I have been dumping my coffee grounds outside since January. DH kept complaining that when I would throw the filter and wet contents in my burn barrel, that they would never dry out. Now, the filter only goes in the burn barrel (which is a lightweight plastic trash can on wheels and located by the back door by the kitchen,) and the filters dry out nicely. I have a small pile of grounds. Not sure what I will do with them, but I can certainly mulch plants in the Spring. I have 5 very fine lettuces that I started from seed. They are all about 7 inches tall. I moved a heat mat out to the porch, where I keep a slightly leaky fish tank. They were transplanted last month to a 16 inchish, 4inch wide rectaingular plastic porch planted (that has seen Better days), so I moved them to the fish tank on the south ledge of the unheated porch, with a glass top. It was cold last night, but they still look very good. I have started genovese basil (2/30 seedlings survived, in big pots on a heat mat on top of the fridge), opal basil (transplanted 13 from a pot bc they didn't like the kitchen sill, now repotted and on top of a heat mat on the top of the fridge), one pot of opal basil with about 20 some seedlings, 2-3 inches tall. THEY seem pretty happy on a ledge next to the window in the kitchen, BUT they are right underneath the coffee maker, and getting enough heat. I have been growing leeks in leftover containers, and they are about ready to transplant into individual cells and put them under lights in the basement, where it's chilly.
I promise to take pictures soon and start a 2020 Duck's Thread!
