I have two sprouts that are about 4 inches above the soil. I am about 1 week after planting from seed. To support the stems of my new window plants, I am using a large paper clipped, reformed in the shape of a cowboy's lasso or a halo very losely around the stem of my plant. This seems to be a decent support, just make sure NOT to choke your plants. When I have the time, I am gonna try placing my plants in direct sunlight for about 1-3 hours per day to see if it makes a huge difference. Will let u know how it goes.
