I will be starting to germinate first tomato seeds today and over the period of the next two days. That's what moon planting calendar says, and even if it doesn't help, it will certainly doesn't hurt :)
My seeds are divided into a couple of categories. Firstly, by tomato bush and fruit size. So, I will start with micro-dwarf that usually can go outside early, since I grow them in containers on the terrace, then dwarfs, and finally indeterminate cherry varieties followed by the indeterminate large fruit ones. I will be planting them all outside in the same order.
Then, there are common seeds, that I have plenty of them, collected from my own tomatoes, those I will just mix and toss on a wet paper towel, place the towel in a try with lid and I will be checking them daily. Each seed that shows a root will be planted into a tray filled with potting mix.
Last, but not least, there are "precious" seeds that I have a few - from seed exchange with other growers for instance. Those will be placed in a small container (like pizza / hot sauce), separated by variety, 2-5 seeds each, nothing inside just seeds and moisture. They will be checked daily and sprinkled with water if needed. They mustn't dry out, it kills them, but they mustn't stay submerged in water as well.
I will place all trays and containers in the warmest room in the house, which is bathroom. If temperature goes below 24 degrees Celsius consistently, I might consider using either heat mat or just heat the room more. I will give the seeds up to 7 days to germinate, no more. Usually it takes 3 to 5 days from the start to the moment when gernminating seed with a tiny root is being planted.
