Started seeds too eary.
This is my first post but I have been lurking at the Hosta forum.
My question is about impatiens that I started on Jan.27 they will be a month old tomorrow. They are growing great are about 4 inches tall and are bushing out.I have them in a window with 1 T8 light on them.I have been running the lights 16 hours a day.
I am a bit concerned at the rapid growth rate and wonder if they will make it to Spring.I am in Sweden and our Spring can come quite late.Might not be able to plant them until the middle of May.
If I have the lights on for less hours will that slow them down without making them weak?
Is it possible to just keep them indoors until suitable planting time if I of course re pot them?
I have searched and not found any answers to these questions except I found out that planting too early is a beginners most common mistake.It said on the net that it can take 2 to 3 weeks for germination.Mine came up in about 5 days.Boy was I surprised.
