What is the.........!

What is the difference between 18-6 and 12-12 duing veg. in quality or in other things.

well you can not have a 12/12 light cycle during veg. stage because when you turn your lights to 12/12 that is what triggers the flowering stage

by the way 18/6 is the way almost everyone goes, unless they are doing 24/0 which alot people will tell you is dumb

Yea Has Anyone Ever Ran A Test With 18/6 And 24/0 Lighting To See If 24/0 Lighting Actually Does Have A Purpose And Isn't Just Wasting Money And Electricity?

What Do You Use Smkpt?

I Think I Might Run A Test On That Sometime!!

i usally go 18/6 or 16/8 never gone 24hrs. ive read on this site that 24/0 will give you more males, dont know the validity of this but ill pass it on.

Your plants need the dark period... Does the sun shine for 24 hours a day?

I went for 12-12 from veg. to flowering it's doing well but I'am wondering about the diference.

What dont you understand? Its simple if you start with 12/12 your plants will never actually grow right they will be put into immediate flowering mode. at least run a couple weeks with 18/6.

You're a little confused here is all buddy.

18/6 is the light requirement to grow in the vegetative state.

12/12 is the light requirement to grow in the flowering stage.

While it is possible to start growing a plant under 12/12 from the getgo, it will still veg for a short period of time, out of pure neccessity, than go into flower, yeild and size of course will be stunted.

A good rule of thumb for an indoor grower, looking to maximize, time vs space vs light is to grow for about 1 month, 12" in height, and atleast 5-6 nodes, in vegatative growth, than switch to 12/12 to start the flowering cycle. FLowering should take from 9 to 12 weeks depending on strain and other factors.
I hope this helps ya!
Peace

I'm currently growing under 24/0 my first plant veged like this has just recently gone into my flowering room. The plant grew at the same rate as ones i previously grew under 18/6 and the sex was determined today as female. both 18/6 and 24/0 seem to work the same to me but you sould probably go with 18/6 to save power.

BTW does anybody know if changing the light cycle from 24/0 to 18/6 will trigger preflowers or stunt my plants?

i ves 24 hours because i am only using 40 watts to keep my mothers in veg and from there they get cloned and go directly to 12/12 from aeroponics. for 40 watts my hydro barely budges. but the good news is i don't have to give up any rooms for dark period and i can hang with my moms 24/7 if i like. It's more fun being able to smoke weed and hang with my mother plants then to let them sleep.

whackbag if your smoking around your plant, STOP smoke will harm your plants
