is 77 not hot enough to use co2

hey i was wondering if 77 is good temp for co2 enrichment. i know thats a good temp for when not using co2.also i now 80-90 is ok with co2 but wondering if everything is cool or got to get it hotter

i saw someone else post an article that said 84 degrees is where peak uptake happens but there still absorbing some at 77. so your not gettin the most bang for your buck but it will stillo help. im not sure though i dont use co2 yet. im sure that guy will find this though lol he'll give a fur sure answer

thanks man
