That was the question when I prepared to start seeds indoors under lights, especially when it came to the nasturtiums. This packet came right out and said to do it... ...but this one didn't. (Funny how different seeds for the same plant can look so different.) I figured that soaking them can't hurt ....so I did. (Plus I have the wintersown ones that were not soaked to compare somewhat, though growing methods differ.)
There! These were set in a tray that went on the heat mat, so I'm hoping they'll germinate soon. (Still nothing from the wintersown seeds.)
I have two more varieties of nasturtium that I'll direct sow outdoors later, and I will soak them...
....but I decided to go ahead and try some of the 'Alaska Mix' and 'Spitfire' soaked seeds out right now in small pots.
Let's see what happens :)
