Fans and temperature requirements

Hi all just a quick one, I'm just about to build my room and was wondering is having a fan blowing about the plants and maintaining the temperature as crucial during veg time?

The reason I ask is that space is kind of at a premium and I need to know whether I should factor some extra space into the veg room for maybe a heater/air con unit and a blowing fan.

Any help much appreciated

i would say that going with a air cont. and blower would be great!... but it is always crucial to keep your plants at premium...

you wouldn't like sleeping comfortably then wake up to bake to death...lol

An oscillating fan will move the air enough to provide constant fresh air to the leaves, and move the stems around to strengthen them. That makes your plant stronger, and better able to hold up the massive weight of huge buds.

yeah, I neglected to put a good oscillating fan in the area with my flowering plants. when the buds got big, baby started splaying her stalks open like a hooker on Friday night.
