nutrients and water temp

[keith]

hi guys, does the temperature of the water effect how the plant takes up the nutrients, regards, keith.

[loylty gets u nothing]

yes

also temps above about 24 degrees lack oxygen

my res is set at 20-21 d celcius

all the best

bil

thanks heaps for the fast reply, cheers

Aparently the temp for optimum oxygen uptake is 24c

Im full noob but the fella that told me isnt

Maybe you could set you heater to 22c and add a floating thermometer so you can see if its right

Most everything I have read recommends 22 deg.

21C, is the knife edge, a little lower if ya unsure, better safe then sorry. The air temp and humidity will affect nutrient uptake more then the water temp.

 

Better to get a little slower growth and get full yeild, then get faster growth and reduced yeild, because of the temp of the water, over 21C and the chance of rootrot multiply heaps.

Ideal temps are 15°-24°C.

 

Water at 15°C holds a lot more oxygen, than that of 24°C.

 

At 29°C water holds bugger all oxygen, and roots in those temps can be damaged and are more likely to rot/wilt and opens up for fungus/bug problems the warmer it is.

 

It depends on what your other enviromental conditions are like to, ie: if its cold weather, run it a bit warmer to keep the plants comfortable, ifs it bloody hot, run it cooler.

 

I keep mine about 21°C.
