After germination, when the seedlings get to about 3-4 inches tall, I spray the stems with water, lightly sprinkle with rooting hormone, and then bury them almost to the lowest set of leaves. (leave some room for watering) When done, plant is approx 3/4" tall, out of the soil, ready for any breeze your fan can throw at it. By the time the plant reaches 4 inches tall again, stem is much stronger and needs no support.

I use this simple technique every grow, with every seedling. Has never failed.

I don't have to stake my plants, unless it's to train a branch, or start a clone.
