exactly.....plus the life span of your bulb is consumed faster with 24/0

Run what you want until about 15/9, after that you'll get stretch and pre-flowering, I've used them all and settled on 20/4 for veg including clones/seedlings, but from time to time like summer I've gone down as far as 16/8 to either slow them down or deal with heat. When I have space available I'll use 14/10 for 7-10 days to pre-stretch and get them pre-flowering before the fins flip to 12/12. it's all good, just a matter of preference or situational, there is no consensus on veg times as you can see, everyone has their own opinion or preference.

17/7 is a judgment call dosn't really make much sense to hold a debate on the question as its really down to personal preference if you do 17/7 or 18/6....although if you do 17/7 over 8 weeks of vedge which is 64 days you save 64 hrs of electricity which is nearly 6 days...worth thinking about if electricity is an issue. as 17/7 and 18/6 are close enough to each other to probably not make any real difference to the vedge growth...so in conclusion yes do it if you cant afford to pay your electricity bill.....peace!!!

18/6 and then reduce a few min at a time over a week to 10 days til reaching 12/12.

I veg under 24 hr. light. I know it costs more but I don't have an area that I can give them total darkness in the veg area. I have grow under 18/6 and that was a good schedule.
I just find the plants get to the flowering size faster under 24 hr. light.
I let my plants get quite big because they yield way more when they are a big size in a 20 gallon pot of soil.

You don't need to give them "total darkness" in Veg. That's only important in Flower Stage.

It seemed that the bulbs woulnt last as long as 24/0

most electrical items fail; at start up and shut down so probably yes

when I veg I do it at 18/6, one good reason for the dark is when you want to flower a plant you use the same lights ON time as the plants are used to from the Veg cycle.
The plants show sex quicker in my own grow.
I started w 24/0 then after I started to learn about flowering,
I was taught that the plant has a memory and the resting state is a good thing.
Sure it's a weed it will grow in 24/0 but when you want to flip the plant to flower it will take longer If The plant has to Learn to sleep when 12/12 starts.

I did not know that ambient light could be allowed if you are giving plants a dark period during the veg stage. Thank you for the correction.
You're welcome, no problem. About 12 hours of uninterupted darkness is what's required to initiate / trigger the Flowering Stage. If those hours of darkness are interupted by sufficient light (a few times?) - or if the hours of uninterupted darkness aren't sufficient - the plant will be kicked back into Veg Stage.
If the plant is already in the Veg Stage; any additional light won't cause any traumatic shift, the plant will just "think"
"Umm, more light, cool!".
By the way, the need for "Complete Darkness" is an exageration. In nature plants are exposed to the light of the Full Moon on a regular basis. That is the threshold you need to stay under.

Actually yes 18-6 is standard however so was HID lightening, just because something was standard don’t mean it was correct nor room for improvement. No different than HID, paper towel method, light spectrum etc. It’s been determined that HID lights weren’t correct however that’s all we had available. It’s now been determined that natural sunlight colors (all the colors in the sun) is better for cannabis growth & production. Blue light for veg and red light for flower was not best optimal. Paper towel method for germination actually did more harm lowering germination rates by 31% vs soak in water until taproot exposed method which has a 98% germination rate. All the standard is now vacant right!! Truth is spring sun comes up 14 hours a day and darkness 10 hours a day. Toward September it goes to 12/12 cycle. Just after July which is 13/11 so u see the Sun is starting to go down earlier and more darkness increasing slowly. The cannabis plant should only be 14 hours of light and 10 hours of darkness during veg and 12/12 during flower. After 30 days sun is up 11/13 and end of Oct-Nov (during autumn) cycle is 10/14. This significantly triggers autumn and ripening. However growers thought increasing veg would grow more bud sites being more light but that’s not true. Plants grow during their night cycle, not their day cycle. But photosynthesis Collect’s it’s carbohydrates and inorganic nutrients during the day to utilize them during the night. Cannabis plants wilt after about 15 hours of light during veg. This is normal being in the wild plants are heading to bed but humans extended its playtime by 4 extra hours but plants only use about a extra hour (up to 2-hours for really healthy plants) of light and the other 2-3 hours the plant does use it. It droops its leafs downward and photosynthesis stops. Therefore useless light being utilized. Also, if a plant droops earlier than last few hours there is too much light plants get tired like humans. For best results change your veg cycle to 15-17 hours. Not 18 anymore.

for "Complete Darkness" is an exageration. In nature plants are exposed to the light of the Full Moon on a regular basis.
FALSE, Moon is not a light nor type of light. Light is a spectrum of wavelengths between 350-800 nanometers (nm). If the spectrum of energy does not register between those numbers or wavelengths it’s not light it’s a lunar illuminance, which is 128,000 times less than what sunlight provides within the nm wavelengths. Lunar illuminance does not carry enough energy to excite chlorophyll molecules. It’s not a light do not call it a light. When speaking to Medical students or using medical terminology you can’t use incorrect terminology then say “you know what I meant” when your called out. I just corrected a “Cardiac Heart Surgeon” doing a seminar teaching the important of registering to be a organ donor in which someone must die a certain way in order for their organs to be harvested and because of that it’s important of why we need more organ donors as 97% of deaths their organs can’t be used being they didn’t die a certain way. He then stated “a person must be brain dead in order to be an organ donor.” Technically, everyone in the cemetery or died was pronounced brain dead. He should have said in order to be a organ donor a person must be declared brain dead while on a ventilator prior to being pronounced brain dead. Therefore a donor must have died while they were on a ventilator so the machine may keep their organs alive being the brain is dead. If not on a ventilator when they died they can’t be placed on a ventilator later as the organs have already been deprived of oxygen.
You sir can’t call the Moon a light source if it’s not. The Moon regulates gravity and is a good source for animals that use gravity as a way of life support to hunt food. The Moon goes through Lunar cycles. That’s it. Gravity and Directional travel.

Why fight it juat look at DLI you are producing
