Hi people...

What temp should the nutrients/water be in NFT? And does it really matter? I know u can shock them by giving v.cold water but if they got used to it would it be ok?

thought about gettin a little heater to put by the tank to heat water(prob only a bit) and the room (2 birds 1 stone and all that). Or do i really need to get a fish tank heater?

Slightly off the topic but does anyone work in extreme temps? eg.. 30 top and 1 bottom?

Apart from keeping the roots at an optimal temperature for growth and nutrient uptake, your temperature can have a fairly dramatic effect on your ph and cf.

Liquids can hold more dissolved solids at higher temperatures, and so if your nutrient temperature is all over the place, you can find your cf and ph readings going all over the place as well. When you have your nutes help at a constant temp (mine are at 21 degrees C), then you find that your cf and ph are a lot more stable, and you are able to get a better feel for what you need to add to adjust them over time.

The downside is that warmer liquids hold less oxygen, so the addition of an airstone or oxyplus (but not when using Superbud) reoxygenates the nutrients.

A normal fishtank heater will cost you about 15 quid. If you are growing on a cold floor like in a garage, then putting some polystyrene sheets under your tank will help it keep its temperature a hell of a lot better, as its insulated from the cold floor.

sweet thanks for the advice... using hydrotops bioponic and ur not supposed to use oxy-plus with it cos it kills all the microbes or somethin?? Air stone will do though hopefully.

Thanks again...

( Imeant fluctuating room temp really, 30 day and 1 night)

You can pop down to your local reptile/pet shop and buy heater mats really cheap. Handy if your tank is on concrete or something similar.

That's a handy little tip Rudders....thx

yeah man.. there about £40 quid..

You'll have to get a fish tank heater rather than a mat as if your temps are between 1-30C you will not get a result.

You should get a metal rather than glass one for obvious safety reasons.

seen as the thread is 5 years old i am sure Pez got something sorted

ha ha

... i never realized that either
