Even your autos will perform better on 18/6 you will be happier with end productWell with autos that's what I do. So I was wondering if I could do the same with photo's during veg in an attempt to speed up growth in the early stage and then flip to 12/12 for flower.
Again I've never grown photo's hence the question.
Yeah I think many have shown this to be achievable and very effective. Healthy plants can do this and handle a high light intensity and imo at 16-18hr light is a good place to be for overall healthy veg and happy plants.I agree. I try to hit the sweet spot at 16 hrs though.
Not really, you can grow plants for years so X calculation doesn't work X in Auto's No X in Photo'sI'm just asking about it mathematically. A plant can take x light before shriveling up and dying. If you spread x out over whatever hours, it's still x. So you have a light that is said to produce that x over y hours at z power, so to keep x you have to turn down z if you turn up y, you can't have x +1, that's death.
Think he is referring to the daily values and light saturation points but I could be wrongNot really, you can grow plants for years so X calculation doesn't work X in Auto's No X in Photo's
Well she doesn't say how long a period is needed and she's talking 24hrs through the entire veg period. She agrees that it helps growth by 20% and for a few weeks once the plant is established and healthy extending the light cycle for a few weeks to 20 -24 will give more growth and not harm her if I go back to 18 / 6 a few weeks before I flip.Like I was saying the plants perform different functions in light on and off. Part of which is included in this video. Yes it works and yes you may see more growth but only if your not hitting a good DLI. This is why in flower we need such intense lighting to hit the DLI while in veg we need less. For that reason if you have med to low lighting your probably going to do better with auto's because your able to provide a higher DLI.
I'll only partly agree with that. I was in the lighting biz for years & lights that get turned on and off burn out faster. Some old stairwell lights will last 20 years without being turned off they just get dimmer and get funky colors to them. The damage gets done in the heating up and cooling down. I'm no nothing of this new led / cob lighting but ballast's , tubes and transformers last a long time without burning out running 24/7I like 20-4 in my winter climate for veg. Good for the heat, After week 4 I go 18-6.
no lights are designed to run around the clock. Hard on equipment, and electric waste. Plus the girls respond best with a 4-6 hour rest.
I wouldnt say she agrees but she doesn't dispute it... again it about the DLI and photosaturation points. You can't just make a blanket statement of hrs of light without including the intensity of that light... thats why she didn't dispute it. It MAY produce more growth but that's dependent on the intensity given. If you increase the intensity over a shorter period to achieve the SAME DLI then you definitely not going to see a 20% increase to growth.Well she doesn't say how long a period is needed and she's talking 24hrs through the entire veg period.

I saw a YT clip showing 18/6 was the light dark cycle with the best results compared to any other, .....Everyone is an expert on YT so I take it all with a grain of salt.
I promise you if you give a plant 24/0 of my intensity in flower you will cook your plants.. its not as simple as hrs on or off. It MUST be taking intensity into account as well as durationI'll only partly agree with that. I was in the lighting biz for years & lights that get turned on and off burn out faster.

Ive never had or seen a light of any kindI'll only partly agree with that. I was in the lighting biz for years & lights that get turned on and off burn out faster.

Power Bill as said ......Ive never had or seen a light of any kind
Last 20years running 24-7.
I also don't live on the moon.
can you veg around the clock. Sure.
try it for yourself, Many have. Most pros settle on 18-6 for various reasons.
Yup that's one reason.... but again if you have to run more power to run a lower light on time are you saving?Power Bill as said ......

Exactly... higher the light the less intensity.. move those lights a foot away and see how they respond...I disagree. I have seen big grows with ceilings covered in 1000w metal halides vegging 24/0 with big healthy plants and fan leaves that could cover your head.
those rooms have more light than your one led lamp.
And dr. Bugby said in his videos that he has not reached the max intensity or dli for cannabis and with co2 they can take even more than the high powered new led
Again intensity is a must here... can't just pick one element and ignore the others.maybe last few years but almost all commercial growers I have met in over 30 years veg 24 hrs. Faster crop turnover equals more profit.
Also he did not make that statement on 24/0 AFAIK... also AFAIK he does not grow under 24/0 either.Exactly... higher the light the less intensity.. move those lights a foot away and see how they respond...
Well there is some evidence showing around 65DLI.
But there is a difference in light saturation point and photosynthetic rate saturation and 100% studies to show that as we get closer the photosynthetic rates diminish
