Tonight, I sat on my bed and planted some spring seeds in my windowsill greenhouse box. ($5 at Home Depot)
Yellow gooseberry tomatoes, pink brandywine tomatoes, mortgage lifter tomatoes, pickling cucumbers, okra, watermelon, orange habanero peppers, jalapenos, sunflowers.
This planter fits 24 seedlings, and does not require frequent watering. You just douse the little peat pellets in warm water, and they puff right up.
Then you plant seeds in them.
