Flower tent LED build

[Powertech]

They emit any light at all?

let you know in about an hour

 

[Airwalker16]

let you know in about an hour

Yes please do!

 

[Powertech]

Yes please do!

Longer than an hour, got to doing other things, but yes there seems to be light, not real sure how bright. I wasn’t willing to look at it, just took a pic with my phone. Just jimmy rigged something up for the night. Will start taking progress pics, but probably won’t update much unless I see something worth updating

 

[Powertech]

I’ll set them up on their own timer in the morning. I’m going to put them about 18” away, ish, and run them for 15 mins every 3 hrs. I have no idea what I’m doing, but gotta start somewhere

 

[Powertech]

Fuckers get hot as shit though, gonna put a fan across the heat sinks.

Guys I wish I could be of more help with respect to data on using these, the issue is we have sold a few and really are waiting on grower feed back on results and the best way to utilise them, my info I am providing, such as it is, is based on what research is out there, and there is not a lot given these are bleeding edge so really looking for user feedback. The data supports increased THC via the UVR8 Protein. The issue is the balance between too much UVB and possible plant damage vs the increased potency and since these leds are relatively new, the advice is judicious/proportional use but we going to need a few runs to test the theory. Im in a non legal country so cant grow and test claims. Cheers

Australia is not legal? guess i'm not going there lol.

Anyway, I have them temporarily installed. They are at about 18" I guess, and am going to run them 3 times in the 12 hr period. I guess now that I have 2 flower tents I really should do a comparison, but I don't have much incentive to interrupt the grow plan I have going. I'll put my meter on it in the morning and let you know exactly voltage and mA I am running, but it should be around 80 volts @ .625 mA

I would have the board well heated and fan running to keep as cool as practical

As soon as I turned the fan on it, was just like all the other lights I got from you, heatsink went from barely being able to touch it to "Is this thing on?" Probably doesn't hurt that I kinda oversized all the heatsinks lol!

@welight hows supply looking on your far red strips? I need 2 more of them, i think they have helped a lot, my flowers seem to be maturing much faster than normal. Likely want some other supplemental lighting for the newer tent as well. Looks like the white strips for the new tent have to wait as I will be testing some boards for somebody. Will be interesting to see how they compare to the lights I have in the other tent. Won't have them for about 5 weeks though, but would like ALL of my supplement lights finished before hand.

You run far red full 12 hrs?

Is that the 280mm version?

 

[Powertech]

yeah, full 12 hrs, all other lights 11.5. Pistills were showing up by day 4-5 after switch, and it has been 5 weeks now and they look like week 7

yes, 12 diodes each, but I will be getting all the supplemental lighting together, save on shipping. Open to suggestions on supplementals. I am for sure doing the 2 far reds i have in the other tent.

That's very interesting. I've only ever ran them at lights out. I wouldn't feel they'd even be worth running during lights on because they're powered so lightly. It'd get washed out by the main light and be pointless.

Not sure how you can wash out a light wave. The wavelength is still there, being absorbed. I do not run them during lights out. Far red in nature still comes from the sun. It is normally absorbed by the plants lower leaves and tells the plant it is in the shade, giving it the signal to grow. Leaves will get larger, but you will also get longer spacing between nodes, totally fine and sometimes beneficial when using ScrOG techniques. Leaving the far red on during daylight is partly what I contribute my fairly even canopy to, because I have not screened them yet. My thought is it tells the lower growth to grow. I mean, this is pretty even for 3 plants in a 5x5...that damn DrGrinspoon maybe not so much, but she is a weird growing strain anyway, guaranteed popcorn

 

[Airwalker16]

I mean for 15 minutes after lights are off -.-

 

[Airwalker16]

I guess I could try running them alongside the main lighting, but there's only 12 of the diodes across an entire 4x8 and the whole of them in series is 35 watts, so like 17.5 per 4x4 lol. Just doesn't seem like enough up against the 500 of white and red on each side.

Couldn’t hurt? Well I guess it can hurt the wallet and the life span of the diodes....

I guess supplementing is about what you wish to try emulate or do with a grow. A drawn out veg whilst scrogging, or fast turn around from clone to finish would call for different lights. Even outdoors daylight is not constant with warmer colours at dawn and dusk (and Autumn/fall).

search @jarvild posts if you want a working ratio of whites to supplement reds, suited for grows with the usual tent/ceiling heights.
