So what your basically saying is that If you grew 2 cutting from the same plant in different temps.. One being just above freezing and the other being a constant 75F that the end yield would be identical?.. Like I said I dont think you have grown enough to with out a doubt say that temps are not directly effecting how your plants grow or uptake water. You can do math formulas and read articles all day. But until you have definitive proof through your own experience, you dont really know.
I'm saying if the conditions are right for both plants, which would need different environments, then yes.

This isn't coming from an article or whatever. That chart was just a quick reference as to how scientific data shows that temperature does not affect growth in photosynthesis.

That's theoretical science that I'm applying to my grow with, what appears to me, as no difference from temp to temp.

Temp, at least in my garden, definitely slows down growth, the colder you go.

Common sense dictates, man made these maps for a reason.

I'm just assumin your inside garden is replicatin a natural outside garden with optimal conditions, like me.
I push for higher transpiration rates than nature can provide outside in the cold.

When a plants transpiration rate is increased, so is it's respiration and photosynthesis rates. Can we all agree on that?

If we can, I'll move on.

Rex.
Your so fulla shit and it ain't all yours!

You ought to sit on your typing fingers and let others answer questions.........Your only burying yourself in your BS!

I mean I would care less if you gave quality answers.....But you don't!

As far as temps go.....EVERY book will put you at a range of 70-75F .

ANY FUCKIN BODY that has written a book says to use a 70's area temp range!

Now why the hell do YOU think you've re-invented the wheel?
I don't think I've reinvented a wheel or done anything that hasn't been done before. I do this every year because I have to. I learned from doing research and applying theories. It was a success for me.

It's been a reliable method that allows me to not have to run a heater, get my lights closer, and grow my own bud.

I'm not saying that it increases yield or that I don't make mistakes. I'm not saying it makes the plant any better in any way (it seems more hardy in my OPINION). However, telling me it doesn't work because whatever does not cancel out PHYSICAL LIVING HEALTHY PLANTS.

Here's my theory on why most of you think warmer temps really matter based on your experience.

How do you get bigger yields? Average answer is more light, right? Everybody hears or sees this all the time. What increases heat? Lights.

Therefore you're adding more light which gives off more heat. You don't want to run a fortune to lower your temps to 55 right? Why would you? Hell, a room at 70 is much more comfortable to walk into than one in the 50s, right?

So, have any of you ran the same setup you run but purposely dropped the temp down to 50-55? Didn't think so. It would be asinine to do that. 70 is much easier to control with a lot less electricity. I don't have a choice. I do it because I have to.

Show me a scientific article that specifically states that temperature alone is responsible for CO2 intake.

I'll wait.
I never said that temperature "alone" is responsible for co2 intake. It sounds like you're going back on your previous statement and admitting that higher temps do increase co2 uptake (which was my original statement that you took out of context ).

Not admitting anything I haven't already said. A warmer air is a drier air, correct? A colder air is a moister air, correct?

That's why temps seem to make such an impact on you guys. It creates drier air which increases transpiration. All I'm saying is that you can max transpiration in cold to the same level you can in warm with the right humidity, watering, lighting, and circulation conditions. There's no difference in growth between 50 to 80 degrees in MY OPINION and EXPERIENCE.

Yes there is and why did it go from 33 degrees to now 50 degrees? Try enriching a room with 1500 ppm of co2 at 50, it probably wouldn't have much of an effect at all.
I don't even like when my smart pots get below 65 really, but 50 (or as you were saying a few hours ago 33 degrees )? No way, I'd buy a heater asap.

I had a small4x3 room that was outside the house in the summer I ducted cool air from a crawl space under the house in the cold months I used a small electric heater with a built in adjustable thermostat that would cut in & out I had a thermometer on the wall to eyeball my real temp I also had it on a timer so it only came on when the light was off also in the cold months I unplugged the air cooled hood to use the lights heat to warm the little room 62-82 degrees was my goal I didn't have no scientific proof summer time I would set my timer to run light at night in an effort to keep overall temps manageable & in the process of putting together another little room but have the same goals for my temps when things get outside that range I take steps to correct it

I didn't drop my temperatures purposely but the setup was exactly the same; I had an 'open air' grow space in my garage where the temperatures were regulated by the temperature outside. During spring, summer, and into fall I had great results with yields just under 1 gpw. During winter however, my results were very poor because of the cold temperatures (see post #27).

You're going to have to show more than some dinky little seedling to prove you know better than science because right now you sound like a typical RIU-Ass-Clown spewing bullshit.

Ok, 33 then. Personally, I try not to let it get that low in case it drops that 1 degree. A 5 degree buffer is more acceptable for me, but whatever.

I'm not saying you have to. I'm not saying you should. I'm simply saying you can. Neither one of us is going to change out minds so you'll just have to watch my grow in disbelief if you want to see it work. That's the only proof I can give you.

And I don't know what you're saying warmer air is drier air? You'll have to clarify more, but... warmer air should have more moisture as it is able to hold more water. So 50 RH at 50 degrees has LESS water vapor in the air than 50 RH at 80 degrees.
Exactly what I'm saying. That's why you run a slightly higher humidity in 50 or 33. It doesn't have to hold more moisture but it CAN.

Ok? That's not even comparable to indoor growing styles. It's all about ideal, right?

I just used outdoors as an example that the plants can survive in cold temps.

Cold temps are not optimum no obviously not as it's been said above everybody knows the optimum temp range for cannabis, but necessary no! This is the point Rex is attempting to make, other factors are more important, I myself spent a lot of time trying to raise temps worrying so much about optimum range but still never getting close, my tent runs between around 16c and 22c lights off and on, i managed to raise temps lights on and off but the drop when lights off we're much more drastic and this affected my plants more than the Low temps, therefor I now try harder to keep optimum humidity and airflow, my plants do fine, I wouldn't advice growing in cold temps if u can avoid it but the point to be made is it's not the end of the world

Another additional tidbit just for science's sake. Colder air is denser and contains more oxygen and CO2. There's less reason to flood your tent with CO2. Doesn't make it better or anything, just a thought.

When someone says "there is no difference in growth between 50 and 80 degrees" (and then said 33 to 80 degrees ), it definitely seems that they are trying to say that cold temps are optimal. But if not, then I'm arguing for no reason. Of course I know that a plant will survive in cooler temps, although 33 I think may be pushing it.

His point is he sees no difference in growth from cold to optimum BECAUSE he so rightly pays more attention to other factors like humidity air circulation, mainly respiration
Arguing should not come into it, debate there are lessons to be learnt no matter If u agree or not

Pre warning if your going to argue with Rex over this make sure you have your facts and plenty of knowledge and experience behind you because Rex defiantly has stacks of all three on this subject alone
Not sticking up for no one I'm just saying
