De Barao is one of the best lianoid varieties of medium late ripening (125-130 days). Fruits weighing 50-70g, have a very beautiful vegetable plant oval shape, never crack. They are excellent in fresh form and for salting. Yields are high and stable, transport white. Increased resistance to disease.
Soil Even though it's known as "potting soil", the best medium for seed starting has no soil at all. Use a sterile, soilless mix that's labeled for seed starting. Never use garden soil, which often drains poorly and may harbor disease organisms.
Warmth and Light Seeds germinate best at warm room temperature (70-75 degrees F); you can speed germination by providing bottom heat with a heat mat. Once they're up and growing, seedlings grow best in cool room temperature, about 65 degrees F.
Although you can start your tomatoes on a sunny windowsill, you'll get better results growing them under some type of LED grow light. Winter and early spring sunlight isn't nearly as intense as summer sunlight, and there are fewer hours of daylight. Insufficient light can lead to weak, spindly plants. A light garden with adjustable lights is ideal for seed starting.
Step-By-Step Seed Starting
Thoroughly moisten the seed-starting mix, and then fill the containers to within 1/2" of the top. Firm the mix but don't compact it. Place two or three seeds into each small container or each cell of a seed starter. Cover the seed with about 1/4" of soil and gently firm it over the seeds. Water to ensure good seed-to-mix contact. You can use a plant mister or just dribble a stream of water over the top. You don't need to soak the soil, just moisten the top layer. Place the pots in a warm spot or on top of a heat mat. At this point, the seeds don't need light. Keep the mix moist but not soaking wet. If your seed-starting system has a greenhouse top, use it to help hold moisture. Or, you can lay some plastic kitchen wrap over the tops of the pots. Check pots daily. As soon as you see sprouts, remove the covering and place the pots in a sunny window or under grow lights, keeping the lights just an inch or two above the tops of the plants.
