Hi Antonio,
welcome to 420 mag.

If your vents are close to where your extraction is your just recycling the warm air back into your grow space,
You need to supply fresh, cooler air to bring the temps down,
All tents usually have vents at the bottom, open one of these and close the top ones, the air from lower down will be cooler than the air from up high (as heat rises) and will help with the cooling.
Hope this helps.

ok gotcha thanks, have the temp now around 28c with a hole at the bottom of the tent open....thanks for your advice...;p

Those Timers are only rated for 600 watts. An 8000 BTU A/C uses 1200 watts while running & about 3000 watts for a second or two at start up. Could easily melt the Timer & start a FIRE.

Bud thank you! I now its dangerous. I will buy a bigger one and I will make it manually temporarily .
