peace :p

well im not as experienced as some of the other people here on the website are but ill try to help. ive heard that maximum oxygenation occurs in water about 59 degrees or so but i doubt its good practice to feed MJ plants water that cold. but as far as the temperature for the plant goes id say no lower than 70F if you still want to maintain a healthy grow rate. could they grow in a lower temp atmosphere, probally but it would likely stun growth if it didnt kill it altogether.

:rasta: Well I think at 59F and there dead.70F to 75F I do believe is what you want.
Mel Thomas has this to say{To optimze the uptake of the nutrient formulation you have chosen,gently heat the solution with an aquarium heater to around 75F }.I have read other books that said the same thing.
To cold or to hot they stop growing.Between 65F to 75F is good for the plants.They can grow in hotter temps. but they must have water or they die.:rasta:

I think low 40s wont cause damage but sure as hell will stunt growth. Best temp is around 65...any colder than that you will see slowed growth. 75 is too warm...it will work but problems may occur.
