what is an acceptable temp range for nutrient solution?

Hi all,

I've just set up a flower room for a bucket DWC grow, 5 buckets in total, all connected to a reservoir for easy maintenance. I bought several aquarium heaters, but they're too long to fit into my 3.5 gallon buckets:roll:, so I'm wondering if I can get by without heating the nutrient solution in the buckets (the reservoir will be heated, at least). I have air temps around 80 degrees and am 'testing' the system now without any plants for a day or two. Not sure what the water temp will eventually level out to, but right now it's around 57 degrees, seems a little cool, but it is slowly coming up, I think. I believe I've read that 65 is a good temp, but want to check to see what the acceptable range is. What is too hot, and what is too cold?:confused: Any help is appreciated.

It has more to do with oxygen levels. Above 72F water does not hold enough oxygen to support healthy plants, between 55-70F is the best range for water to be in. I personally maintain my water temps at 60F even when air temps are at 80+F. You will have to experiment a little bit as each strain has its own particular needs and some plants my not need as much oxygen as others.

60-65 is a good temp for the water anything lower then 60 I wouldn't go. Personally I would heat the nutrient solution. If the pad it to big just exchange it for a smaller one look at the lizard heaters with a thermostat their small and range in sizes!

According to leading growers, including a couple universities that study Hydroponics 58 F is the desired temp for maximum oxygen retention. Your milage may vary with prevailing barometric pressures yadda yadda. Essentially everyone here is right.
