I found a neat little hack for starting seedlings, let's talk about it.
Planter trays are great. You start your seeds indoors, they sprout, you transfer them. Then you tuck your planter trays away into storage. If you have storage. But why buy, use, and store planter trays when you can use the rinds of citrus fruit after you've eaten the fruit? There is no answer to that. Planter trays are now obsolete. Boom.
Poke a hole or two in the bottom for drainage, fill with soil, add two seeds and some water. When it comes time to move your seedling outdoors, plant the whole damn thing. The peel will compost in the soil.
