So I was watching the Mr. Grow It pod cast and this guy Dan from The Green Sunshine Company stated that after the lights turn off on a grow and you use IR light it will put your plants asleep faster. Now I dont know how long exactly you are supposed to use the IR light for but I would imagine not very long. Has anyone heard or practiced this. If so what are the benefits? Faster flower time maybe?
someone was talking about this for tarp less
depos, but they never really explained it

What’s tarp less depos?

they will pull a tarp to darken a greenhouse (cover) so they can flower
in the summer
the big players do it with automation the small guys do it by hand
if you did not have to pull tarps it makes it easier

If you haven’t watched anything from this man, I would suggest a listen while you garden lots of interesting stuff about the different spectrums of light

So I use this:
You run it for 15 minutes at the end of your light cycle. Its supposed to stop metabolic processes that would normally take 2 hours to turn off. Basically making your plant react as if it had an extra 2 hours of darkness. I’ve heard of people using these and flowering in 14/10 cycles, but I haven’t tried it yet myself.

Wow. Thanks alot guys. This is really interesting. I’m going to have to get a puck. I tried looking it up but I was searching IR puck and couldn’t find anything. I guess I was looking up the wrong stuff. I’ll definitely be back with some results. After my next grow.

I’ve been considering picking up this same puck. Has it made a noticable impact?

Give a plant that needs a short day one hour of darkness
at the middle of their day
and it will flower as if it is a long night short day
works the other way also give them one hour light in the middle of their
night and they think it is a long day
they stay out of flower

What? I’ve got my lights on 18/6 BUT broken into 2 segments (cost savings) So light is on 7am to 7pm. Then back on 11am to 4pm. Are you saying the plants will think its time to flower under this condition? I hope not lol

back in the day I worked for a commercial grower
doing flowers for florist trade
we had a glass greenhouse ( back than they all were all glass)
it was about a quarter of the size of our others
inside we had a curtain system to black out the house
and lights to light it
so we would darken house for about an hour at noon or light lights
at midnight
when you are in the flower business you need flowers
a side note when I first started in the industry I worked for a grower
who did poinsettias by the train load
we were outside of town and started having a problem with people breaking in and stuff
so they put up security lights on the end of 4 of the houses
that fall the plants at the light end of the house did not flower for Christmas
than someone was Duh? the lights running all night

But knowing how cannabis likes to hermie if there’s a light leak… wouldn’t that increase the likelihood?

if that is to me in a greenhouse it does not matter
they do not have light leaks
but how ez is it to stress a cannabis plant with light?
I have had one hermie in 20 years and it was genetics
keep breeding with and to all that feminized stuff and see how the
hermie thing plays out over time
my vision of the industrial THC weed grower for the pack of
joints market that will come in time
they will be doing 2 - 3 crops a year all feminized and all autos
planted just like any other commercial row crop
of course hopeful we still will have the boutique type bud
grown by that type of grower
and with any luck that will not look at us all like illegal distrillers
that is why I have been trying to grab some of the old stuff
and make beans with regulars to put away for a rain day

Hey @dequilo are you saying adding an hour of lights out in the middle of your day while flower should give you the same result as you would with the initator puck?

nope just telling you what was done with darkening and lighting
plants in greenhouse when I started working in the flower trade for
a commercial grower
I believe all the puck does is burn up the enzyme that keeps
the plant from flowering
what I was talking about is a low tech version of the same
principal
that is why I have always give my plants 36 hour of darkness
at the start of the flower cycle
in the dark the red enzyme is depleted and they sets flowers
go to 12/12 it happens over a longer period of time
the puck from what I have read does that thru IR light
so what would take 12 hours to deplete has a kick start of
2 hours

EDIT
if you do one hour of dark at mid day short day plants will flower
if you do one hour of light at mid night your long day plants will flowers
clear as mud eh?

The puck is no good for our use huh? The video @anon93244739 posted saying far red only promotes flowering in long day plants (Plants that flowering during long days).

a good read
it is great if you can use it to deplete the enzyme that keeps the plant out of flower
they say you can flower a plant using it under 14/10
which if it is how it work would be good for some growers
all the best
