Some plants slower than others?

matermaniac · March 9, 2010

This is my first time growing from seed. For the most part, everything has germinated. Some, now almost a month old, still haven't started their true leaves. Seeds were either purchased from Trade Winds Fruit or from tomatoes I bought at Farmers Markets.

So, should some varieties still not have begun to grow their leaves? Everything is under a grow light for about 18hrs of light a day.
Oh, I did give everything a drink of weak fish emulsion just the other day.

Here's my list.

You could try presoaking for 24 hours a few seeds of those
that have not sprouted at all, then put them inside a moist
paper towel inside a plastic sandwich bag. I leave the bag
closed for the first 24 hours, then open it, and set it in a warm
place (beside a furnace register if you have central heating
works for me). I also wet the paper towel with a solution of
1 part hydrogen peroxide (typical drugstore stuff) to 10 parts
water (prevents fungi from growing on or around seeds that
have to stay wet for a long time to sprout).

I have had seeds of a couple of varieties take 6 weeks
to sprout. I doubt if it is genetic, more a matter of
environmental factors like how old they are, how dry
their storage environment was, etc.
