18/6 vs. 24/7

I've been told to have the lights 24/7 in veg. but some say I should have them 18/6.

What's the difference? Isn't it good to just give them as much ligth as possible before I start flowering?

The diff is that you save some money w/ 18/6. The growth is about equal. For optimal growth put them at 20/4. We had this debate some months back, ill find you the link. Lamp

here ya go; https://www.rollitup.org/general-marijuana-growing/161825-24-hr-lighting-versus-18-a.html

According to the growing bible, less light per day can encourage females

I do 18/6 to save money. I used to do 24/7 but it made no difference.

Plant will grow faster then the root's some say.I used it for a long time and for me it good, I grow in a small place so i get big fan leave the bean the plant at flowering time i can remove some fan and still get some good bud's. i just clone a dieing plant and one that was next to her is about 4 week's and it 3 1/2' fat at the top . just saying what your set up like.

hey can my plants bud whit out using nutriens????im using floranova but i just wanted to know cuz it been 2 weeks and nothing no hairs no balls wats going on ?????

I have heard that 12/12 during sprout encourages more females, im sure less light also does, good point.

Yes, it will not be at it best unless your growing outdoor's

I don't think you will find any real difference except difference of opinion. Just do what you are happy with and don't worry about it. You'll be fine either way.

wow it's actually been a few days since someone asked this, a new record!

simulate nature, plants need rest.

Listen to smokingherb, Hes a smart guy. Go with 20/4 all long time growers seem to think that 20/4 is the best. There is no diff in 18/6 or 24/0 Just a change in power bill. If you go to the link i posted at the top of the thread, this thread could have been skipped. This question gets asked alot. And there is only one expirement to go by. And in that study 20/4 worked the best by something like 15%. Thats quite a bit. Lamp

besides the obvious saving money. I am a firm believer that every plant needs at least a short dark period everyday. I use 18/6, because plants grow most at first light, my plants under 24 hr grew much slower than the same clones under 18/6. It makes sense, theres no time for the plant to rest to store nutes, and adds much stress to a never relieved plant. Much debate, but there shouldnt be, dark periods are essential to maximize growth of the plant

i agree with the 20/4, 4 hours of dark is plenty ..

Yeah I agree that some rest for the childern will be best for them. All living things needs rest?

I just recently switched form 24hr to 18/6 for rest/stress benifits.
