The seeds are planted so just wait for the sun and heat

Spring is here, and it's time to get seeds in the soil. It's getting warmer and brighter days, so now is the time to start the project. I have no record of how many plants I can grow on the wall here, but I can expand to other walls if necessary. There are different germination times on the different seeds, and I'm not quite sure how long the different seeds spend, but they certainly don't germinate at the same time
