Blow under the bulb? I have a 400w /600w digital just went up to 600w bulb and don't want to go back even though it has been nothing but heat issues sinceWhat size ballast you have?
Is that fan blowing directly on the bulb? If so try not blowing over the bulb that might help bring the temps down
Gonna need to get the air cooled hood then especially with summer coming up.... For now I'm using passive would my tent stay cooler with 1 or 2 or all 3 passive vents open? Well at least I upgraded the fan because the hoods I have been looking in to have all been 6in and upBasically you need either a intake fan to blow cold air in, or an air cooled hood
Haha humidity is at 22% not even close.... Tried using a humidifier but it was a joke... Ended up ditching it... I have a thermostat tied to my light that's were I have been getting my highest temps.... Another thermometer usually reads 77-79 at top of tent.... Which leads to another question I've asked on a different forum.... What's better a 400w a foot away or a 600w 18-24in away.... Seems the higher I put my lights the more I think about popping my 400w hps bulb back inUmm couple things.
I would tie the thermostat to one of the strings on your reflector and make sure the thermostat is at CANOPY LEVEL to see what temps your plants are.
It looks like if you raise the light your temps should be fine. 79-84 is fine aslong as your humidity is 75-85%
Hey thanks for the advice... My budgets a little tight right now for an air cooled hood so I'll try getting rid of the reducer and see if that helps....oh didn't see the reducer that must go or just put ur 4'' fan back cus its a waste
there is a reason its a 6'' 4 is just constricting
