What is the best lighting cycle for autos?

I chose 18/6 mainly because I go to bed at 12 and get up at 6a. The grow is in my bedroom closet with loads of light leakage (until my tent comes in). So mine is a matter of convenience. BUT, then again, transpiration/osmosis occurs during the dark cycle (and other processes as well) so it makes sense to keep them healthy and stress free. Now that's NOT to say 24/0 is a bad thing, just saying that a period of dark IS better for the plant. It might also effect final yield if the plant is stressed going into flowering.
"Plants need light to photosynthesize, but darkness is just as important to give a plant time to convert photosynthesized nutrients into plant growth."

I'm a past photo grower, but I suspect even autos would benefit from at least some dark cycle.

The coolest thing about the auto,

You will get weed whatever light cycle you use!!!!
the best light cycle for an autoflower is......
whatever is best for you!
WORD.

defenetly 20/4 I don't care whats said every plant needs some time to work in the dark to do what they do.-----------I have a question for u ,does anybody know if u can clip some bottom and side sugers to thin ouy my three skunk bushes cant find answer anywhere thx and good growin!!!

do not stress

Yes there is a perfect light cycle for autoflowers.
This post is a very good litmus to that question. the variables of conditions seem to be the determining factor in end result.
I have found that 20/4 works for me.
As new growers we come to this site and seek knowledge from experienced and versed growers . I always hit this site to ask the stupid questions.
(yes there is such thing as a stupid ?) i ask them all the time.
its what keeps my room GREEN!!!!
 
Salutations Joedirt,

The coolest thing about the auto... ...the best light cycle... ...whatever is best for you!

If i could ever have used a closed structure then alternate options like the GLR schedule would have inspired me some experiments similar to using 14 hours of illumination and 4 hours of darkness, or maybe 16-2 or 12-6, which in all those cases will result in 18 hour days instead of 24 as on Earth... Why? Because such a daily gain of 25 % on gardening time would ultimately translate as 60 days instead of 80, for example. Well, if that theory makes sense that is.

:grin:

It could mean Sativas instead of Indicas, etc. Now, what if the life cycle duration is relatively short already? Something done in 52 days would only require 39 (5 weeks & 4 days)... Imagine!

:cool:

But my actual cultivation space happens to be an open prototyping platform synchronized to sunlight rythm. So this means i must stop using it when the winter season arrives, because i prefer to avoid ice formation on my window sill (as it turns out that's how i can vent out heat relatively economically)!...

Ideally i'd want to start a 1st session in April, never past July i'd say. Consequently i'd have to satisfy with 3 plants each 39 days, from April to July for example. I believe 14-4 would make a suitable trade-off, so lets suppose each plant provides 32 g (dry) under these conditions... My guess is this would represent ~4 pipe bowls daily (each pipe bowl holds 125 mg)...

So yes, "autos" are cool and self-sufficiency sounds cool too, even if it would only support recreational consumption.

:peace:
 
I just don't want to experiment with my 1st grow, I want to harvest it as soon as possible, without destroying potency, of course, but just suggesting. This might be a good idea unless the plant has some divine connection to earth cycles and moon cycle and it feels it is being cheated and freaks out.

But as soon as I have already posted my idea, I would like to ask an offtopic stupid question, here is my grow, 21 day for the bigger and 19 for smaller plants from seeding, aren't they too small for such a long period? Thnks guys!

By the way, that little thing down there on the 1st photo is an orgonite it literally recycles disharmonic electro-magnetic impulses made by electric appliances such as TVs Wi-Fi and else. Some say they prevent plants from growing fully healthy. And I also read mantras for them sometimes. I had a friend who told me a story about meeting a strange old man in his 90's who was growing and smoking from young age and he told that if you take the plant outside and put it under moonlight for 3 days of full moon and read mantras at that time the potency will increase threefold at least. I am serious, not joking, he smoked what that man had and was knocked out for the whole day. Just thought maybe someone would want to try it. I am doing this definitely.

I like to use 18/6, but I grow different strains together all the time. I have had some strains , like Spyder, that can do just fine under 24, but I've had others that didn't quite want to flower under 24, but when I reduced the light, and gave them some night time, the buds took off. Plus I also grow photos, so having an area with 18/6, I can grow all my autos & photo seedlings just fine with no troubles.
