My seedlings are far too Spindly..

[murihikukid]

Hi...I wonder what the secret is to growing strong seedlings with a thick stem ...after visiting a local gardening centre and seeing the young plants and how strong they looked I must be doing something wrong....My seeds go in a Parasene self watering (by capillary cloth) propagator and once i see the first set of true leaves I transplant into a bigger container....I am using a Peat moss base with Perlite mixed with a seed raising mix and a teaspoon of lime ...I am using CFL lights and this may be the problem...

Any help would be appreciated..Thanks Ron
