Why is 24 hrs light preferred over 16? Clones

[MedicalMike420]

I've heard that some people do go with 16. I just built a 2x4x4 box so I have a veg area, was gunna chop a plant down that's not doing great and use it for clones. I already have a 16/8 room going but it's going to 12/12 this week. What does no darkness do for the clones to grow roots? Does it make a difference

 

[covert222]

Clones can have darkness and it's fine I like 24 for veg cause plants seem to stretch in the dark

 

[saiyaneye]

Sometimes people want stretch (LST and Mainlining).

I prefer 24hr I feel that it seems like it grows quicker, however that is highly debatable. Plus you just plug your lights in and don't have to worry about a timer.

No one really knows, I dont like 24 because of how much energy it uses, seems unnecessary. What happened to the plant thats not doing good, are you going to chop the entire plant? I didnt really get that

It had root rot and it might be coming back, I also just want all soil ATM and it's in hydro. I don't want it to die I need to flower out the others things we getting too big, this way I can get a second go. I also have cuts off the same plant that r ready to flower. It's from now 1 and still I veg because of problems

I have better luck and speed with clones doing 24. I also veg that way.

It can be stressful on the young seedlings if the temp drops too low at night, so I prefer to run 24/0 until they are established, just to maintain that consistent temp, then I introduce a dark cycle.... typically after a week or so.

I's a minor cost to run a few CFL's or T5's an extra 6 hours/day

The theory goes that C3 plants, plants that grow and live by photosynthesis don't need a dark period

so now newbies, see above, run their babes 24 hours a day non stop, for all types of newb-ish reasons(see above)

the fact that only in the most remote places on earth does such places exist, does not bother these boys

the fact that cannabis don't or can't grow in the remote places ..likewize

but they are all ways back every year posting in the 'Marijuana Plant Problems' subforum if not here elsewhere,

the point being, grow your plants the best you can,

often the best growers are those that cared for pets even plants before they took to cannabis

every living creature needs a break including your plants, lets see you guys go 24/7 for 60 days ..?

this is not to be confused with anthropomorphism, the bit where humans name their plants and other emotive causes

https://en.wikipedia.org/wiki/Anthropomorphism

some could say its very 'merican of you to do this, others would dispute this ..

I understand the thought process for the break etc... I used to do 18/6 but I have seen no advantage other than small amount it saves on electricity. So 24 works well for me and my ladies. If they gave me a reason to give em some sleep I would lol.

what advantages do you see by using 24/0

 

[Redishx]

I run my lights 24/7 right now as well, I'm curious to see what advantages/disadvantages a "sleep" schedule is, besides saving on electric. Heat isn't a problem in my tent so I guess we can rule out "cooldown" times as well.

24hrs provides constant energy with clones since your plants will spend no time using energy it stores to use while in a dark period. Its kinda like life support, you don't pull the plug unless they are gonna die or can survive on their own.

 

[hyroot]

They won't use that energy unless they sleep aka phytochrome state.

Read the link I posted up above. There's a section on day and night for plants

If you run 24/0 when your plants go into flower they will be stressed out.

I have done 18/6, 20/4 , 22/2 and 24/0. Other than the stress , The only difference I ever saw was 18 /6 stretched more on indica doms. 24/0 had too close of nodes.

You can manipulate stretch with light utilizing 730nm IR and 660 nm deep red light.

I seem to always have better success doing 24hrs, when i do dark periods they end up a lil droopy when the light comes back on. but they perk back up. But as far as stress, clones are gonna stress anyway due to the fact they have no roots, but i don't recommend 24/7 veg.

That's them sleeping and using the energy they've built up all day for other processes. So they energy used reaching towards the light is essentially useless. When he lights come on, they go back into collect and store mode and reach back for the lights. They're not droopy in the same sense as over/under watering when it's dark. It's not a bad thing.

I agree with you, but 24 hours for a 3-7 days isn't so harmful, nor is a few hours of darkness. Ive had clones that molded and died in the dark(og kush) just from a few hours though, so i just like them to get some legs under them before i let them use the energy they have. IMO conditions and strain plays a big role, i had some bad seed mid clones that were resilient,while other strains are extremely hard to clone. I do what my plants like.

24 hours isn't necessarily bad. It just forces your plants to overwork to do its sleep processes while the lights are on. Either way works. Mostly preference. I keep clones 24/0 but as soon as they have roots they swap to 18/6

That's the way to do it, considering cloning nor 24/0 is natural. After that you could go straight 12/12 or continue vegging.

Have you tested the repair and growth times of mother plants on those different light schedules. Like for instance if one takes a 50 flat of cuts and wants to make another flat as soon as that mother plant grows back. Do you think 18/6 or 24/0 gets the mother back any faster or any slower?
