Is there optimal amount of light that you can give for photoperiod plants? 18/6 to 24 hours? And when to swap?

Calling people out for showing their plants? Really? I mean that only works when you actually grow yourself. I’m slightly worried that you may need some help based on your recent posts. I hope you find it.

i also posted my new light routine was 7-10-1-6. wonder if he thought i was serious about that too????? lulz
 
This thread got weird all of the sudden. I spend most of my time on one forum for autos and another for general 420 stuff. One draw for me is that RIU has a really good thread on Jack's 3-2-1 but you do throw a lot of elbows here. That's not a complaint, just an observation.

Anyway, I think the OP's bailed out and Cassie might end up being AWOL which is too bad because, she (I think that's correct) seems to have done more research than a lot of folks and that can be very helpful.

All the book reading is pointless without hands on experience its just words the speaker doesn't actually understand.

But that aside... you said last night somewhere that the dark period is not related to the light being off... Or words to that effect, can you please explain that one?

Agree about the words vs seeing the plant. Until you see a cannabis plant that's ready to harvest, it's really hard to describe what it looks like, even with excellent photos. The best I can do is add the word "fecund" but if you've never been pregnant or around a pregnant "person" that's a dead end.

Turn that around - "read the plant". That's meaningless. As a new grower, with no experience in growing plants, I can look at a plant all day and I understand exactly nothing about it. The written word was the greatest improvement in human knowledge ever. Without being able associate the "green pointy thing" to a picture that has a caption "leaf", I'm still ignorant about the plant.

The value of the details is that it allows me to associate what I see so that I can build an understanding of what's happening. That's how we create knowledge. Lacking knowing the underpinnings of why things are happening means that I'm not able to change the current environment to get the results that I want. In essence, chaos. No thanks. An understanding of why we are where we are today can help get what we want tomorrow. That's for me but I am under no illusions that's "the right way". It's just one way and one thing that's interesting to me is how grower's find their own "right way". It's sort of like Curly, one of the stars of City Slickers - "there's just one thing", he says but he never says what that is because that "one thing" is up to each of us to figure out.

Enuff of that.


Lights out ≠ the "dark cycle"//"dark period".

Best advice I can offer is that you Google the "Calvin cycle". I'm not trying to sell anything short but it's easy to get info on that, it's a really important part of how plants work, and my knowledge of plant bio is really thin. Before my three cannabis grows, the only thing I've grown is old (er). :-)

You know that's way too advances to even understand for a normal grower. I'm sure even the biggest growers have tested this topic a lot. I want to know how much root mass cannabis grows in different cycles (would mean more water) and how much that affects the cycle, like how much you can push your plants with light cycles to maximilize the grow and result? Is there any knowledge about those things? Would you need automatic lights for that so it would mimic the sun?

The thing i'm a veteran.

But i thought this forum had tigher rules and moderation. And on top of that good growers who can can share information from newbies to the most advanced growers? I guess there's assholes too who can't even go fight in their private chat. Where i must go the get information on topics without some idiots start fights but actually give real answers?

24 hrs of light will give you the best growth.

Are you talking about the tomato fruit? Or are you saying the plant itself won’t grow?

The plant will not grow under 24/7. Or rather it will grow for a while, but then it will start to have problems. There are a few special varieties, which can be grown under 24/7 lighting. I haven't tried growing them 24/7. It's just what I read, but the info should be accurate.
 
I used 24/0 years ago but found that 18/6 to be about the same. Igo 12/12 from seed now. The plants do not grow Half as fast as 24/0 but maybe 80% of no dark period.
