if you are using a co2 tank set-up,you can have the lights and ventilation come on.
then after about 1/2 hour shut ventilation down, and add co2 for an hour.
then have ventilation for 1/2 hour, then an hour of co2 again.
repeat until the end of light time.
then leave ventilation on, till next light cycle.
this will only help if temps. stay below 86deg and humidity stays under 60%
If you get a vented shade like they show on your link, that would help huge.
