Okay, my tomato seedlings are going gang-busters and I'm afraid I'm going to get spindly plants.

How do you harden off the seedlings and get nice stocky plants?

I put them outside in the sun for 60 min. today - they are only about 2 days above ground.

I'm going to put a fan on them most of the day.

They are only having sunlight by a window - no light bulbs. But I'm going to cover some cardboard with foil and put that behind them.

I'm also brushing them with my hand a few times a day. (Sounds harsh, but I read it on at least 6 websites, so I figured it was alright.)

Anything other tips? I'm in the Danger Zone now - I figure if I can get healthy seedlings to the garden, I'm home free.
