San marzano hard to germinate?
I sowed 9 different kinds of seeds into seed starter on Friday night. 5 different kinds of tomatoes, variety of lettuce, and oregano. It is now the 5th day and all of them have sprouted EXCEPT the San marzano. The rest of the tomatoes are almost 2 inches tall.
Roma's and yellow brandywine came out first. Then red brandywine (although only 1 out of the 2 I planted), lastly cherry.
Do San marzanos typically take longer to germinate than other seeds? Or are they just harder to germinate, period.
The seed tray spent the first couple nights on my wireless router for warmth. As soon as first seeds popped out I moved them under grow lights where they are getting approximately 14 hours of artificial light a day. They're also somewhat close to a west facing window. I still have them over a heating pad which I turn on once in a while for 2 hours at a time.
Help please! Of course all the other seeds should sprout when the San marzanos are the only ones I'm most interested in...
