Battery Powered 730nm Initiators and Micro Cabs

[RedCarpetMatches]

Sorry i made a boo boo...i meant to say....: Can i run a mix of 660 and 730 15 mins after main lights off?

i plan to run the 660/730 combo all the way through with the main lights: so total lights on for 660/730 combo will be 12 hours 30 mins...and total for 'main lights'....standard 12 hours.

No. Just far red...no deep. 730 is the magic number found in research.

I am only asking is because I have two small cabs that I flower. I thought about trying an experiment in my Small Cab. I also have a shite load of rechargeable AA's and new ones are cheap too. Enough to be mobile and modular [imho].
Small cab: 3.5 cu ft and 1.5sq. ft.

• 2-3 3w Hyper Red Epistar's from Steve's
• mounted on aluminum [always circulating air inside]
• Although I will have to work out a timer cut-off and I haven't been so ingenious as of yet......

So with money savings and small spaces, I thought this might work. Opinions? Is 6-7watts of Hyper red [730] in 1.5 square feet adequate?

Don't waste your time on using batteries.

Keep in mind that phytochrome is a pigment with two interconvertible forms so the reason behind hitting them with 730nm wavelengths exclusively at lights out is to hasten this conversion from Pr-Pfr. By doing so you can push the lights on photoperiod to a 13 on 11 off. The other thing, which is not discussed much, is that the 660nm diodes at lights on hasten the return from Pfr-Pr.

Doesn't it go from Pfr back to Pr with far red at lights out? Good point about 'sunrise'

I talked to a very credible source today...shocked I got through to "them", and they claim to bloom on 15/9!!! Has to be an Indie dom but, omfg those would be some serious yield. I'd do a run a year! I also think it'd be cool to try some real Jamaican on 12/10 and finish a lot faster...YA MON!!!

I tried to flower a critical cbd with 9 hours dark (and the 730nm sunset blast) and it didn't go. I was about to adjust to 10 dark but I managed to kill the plant so I'm starting over with my testing

I would veg in at least 20+ and then drop right down to 15/9. If not then 13/11. I've accidentally bloomed a Dinafem Critical dropping from 20 to 18...no auto either.

What happens if you just do 12/12?

Should smaller buds be expected?

The problem with all these "exotic" light schedules is that some strains don't play nice with it...............12/12 just works

most hybrids will flower under 14/10.......few won't, more light hours doesn't always mean more bud development, 12/12 from seed has shown to work very well on hybrids

my schedule is slow descending from 24/0 to 12/12 over a few weeks(room temps permitting)........my room ATM is freezing so I went 24/0 for 20 days and flipped

be safe grower

 

[RedCarpetMatches]

I can vouch for 12/12 working and yielding! Mine are coming along very nicely! Must be my awesome bulb Psu doesn't have.

Awesome lighting club: Red and HY...no Psu

Don't waste your time on using batteries.

Why though? efficiency, ease of use, power capacity? For my space, it still isn't out of the question. Even though I haven't done shit to progress the thread, lol, glad other's have put it to use though!

 

[Abiqua]

I asked but they are not interested in selling the battery/boards separately. Down the road they may build a separate Pfr switch but the current boards are built for the diodes they're using with current limiting resistors for this specific application.

Bummer, I was just searching for this answer.

I went from vegging 20/4 to flowering 14/10, down 30 min every few days to 12/12. lots of stretching. Next round, Im currently running veg at 24/0. Then they will go straight to 12/12. I think with the 730nm after lights out and the added hours during flower induces more stretch. Just a hypothesis for now. if your strains are at least 40% indica then do 12/12. If they are mostly sativa. Then 14/10 or 13/11 would be good. Next round is also different / new strains. The new ones all 9 weekers. Where my current strains are 65-70 days. I think they may finish sooner since they started flowering day 8 this time.

Now it all depends on your setup, but I don't agree with this advice.

24/7 often results in lots of stretching and strained plants

20/4 is good for reverting flowering plants to veg, but will often result in stretching for normal vegetative growth.

18/6 is ideal for a wide selection of strains and setups.

12/12 for flowering.

Anything else is simply more risky, and has little evidence supporting efficacy.

well what's this thread about then... (rhetorical). Using 730nm only after lights out... Hmmmm.. I have the inda gro 420's with led pfr pontoons. So....... You got your veg cycles backwards. 18/6 will induce more stretch while 20/4 and 24/0 will have far less stretch. The more hours that the lights are on , the closer the nodes. Try it and you will learn that from experience. Where sativas originate from, they flower cycles are longer days year round. Where indicas originate its 12/12. Even in the U.S. When plants start flowering outdoors in late summer. The light cycle is 14/10............

Forgot to mention I talked to Bill at growlightsource.com today and he said he was looking into a lower cost screw in flood design that would only be water resistant for more of a indoor application.
I'll post updates on any info I get from him in my "Flowering with Cree bulbs" thread

Posted this in another thread if anyone is interested.

Captain, I have a link in here somewhere's....for 730nm bulbs from China somewhere, not cheap but cheaper than the 20w fixture @ $50.

The lumigrow bulbs are just as expensive @ $150. http://www.greners.com/i/grow-lights/led-brand/lumigrow/lumigrow-ecc-fr.html

Advanced has a 15w bulb @ $87 [cringe]

This light can only be used during lights on because it has both 660nm and 730nm so it would not work as a flower initiator. In phytochrome 660 nm triggers the the plant into the daytime state of P fr and 730 nm triggers the plant into the nightime flowering state of P r so used together the 660 nm would cancel out the 730 nm.
