Just did this in celsius and just about had a heart attack. Looks like I need to increase my humidity a bit on that one. Thanks for the insight on the charts @Aqua Man

That would be a nice setup. Im way too cheap for anything like that though.

Thanks and hopefully something there can help you out. A nice clean build would be ideal I'm just way too cheap, sometimes it bites me but it worked out this time.

Im running the strips fairly hard and with a cheap walmart 6" fan blowing on the corner of the fixture everything including the driver stays cool to the touch. The temp readings I took were without a fan blowing on the light. Those brackets are amazing cheap heatsinks.

I feel your pain. Being in Canada sucks when looking at everyone state side building their cheap awesome projects. I just happened to have a box of braces left over and thought they looked about right. Here's a link to the build. If your strips are more narrow then they should work just...

They are the exact width of the eb gen 2 strips. Think they were just shy of 1" wide. I did the build over on the afn forum. Not sure if I can post a link to it here.

If it's for strip light I used the metal brackets used to hang drop ceiling with amazing results. They are the exact width ..and come in 1ft 2ft ..and 4ft sections.

I Have been looking for a basic straight forward VPD chart to cover the 3 main phases of plant growth. I found the below attached chart. Wondering what everyone who has experience with VPD charts thinks about it? As long as it is within say a few percentage points of a fully detailed chart...

Well if everything is good except your environment then you now know what your problem is. Environment is probably the most important variable when growing.

Could be bigger but it looks good and healthy so it doesn't really matter. How long are your lights on for, and what's your humidity at? Perfect environment and extended light cycle helps with vegetative growth in the early stages for autos. Also if you are in plain coco that's going to cause...

Yeah that was my original thought process but as soon as one fuse popped/strip failed, then the subsequent current would be sent to the next fuse/strip. So by the time I got to check on things I'd have 11 popped fuses and some hurting plants. I was looking at resistors to wire in series with...

Yeah I'm still happy with my choice but you know the whole newer bigger better thing. Though I do have room on my driver for up to 4 more strips so there is always the option of mixing the 2 provided their voltage is the same.

I just finished a gen 2 build why didn't I see this thread before I pulled the trigger, dammit.

Do you plan on running these with your other lights during the full lights on period?

Thanks for the info whytewidow. How far have you pushed these strips? I'm running them at around 1.15 amps each and without a fan on them my temps were below 40°C, got a 6" fan angled at the corner of the fixture now and the tc points are all below 30°C. A resistor to prevent the strips from...

Thanks for the reply. That's pretty much the reason I asked because I've never seen it myself either but see the recommendation for fail safes in multiple discussions. I got looking into it a bit and couldn't quite find what I was looking for. Inline dc fuses in the 1.4 amp range seem to be...

Just built a strip light with 12x 560mm strips, wired in parallel. Wondering if anyone wires a safety device (resistor/fuse) in series with each strip to prevent thermal runaway? If so what are you using?

This is really great!

I got bored so it's experiment time. One plant got a feed with the non ph'd solution of 4.6. One plant got a feed of the same solution ph'd to 6.8, find out in a couple days which one is better or whether or not there is any difference at all.

For those who use these nutrients do you adjust the PH or not? My well water has a PH of 7.8 and a ppm of around 120. After mixing calmag+ and Bio Bloom at the suggested rate the PH goes down to 4.6. I've got compost and worm castings in my peat and coco soil mix but didn't add in the lime...
