What size airpump for 35 gal

** Although I've had numerous successful harvests, I am new to growing hydroponically. I was going to purchase 5 3.5 dwc bubble boys from htg supply for 30$ *this Friday. But after researching it seems that I can make one better and bigger for a whole lot less.I would like to use good equipment for maximum results. I plan on using a 35 gallon rubber maid tote. What size air stone and pump would I need. Also how many plants would be recommended for the container? I was thinking 4 to 6 max. Any suggestions,recommendations, or anything else I need would b greatly appreciated, thanks guys!

tote work great BUT you have to find a good way to keep water cool. I grow in Coolers, like for drinks at the beach. it works great, light tight an keeps the water cool. I run at 60 an every 12 hours drop a frozen gallon bottle. Something to think about. colder water holds more o2.

cold water is good for the roots ???

cold water holds more oxygen. they love it if you slowly lower the temps I run 60-65ish . I have a friend who runs his res at 58F.

Too low reduces plant metabolism and nutrient/water uptake. Lowering temps later into flower helps with going purple quite a bit though. 68-70 is about ideal with a good system that has maximum DO to keep root metabolism rates up. The chemical processes happen faster at higher temps, though it is a balancing act with keeping DO high enough for roots and anaerobic bacteria defence.
