If your veg light is especially dim, there might some problems with 16/8. You could have a DLI that's low enough to trigger bloom when they hit maturity.

But otherwise, I'd go with a guy that knows fershure, aka Duggan. :)

There's something about light cycle and intensity that gets overlooked.

We run 18/6 or 20/4 in veg, and we run 12/12 or 11/13 in bloom ... and we know that the plant needs more light intensity in bloom ...

But a big part of that is something called Daily Light Integral (DLI). The light requirement is actually the total for the day. DLI = intensity x duration. A sunny morning and a cloudy afternoon is equal to a partly cloudy day.

So when we cut daylight hours, we have to boost intensity. :)

It's not an ironclad rule, but it's a big part of the need for more light in bloom. So in veg, we only need 60% of the intensity we need for bloom. But we're also running that lower intensity for more hours per day. 18 hours @ 25 watts/sqft = 450. 11 hours @ 40 watts/sqft = 440. :)

So, anyway, think of autos that way. All they need is the light - doesn't matter much how they get it.

So when bleached tops occur it's because of too long of an exposure to an intense light not necessarily the power of the light?

Woohsah brother, hit this :passitleft:
 
Our plants need more than 12 hrs of contiuous uninterupted darkness to trigger a bloom response.There is a chemical in our plants that need that darkness to build to a critical level..to trigger flowering. If that dark period is close to....or more than 12 hrs....this chemical will reach that critical level and bloom will commence. If this dark time is interupted with a bright light ,that chemical is destroyed and vegging will resume.You all know that though ...right!
The only reason behind using an 18/6 veg cycle was because everyone thought the extra hrs of light would enhance more growth....it DOES NOT!
So why waste money...run 16/8.. .....hope this helps.
Have a great day gang!

I have my far red pucks that come on at lights out for 20 minutes or so but thinking of setting it to
come on for 15 minutes every hour at lights out, I find myself checking things at lights out and have
green lights for those times BUT want to make sure they are not stopping the change over.

I cant think of a reason this wont be a good idea but wanted to throw it out in case the
EXPERTS here need to set me straight ;)

119...you dont believe me????
When i said 16 /8 is just as good ..or better than 18/6 did you think i was faking it? I use those hrs cuz when your running a lot of wattage it saves you money.
Never mind....do what ya want....im just having a bad day!!!

Nope nope, come on now Duggs if course I believe you my man! I just like hearing others opinions and anecdotal experiences, love seeing how people articulate and such. No offense was intended brother, and i plan on leaving the veg light 16/8. Was just curious on Grays thoughts on the subject. Please don’t think you waste time on me when giving advice or tips. I take it all in, file it away, make notes etc...

Hope your day get better Duggs...:passitleft:

This last grow I could only get them to 1.75 days between water, thats when I started to notice
the same issues. Very Hard to keep up with the cycle and did not want to loss the growth or stall
the girls.

Thanks Gazoo, that’s good to know. I’ll need to up pot soon or she’ll be going down hill! Good to know I’m not the only one having trouble getting them to daily feedings.

Thanks Gray, I should be good... running a QB at around 85 watts... in an 18”x18” space

Gazoo...are you trying to stop or delay bloom?

Ya....just having a bad day is all.When i feel like this i usually stay away from here for obvious reasons but those few posts just frustrated me is all.
Maybe there is a grower out there with lots of time and extra space that could prove my words.....like running two identical set ups ...one with 18 hours....and one with only 16......just to see for yourselves. 119.....16 hrs of light is plenty to NOT allow that chemical to reach a critical level to trigger bloom.
Sometimes growing unstable genetics ...or a wonky plant will give you doubts.I had one of my Devils Carnival throw out lots of pistils under 16 hrs.....but that was very , very UNSTABLE. That was the only time that has happened to me running 16/8. Do ya'l remember those weird behaving plants?
Its in that journal...in my sig.
As our plants mature and get some age and size to them , they will start to show more pre- flowers at some nodes but WILL NOT go into full flowering mode if the lights are on for 16 hrs.
Im not sure what the actual limit is but as i said...just like in nature...when solstice approaches and the dark period gets longer and longer you will start to see more and more flowers...until that critical level is reached...then full bloom will commence.

Thanks for checking Duggs

No I want FLOWER (Not having any issues) just dont want to cause a Re-Veg when I
open the door and very little but still SOME DAY LIGHT gets flashed. The far red will
stop the change back and was thinking having the FAR-RED come on for a time each
hour should cancel out any low level light that gets into the tent
 
Gazoo...what i do is during the dark period....which is during the day ,when im at work...they receive absolutely zero light from any source.This is..as you know is very important. Gazoo...why are you messin with them during their dark period? Try and leave them alone....adding light like opening up a door during that period is flirtin with disaster. Save all the work ,for when the lights are on and all that far red puck stuff wouldnt apply. If possible we should all be running our systems at night anyhow...while we're at home.....either chillin or in bed. Safer and cheaper that way.
When im at work my system is off! I really like it that way.When i pull into my driveway after work ...my system is just coming on....for 11/13....So they...the lights...are on from 4pm until 3 am.When i get up for work and am ready to leave...i take a look ...just to make sure everything is off..as it should be.
Cheers

Thanks Duggs

You are absolutely correct I wish I could stay out during light out (9am to 10pm) but I have some remote
humidity/temp sensors I can monitor from upstairs and DONT have any AUTO environmental control so
I find myself having to go and adjust the HUMIDIFIERS and FANS to keep it all within limits.
 
Bahhh,..limits smimits...you mean your enviro fluxuates that much...omg bud! I have none of that fancy equipment...why...cuz i don't need it..and neither do you. If the temps are within 70-90 and the RH is between 45 and 65 leave everything alone.

Man.. and here I am over here trying not to freak about my temps around 82-84...
Its weird... I put up that new tent thats almost 8' tall... kinda figured with more head room for the lights and the filter... more space all round... figured it would actually be a bit cooler. I was wrong, actually since it takes up so much space in that closet, now there is less airflow around the tent... so the closet holds more of the heat from the tent. To be fair, my house this time of year is always 79f so thats not a huge jump 4-5 degrees f. If I could afford to keep it cooler I would keep it around 76.

It is funny though Duggs... although you haver told me this same thing before I still have this deep urge to freak if my temps get above 80. I know your room gets hot at times, and your plants are always awesome! Nuff said!

Ya tbh 119 , 82-85 F is just about perfect ! Certainly 82 is absolutely nothing to worry about. If i was to say what MY perfect temps are , they would be 72 lights off and 85 , lights on. That is a differential of 13 degrees...just about perrrfect! IMO of course. Right now...these days mine are still a little warm at 72 -88F. As i type this...i just checked...it's 84 F right now. No worries.:passitleft:

Nice... good to know! I will worry no more, thank you...

Thats the stuff 119...lets worry about other shit.....lol...like our women... and how to keep them satisfied and or happy.
Now that's a worry...lmfao!:passitleft:

You just need to go ahead and install some cameras so you can just look at them through your phone. Sure there is something you could use to monitor all the rh temps on the phone too. You may have thought of this already, if not sorry for kicking your ocd into overdrive! :laugh:
