Temperature

i am sorry i know there must be lots of topics about it but i dont know why i couldnt find any although i tried to find in search section. and i dont really want to goog these kinds of MJ things because of its risks may seen by others.

so my question is how much heat do my plants need to grow ideally if all the other conditions are fine ?

In veg 70-80 is good, much over 80 can be a problem. In flower cooler is better and at lights off down into the 60s is fine.

1 celcius = 33,8 fahrenheit
so 70 F. is ~21 C., 80 F is ~27 C.

i always thought cannabis plants need around 30 celcius which equals to 85 F.

85 degrees is mostly considered maximum without CO2, on an average pot plant. However, if you get a strain native to hotter regions, you can supposedly get it up to the high 90 degrees without issue. Some of those PC case grows have to get hot, but people are doing it.

so i must keep the heat between 21- 27c.

With lights on yes. And check it at different points in the grow room, you will be surprised at the differences. Some will see 82 down at the bottom of the plants and think it is ok when further up it is over 90.
