Temps too high?

I can't get below 91 with humidity about 40%. I have no real exhaust fan, just a clip on fan blowing air out. I have a 6'' intake fan blowing air in, and an oscillating fan. Outside temps about 77. I can't see just being around 90 degrees being a deal breaker thoughts?
 
I just went through this and my crop suffered because of it. 85 degrees is the optimum high in my opinion. You have to get the temp down. Below 80 degrees is best.
 
Agree with kingfish. Anything over 85 for an extended period of time is not good for the plant and can cause it to hermie of deform the resin glands late in flower. 85 is tops for veg but 80 is tops for flower. You need an exhaust fan to pull out the hot air and get it away from your plants environment. No need for intake fan if you have a tent and a good exhaust fan setup. Negative pressure is more than enough to get air to the plants and in my opinion works better than having an intake fan. Oscillating fan is good for airflow but not adequate to get rid of the heat produced by lights.
