when is cold too cold?

Do you think 55-60 is too cold for flower?

Im not even sure why this is in question.. temperatures are not preference. Optimal temperatures are essential for proper growth and yield. The day someone tells me that temps are preference is the day I meet someone who hasnt grown enough to know the difference. No offense just spit balling from earth here.

Photosynthesis requires light, co2 and h20. But like I said, as temps rise, the plants use more co2(as long as there is co2 to use, obviously ) and more water.
In my opinion photosynthesis is directly related to temps.

The only reason you think that plants use more CO2 in higher temps is because the air is drier, causing more transpiration. If you keep humidity and circulation in check, temp doesn't matter. It's all about transpiration. Faster transpiration means faster photosynthesis and faster respiration, no master what temp.

It's not really up for debate. There's a reason it's called photosynthesis and not tempsynthesis.

Then go ahead and tell me why temp matters. Keeping in mind that I said, as long as it's within the range of above freezing and below 100 it's just preference.

Man great argument. So, does "photosynthesis " mean that the more pics you take of it, the faster it grows?
It isn't called "co2synthesis" either, but we all know co2 is part of it. It isn't called "watersynthesis" water must not have anything to do with it.
Sorry man, but there was no need for you to get crappy. Keep growing your plants in 40 degrees

It's not really an argument, at least I'm not trying to be argumentative. All the info is available everywhere in books and online.

If you want to be a smart ass, that's cool too. However, my plants are living proof that they can still thrive in cold temps.
 
Yeah and all the info says that you are incorrect and that higher temps do increase co2 uptake.
You were the smartass, "tempsynthesis"? I'd say that was a pretty sarcastic remark.
 
I'm just going to leave it at this...

I'm sure you are all great growers. I'm sure you follow regimens that were in place long before you've started growing and tailored them to your liking. That's fine. However, there is more to growing than just the "ideal" conditions that are regurgitated.

A cold environment is no different than a hot environment as long as all other factors are addressed BEFORE temp. That being said, I'm no master grower or expert botanist.

I was simply forced into growing in the cold and figured out how to do it instead of throwing money at it or battling it any further.

I'm not saying that growing in the cold is better. I'm not saying it's worse either. It's just another method that provides the same end results. Whatever temp you run, I guarantee better yields and healthier plants if you provide for the other factors before temp control.

Good luck and happy growing.

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

I'll wait.
 
I could sit here and explain to you what i personally know about ideal temps.. Ideal temps hold co2 better. Ideal temps allow your medium's PH to stay stable and not drop or spike. Ideal temps keep root zones healthy by encouraging proper growth. Theres tons of reasons why temps are directly related to the process of photosynthesis. Im not going to hunt down an article to prove this.. This is what I know from experience.

My experience says different. Does that make either of us wrong?

It abso - fuckin - lutely does matter!

You can NOT increase plant growth with the use of C02 supplementation with out higher temps and RH. If you don't run high enough LUX or U/mol of light. It won't be effective either. YOU, Rex could NOT get an increase with 55F temps and 70 RH like I've seen in your temp/RH gauge pics! It just does not work that way.
Your reading to much into what little you do read.

I'll bet any 75F run of mine against any 55F run of yours for yields any day Rex! I don't care if you have the VPD dialed in on 55F either!

Warmer is better! Having the proper VPD is important - like you said in an off kinda way.

Here is the formula for calculating photosynthesis rates. I don't see temp on there. Do you?

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 would definitely take that bet. Problem is, matching genetics for genetics. You find a way to do that and I'll run you straight up.

Light increases CO2 uptake as well as transpiration and respiration.

I'll be back in a little bit. Have to run out but I would love to have this conversation with you.
 
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?
 
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.
