about 2 weeks old

am new to growin and i just grew some bagseeds i have no idea wat strain they are. i was wondering how long it takes 4 the stems to bcome like hard because right now they r about 2 weeks old and they are about 7 inch tall that a few cant even support themselves... i need to put a straw next to them so they dont bend over.

They are stretching because the light is either insufficient or too far away. Go to FAQ and click on getting started. You need to do some reading.

not enough light they are sretching. more light and a little fan blowing on them will strengthen the stems

i use a 150 watt light how far should i place it from the plants?

is there anyway i can save it now? =[, can i plant them deeper?

i left for the weekend one time and my plants stretched 3 inches. i got a fan next to them and brought the light really close and they are doing great now just read up a little on stretching
