Gas Lantern Routine

In Bloom
Posting about this here because I Use it and havent seen anyone mentioning it yet.

The basics behind it are that cannabis needs 12 solid hours of dark to produce enough of the maturation hormone to initiate flowering.

The basic light schedule is
12 hours on
5.5 off
1 hour in
5.5 off

This keeps the plant right in the edge of flowering but still in veg. Reduces the energy use DRASTICALLY and keeps plants growing short and bushy, for sativa this is an awesome technique to reduce height and for indicas it just further encourages lateral growth

And for me the largest bonus is the fact that when you do switch to flower the stretch is reduced easily by half, because the plant is constantly on the edge of initiating flowering , when you do remove that hour of light in the middle it switches much much faster than from say an 18/6 schedule. Keeping nodes extremely tight and again reducing the necessary overhead room.

When switching to flower I give the plant a 24 hour period of darkness to allow it time to generate as much of the flowering hormone as possible signaling a full balls to the wall transition, further speeding up the switch.

During flowering I use what's called the diminishing light routine

You start with 12/12 then depending on strain and how long your flowering period lasts you go down to
11 on 13 off
then 10 on 14 off

This encourages trichome growth, using 12 hours of light during the initial growth of the buds giving them as much light as possible to form large dense buds then slowly reducing the light which tells the plant winter is coming and it resins up its buds as much as possible trying to catch pollen before winter.

These are just a couple things I personally practice that works for me, I only grow for a personal amount for my wife and have attempted to set up the most automated and best potency method possible.

I use core with coco sensitive grow and bloom along with big bud during flowering.




I personally combine this light schedule with topping and screen of green technique in a 5x5 with a single hindu kush at the moment. I simply fill the net to about 80% capacity then initiate flowering


During veg I use an led panel, to further cut costs, and then in flower I switch to 1000w hps




I've attatched a puc of my plant still in veg under the gas lantern routine with screen of green. Shes a beauty!! So dense and such tight nose formation!! Notice how full the screen is and how many bud sites are at the same height with full light exposure, this is sure to be a full and potent harvest!

There is a guy who talks about this light cycle in veg but he runs an 8 on 16 off for flowering. I have not tried it yet but will get to that experiment eventually Joe Pietri is who I seen sayin somthin somewhere. Very cool:stoned:
I read an article in skunk magazine that talked about something similar. It referenced the poinsetta industry practices. Facinating stuff, it may even have been written by him.
 
Bump...
Idk if the OP is still around. But I have thoughts. Mostly questions tho.

Was gonna start a thread but I'll just post in here... bring back a 5 year old thread.

Id love some input.

I'm trying to think what I can do to minimize the electric bill and the heat for summer. I'd like to keep some mom's til fall when I start up again... by some I mean probably 16-20 haha

Standard GLR 12 on, 5.5 off, 1 on, 5.5 off.

Is this the least amt of hours of light I can use to keep em in veg long term? 4 months or so... Slower the growth the better.

Why 12 and 1 for light? Why not 10, and 3? Or 11 and 2? Or 9 and 4... or:

What about 1 on 7 off, 1 on 7 off, 1 on 7 off?
Or 1 on 11 off, 1 on 11 off? This may seem dumb right, would the plant just think the days are micro days and flower anyways?

Isn't the idea that the flowering hormone needs a certain amt of dark hours in a row to trigger flower?!

Or is it a certain amount of light per day to not flower...

Or both

Anyone mess around with these sort of alt lighting?

I know nothing and am having trouble thinking what will go wrong here, other than they flower and herm like crazy haha. And I'd lose all the mothers...

Apologies if this is all nonsense, but it would be great to get any input people might have!

If this is nonsense I can just use the typical GLR. Or 18hrs veg under low light leds plus some HST/extreme pruning.
 

Hinges on accumulated darkness.

Would imply 12 hours of Darkness in a row are not conducive to vegging


Or 1 on 11 off
Plants get taller in the dark. At some point they're just going to stretch all to hell.

I have never tried this 'moon-blinking' stuff, so I don't claim to have any experience.

Just my two cents on your situation specifically:
If I was challenged to keep a plant alive through the heat of summer, I would take clones.
Cool basement floor, stunted in solo cups, 24/7 light.
T5, T8. Perhaps LED bars would suffice, if you're into that sort of thing. Wouldn't need much more than a hundred Watts
3 or 4 bulbs/bars to create a 4x4.
3 clones of your desired 16-20, you could fit 60 in there
Re-clone or Top as required.

Again, while not addressing the thread topic, I can only intelligently reply from familiar ground.

i've used glr. IMO I think it's better to keep a plant almost ready to flower (so when they bring them to market, they flower and look pretty).

for a mother (which i've never kept), I'd think something like 6/2 which i've used for veg cycle) would be better . just keep them barely in a veg state.
 
What about 1 on 7 off, 1 on 7 off, 1 on 7 off?
I think you could get away with something like this.
I have a fleeting memory from when I was first doing non-24 hour day stuff that 8 hours continuious darkness was the cut off for initiating flower on a short day plant. I don't recall the context of that info but I did flower under 10/10 and kept the veg times pretty close to the same 18/6 ratio but also remember vegging under something pretty close to 12/8 if not exactly.

Some ooutdoors cultivators use the moon for when harvest. Have seen growers to turn on their headlights to help with harvest
