temp bottom line

ok. i know the temp should be 75-85 tops but my box stays at like 87-88. i heard you should never go over 85 but is that 2-3 degree difference really going to be a problem? is their anyone with some experience that can drop some knowledge on me? thanks for aqny help

if your plants look happy then it`s ok. it depends on the strain. every plant is different.
if the plant is to hot leaves may droop and start to canoe, edges will burn. slow growth
