Tips on helping my seedlings.....

Ive been growing these for 20 days now. I have been placing them outside during the day in the sun and then move them into my basement at night. Im getting a little worried at the stems right now, so someone please help me.

Those are stretching bad. They should be getting 18 hours of light. When you take them back into the basement what kind of light do you have for them? Do you have a fan on them? Go to FAQ and read getting started.

I once covered part of the stem with more soil.so it supports the stem. and gave it a litte water. so the stem grew, and roots grew on the part of the stem which I covered with soil.....you have to be careful not to let the stem rot though...I just add a little water at first..for root development

but I think those stems are very fragile..they would rot. you just add light and put a support...

You have to figure out why they are stretching and mix that problem.

watch out it could be ph ...lol...no really itsa light problem need more light...
