I love growing herbs and tomatoes in my house all winter, I have two Aerogardens (spendy to get set up but relatively easy to hack to save money going forward).
Since I follow indoor gardening a picture came through my feed of taking a boot tray, putting water in it and then putting in the cut ends of onions, lettuce etc to easily grow green onions and some lettuce at home. I am going to give this a try, because I think it is fun as much as anything else...and I use tons of green onions.
I was planning to set up a simple microgreens garden at home this spring - Get a big translucent plastic bin, make the lid your base, put a bag of potting soil on it and cut in slits in the soil bag. Sow your seeds in the slits and use the translucent bin as your greenhouse. Since we are still well into winter where i live in Canada I don't think I will be able to do this this year (assuming everything is shut down by the time it is warm enough), but those of you who are living in appropriate climates right now, I would totally be doing this. Simple, easy enough to do on a balcony and you can start harvesting in a short time.
