Quick Question

[Mick420]

What should be the Temp. of the water in your hydro water?
If I can get a quick response that would be very appreciated.

Sry about that but you get what im saying!

If you post in the right forum you'll get an answer.

I thought the question was in the appropiate section ... hydroponics. I will help u. The temps should be b/w 65 degress and 72. Anything over 72 and u run the risk of root rot.

Yes, I shoot for 70-75, but if your room temp is that, than you probably won't need a heater or chiller.

The warmer, the faster growth, but more chance of root rot.
The colder, the slower they will grow.

The propensity of water to hold 02 in solution decreases with increase in temperature.

Metabolic processes occur at a higher rate @ warmer temps.

Yer lookin' for a compromise between divergant growth factors- the best ratio of temp/02sat that you can achieve.

In the practical world, that usually works out to a desired rootzone temp of about 65-75, but you can go higher if you can get the O2sat level up- I've been as high as 13mg/l @ desired root zone temp of 83F, and growth rates were just stupid-well beyond what could be expected a rTemp 70F.

Please do not take that as meaning " Bleed in extra tank oxygen use a water heater and yer plants will get huge". This was an evolved strategy intended to max out a weird ( truely, unimaginably weird) system.

I'm just saying this isn't cut and dried, and there's room to play in here...

But 70F is a good # to shoot for, knowing that you'll need to really think about aeration if you get too much higher...

Well this is the light I was talking about but I went back to Wal-fart and in it's place got a grow light.

Good choice. Halogen not good for growing plants.

And actually what I've found to work much better than walmart grow lights are replacement fluorecsent bulbs. The ones that say they equall 200 watts, but only take up 40. If you can't find those, 100 watters work well too. Those regular grow lights seem to make the plants hibernate at best, unless you get a shitload of them.
