Well this was an interesting read. LMAO! I'm gonna go with what many master growers and book writers say, 75 degrees SIR YES SIR!!!!!

Listen to 2ANONYMOUS. You all really should keep lights off temp above 60-65 degrees. A space heater that kicks on when lights go out will do the job. Just because your plants "look" ok doesnt mean they are. Look into it.....about metabolism and root zone temperatures and what not. Make sure when using a small heater that your extension cords and timer or thermostat can handle it. A warm cord is not good. I been in countless grow rooms where the ext cord and timer were hot and at the point of causing bad shit to happen. Be careful and dont let room temps dip much below 65 for a happy garden with happy plants....thats a fact.

How insignificant temps really are huh? Wow. Whatever works for you bro. Dialing in the temperature and keeping it consistent is EVERYTHING in my growroom.

You know i always kept rooms 76 -80 degrees , lights on and 68 - 70 lights off.
With great grows ,, after a couple years i started playing with lights on temps ,, and actually found 82 - 87 degrees and saw overall grow increase in all aspects..
Rex being you been on here pretty much one year you must have at least two grows under your belt ??? would love to see a plant grown in them temps other then them seedlings ...
I mean show us a 3 - 4 -5 week vegged plant seed or clone, Cause i know for certain it will not be same size or vigor , as one grown in right temps ??
This is going to be my last post in this thread cause really its just plain stupid ,,
Rex look at the seasons from Spring to summer to autumn , and temps
Rule number 1 any person that wants to be successful, should look at how mother nature does it ,
Really that is what most growers try try to mimic as best as possible , with that said as fruit set begin in all fruit bearing species and yes Marijuana falls in this category.. So from seed to harvest what happens in nature ????
As temps increase seedlings germinate in spring as days get warmer plant strarts to flourish Veg State ,, when autumn comes do to light hr decrease this triggers plant to start making SEEDS cause really thats what all plants want to do is create off spring including MJ ..
So light hrs , influence fruit set , and as it comes closer to harvest temps also drop day and night which further pushes the plant to finish ...
So putting this all into perspective How do we do this indoor ?? Well not to many people will start seedlings with 1000 watt HPS lol
they start off with T5's CFLS or low power once plant germinates and true sets of leafs are out then people tend to put them under more power etc etc etc
least that is how i always do it as i head into flower i tend to flip 12 /12 up to 5th week
Maintaining 55- 60 RH where like mother nature day n night temps and light hrs are lowering daily i change lighting to 11 on 13 off and drop overall temps down about 8 degrees as well as RH by 5 degree increments so by
Week 6
10 hrs on 14 off and again room temps down lights off as well as lights on but still in plant operating range
so by the time i am on last week prior to chop i will have RH down 40 - 45
light hrs 9 on 15 off and room temps lights off 55 - 60 lights on 68 - 73
just like mother nature and it also saves me on power and trust me i get the best out of the plant

Where have you learned this from?

Dj himself...who i consider one the the true breeders out there...even mentioned this temp differential playing a big factor in phenotypic variation. Theres not many good breeders....most are seed makers....understandable if you wanna jump in and make a quick buck. But it takes years and thousands of plants and selection and diligent note taking. Most seed "companies" hit everything they get with one male they "think" is good and give tester seeds to growers all over the world for a report. Hardly in house. Hardly true plant breeding for true hybrids. It works obviously but its a compromise. Helps sales greatly with colorful websites, ads in trade magazines, t shirt and hat apperal. This is all hype to boost sales....to stay in the public eye with a product that basically you or i can do in the confines of our own grworooms. Ive chucked pollen all around ....many times. Ive gotten no better or worse results than those 100$+ packs of seeds with fancy packaging. This is primarily how i create new stuff. Ive found that over time...with my simple seed making that stuff i grow out eventually adapts to my rooms and methods. And its pretty awesome. Most arent willing to wait that long. Or have the space. Look what most are getting with a seed pack purchase these days.....a lottery ticket....a scratch off at best. Very difficult with the time, money, and legality out there to have huge greenhouse facilities and outdoor acreage for the sole purpose of creating true breeding stablized cultivars. Sorry this is off topic...i get on a rant that is barely understandable and iam baked out of my gord on some blue petrol from sin city. Basically another one of many but ive been extremely lucky with SCS. This petrol is amazing smoke. Unique in my gardens for now.

This is 65 at lights out. Didn't do it on purpose.

I'm having this same problem right now I have my plants in my basement and I'm in nj so it's like 10 degrees outside I'm trying everything to keep it above 70 down there but at night the temp drops to about 55 so I'm hoping it doesn't hurt my yield .. Good luck man.

Well i guess parents,, growing up on a farm, and Family owned botanic Garden one tends to learn all aspects at a young age..

Not sure if your talking to me ,, that grow was a make quick make shit grow room made clones for someone but they never picked them up so made a buddy a deal , and he let me set it up at his place, and yes dead of winter, and had a space heater in there but problem was it was the type with that spring load on bottom of it safety Feature in case of tip i guess ..
Anways it shut off a few times during grow and i was hardly there so yeah they got cold

Here's 2 mothers from a breeding experiment at a little over 4 weeks.
Planted in pots outside on November 22nd and brought in on December 23rd for cloning. Temps were around mid to high 50s sometimes 60s during the day and sometimes as low as the low 40s at night. Somehow... They survived.
I dunno why you guys are giving me such a rash of shit. Do you really think I would be defending this as steadfast as I am if it didn't work? Do you think I enjoy the ridicule?
You can say what you want. You can hate the fact that you can grow plants in cold weather. Doesn't really matter because they DO!
Now I've tried to be polite and I've tried to explain. Every time I try, you guys throw science in my face like I don't know wtf you're talking about.
If I didn't know what you were talking about, if I didn't understand how the plant grows, if I didn't understand the relationship the plant shares with it's environment... How in the fuck could I grow in it?
Can you grow in 40 degree weather reliably? Can you get good results in "below optimum" temps? I do, plain and simple.
Now I've resisted the shit talking until now. I don't have any pics. I just got this phone in December. That's the only pics I've got. I try to post them every day in the thread that I linked in this thread.
You guys can either continue to shit talk for no reason at all, or you can watch the damn plants grow and form your own opinion on the subject.

Spot on when lights out I don't let my room get under 65 prefect

That was basic memory and figured to be off a cpl one direction or another. Heat of the moment = REX.
Yeah I hear you @2ANONYMOUS ! I do a run with near 90 canopy with a controlled temp mid plant at 75 giving me a cooler root zone of around 68. (props to Riddle for this method)
Yeah I manage Pheno expression and coloring by temps and the coloring even farther by the supplementing of K too. This makes temps even more effective and deeper coloration is achieved......These are Ghost cut OG plants with the Sativa side expressed by higher daytime's and coloring by lower night temps/larger temp swings lights out.
By having higher canopy temps you still get the color shift at the canopy level, even in the summer months. K supplementation becomes more of "requirement" during the summer also.
temps
with K supplementedI use a stand alone organic K called "strengthen"......Forget the brand as I got several cases from a defunked hydro store as they closed.....Higher K by 3 points from after the Solo cups and dbl that 4 - 6 weeks into bloom - strain dependent!
Grew up on a farm eh? Me too. Retired from regular job to come back to the farm and begun an organic one. Some of the neighbors liked what I was doing and picked up the ball. I now manage a 3 farm organic co-op and we are having a great time. In the process of converting another (dairy this time) to organic and we will then cover the bases on organic products! The trick was finding a compatible packaging facility for the dairy operation. We contacted a another (the only other) organic dairy op in the expanded area of operation. They surprised us with being happy to meet us and willing to package for us as their operation was in real need of expanding due to demand and they had no increased supply = BINGO! We sell directly to them! They pic up directly!
That op should be OMARI / FED / STATE certified in March.

Whether you CAN do it is not the point !!
The point is you shouldn't for OPTIMUM results!
If you THINK you get GREAT results from 40 -50 deg temp runs - Your inner moron is slipping out again!
BTW. The defs in the plant in the pics - are most likely directly related to your "cold temp" grow style! Your getting late season outdoor nute restriction in the uptake = FROM the colder running temps!

The very minor N def in the pic is because they were hungry from not being fed. They used up the mix and I didn't give them any teas or toppings... But by all means, carry on with your ignorance.
