cybersix said:Hi, me again with my supid questions
These are the first four seedlings, they are outside in a cold frame.

The temps are around -1°C at night and 2 by day.
They were planted in pots in october.
I still have 4 seeds of one of the cross that didn't germinate yet, but if everything will be fine by the end of january they will be planted as well.
The growth is poor and slow, the sun doesn't hit the garden until spring.
So I thought of bring them inside again, placing them in the garage under the house (about 15°C there) and use grow lights like these

They aren't expensive and they use very few W/h so having them on for some hours per day should not cost much.
I wanted to speed up growth.
It's something you would do? Is it a stupid and useless idea?
Many thanks!

Your questions are definitely not stupid, they're good questions. I honestly can't help too much yet because I've still to complete my own foray into growing plants indoors under lights. I did wonder, though....I think I read online that the red/blue lights are used to promote flowering, which makes me wonder if doing that in the winter impacts their flowering habits when they are later placed outdoors. I wonder if its better to use white light and if that promotes more foliage growth which might help the plant strengthen and gain nutrients before it flowers. This is all coming from a new-to-indoor-growing person, so it's all speculation on my part.

...Is there anyone else who might know the answer or have a more educated guess?
