I have seen blogs about vertical gardening or small space gardening, the use of pallet is the best and unique idea in my opinion. Pallets are inexpensive some bloggers suggested that you can ask them from Lowe's or Home Depot since they discard them anyways. I got mine from my husbands' work for free.
You'll need the following to make this vertical garden.
Pallets or pallet - free
Pots - i bought these plastic pots from Lowe's for .98 cents each. (about $8)
Bungee cords - bought them at the dollar store for $1/bag (5 bags, about $6)
1 bag of garden soil - i bought Miracle Gro brand ($3.88)
Plants - $2 /6 small cells ( about $4)
I spent around $25 for this project. Not bad at all ;)
My herbs- basil, from the stalks that i saved when i made tomato basil soup, micro greens, parsley, thyme and another basil. I have yet to add more herbs.
