Not a first time gardener but first time trying to succesfully start seeds indoors. Wondering if this is what they are supposed to look like after one week after sowing? Beginning furthest away: Marglobe Tomato, Beefsteak Tomato, Brocolii, Cauliflower, Bell Pepper and Lettuce. Are they supposed to be that long and spindly looking? I went ahead and have removed the cover since everything is up with the exception of my Marglobe and Bell Pepper. What next?
