it's a little early to start...

i will pinch and bruise and crush my stems on my girls to help them build stronger stems.

keep the babies under the fans, the action of moving wiill help strengthen the stems too.

when they are about 8-10" tall is when I start the pinching and bruising. you might even feel the stem snap or crush. this is fine.

I'm amazed how much abuse these plants will take!
