Ideal temperature not achieved!

[Mista Sparkle]

Heat is my biggest enemy with my cabinet-in-a-closet system...

I have an air-cooled 400 watt light in a relatively small cabinet, and the cabinet is a bitch to keep cool. I'm trying different variations on ventilation with a 6" vortex fan and a 265cfm squirrel cage fan. I also have a thermostat and variable speed controller for the vortex fan. A window AC unit cools the ambient air in the room.

The idea is that the room is kept cool with the window AC unit. When the box warms up, the vortex fan kicks on, pulling cooler air from outside the closet and venting the warm air to the attic or outside.

I may use the squirrel fan to cool just the light. I'm also considering an attic fan to cool the attic...

I'll try to remember to post the details of my final setup.

I have a huge fukcin fan these days, but it still comes down to if you can access cool air or not for the intake.

[Tomthehippie]

Question about temperature:

Plants in Mexico and southern states grow in very high temperatures. So why is the recommended temp for indoor plants 72-76F ?

[Tomthehippie]

different strains do like dif temps! but i think it might be a general ideal temp. it is known that mg grows best at 25c

I'm pretty sure it's because maximum photosynthesis occurs between the temperatures of 75-80 degrees F, but don't quote me on that...

Keeping an exact constant temp of around 78 is almost impossible with temps dropping at night i have been trying to acheive this with inlet and exaust fans for years nearest i have got is 78 lights on 72 lights of but was having a chat with tom the hippie the other day and he recomended a site for lights and i came across this at a good price so ive ordered it so when its fitted i will post a report on it afficiency.be safe the postman.Hydroponics grow room control|Grow room heaters an
