hi !!! what temp should a dwc reservoir be?? i hear its supposed to be cooler at night and arround 70f at light!! anyone know if this is acurate??
65F or so up to 75F give or take a little bit
The plant starts to die at around 90F.
The colder the nutrient solution, the less up take by the roots
same thing when it gets to warm, theres less up take by the roots.
(the plant slows down). I think you could go down as low as 50F
I think thats about the point where you start to kill it.
Cutting should be 75F to 85F. Same thing around 90F you start to
kill the cutting, but a higher water temp say 85F makes your cutting root faster.
What this guy says and if you are using DWC it's real important.I would not let it get over 70F... 72 was when i got root rot... (in DWC system) you can get some additives that are supposed to prevent other biological growth and root rot, but 65-70 is ideal.
also, the closer to 65 you can keep it the more oxygen it holds...
ebb/flow systems are not so sensitive to res temp - you could go up to 75, but i wouldnt cross that.
