Hello! Hope everyone is doing well today... I need some help figuring out the starting process of sowing seeds/thinning/ transplants. A week ago my roomate and I planted all of our little seeds into cell packs (Each cell is about a penny in size), and by golly they have taken off!! Only problem is, we don't know when to thin them, or when to transplant them to bigger plants? All of the little lettuces have grows so much, but are tall thin little things.... are we growing them right? Here are some pictures to help! Thank you so much for your time!
