Use your imagation and keep your eyes ope and you will find more seed planting boxes! I don't plant in boxes I bought for planting I use what I find or get free. I keep my eyes open at a local garden center since they throw away tons of pots and containers. gallon round plastic tree containers and all types they throw away! Even the seed starters I must have gotten 50 of them free. Two years ago my friend who has a bread store had 20 2 by 2 plastic bread boxes that were 5 inches deep and 2 inch square holes all surround by a heavy plastic. These boxes are strong with handles n the sides. I use 4 of them last year and all I did is put them inside a clear palstic bag I got a t the brewery free. Any way they worked great for my tomatoes! I still have about 20 styrofoam boxes I will use this week! As long as the box is 5 or more inches deep I can keep the plants in longer! I will have 4 or 5 gardens this year at different locations!Looking forward to this year in my green house. What type of boxes are used by others here?
