Reduces the stretch, causes faster flowering, causes faster finishing

I didnt know it had that many effects, very interesting!

Indeed.
It is when I consider vegging in one of my tents....i.e. 24 hours a day of
those expensive lights burning....that makes me think about alternatives.
Recall that I Veg under a rack of four T-8s and two HOT-5s. (236W all together)
I am running to the Hardware store for a simple timer.

Vegging under Cree Retro-fit streetlights, 150 watt draw each. but dim to 36 watts 5500K is the color temp.
I need a new timer, mine set for 7am and 7pm for flowering.
Its analog, but still it shouldnt vary by up to 7-8 minutes fast or slow on each cycle lol

They sell for hundreds of dollars each, but I got mine $25 each new on ebay.
Guy sells stuff from closed businesses and stuff.
He didnt know what he had.
The have a small fan that as you turn up or down the light it varies with it. Never gets past 80*F on the heatsink.

Wow, those sound awesome. I am sure that I'd like to know more about those. :0)
Hey Bass, do you work on Humidity at all?
I have always just liked my dry weather, but, with temps in the 80s,
I wonder what sort of improvement that I might see from raising my
very low RH a bit.
I have experience with humidifiers and without automatic control
they will drench the space that they are in.
I am thinking that using a bed of perlite, a la the passive technique
that some mushroom fruiting chambers use.
Here's the thing: I have no PM issues. Zero. PM is a *nightmare*
for so many of us. It *destroys* things in my yard....50' away....
Just wanting to consider my options.
I have burned through one of these....I might get another:

Also, I know the humidification tech that fits this needs......were mushrooms
needed either a fogger or the Kaz water-slapping model, this need might get
away with one of the wicking sponge types....

This is the sort of thing that I'd like to try:
But I would need a programmable timer to support it.
From here:
http://cannabisni.com/2101/grow-bigger-and-better-saving-30-50-percent-on-your-energy-cost
We can discuss the audrino as an idea....but I also want to consider
whether such a device is made for the industry and, of so, how much
they might go for.

My RH is usually very low as well except during parts of winter or rain.
I have a very hap hazard way of combating it.
My primitive method is just use a cool mist humidifier during veg if rh is under 45%
I watch it and see if i needs more or less and might add wet hand towels in veg area lol.
This is another area where the Arduino would be great.
It can control so many things at once if you know how to use it.
In flower I generally dont worry about humidity being low, but I do have 2 dehumidifies for when its over 55% and no sign of going down.

Do you think that method really does all that?This is the sort of thing that I'd like to try:

Faster veg, faster and more productive flower all while using less energy.
Sounds too good to be true, but might just be me being used to the regular way.
I thought LED was hype for several years also, but thats all I run now.
Also thought organic was going to be hard and low yielding, both for me at least arent true.

I need to see grows documented where these methods are implemented, and a side by side would be awesome!

I will be looking for grows using this lighting schedule.
I want to make sure sensitive strains dont hermie or other issues.

Another method I saw:
The Theory
The theory behind the 18 hour Day/Night cycle is that during a normal 24 hour light cycle plants will usually achieve high growth rates peaking at 100% capacity during the first 50 - 60% of the day. The growth rates will then diminish rapidly and the last 20 - 30% of the day achieves minimal growth. So by reducing the length of the day we are triggering an increased growth mode where the growth rates are at their peak for the majority of the day. This effectively achieves a very fast growth cycle with full yield potential.
NOTE: To achieve these incredible growth rates it is important to provide maximum light intensities and CO2 enriched conditions. The recommended lighting is 600W per square metre.
The Cycles
Vegetative Cycle - Lights ON 14 hoursLights OFF 4 hoursFlowering Cycle - Lights ON 6 hoursLights OFF 12 hoursThe Benefits
The growth achieved during an 18 hour cycle can be the equivalent to that achieved during a 24 hour cycle. So by running 18 hour cycles the same growth and yield can be achieved in 75% of the time.
Reduced day lengths also mean reduced power consumption. Grow more and use less power. Who can argue with that?
For example, an average crop grown from seed using a 24 hour day/night cycle will have a 4 weeks grow cycle and an 8 weeks flower cycle. This equates to 28 days @ 18 hours a day and 56 days @ 12 hours a day = 1176 hours of light over 12 weeks.
An accelerated crop using an 18 hour day/night cycle will achieve the same yields using a 3 week grow cycle and a 6 week flower cycle. This equates to 21 days @ 14 hours a day and 42 days @ 6 hours a day = 546 hours of light over 9 weeks resulting in a 40% reduction in power consumption and a 25% reduction in crop time.
