i am having great trouble with my vent system. the problem is that my ventilation system is not able to remove all the heat from the lamps. till yesterday i had only one hps bulb working and everything was ok. yesterday i transplanted my babyes to bigger pots and switched on the second hps and then started the troubles... my 2 vents are working at max speed constantly and the heat in the box is still over 28-29 degrees celsius.... any suggestions how to cool my box down because am realy worried about my girls and will they be able to live in such a heat.
