So what does that mean mongo under 24 hrs looks like a bunch of clones these yours how long now in veg ??

No those are not mine. I made those for a bunch of patients. That was last year. Not sure how they ended up doing for them.

I will say it again, I flower my pure sativa under 11/13 so they will finish. Plants become accustomed to their light cycle. Any incremental light decrease will signal fall time for the plant. Never in my damn life did I say you can flower a plant under 18 hours of light. Taking a plant from 24/7 down to 18/6 will absolutely stress the plant for a couple weeks until it figures out what's going on. If Jorge Cervantes says running your lights 24/7 is optimal then he is wrong, wouldn't be the first time. DJ short and many others would disagree with Cervantes. Cervantes isn't a well respected breeder as far as I know.

I have tried both ways I am going by my own observations. Plants are sensitive to increase or decrease of light. My plants are used to 17/7 of light. When my clones go out to other growers who are at least 18 hours, plants have an increase in light and hit a growth spurt. If you decrease light they develop pistils in veg. That is my logic.

24 hr lighting has its purpose reverting a plant back to veg Faster , cloning one would think you know them ware house growers ??? if growth was even 10 percent better then 18 - 6 most would of done the change to 24 hr lighting 20 years ago lol have they ????
is this the case ?? i know i know everyone will say well it would cost to much so then it out weights the gains in growth lol
truth is 18 / 6 pretty much sums it up rather quickly and the best way to grow that is what it really comes down to not some shoe box grower running his plant under 24 hrs lol etc etc
would love to see a 5 week old from clone tree cause i can post them up but you will not find it
Bet if you looked most will be 1 - 2 week max and flip and even then there fucking midget plants

Well of we are talking just a matter of efficiency here I can see where 18/6 would allow you to save energy and get good growth at the same time.But to assume a c3 plant requires a dark period to grow roots and repair itself is pure speculation.There are plenty of examples of cannabis grown under 24hr light that have a good healthy root system and are vigorous and healthy.So again empirical evidence suggests a dark period isnt nessessary.At this point it seems like a matter of choice.

Replicating the tropics brings out the sativa in a sativa. Flowering on 11/13 and adding ultra violet light and a better light spectrum will help the plant express itself and bring out different qualities.

i like 18/ 6 HERE from a 3 " clone with 5 week veg start of week 7 with 24 hrs darkness prior to flip

here 2 week old clones after transplant so 3 " clone and what she looks like 13 - 14 days eventually looking like this in flower lol got to love `18 6

With everyone saying show scientific proof what i find ironic is believe it or not we are still learning what the plants are capable of and actually do ,, To be truth full and i see it all the time now science changing there views as science betters them selfs
Its only been last 10 years where they have gotton into the biology of plants in soils etc they have a hypothesis,, but again new things are found and changes made in text books etc
The real question is If somebody has some scientific evidence that plants grow faster in veg at 24/0 than 18/6 , I'd like to see it. Based on my experience I haven't noticed much of a difference
and i am pretty sure have grown in a much larger scale to actually have a say

And on last note a copy n paste
To simplify things, lets use an analogy. Try to think of a plant as a building… one constantly under construction. The plant needs raw materials, (fertilizers and water), and energy (light) in order to “build itself”. The raw materials are the “bricks and mortar” of the building. The energy is the workers, vehicles and power tools used to assemble the building.
The Plant is capable of storing some raw materials and some energy for use later, but the amount is limited...think of a warehouse and a battery.
* During the day, (Lights ON) the plant is collecting and storing light energy, and is using and storing raw materials. The plant is stockpiling raw material, and is charging it’s batteries… it is ALSO using raw materials and using the energy it is collecting. It’s building itself, literally putting itself together.
During the day however, the plant is not as efficient at building itself, as it is at night (lights OFF.) It can build itself, but not as quickly.
* While the lights are OFF, the plant is using energy and raw materials to build itself…. the plant is more efficiently using the raw materials that it stored during the day. The plant is better at transporting and assembling the raw materials.
The bad news: since there is no light energy, the plant must rely on energy it stored while the lights were ON (its stored energy). (Essentially, the plant is running on batteries, and using raw material from the warehouse.)
There is no light energy to collect. Since the plant needs energy to absorb more raw materials, it is easier for the plant to use raw materials that it stored during the day than it is to absorb raw materials through its roots.
* Although the plant IS capable of “doing it all” with the lights on, (Collect, store and use energy & raw materials) it does a better job of actually doing the work (using the energy and raw material) while the lights are out. During the dark however, it relies solely on its limited supply of stored energy and stored raw material.
One last thing to remember is the fact that a plant will always strive to maintain a balance between the size of its roots and the size of its canopy (Leaf mass.) The roots must be big enough to supply as much raw materials as the canopy can use, and the canopy must be big enough to provide the energy required to store those raw materials….
* Trim the roots on a healthy plant, and canopy growth will slow to a crawl until the roots have grown big enough to again support the canopy.
* Trim the TOP of a healthy plant, and root growth will slow similarly, until the canopy has grown big enough to again support the roots.
* If the plant is already in balance, the canopy and the roots will grow at the same rate.
If you actually measured them several times daily over several days, you’d notice that they actually DO get bigger at night, but roots and canopy at the same rate, unless either has been trimmed, and as long as the “batteries” hold out.

What strains are you running? Looks nice. I like watching my plants wake up when the light come on.

I'm asking for proof of any claims on either side of this argument because I don't think there is any convincing body of data for the record, and I feel too many claims are being made about botanical causation and trait desirability than there are data to support. There is data to support the idea that 24/0 is not harmful, and that more input (in the form of PPFD) indicates more output (in the form of vegetative growth) I have not seen the specific data as to the actual benefits of 24/0 photoperiod, so I'm drawing the line short of that. The whole point of all my ranting is "I don't know, and you don't either; please stop pretending you do."
Regardless of any of the above; this thread is comedy gold, so much disinformation and misinformation it will live for years!
@2ANONYMOUS Your shit looks tight, I'm not disrespecting you in any way, I'm just saying there's a lot we don't know. It seems we agree about that, but may draw the line in different places.

18/6 seems to be the industry standard. Many, many of the best breeders stay with 18/6. I will make everyone happy and say if you can't decide, run em 23/1.

I like that because both numbers are prime. I say we should only run ratios in which both numbers are prime:
23/1, 19/5, 17/7, 13/11, 11/13 are all acceptable. (obviously not 7/17, 5/19, and 1/23)
Non-prime numbers make plants shifty and nervous. /trollface

Feed with veg nutes on 12/12 and it will flower okay because veg nutes are typically around 5-4-3. If you flower under 5-1-1 you will notice a big difference. If you don't customize and utilize n-p-k ratios you lose yield.

This time of year(January)I run a 400w hps 24/7 in the veg room which has a flood and drain set up,the area is in the master bedroom,works great and offers up some needed heat.
When warmer temps arrive I switch to dirt and run the hps 16 hours and use the light from the window for the rest of the light needed to stay in veg.
