Bubble Bucket Start up Questions

Checking to see if a few other members have a similar situation. I want to start a bubble bucket system with 3 gallon buckets and an airpump for each. My issue is it is a larger closet grow with LEDs but this is in the southern USA where getting temps below 78-82 are going to be impossible. A res chiller per bucket isn't going to work and I don't want a central res. Can I sustain a dwc bubbler with temps of that range? Second, I want to keep them under 3 feet and run autoflowers so will a 3gal be a good fit? I was also pondering a medium rubbermaid system for 3 plants total per led panel. I am an experienced soil grower but want to move to a hydro system without water movement in and out of my containers. I want to use the advanced nutrients line if that helps answer the questions.

You could use 5 gallon coolers. Why so anti-reservoir? They make your life a lot easier.

Not when I want a set it and dump the res weekly. Also these aren't clones so they will all need there own nutrients tweaked so I don't have 3 burnt plants and 3 good ones. Also it is an apt grow so any ability to accidentally dump 50+ gallons on a catastrophic failure is possible and is not something I can accept risk wise.

You could do 5 gallon coolers for now and if you want to switch to using a reservoir down the road you could easily do so with a few modifications. That would help a bit with temps.

I'm looking to put 3 plants under each led panel so 5gal just will not work. Someone please chime in with help to my current design and if it is practical at the temps and conditions listed. I'm not going to completely redesign a system like that. I have most of what I would need on hand already.

Good luck!

I maintain my temps between 74 to 84 and I use 29% H2O2 at 3ml per gallon every other day and my plantts are rockin. The heat is killer this year
