Gas Lantern Routine

You can see my experiments with the technique on my you tube channel. It works well for some strains but not others.

I'm running a perpetual flower, and I'd like to give this an honest try. Is there a solution to running a continuous flower while adding new plants to keep rotation going?

Subbed !
Just flipped to 12/12 from 18/6.
Do I wait for 14 days to start reducing by a half hour a week?

You might Gary. I am in the middle of projects. But in the next two weeks I will start a grow report with pictures to show off this lighting technique.

Looking forward !

The real gas lamp you do 11/13 flower. Never 12/12 at all. Then each week increase the dark period by 30 min each week.

I got to that right away and am now on the diminishing light schedule, 1/2 hour less every 2 weeks.
A little over a month to go !

I heard of the GLR about 5 years ago, a couple grows after I moved inside after growing outside for years. I came to understand quickly that darkness was your friend growing cannabis indoors. I currently start on 17-7...drop to 16-8...then 15-9 before flowering.
Flower on 11-13 then 10-14 half way through, sometimes end at 9.5 or 9 hrs. light...

I have 2 problems with 12-1...the first is the firing up of your MH bulb twice in a 24 hr. period. I always heard that it's not just hrs. of use but how many times they are fired up that impacts the life of the bulb... So, is this a problem with bulb life or not, do you think?

Second is...I know this sounds ridiculous...but how the hell do you set up digital timers that have just one off time and one on time for each day? You would HAVE to use those old fashion analog timers?

I'd like to try vegging GLR next time...if I can resolve these issues, if they even ARE issues...?

I'm practically flowering like the GLR now...I just don't do the consistent weekly reduction, but 11-13 to 10-14 half way through is pretty close...

Also, the last few years I worked rotating shifts...and I changed my flowering photo period weekly...by adding a few dark hours to one of my nights...so the lights would come on at the required time...so every week on 11-13, one of my days would be more like 11-17 to get where I needed to be...did this the last 4 years until I retired earlier this year...and none of those added hour, longer dark nights ever caused me a problem... I also have an extended dark period before the onset of flower, instead of 12...more like 18 or whatever it takes to get me to the time I want the flowering photo period to start...

So, what are you guy's opinions about double firing your MH bulb daily during the 12-1...and does anybody use a digital timer?
What brand of digital timer allows multiple on and offs in the same day?

Both VERY good questions !
I was trying to figure out how to time the GLR veg as well.....
I never thought about the extra firing of the lamp.
One solution, if you could add some bright LED strips in your cabinet/flower room, you could put them on another timer to light that hour separately ???
Hhmmm... got me thinkin now...

Most people change their bulbs when they lose intensity over time anyway. The extra firing shouldn't cause it to lose intensity however they wouldn't last as long.
Most times that I change a bulb it's still firing up just fine just not as bright as new.
Some people don't change them til they have too though.
The electrical savings would be worth an extra bulb a year

Bulbs are cheap And most people replace them yearly. The money saved in electricity probably outweighs buying new bulbs.

Use an analog timer. Cheap and they last a forever.

I only tried it once and the plants seemed to stretch a bit in veg so never tried it again, that was years ago and only one strain. Seen some grows that were perfectly fine on here though. An amazing way to save on energy usage. That was the whole reason for this I believe and it was from a commercial poinsettia grower that showed me how it worked.

I am throwing 2 seeds into water today and getting my next grow started utilizing the entire Gas Lantern Routine schedule.

All righty guys, I've been using the GLR for some time now so I could share the experience so far.

@fishdeth once mentioned the GLR on his thread. I switched to this cycle after about 5mins of research (I know I'm lazy), as I was curious of the results. Although a lot of threads put me off, because of the sheer amount of disbelief and/or false claims.

While it is improtant to note that the more light a plant uses (and I'm talking about the normal plants we see every day) the more products of photosynthesis it can produce and then use. I need to open my biology book one day a re-read all of those once boring pages. Who would of thought that I would go back to them with great anticipation haha, my biology teacher would bloody hang me if she found out.

Anyway, the people that are for this method say that you can get much better veg growth than with a "typical" light schedule and while I cannot confirm that (my girl on this run suffered from a lot of stress because of moisture(?),being root bound and the dreaded case of being tended by a total noob) I can say that the growth hasn't been stunted in any way. On the contrary, the rate of growth hasn't changed in comparison to my previous grow that had a 18/6 cycle. And of course less light=less food, so that doesn't add up.

With that in mind, the amount of energy used by typical light schedules is just WASTED. With the GLR you can save up to 5h a day worth of energy comared to a 18/6 schedule. Damn, that's 5h a day, 7x5=35h a bloody week. That's a fuck ton of energy you can either have redirected to your pocket in the form of cash OR you can add in extra fans/air pumps for those growing hydro and then act like you just have a normal 18/6 cycle but with extra goodies. If I'm not mistaken the lights make up most of the electricity bill(?).

I'm still in the veg phase, so I cannot say anything about the flowering phase, although I'm interested to see it explode once switched.

So if anyone still has any doubts, then don't worry, it's not some mickey mouse shit that will cause your plants to die and you to suffer eternally in hell. It works, and while it may be a bit different than the 24/0, 20/4, 18/6, 12/12 everyone religiously follows, it works.

So you save a shit ton of money if using a lot of lamps, and can only get the same or even better results. So why the hell not? Yeah yeah, 90% of growers use the traditional schedules, but why not try something new? The phrase "if it ain't broken, don't fix it" is utter nonesense sometimes.

A little more than 3 weeks to go.

What light schedule are you using now?

Started flowering at 11/13 and reducing light by 30 mins every 2 weeks.

So you will be finishing up around 9/15 then?

YEPPER !
And a little drying and curing and.... a VERY Merry Christmas !
