What are the best types of tomatoes for the Pacific Northwest climate?
In Growing Vegetables West of the Cascades (Steve Solomon, 2000, pp.241,242), the author notes that any tomato advertised in a seed catalog as needing more than 72 days for maturity will not likely reach a ripe old (tasty) age in our region. Solomon suggests purchasing seed only from regional companies like Territorial Seed Co. or West Coast Seeds. The varieties he recommends are
1. some that ripen early in the Willamette Valley (bred by Jim Baggett) = Oregon 11, Oregon Spring, Santiam, and Gold Nugget
2. slicers = Fantastic Hybrid, Pic Red, Early Cascade, and Kootenai
3. cherry = most are prolific here, but Solomon prefer's Jim Baggett's Gold Nugget
Here is a link to an article by Chris Smith in the Seattle Post-Intelligencer (01-19-2006) that introduces some new tomatoes and other vegetables for 2006.
Seattle Tilth has an article by Kirsten DeLara (2011) called "Grow Great Tomatoes in Seattle" which includes a list of the author's favorite varieties for our area. Also check Seattle Tilth's annual list of tomatoes available at their sales, and their reports on tomato tasting results.
Mother Earth News published an article on the best Pacific Northwest varieties in February/March 2010.

I started some seedlings of tomato, pepper, snapdragon and lettuce in my sunroom under shop lights in peat pots. The temperature in the room is in the 60s at night and 70-80 in the day. I keep the soil evenly moist, but after 3 weeks, none of the seedlings that have germinated have true leaves. No secondary leaves of any kind. I cannot imagine why this would be under those conditions. Can you help me?
There are a number of variables that may be at work here. Are the seeds new? If not, were they stored properly? Also, seeds have varying lifespans. Some seeds require light to germinate and others do not. Some must be sown on or near the surface, and others must be sown more deeply. Seeds require varying degrees of heat. Oxygen is another requirement: is the seed-sowing mixture in your pots compacted? That might prevent germination. The steady moisture you are providing is good, and the temperature in the room is about right for most seeds.
University of New Hampshire Extension has useful general guidelines for starting seeds indoors.
The temperature of the water or the time of day in which the watering takes place may be influencing the growth of the plants. According to an Ed Hume's Garden Questions Archives article entitled, Starting Vegetable Seeds Indoors, seedlings should be watered with water that is just a little warmer than room temperature. If the water being used is too cold or if watering occurs in the evening as the temperature of the room drops, this could be slowing the plant growth.
I am wondering if the day time temperatures are too high. To quote from The Seed Starter's Handbook by Nancy Bubel (Rodale Press, 1988): "Plants grown indoors in warm rooms put on weak, spindly, sappy growth that is difficult to manage. Start seeds warm and grow seedlings cool."
Lastly, Starting from Seed by Karan Davis Cutler (Brooklyn Botanic Garden, 1998) says: "Since both heat and light fuel plant growth, the relationship between the two is critical. A common mistake among home gardeners is to keep plants at too high a temperature for the amount of light they receive. What often happens is that the gardener tries to compensate for slow growth with more fertilizer and higher temperatures. The result is limp, leggy seedlings that are hard put to cope with outdoor conditions. On cloudy days, the experienced gardener lowers the temperature to compensate for the lower light levels. While every plant has a temperature range it likes best, within that range, the cooler you keep the temperature, the better off the plant will be. Do not take things too far, though. A combination of low temperature, low light and overwatering is ideal for the development of damping-off fungus."

Garden Tool: Whether you planted your tomatoes in April or mid-June, by mid-summer it's time to think about training and staking strategies. An eight-inch tomato may be dwarfed by a "tomato cage" in June, but by September the cage is usually swallowed up and listing dangerously to one side. The alternative, tying up one central branch to a stake, improves disease resistance, but requires constant vigilance to pinch out all suckers. University of the Virgin Islands provides an excellent illustrated explanation on training tomatoes.
