How far down in the soil did you place the seed?

how strong of a fan is blowing on them?

Even using a fan I find that they will tilt over and they need help sometimes standing back up

What I did was...

Tipped over the small pot as I hold the plant and dirt in one hand remove the plant from the pot. I very slowly removed about 2 inches of dirt from the bottom and placed the plant back in the pot. I then put the 2 inches of dirt back on top. This secures the stem better in the dirt and solves the tilting issues. Becareful of the roots and when you do remove the plant from the pot, make sure the soil stays together around the roots and plant so it causes only mild shock if any. My plants have not tipped over after that and do not seem to be in shock.
