to hot to hot

my cabinet is 3 ft w 4 ft h 2 ft d pre built.two flors mounted one on each side flors veging to slow switch to 600w hps mounted on top temp went to 35c.cabinet does have a fan and exhaust.what should i do

How you going to ask a question that is in 3 sentences that arent clear and provide no where near enough information for anyone to provide a halfway intelligent answer?

No air cooled hoods, intake size, exhaust fan cfm, type of fan, carbon filter, ambient temps, using CO2, running fluros same time as HPS or just for veg?



At any measure i think an air cooled hood/cooltube is a must in this case. I run a 600 hps in a 2 x 3 x6 cabinet and keep my temps to 91 if I exhauset the cooltube with 300 cfm. If I use a 100 cfm in my cooltube and exhauset my cab at 80-100 cfm my temps stay 3 defrees above ambient.

ok i wasnt clear.it is a air cooled hood,not sure the size of intake fan but squirrel cage blower is 265 cfm,scrubber carbon filter,no co2 was running flors and hps trying to veg,not sure what ambient means so cant tell you what temp is.flors one is 1200 lums 6500k other 1025 lums 4500k 20ws

ambient temperature refers to the temperature of the room that your grow box is in

ok thank you.can you answer the thread above.room temp is around 82f

And your cab temp is 89 correct... You are doing well as you are only 7 above ambient in that small area with that 600. Afraid you may have to drop ambient my friend or maybe pull cold air into the light tube, or cab intake.

Also make sure you are blowing you light exhauset out the room.

thank you for your reply metal.so i should but a fan in the room,well that help get the cooler air for the in closed grow cabinet?the 600w hps has its own fan built in.not sure how to blow exhauset out of room the cabinet was all prebuilt
