High temperature Hydroponics

[surmi...@gmail.com]

What are the possibilities of Hydroponics at 28+_ 2degrees Celcius,
ie 80 plus minus five degrees Farnheit temperature . Has any body
tried this and if so what are the experiences?

I have tried that already.  My greenhouse sometimes even reach 30+ degrees celsius.  The plants grow well also.  But I have two exhaust fans and one circulating fan. I plant lettuce only.

Temps in excess of 80f are detrimental to most plants. The most
obvious sign is root rot.

Hi Subodh,
Adverse results frequently occur with the root temperature above 25 degree
Celsius (77 Fahrenheit), as the roots cannot take up enough oxygen.
In my earlier trials, I have also observed higher bacterial contamination.

I am not sure how well it would work except to say that in aquaponics
where water is pumped from fish tanks to water and feed the plants it
works well. In aquaponics there is no soil other than gravel and many
of the fish are kept at 80 f. The people that do this say that almost
everything grows at this temp. I am just setting up my greenhouse like
this so I dont have first hand knowledge.

proper suggested hydro temps are 68 to 72f.. with the min max of 65 and 75

below 65 ...plants start to hiberante.... above 75 root issues
commence... and above 80... root rot can almost always be guaranteed..
