What are you looking to build? I just finished up with all my lights for now. 2 flower lights, and 1 Veg light with the influx strips.

Do you use a humidifier, if so what kind? I'm shopping for one now.

Wow.. looks amazing @Takeshy !!! I've built my 2 new flower lights based on your strip light you built!! Did you dim these lights on this grow?? I know you mentioned on the last grow that you had some burn, and you wanted to dim them down.

@calitrees916 , Have you taken any measurements on the light at the canopy such as lux/lumens? I'm curious what kind of numbers you're getting. The samsung strip lights( 20-influx L09 / 3000k per light, and they are 48" x 42" each ) I'm getting anywhere from 75-80 lux at 6-8" below the light...

I've been growing under SE HPS bulbs for last 10 years or so, and I've been waiting to pull the trigger on LED's. Everyone I know that's growing locally uses and swears by DE HPS lights. I'm looking forward to seeing for myself what these lights are able to produce. Savings on energy cost and...

@calitrees916 , I've been watching your grow from the beginning and I almost pulled the trigger on the HLG boards. Instead I went with the Samsung strips with lower amps to each strip and have the light close to the plants. What's your thoughts on these LED's coming from HPS? How are the buds...

Yes I'm going to flower with it.

My first DIY LED light, and it's my first LED grow light. 20 - 22" Samsun g in-Flux L09 strips on alum tube driven with 2ea HLG-480H-48B. Control box with Daylite AC meter box, potentiometer, sonoff.

@Airwalker16 That's the plan. I just transferred these girls when I took these photos. Super crop, trellis, clean up the leaves for more air flow and light is still left to do. :weed:

The AC dayite meter at the time I took the photo's. The temps on the strips was at 105F from my temp gun directly on the strips.

I did some testing with the lux meter, and here's what it looks like. About 6" from the strip on the tallest plant Taken at 12" from the light The lowest plant in the group at 15" from the strips

What's the calculations to figure out the efficiency? Is this it? LUX / 1000 * 15 = PPFD LUX / 69 = umol/m2/s What other formulas are there to keep handy? I have a $35 lux meter from Amazon that I bought during this DIY saga! I've seen on RUI people using it to judge the position of...

Sounds about right. I was going to buy the spydrX light, so I'm well below my original budget. I like doing DIY projects. The frame is built out of alum tubing - 1" x 1-1/2" x 1/16" thick. So when you try to screw it together, the tubing is not thick enough to hold the screws. It strips...

@Airwalker16 - Thank you!! Building my first LED light was a learning experience. There's a few things I'm going to change on the next light. I have all the parts here to build the second flower light now. I wanted to work out the "Bugs" first. I would buy 25 strips to save some $$($3.70...

The first light is almost done. Just waiting on the "AC" bayite meter to finish my junction box. Did some testing so far with the temps. I ran the light for a 1/2 hr with 78F ambient room temp and no fan blowing in it. The strips reached 100-102f or 38-39c. The driver(s) temp was the same.

Strips have landed!!!

Thank you!! The bars are actually 1-1/2" wide x 1" tall. In the picture I posted it looks like 1-1/4". If the light I'm building works good for 4' x 4' foot print, I'm ok with that too. Somewhere in between 5' or 4' square will work. It seems to be trial and error and part of the fun!

I'm doing 20 strips total on each light fixture with 2 HLG-320H-48B drivers(10 strips per driver). Two rows of the 22" strips @10ea(double row H-inFlux L09 strips). Mimicking Takeshy's light setup he did. 700watts at the wall, and 670mA per strip. What would be a good space on this setup...
