Advanced Lighting Spectrums for T5 Floro and LED

ii had a thought, man if we(me,PF and Fonze) where to start a greenhouse or grow room together that would be some dexters lab shit.

im willing to bet a bud that all 3 of us have tried to record all aspects of our grows at one point in time?(like time daily ph lighting ect.)

I'm trying a small change to my lights and taking out a flora sun and replacing it with a red sun. LST has them growing horizontally and the nodes are very close and they are getting bushy. I want to see if this will increase the node distance and stretch them a little, plus it fills in the red spectrum some.
New lamp setup now for veg and for bloom I'll replace a coral wave and aqua sun for 2 more red suns.

Take out coral waves. Too much 420nm slows growth. I used them for almost a year. I was all about them for the IR. dont use 420nm in flower. I replaced all my 420 bulbs with 450nm - 460nm bulbs. I would use the flora suns over the redsuns.

OK,updated the veg lamp list. Took out a coral wave and put back the flora sun. Thats the best I can do with what I have,remaining lamps are 1 coral wave and 2 red suns.

Im rocking 4 flora suns, 2 redsuns, 2 fiji purple in flower. Soon will replace redsuns with uvl 660. In veg I have 2 ati aquablue special and 4 6500k. Im going to swap in 2 true lume 660 for 6500k and 1 flora sun for a 6500k.

You guys, I'm getting some ultra crazy, super excellent growth happening in veg with 2 x 460nm truelumen and 2 x 660nm UVL. Super tight nodes(comfortably close), nice lush green fat leaves and all my strains are doing well under that combination. I highly recommend. Even my Orange Bubblegum cross is loving it. Sativa and Indicas doing well. I think that any strain can adapt over time to any spectrum. Just give things time to adjust.

For flower, I just set up a new light spectrum that consists of a 400w HPS horitlux and 2 x h350 deep purple. They have that 420nm wavelength in there so I'm gonna see if it sucks ass or if things still roll along. The 400w HPS may overpower the blue spectrum in the deep purples just enough so it won't matter a whole lot. Photos to come. Will be flowering out 1 Serious Bubblegum, 6 Orange Lavender, 2 Big Bud, 2 Orange Bubblegum. Fingers crossed.

He-he, don't forget hyroot. I believe we would all need our own quarter of the greenhouse, and one quarter as a base-line

From my science lab college courses (over 40 years ago), I learned to keep a daily log of everything I did. It's the only way I could keep up with all the DIY R & D I do. A spread sheet would be awesome, but a simple notepad works well. I keep it in the grow room

Yep, but we know IR immediately AFTER lights out makes the plant think it is still in grow mode. So, I am wondering whether putting the CWs as side light would accomplish this. However, if I had 2 @ 4 bulb fixtures, I could put the CWs in between on a separate fixture/ timer for ~ 30 minutes = ~ 2 more grow hours. Not sure there is any benefit in flower though

I've been debating on whether to try the reptile IR bulbs. All I can find are the incadesent ones. I foumd plenty of t5 uv-b bulbs but no IR ones......

Thought the purpose of IR(ACTUALLY IT'S FAR RED 730-740NM NOT IR) at the start of the night cycle was to put the plants to sleep faster, not make grow longer. The problem with the Coral Waves is that they have the 420nm in them which WILL make the plants be in grow mode instead of sleep mode. 420nm is a heavy photoA producer. So if you have 420nm in with your 730nm, it's not going to work the same.

730-740nm is going to have the biggest impact as far as Pf > Pfr conversion. Just supplement a couple Far Red LEDs on a small inexpensive driver. The whole setup would cost under $100. But is it really worth the hassle?

What are you trying to achieve with IR?

same way i felt i considered a ceramic heater but once again is worth the hassle of timing wattage ect. i mean it could be but only if it where cheaper i think cost vs. benefit, this is where cost wins.

well alot of theory relating to a shorter night cycle thought the use of IR ive seen good results using far red bulbs just for wake up and sleep times i would be interested to see the experiments but its a pricey one with a lot of unsure benefits.

IR drives flowering and makes buds desner

Quite possibly I am misinterpreting this.. so someone please chime in

It's only the 'crazy ones' (like us) who'd 'need to' (read: 'like playing around with cool stuff') - let's say - have a bunch of IR LEDs on a separate channel, throw 'em on after lights out to 'encourage' the Pr-->Pfr equilibrium during dark reversion back over to the left side of that equation, and shorten the dark cycle duration required for certain short-day plants as a result:

That's part of it. 730nm works that way and also is used for gene expression as Hyroot said. It is a magical wavelength for sure. Such as growing bigger, denser buds.

I think that some brands of Neutral and Warm White LEDs have enough 730nm in them to do the trick.

but just to point out form previous charts providing the correct amt. will be difficult since it has such a narrow band of absorption at that nm.

we need a bulbs that is either A) powerful and far enough away or B) lots of low power lights that are placed close enough. i would go for the A) route personally.

Has anybody tried out the Ultra Growth Waves ? They look almost identical to the Flora Suns.

No they dont. Coral waves have 420nm and 760nm. Ultra growth has, 420nm, 450nm, 550nm, 630nm, 650nm. The utra growth still has not been released. Even though they said it would be out last Feb.

I said they look like flora suns not coral waves.
Found them here.
