24/0 vs. 18/6 debate is over!!!!

i used to veg under 24/0, but tested each 24/0,22/2,20/4, and 18/6.. when growing from seed best female to male ratio was always best under the 18/6 light sced.. clones root just as fast under 18/6 as any other light sced... i stick with 18/6 now,, saves a bit on electric costs, and plants are healthy as ever.. i also feel the 18/6 sced causes less stress on mothers, better mother= better clones...
 
IMO, if you can keep temps and humidity in check then i would do 20-4 or 18-6. But for me, especially in the winter, my night temps get too cold and i also dont have a dehue so in full veg my humidity would spike to 80-90%. So running 24-0 keeps temps and humidity in check and made for a better gowing enviroment in my situation.

You need to spend the coins to get these things under control.
Growing properly is a total package. Not just at lights on.
What are you going to do when you need to bloom in the colder months?

Your comment to the 7 year old thread is moot! Your not giving point to the debate of 24/0 vs.18/6, as far as effect on plants in veg.

Your only exposing a gap in your grow area set up....

the sex of those plants is determined by chromosomes, deep within the seed genetics long before they crack open, NOT by available light schedules after they crack. cervantes made this error in his bible, since retracted it too.

Actually my bloom room has 2 quest dehues, heat, and works just fine lol and i took the dehue out of my veg after switching to 24-0 bc i didnt need it. Dont get your panties caught up in a bunch i was trying to add real world experience to this tread. My rooms are all dialed in and produce great. But in the winter i run 24-0 bc of cold nights. As far as effect on plants they eat a ton more in 24-0 but some strains ( like forum cookie or some of my chem crosses) dont like all that light.

As far as growing properly goes its proper. Would i like to do 18-6 and keep temps in check, sure, but i did what i had to do to make the best out of the situation i was in. Not every grower has unlimited funds to get all the bells and whistles for there grow. And by the way switching to 24-0 was one of the best decisions ive made for my plants in the winter.

Real world experience? To a 7 year old thread? Rooms dialed in? With no heat to the veg? Something is odd about this.....Seems to indicate a stand alone op, or a garage grow. No heat in the veg? That's not "dialed in".... Dehumidifiers - add heat...More odd...You start with pointing us to your name drop on Quest and you use 2.....What model? Why 2? I mean if you were that big an op. I would think you would have heated the Veg.......Lets see here, the model 205 removes 5.7 pints per kwh.....The 105 does 9 per kwh.....To require anything near those #'s you would need a pretty good sized op, and you say you have 2.....The price for those Quest's are, well, over priced.....Unless you commercial grow, and NO commercial operation would not have heat in the veg......Damn, back to the start of my point again - Something is odd about this.

Pantie's in a bunch?....Oh sorry, I forgot to give them back to your ole'lady.

You keep refering to a 7 year thread like theres something wrong with commenting on it. Ive learned plenty from old threads so whats your point. Quest 155 if you'd like to know and yes 2. They were 1900 a pop compared to the 205 which was like over 3k so i went with the 155's. Going from 4 shitty 90 pint home depot dehues, it was a great investment. But dont mind me im just a garage grower lol. For someone whos been around the block you sound like a troll looking to put your 2 cents on every comment. Your one of those growers whos stuck in there ways thats still growing 4-5 oz plants. And keep those panties my ole'lady doesnt wear any

I'm warming up to this guy quick like!
 
Anyone ever see their plants droop right before lights off? Wouldn't that be a sign that they do not require 24 hour light?

I think they said it somewhere near the beginning of the thread, or I read it somewhere else. The answer is - they get used to the lighting schedule basically. Once they learn the schedule, they start drooping a little bit before the lights go out to conserve energy. You might also notice them perking up when the lights go on too. To save some energy.

Yes, they perk up right before lights on too. After doing limited reading up on the term Daily Light Integral, I was curious to see if the plants droop before lights out due to the DLI threshold. I have noticed that some plants even same strain do not droop even when given weeks to adjust to light schedule. Or could this be some indication of the overall health of the plant whether it needs to save energy due to environmental issues.
 
my girls arent in a secluded tent and when the lights go out i dont need to be aware of the time i can smell them from across the house as they exhale in delight and get a few hours of rest.

its good for the equipment too to have some down time.
 
I have done both, each for over a decade. I am gonna stick with the 18/6. When I was a young grower I believed in the 24/0 but I have seen how the plants are tired after 16 hours or so. Plants do grow in the dark provided that the temps permit, they use sugars stored during the daytime photosynthesis.
 
Wow, did I really read 8 pages and ten years of opinions? Yeah, because I’m reading EVERYTHING I can possibly get my hands/eyes on. I put together growth chambers at the university in college and in some basements at the same time. What I just read was some awesome (and a few not so) opinions but not one comment on the facts that seem to really matter to deal with the question and Cannabis is driving me crazy for this reason.

first let me admit to being one of the most L7 you will ever meet. I’m asthmatic with severe respiratory allergies, so smoking is right out and I’ve never experimented with edibles because I live on prescriptions. Next let me assure you I am a degreed (with an actual education) horticulturist. I never thought I would see a day I could grow legal cannabis and that dream might die before I get it off the ground anyway, but I’ve got a plan, a business plan and a solid concept. I will see where it takes me. The best information on Marijuana is on the internet from guys growing small and many of them illegal gardens. 24/0 vs 18/6 is a valid argument on several fronts. First is power. Lights on 100% or 75%. I’m hoping for a 200 “mature plant” facility with 3x that vegging in the wings on rotation. I’m looking at a light bill USING leds in the six grand range at 24/0. Forty-five hundred per month instead is a factor. I think 24/0 makes sense IF you feed for 24/7, and IF you add CO2 for 24/7. Why is the amount, on a per plant basis, of nutrients used a mystery? Lots of hydroponic mixes available claiming to be the chit for MJ but after harvest, what is left in the tank? Answer, nm just start over. Wtf. For the grower of ten or fewer plants maybe. I’m hoping to have several thousands of gallons of fluid leftover between crops. So, if you feed for 24/0 (hydroponically) and you CO2 supplement 24/0, do you get the investment back from 25% more light? My 12/12 flowering will probably be backward. Light cycle at night. If the electricity makes any noticeable heat issues, they are easier to cancel when outside temps are lower. Same for an 18/6 option. You have to turn down the nutrients and turn off the CO2 for the dark cycle. Said dark period would be best in the early afternoon when temps are highest. Two plants, identical in every way, the one getting 25% more light also getting 25% more nutrients and both plant getting added CO2 during lights on. Has ANYONE done this? Next question, and should probably be in another thread, has anyone found a decent way to track nutrients in a hydroponics situation beyond TDS??
 
I've always vegged 24hr cycles because I don't need to blackout the room. The plants always seem fine going into flower. I really don't think it matters.
 
Heck, I've got three rounds of Autos, Durban Poison, White Widow, Northern Lights, to do this year so, I'm gonna try 20/4 straight thru with them and see what happens. My whole micro Scrog only uses 3 Kwhrs a day. Of' I eat the small change. :hump::bigjoint:
Sativa, Hybrid, Indica, sounds good and FUCK the Lights!:razz:

I do get a kick out'a these old Threads and how they talk about HPS and MH lights and how they tried to manipulate their specrum, poorly. Now you can select the spectrum and intensity to pretty much full sun+ some with simple LEDs

So nice this modern age.
