Does it have an effect YES!... how much depends on the plant... strain etc... If i was growing outside i wouldnt be to worried about it. In doors i would do something to bring the temps down below 80f. unless iwas using CO2. Sure "he'll do fine" but why not maximize your potential if you have the ability to do so?!?

I do around 80 on and 70 with lights off, using 1 400w hps and 1 200w cfl, I plan to add a 3rd 600w hps but I know I'll need some cooling method by that point.... Fresh cooler air as others have said is great, but if you're in a hot climate you AC and vent your scrubbed hot air out of the room and have the AC and fans circulating your cool air. Bringing in air from outside when it's 100 degrees wouldn't do much better but if you live in a northern climate or cooler climate area than the cooler air would do wonders.

no 84 is not to hot.... if that is your light on temperature your fine...

just make sure your lights off temps are in the low 70s or you will grow hairs...not hard nugs

Just try to imatate mother nature in the fall.

In veg our mj plants can survive over 85*F... In arizona outdoors, flagstaff... we see upper 90s in veg

As long as you have good air circulation you should be fine. My temps get up to around 85 sometimes and i have no signs of heat stress and i dont run CO2.

84 is pushing it, but not a deal breaker. Try this --

A. Fan your plants to keep the air moving around them.
B. Adjust your watering schedule. When it got hot here I had been giving my girls 24 ounces of nute water in their daily watering.
When the temps spiked I added a 12 ounce watering in the mid-afternoon for a 50% increase in water.

Good luck, BigSteve.

My garden peak temp with light on is 86F & last grow got me 690g/sq m of killer weed (Exodus Cheese/Greenhouse). Use to have a peak temp of 95F that was causing elongated nodes + fluffy bud then i put my grow room on a reverse day night schedules & cut 9F. The best tool i have for cooling are 2 8" vortex for air intake & exhaust, I think I will replace them for 10" soon.

Ideal temps for flowering plants around 75F. That being said, I get very hot temps in the desert and my plants do fine in the heat, they just don't produce as well as they could.
