temps too high at 92 farenheit (33)

hi guys my temps have been as high as 92 even though i am using 2 cooltubes the thing is my plants are thriving and look very healthy do i have any cause for concern, i switched onto 12/12, 2 weeks ago and already my plants have doubled in size and a couple have got bud sites developing, one of my blueberry plants even grew 6 inches in 3 days

if it doesnt seem to be causing any problems, why worry?? 92 really isnt that bad as long as there is ample airflow and water...

you could change the position of the thermometer maybe its under the lamps.i think the best is at the height of the plants ,next to the lamp not under.well i put it under the lamp just to see and temp is 34 sometimes but next to the lamp is 29-30.you could move the lamp higher if its not to far.somebody hear posted that having good air circ/vent you can grow even in 100f.depends on the strain too.
