Here’s an inexpensive cure for you. If you place unwashed dog hair around your plants, the scent will keeps those critters away. We have recommended this to several folk and they all said it did the trick. If you don’t have a dog, you can often get some clippings from a dog groomer – but be sure the fur wasn’t washed first as this would mask the smell that repels. For rabbits and deers, your easiest bet is to elevate your GrowBox above where they can reach.
