A question for all you hydro guys.

Just curious, what do you all keep your res. temps. at?

Around 20 to 25 degrees works good for me

yeah 21 degrees cecius

i have read that about 21 22 degrees is optimum !!

65- 68 degrees

68 F is best, have has success all the way to 75 or so, much higher than that and you are risking a lot of diseases and issues.

usualy stays 67-69 F

in flower my temperatures were as low as 58 and it didnt hurt the plants so dont get bummed if it drops that low. Just check it every 24 hours.

p.s i was talking celcius not farenhiet thats how us brits do things lol

Which is odd, because our system of weights and measurements here in the US is called "Imperial" and is taken from.........the Brits!! Anyhow, I keep my reservoir at room temperature.

i've heard in the upper 60s F. mine is at a constant 68 degrees.

you there! You have enraged the wrath of my piggy war like ancestors!

The UK Weights and Measures Act of 1824, which not only modified the types and sizes of units, but renamed them from the English units of measurement to the Imperial System of Measurement.
This new standard was then introduced throughout the UK and its colonies at this time.

However, the USA had become independent prior to this and consequently had not adopted the Imperial system of measurement.
Instead, they had developed their own measurement standards, based on the English units system which was used throughout the States prior to independence.
