Hi there, a couple of things to help:
I keep seedlings cand clones with just 24w of flu old T5.
If its a house common light bulb bring it to 2 or 3 cm from top of the plant, that Will work much better.
Other thing, start with the smallest pots possible, couse plant Will always stretch with this lights and for first week adding support is a must, then transplant them to slighter bigger pot and bury the plant up to first round leafs. This way they Will not bend or break with the heavier top!
Good luck!😉
