Why 18 hours works for me

[faithless]

Well great. I'm happy for you.

faithless Reviewed by faithless on 11-06-2006. Why 18 hours works for me O.K here are a few reasons to run your veg 18 hours instead of 24. 1. You can run 25% more wattage for the same money. (so a 250w on 24 will cost close to a 400 on 18). 2. In a sog or perp harvest where your veg is running constantly 24 or 18 will have no effect on yield though it will have a large impact on electricity consumption. 3. It is simply more natural for the plant. To be fair I will say that if you have to run the same light for veg and flower 24 may speed Rating: 5

My whole point was efficiency. And what i said was I dont think any 'expert' would claim more bud from 24 hours during the veg cycle.

No Emory is who im thinking of

This has already been covered very recently, posted by Anathema2121, you can probaly find this thread further down the page but here it is again.

And like I said, natural outdoor conditions are irrelevant to a plant grown indoors for #Number of generations :-




Check out this thread, it covers it pretty well http://boards.cannabis.com/showthread.php?t=79571

Cannabis plants do not need a rest period, unlike some plants. And as far as the "dark" reactions necessary for the completion of photosynthesis, there aren't any requiring darkness, just some not requiring the presense of light.

"Thanks Spunjah!

The main thing to keep in mind is that the indoor experience is not a replica of outdoors. The strains that are best suited for indoor growth have been bred and grown indoors for generations. Whether you grow in soil or hydro, under fluoros or HID, the only link between the indoor grower and the outdoor grower has to do with plant mechanics. Things like uptake of water and nutes, maturing, sexing. These are basics that exist in both worlds. For that matter, the production of sugars is basically the same in both worlds as well. It's just with the indoor world, we can control many more of the factors than the outdoor farmer. We choose when to go from a vegetative timetable to a flowering one. We decide on ALL the factors of a grow. Humidity, temperature, the works. Let's see an outdoor farmer grow his plants to full maturity in just 4 months.

Having said that, the objective of growing indoors has to be kept in mind when deciding whether to go 24/7 or 18/6. If you are trying to create a little piece of the outdoors indoors, then by all means, have a nighttime. You might want to hook up a high velocity fan and blow your plants over once a season to replicate a wind storm, and if you live in the north, perhaps a blast from a CO2 fire extinguisher would seem like frost. Obviously, that is not the point. The goal is the best, biggest crop in the least amount of time. Taking 6 hours a day in the dark means your plants lose 42 hours of growth each week. Why waste all that time when your plant could be photosynthesizing it's green butt off. Plants don't need REST. That's what is so amazing about them. Give them the right ingredients, and they do the rest."

Light cycle
by Ed Rosenthal

Marijuana plants continue to photosynthesize as long as there is light and their other needs are met. They do not need a rest period. Turning the light off for 25% of the day decreases growth rate by 25%. This is actually costly because it requires the plants to spend a longer time in the vegetative stage.

He is rite, the plant that is supplyed all its nutes it dosent need to rest it like a mechanical device that has full power and ideal conditions to operate, it dosent need to rest.

Oooo bad temper.

1. You can run 25% more wattage for the same money. (so a 250w on 24 will cost close to a 400 on 18).

Ed disagrees: "Turning the light off for 25% of the day decreases growth rate by 25%. This is actually costly because it requires the plants to spend a longer time in the vegetative stage."

2. In a sog or perp harvest where your veg is running constantly 24 or 18 will have no effect on yield though it will have a large impact on electricity consumption.

I believe Ed more than you, thanks a lot.

HAHAHAH i have to agree agin.... hes rite man, go do some research of the research done by the long time pros befor you go throwing your half cocked theorys around with your limited growing experiance LOL

[gmoney5ss]

Im not trying to argue with anyone on this topic, but i had my lights run 24/0 for a month now and just now started a 20/0 period.. and from my experience the plant seems to pick up alot of growth in its short dark period.. i dont want to get technical with all of you its just something i noticed, more like a break than rest and whether its been tested time in an time out you just never know how each individual will react to a little darkness, mine seem to pick up growth with 4 hours of dark and kinda gets them ready for the next 20 hours of light..

Just mildly theorizing, but perhaps it could be that they shoot up noticably after resting for some hours, but that their growth halted during their rest?

Faithless Im lovin the avatar, I have a beagle myself.. Do you have one aswell, or jus like the picture?

They are crazy dogs, they love to bark at anything that moves..

Also this thead has made me change my mind about my box, I beleive Im goin with 24/0 now.. Im gana be starting from a clone and want maximum root production so 24/0 would make sense right?
