Maximum room temperature?
- Thread starter Goldwing
- Start date
What is the Maximum room temperature I can have before causing wilting and stopping growth?
What's the maximum time you can have those high temperatures?
There are so many factors that play on this....
air flow across canopy
CO2
Direct heat from hood...vs ambient heat...
strain of plant
ex:
my room has got as high as 94F...but I had a lot of air movement, with CO2...my plants didn't show any negative effects due to that..
What's the idea room temperature?
I would keep my room at 75-78F(lights on), and 68-70F(when off)...but that is what I prefer..
As I have heard a million times on here....listen to your plants

Still feeding
Stop feeding, start flushing with plain or RO water (more often than normal if its hot or you have wilting!), and 3 days before harvest stop watering (shortens dry time.) The last two days turn the lights off completely.

No way, I'm only at 53 days into flower
It's kinda hard to give "exact" answers - lotta variables
health, air flo, ya know,,, shit like medium can make a difference - so before ya get tweeky about "knee-jerk" answers, ya might wana be a little more descriptive - ohhhh and a picture might be good. --
You may have missed the notice,, most of us sent our crystal balls in for the 1000 sick plant check up.
That said - 80 is hot in my room and now that I have an AC for the grow - - I shoulda done this years ago.
I'm guessing you already have lights off during the afternoon etc,,

Yea knee jerky comments come every time without asking question first about those variables, hell when you use a cristal ball you have to ask question. even with your's in for repair ask away.

to answer question, temps are kept between 78-88*f, but have been high as 110*f.
lower 90's is ok as long as there is lots of air circulation, dehumidification, and minimal c02 enhancement.
beginning flush @ 53 days flower seems reasonable. have flushed for 3 weeks before. depends on how its done.
yep a total lie.
goldwing...do you want an answer to your question or you just want to knock everyone that tries to help? just so we can stop this dumb question that has been answered a million times before....
78 is the perfect temp, anything above 85 will slow growth. is that a knee jerker for you? you can get away with more but your plants will suffer.
oh and your at 53 days wow congrats...so how long does this strain go for in your PROFESSIONAL opinion that you dont need to flush now?
im sure the same love you give to ICMAG and its members will reflect on your im guessing MASSIVE PLANTS

The objective of this study was to determine the effect of light intensity, temperature and CO2 conditions on gas and water vapour exchange characteristics of C. sativa L. to establish suitable and efficient environmental conditions for its indoor cultivation.
WUE = water use efficiency
PPFD = photosynthetic photon flux densities
E = transpiration
Pn = rate of photosynthesis

still isnt possible...im no pro on CO2 but 4000ppms? isnt it supposed to be somewhere around 1800-2200ppms. and a foot of growth a day is not possible...what is that like 8 nodes or something. sorry but there are alot of knowledgable people on here that know that your statement is 100% false.
i would love to see what your plants look like at over 100* in an areo system.
