The far red thread

[MrTwist1]

You're going to want to find a smaller driver with a lower, wider range for your 5V cob UNLESS you run a few of them in series. You'd need like 6~7 of your 5V cobs to work with that floodlight driver but the current from the driver, if it's constant, may be an issue for your cobs in that it doesn't support enough juice. You may be better of finding a different driver.

Thanks for the reply. I'm finding it a little difficult to find what I'm looking for tbh... my understanding is that the driver needs to be 4v-5v output and 10w at no more than 1050mA, but can be slightly less amperage (will just run the cob softer)... Is this correct? I just can't seem to find anything that fits these specs! I can find 9-12V 900mA 10w driver but I'm not sure if this is any better. I'm still just a tiny bit confused as to how these 3 specs relate to each other and the practical implications.

Yes. Sun has blue in it as it sets too. dark blue in fact. like the night sky. just a couple to create the total effect.
peace

your testing your theory I would guess , let us know how it pans out
not Knocking you I was curious to know why u chose the blues

its already been shown that blue light during dark cycle will prevent a short day/long night photoperiod plant from flowering properly.

IIRC it's Far Red only turns off the plant into sleep mode
that google every article & paste it here to educate has been done over & over
so he's got his idea & i'd like to see if it works for him
I'm just finishing up my Far Red 2 bars this morning
I'll post sum pix tonite

This statement is very true many grows ago I had a timer go out on some supplemental UVB reptile T-8's. The plants kept growing and growing, never flowering, I could not get them to flower or figure out why. Blue in the dark cycle will veg out your plants more and they will not flower...

If you had read the entire thread...someone was getting the emerson effect confused with the phytochrome effect of far reds@ lights out. Yea far reds during lights on=increase stretch. Far reds @ lights out= phytochrome switch from day to night almost instantly. Waste of electricity? My bar is 24watts and runs for 5 minutes a day, thats like pennies a year.

 

[Yodaweed]

Yea its so shwaggy under these cxb3590s stick with those cfls

I don't use cfls I use HID lights and some LEDs, and my LEDs have 730nm diodes and a 380nm UV-B bulb. Good try tho, maybe one day you can grow good bud.

Your led lights have uvb bulbs? Maybe one day you will know what your talking about.

Yes I know what I am talking about, my LED has a UV-B bulb dongle 18% UV-B light (4 COB's as well). Maybe one day you will not run your mouth about stuff you have clue about. Good try tho.

Following on from my earlier question (and following extensive searching) I just cannot find a driver that matches the specs... there is always at least one factor that doesn't match up. So which of the 3 specs is the one which can be compromised? In my mind it is the current (amperage), but I seek confirmation. Which of these selections that I have found to be close to the desired specs would be the best option?

This is really frying my brain right now lol.

Bro, watch GrowMau5's video on youtube. The $20 flower Initiator. He uses Meanwell LDD700's. You ought to use the LDD 1000's though. They can run 3-4 per driver.

Thanks a lot bro. For some reason I had not considered using a DC/DC driver!

Check our recent video on youtube, we use these to drive CXB3590, towards end of video, bear in mind these are only PWM dimmable not 0-10v or resistive

Luckily with far reds, no dimming necessary where they're on only 5-10 mins.

 

[AquariusPanta]

I'd like to read where only 5~15min is needed of 730nm far red versus 30~60min at lights out. In other words, there's a popular belief that 5 minutes of 730nm is all our plants needs but which scientific/scholarley article claims such a notion? From my results, ~15 minutes after lights out seems to do the trick during flowering but I wonder if any have ventured into trying 13.5/12 or even 14/12 with 730nm far red turned on for ~1 hour after lights out and if there would be any ill effects.

5 minute flash at lights out works, plenty of botanical research for short day plants shows this.
I mean shoot, this has been well understood for decades.

 

[AquariusPanta]

Right, 5~15 minutes has shown to be effective but I'm just merely curious on what would happen if we left our 730nm lights on for even longer, not that it's necessary or anything.
