WHAT IS THE PERFECT GROW ROOM TEMP.

[mobay]

I HAVE BEEN READING DIFFERANT BOOKS AND I WANTED TO KNOW ABOUT THIS DAY AND AGE, NOT NO 1978 HOW TO GROW BOOKS. WHAT IS THEE PERFECT ROOM TEMPS?

[scobbie]

:stoned: i find 78 but then i learned from a old time grow book so this will be intresting:stoned:

[scobbie]

what you think of those cfl 200w 2700k lamps ,they look good dont they.

Mobay go take a quick peak in the FAQ's :D

There is not one real answer to your question. There are many variables to consider. If you are using enhanced CO² then you need higher temperatures then if you don't. Example: Running CO² you need temperatures around 88f up to even 94f to help the plant absorb the extra CO² and transpire.

With out CO² 78 works best until the last month of flower then you can kick it up to 82-85f so they transpire more and produce more resin by volume.

In a perfect environment the temperature changes with each cycle the plant enters and exits. It's all about controlling the environment.

I have not even talked about humidity.

Sorry but there is no real answer only a range to consider.

So then what's too hot?

[Zandor]

over 99f for longer then 30 min is to hot. Keep it under 92f for all times and you are safe. There are strains that can still turn hermie at that temperature so watch for those signs and have some reverse on hand just in case.

:stoned: so zandor if i am having problems with temp and my temp is 90 then instead of trying to get that temp down i could just get a co2 bottle and i would be ok as my dad has a pup and i have acsess to loads of co2 bottles are they ok to use,this would help me greatly as its cold were im from and the only way is to have a hot temp as there is other forces at work in the place were my grow room is,and if that is the case then please let me know
zandor or indeed anyone else whom is knowledgeble in this subject,thanks and sorry for hijacking your thread moby:stoned:

[mobay]

nice to meet you zandor, and thank you for the info. will be looking into a CO2 soon.

Go for it Scoob!

[scobbie]

thanks j dogg im on to it now ,yes ,yes yes

[Zandor]

yup

Here is a caculator to help you figure how long it needs to run every few hours to start. A controller is really the way to go it will save the gas and be better for the plant. But you can use a timmer and guess too, it's better then not having it.

excellent, thank you .
