Too be honest, I've never taken my nutes temp. I just watch the grow and look for problems. I do use airstones in each bucket. Cabinet temp is 84 w/CO2. My babies are looking great!

I've read that's the reason not to trim fan leaves. Fan leaves help keep the plant cool.

They also say to freeze bottles of water and add to bucket to cool temp. Too much work for me and what happens if water gets too cold. You'd have to experiment w/o your babies to check this out before just adding to res.

You can drive yourself nuts trying to get the "Best". So so many variables. I just concentrate on keeping my babies looking healthy & happy, and they're going to reward me nicely. Sure I could maybe get little more w/better equipment, but I'm happy with what I get.

Peace, PIF
