKILLS so you could fab up a light that will power in any config you want plus possible dim functions for all stages of growth. A simple 4-6 COB frame or rail build would open your eyes. QBs are the DIY friendly way to combine led / cob performance with lower heat ( based on power load ) and better spread.

I built a few configurations using QB and haven't looked back. They are easy to " design " a setup ...... Panels are approximately the size of a white sheet of paper. I laid out 2/4 sheets on a table to MOCK UP a new build , using aluminum angle to make the support rails and get size of fixture desired. You can use 4 QB panels , run a 600w meanwell driver ( type B ) for dimming and decimate what your home built could ever do. Plus the fact you can disassemble the panels anytime and make the four panels into a dual set of QB each running separate power configurations.

This is the early mock up of a quantum build that would incorporate both QB and COBS.
Cool thing about these lights is that you can just swap out the driver to a more powerful one to increase the power it can max out too ..... Which I later did and saved this old driver choice for another build .... It is ridiculously easy .

You are definitely ready to build and grow but sometimes cheap gets expensive.

Good luck and keep us posted.

You didn't read the post, if you did you skipped how I threw this up until I have researched; found; bought; and have time to build cobs. I figure about a month, so I'll just go ahead and run this lot through.
Oh, and they're 1x's. The hangers will hold 150lbs. each, the box is a brick shithouse. https://www.rollitup.org/t/big-perms-grow-box.967126/

what does that even mean bro?

And BigPerm, man, ur spending an assload of Power, for a little bit of bud.

My COB setup is using 200-250 watts, and crushing it. $250 bucks around, you got a light. I think even 1-2 cobs, will be 200% better then what you have using 700Pluswatts

He will do but for now he'll use this bulb based light. For sure better like an CFL based light and even with it's 100-120lm/w bulbs he'll get a decent yield! He even mentioned it two times, is it really so hard to understand..?

I threw in 100W of 3000k CFL's for added spectrum, but the rest are 5000K. I honestly don't know how many bulbs are on there right now. I loosened them all, and just tighten a little when I want, so some aren't lit yet. I'm also going to put more Y's along the outside when the time comes.

As of those pictures, here is the wattage: (Not all bulbs are screwed in yet. These are 9w 800lm 5000k, and for flower I have 17.5w 1700lm 2700k bulbs)

As far as heat, it isn't that bad for what it is. My setup right now is set for 80-82F and 50-55%RH, 18hrs. It really doesn't try that hard to keep it in there. I've never seen it go out of range, actually. As expected, the light plays tricks on my camera. In pictures and on video the numbers to my meters scroll, but that says 81.3F.

I'm really curious to see what it will do will a load of 2700k 17w bulbs. Might just call it good and push my real cob build down the road until winter.

Oh, the plant in the center is 3 weeks old and topped yesterday. I had 4, had to kill 3, so I'll keep topping this one until the others catch up after a top or two.
Don't judge my setup completely yet as it isn't finished, just finished enough for now. I need to get my scrog setup in there and reflect some of that side light back.
How much does that sheet weigh? I would of bought some knock off Qboards, like 30-40$ each

Crafty as fux though.

yeah, i understand that, and yes, I did read that. But most of them arn't even directed towards the plant. Im just saying, alot of wasted Power, more money. just seems like a fire hazard and a huge waste of money.
