24/7 how long is too long.

I've recently heard that if your light period in veg (24/7) is on for too long that the plants will show stress in bloom. So I'm wondering how long is too long? For me from seed usually the veg is from 47-52 days, from clone it's less.

Have you ever gone 47-52 days being up for 24 hrs?
Your plants need to rest just as much as you do. Look into 20/4, 18/6, or 16/8 cycles

Yeah I like 16/8 but my associate prefers 18/6.

What I'm sayn is what's the norm for 24/7? I use to give em 24/7 for just like 2 weeks then 16/8.

24/7 isn't norm no matter what in my opinion. Your best off doing16/8 or 18/6 in my opinion from the get go

I have this Royal Cookie on 24/7 for 35 days now. Before




and now



I was going to flip her tomorrow but she going in a 10 gal smarty. I don't want to stress her.

I agree. I need @ least 8 hours myself.

That looks like very little growth for a month of veg

That plant tripled if not quadrupled in size. It's the green bag.

This is a result from 11+ hours direct sunlight and 12 + hours of 1K nitelight.

Well I went 24/7 for 52 days from seed, here's a pic, on day 52 they were 22 inches tall and 28 inches wide.

Now that's what I'm talking about. Are those 10 gal? Post full size if you want dude.

Also do you see any stress in flower after a long haul of 24/7?

they flower faster but stretch more when going from 24/0 to 12/12, my own personal experience from multiple grows working this way.

i only have my lights go out in veg if i am battling temperatures. i prefer 24/0 over all other schedules i have tried, i feel it gives the best growth.

24/0 is the way to go IMO for veg. faster growth and closer internode spacing.

24/0 is no more unusual than 20/4 or 18/6 to those who argue against it. people need sleep, cannabis does not.

I herd that the only reasoning behind them needing "sleep" is to develop roots during the night cycle..

I run my veg room 24/0 I was thinking of 18/6 only because it's getting hot the extra 6 hours off can help from 11a to 3p prime time sun time

having done DWC with 24/0, I can assure you they grow huge roots without a dark phase.

24/0 vs 18/6. = bigger plants or more mature plants. Both will go into flowering just fine.

24/0 Is the way to go.
IMO they get bigger before switching to 12/12.
Not one of my plants ever told me that they needed a rest...

I'm using 7 gallon smart pots, I see absolutely no stress when I switch to 12/12, and the stretch is looking pretty normal so far, they were 22 inches before I put them into flowering and now they are 32 inches, here's a current pic from two days ago 19 days into flowering.
