growing sunflowers indoors help!

[QueenFee]

I am not a very good gardener but my daughter was given a sunflower seed growing kit and wanted to grow them. i assumed if they were kept indoors this would not be a problem so we planted etc and have now put them into a big pot. However they have now sort of flopped down - is this normal? and does anyone know how long they take to flower?
many thanks all
don't want a brokenheated DD just because her mom kills plants just by looking at them!

sorry to say I have never been able to grow sunflowers indoors. unless they are the special dwarf variety that can be grown in pots they need too big a pot to be successful inside. sunflowers were originally from semi arid areas and so put down large fragile root systems and the floppiness is either not enough water or not enough earth to support their weight (the roots spread out to take account of the tallness of the plant but in pots cannot do so).
use a big a pot as you can then, tie in with a bamboo pole or similar and water well but making sure the earth is drying out before watering again but never let it dry completely and hope for the best!!
forgot, they also need lots of light, at this time of year they are usually dried out on the stems and the seed head is drying and ripening, as the sun sets much earlier now, you might need to add in artificial light too when.

thanks that helps!
I think I may have over watered them in my concern. Will let them breathe a little and put in a stake. They are in a very large pot so that should be ok.
They are on my kitchen window sill and the light is on in there a lot - should that be enough?
