I'm in the finalization stages of my grow room. All that's left is the final choice on light and cooling.
While I understand grow lights will cause heat, I have yet to find how much heat (ranges) can be expected from certain types of lights at given distances and room size effects.
Currently the room I'm in stays at 79 degrees using central AC in the lovely Nevada desert. Obviously I can drop the temps (ambient) at a cost.
I'm building my own grow room within this spare room. It will probably end up being about 5' x 5', within a 10' x 10' bedroom. Basically just framed in poly/mylar unless I step up for a tent, but that's not in my current plan for my first DWC grow of 8-10 fem seeds from Nirvana.
The current plan is 600w MH light. Adding cfl's at needed locations as the need arises.
So now I need to figure out how much real cooling I need. Will I need a in-line exhaust fan (and obviously venting it out of the room)? If so, how big is really needed? Is some of this hype? Will 2-3 strategically placed room fans do the job?
Let's face it, you can spend $50 - $300+ on an inline fan before adding the requisite ducting, filter, hangers, etc. What if a $75 unit could do the job but being the newbie you are the store sells you a $200 unit claiming that's what we need?
I have yet to see one, but a possibly cool idea for all forums users is a thread creating such information. Things needed to create a rough guide for users could be (add to the list if you think of anything):
1. Room size.
2. Light size/type (wattage, MH, HPS, LED etc)
3. Avg distance from plants - light on temp - lights off temp @ distance
4. Avg room temp - light on temp - light off temp
5. Inline exhaust CFM
6. Fan on temps as above
7. Fan off temps as above
8. Room floor or desk type fan info and results of use.
With enough people adding in their own personal grow room information as above we could come up with realistic information, compiled in easy to read formats.
In the meantime, how much cooling do I need? !!!!!!!
