1)the air temp is measured in the column that says: high/low, h/l, or 60°/49°

So I take it that the air temp is ranging from 66 to 43 degrees at the moment.

2) I'm watering every 3 hours for 16 hours during the day, then I water twice every 4 hours during the night.

Watering every 3 hours, but for how long is the pump pumping at a time (5 min, 30 min, 60 min etc.). I am asking because I'm wondering if the roots are being suffocated. Also with only one watering in 3 hours (unless it's a long one) they might not be getting enough water. Both situations could be a problem? It looks like you are watering more at night. With once for 3 hours during day, and twice in 4 hours at night (in other words, once every 2 hours at night). That would be odd, especially when the plants don't really need it at night.

P.S. Are you using an air pump and stone in the nutrient reservoir?

3) the water cycle floods way above the roots of the veg.plants that I started in my aerogarden. I later buried the root base at the bottom 2 inches of hydroton in the buckets, thinking I could bury them like I do my "earth" tomato plants.

Not sure how deep the buckets are. I wanted to know where the water level in the buckets was in relation to the top of the growing medium. I was wondering if stem rot was setting in. Tomatoes are very susceptible to root and stem diseases and fungus, especially when small like that.

4) It's been very humid and rainy and windy. Yesterday it rained 2.64 inches in 24 hours and the wind was blowing 40 MPH. I have plastic wrap around the plants to protect them from the wind.

5)I don' t know what it means do the plants wet?

Well that is what I meant. If the leaves and stems are wet all the time, fungus could set in and be quite damaging to small tomato plants like that. Humid conditions aid in fungus because the leaves and stems don't get a chance to really dry, so they remain wet continuously.

8) the variety is Cherokee Purple Heirloom Mater'

I have no idea if that variety is a cool weather variety or not. Going by your chart and the maximum daytime high is 66 degrees, unless this is a cool weather variety it might not be suited for your cold conditions. You could either get a cool weather variety (if that isn't) or build a greenhouse for it, and heat the greenhouse.
