Default thermometer

it will work, but it will not address the problem of adjusting the temp of the water. I have a water heater (fish tank) that heats the water to 70. In the summer I have a water chiller to start cooling the water when it reaches 74, and it has a built in thermometer in the unit that is displayed.

Default right

Any Fish Tank section (even Walmart) would have good drop in thermometers for 3-10$. Finewood, I was interested in temperature control as well and had a spare 1/3 HP Chiller laying around lol. My problem is I have multiple reserviors so I built a heat exchange out of thin-walled plastic irrigation line forming coils and running through each chamber via bulkheads. The jury's still out...

FYI: I would suspect going as far as adding chillers is a less common but preferable thing.

Default chillers

Or you connect all the reservoirs using large diameter hoses and in the last one you pump the water to the chiller that deposits the water in the first reservoir.

I keep my reservoirs at different ppm's. I'll post my set up on here soon.

Bigdaddy, I don't know what you mean with the humidity. I'm beginning too, but as far as I know everybody starts their seeds in some sort of contained plastic tray- with a clear top to let in light (a lot of plants need light to trigger germination)

I even started some Cilantro recently in a zip lock bag in rockwool cubes. Anything that holds in the humidity creates a fog type deal- tuppawear, taco bell salad bowl container, etc. Also I started all mine indoors where it's warm (70's).

There isn't a specific type of thermometer used for hydroponics. Digital thermometer can get expensive, though $10 isn't bad at all for a digital one. Though just like with anything electronic it may eventually give false readings. I personally just use a small standard glass fish tank thermometer I got at wal-mart for $1.97. I just tie string around the suction cup and toss it in the reservoir for a couple minutes to check temp.

16% humidity?? Wow, that's extremely low. My weather station won't even register anything below 20%. Like daytonajim00 mentioned most people start seeds in some kind of seed tray with a clear plastic cover. The plastic cover holds in the humidity. As the water evaporates inside, it creates humidity, and the lid holds it in. So regardless of what the outside humidity is, inside the tray stays around 80% to 90% humidity. But you can use just about any covered container. As long as the top lets the light in. Though you should open it up once in a while so the plants can get fresh oxygen from time to time.

Thanks For The Reply I Scoot Down To Pet Store Grab Glass Thermometer
This Way I Will Have 2 Ways To Check Reservoir Temps

As For Humidity I Know It Has To Be 70 to 80% in seed Tray One I Have Has Vents Also I Put And PC Fan On One Side and keep other side slightly open ...

but yeah house humidity was 16% .. I Know For Plants It Need To Be 40% to 60% .. my thing is which would be better a cool mist or warm mist humidifier to help keep humidity between 40 & 50% ?

What's the normal air temp in the room? If the air temp is on the high side, than cool. If the air temp is on the low side, than warm. However I'm not sure that they make humidifiers that put out cool mist because cool water (humidity) condenses quickly (dryer air output). 40% to 50% humidity is much better than 16%, but 70% to 80% is much closer to optimum greenhouse conditions.

I have been thinking about it, and I could be wrong, but something doesn't make scene to me. I think either your humidity senor is off, or your not reading it correctly. Because Like I said 16% is extremely low. I live in the desert and our humidity is higher than that during this time of year. You said you were in Cleveland Ohio, so I checked the weather there, and it says currently you were at 86%. Now there will be differences between inside and outside humidity levels, but nothing even close to a 70% difference. Not withough't running Dehumidifiers constantly...

It's normal to have outside humidity in the 80's or 90's when it's raining, even afterword. Typical for your area I would expect around 50-60% humidity normally on a nice day. 20% difference between inside and outside would probably be normal. But beyond 30% difference I would say something in your home is acting as a dehumidifier, HVAC system etc. or your humidity sensor/s are off. Especially when you say when you got up today your humidity was 16%. That's just too much of a difference to make scene naturally. There is no way your humidity should be that low in your area. That level is equivalent to the desert (where I live) during the hot dry July and August months. Even at 30% indoors now, that's about a 50-60% difference between inside and outside. Why is there such a drastic difference??

What do the same meters say the outside humidity is?

I Have No Outside Temp/Humidity Gauge...

All I know is this right now outside is
Humidity: 70% Pressure: 30.41 in Dew Point: 3 F
Temp 14

I'm confused on two points. First you said you Have No Outside Temp/Humidity Gauge, but you also state a Humidity of 70%. How do you come to that conclusion? Second, again you said you Have No Outside Temp/Humidity Gauge, but why cant you place the ones that are inside, outside for a while?
