i couldn't find a timer at their site sandman

The software is the timer. They sell a relay controlled outlet that the software will tell when to apply power to and when to turn it off...

Rapp, I'm not sure where you are located, but you can get a digital timer that can have something like 74 on/off ( covers a whole week as well, with each day you COULD set different cycles if you wanted) cycles added to it,, they're hella nice, an cheap too ( like $17.99 i believe is what i got mine for at HomeDepot) :chin: let me see if i got a pic of mine still, give you an idea as to what to look for... nope, no pic of it in my gallery ( musta deleted it) but anyways yeah,, go to HomeDepot if you can,,, here's a link to the Home depot site, showing the timer tho :wink:

I believe in the thread CosmicBadBoy did, he had figured a cycle that was basically an 18hour 15 minutes cycle, that allowed him to set the timer in repeatable pattern, without having to adjust it weekly.

That's a good timer Cali, but I'd get the model for higher wattages - I believe it's the water heater timer. That one you posted was only 500 watts. But yeah, the principle is the same, and you're right, it is a good timer.

you just need to get a 7 day programable digital timer with at least 18 programable events. Most have a lot more than that. Then all you need to do is program the schedule into the timer. It should take all of 5 mins to do it and the timer should cost anywhere from 18.00 to 35.00 depending on where you get it.

I got the schedule off the advanced site.

1 ON Sun 12:00pm
1 OFF Sun 6:40pm

2 ON Mon 6:40am
2 OFF Mon 1:20pm

3 ON Tue 1:20am
3 OFF Tue 8:00am

4 ON Tue 8:00pm
4 OFF Wed 2:40am

5 ON Wed 2:40pm
5 OFF Wed 9:20pm

6 ON Thu 9:20am
6 OFF Thu 4:00pm

7 ON Fri 4:00am
7 OFF Fri 10:40am

Firstly this is a crock of bullshit,
and anyone that knows anything about how plants work will tell you so.

The manufacturer of that piece of equipment is just trying to sell you expensive shit that is not needed.

Anything less than 18 hours of darkness followed by 6 hours of darkness in veg Will shorten the crop times that is true.
However it will also cause the plant alot of stress and wont give it enough time to heal itself from the stress.
So although you will get shorter times it will be a greatly reduced Yeild, the plants will suffer from stress and in turn will be alot easier to be effected by the stress it will be under.

You guys do what you want to do, but 18/6 is the best lighting schedule for the plant. If you fuck with these times you WILL get more hermis, and also sick plants.

The plants do most of their work during the dark period, however it needs the full 18 hours of light to store enough energy to let the plant do its thing.

You may get faster crops, but you yeild will be alot lower and in turn your wasting more power, as the extra yeilds would more than pay for the longer lighting times.

But hey dont let me stop you turning your plants hermi, wasting money on equipment that stresses your plants and lowering your yeild.

if you want faster crop turn around use that money on a c02 system.

Some people will believe anything, and as long as theres suckers out there. People will sell them shit that doesnt do what its supposed to.

FERENGI?
have you ever even TRIED anything like this? I mean really tried it? not just spouting things you THINK you "know so well" . and hey,, just because this was an artical about a piece of grow equiptment, do you Seriously think someone can't do the Same thing with their Existing lighting/timers? Give me a break buddy..
Let these adventurous growers try this lighting schedual, and view the results.. if you're right, it will be shown,THEN you can gloat about what you "know",, and if you're wrong, That too will be shown..... YOU don't have to do anything, cept shut-up and watch.... and try not to be so pompous,,,

Yes, I have treid this method and a few other strange things.
Im actually in the process of trying to find my digital timer to gift to Rattrap so that he can try it himself.

I did have pics on OG of my experiments.

I wont say I know something unless I do infact KNOW it.

LMAO Ferangi,,, well at least you have picked the right Avatar for yourself :tongue: pretty fitting..

But hey, I still am interested in this little expierement, whatever the outcome. So good luck to you Nite ( an whomever else may try this method of growing):chin: with different genetics being tried, the outcome possibly could be different from yours Ferengi :wink: but we'll see

There are so many vairables where other growers can stuff up that i think giving this experement a go would be worth it tho perhaps with only a test run of 1 or 2 clones might be more sensible. I'll have to see if i can knock up a quick 2 plant chamber to do a test in.

Hey if someones got a spare grow space, then I t cant hurt to try new things out.
I used to use my built in rode for my buds and a 400 in a portable wardrobe use to play with the plants and see what happens.

just because my experimants didnt work, dones really mean it wont work at all.
It just means it didint for for me in my enviroment.

Im interested to hear from anyone that does this.

:)
and Wikid, good too meet ya :)

I'm planning on doing it as soon as I get into my permanent room, probably 2.5 months from now

yeah i'm planning on running a test grow too as soon as i can get a test room setup. Best bet vhghost is keep an eye on this thread, i'm sure anyone here doing a trial will notify peeps in this thread.

Hi Guys,

I'm just brand new to ICmag forum, and I would just like to give you this link to a test grow with a 6h40 ON/12h OFF flowering test:
http://www.advancednutrientsmedical.ca/forums/showthread.php?t=9819&page=1&pp=15

But I wanna say that:
-Cannabis is a C4 plant so there is no point in saying that it cannot exploit a full 12h light cycle.
-A study by J.R. VALLE show that diminushing light to 10h of light instead of 12h , will also diminish the THC content by more than a half. So, you can expect an even more important diminution with a 6h40light cycle of the cannabiboids content
Here is a link to an abstract of the study:
http://www.unodc.org/unodc/bulletin/bulletin_1978-01-01_1_page008.html

But nevertheless, it can be an interesting cycle if you wanna speed up your flowering




Cheers

Hey Azra,
Thanks for the links. I've seen the first one before but the 2nd other one was VERY interesting! Thats the sort of scientific study we really needed for this topic. Kind of kills the idea for me. Tho it might still be good for veg periods. As most peeps know, when growing from seed if u want to get the most out of your plants they need a good veg period. i've found in my experence that to be around 7-8 weeks before the plants have reached maturity. Using an 14/4 veg period would mean u could get an 8 week veg period in just 6 weeks. Also with the same shortened day for your veg period u'd be saving 112 hours of lighting. Thats nothing to be sneezed at!
