Okay most of my plants just grew 2 1/2 inches in two days is that normal? I'm sorry if it sunds stupid but this is my first time growing and just thought that was pretty fast.... well thanks.
What kind of lights are you using? If your using floro's and they arn't within 2" of the plants then they may be stretching. If you can post a pic then it will be easy tell.
Your plants are super stretched, how far away are your lights? You need to put them closer to your plants' canopies so they don't continue stretching. When you repot them make sure that you bury those stems. Good luck.
As Pewpil said, they grew so fast because they are trying to reach the light. It's called stretching, not desirable. Repot them (only one to a pot) and bury most of that stretched stem. Get the light closer.
So by "sunlght" do you mean that you are growing them outside? If so are you leaving them outside all of the time are they growing like on a window seal or what.
