i call this Gardener's Tea:
1 cup Epsom salt in bathwater, some green clay. steep yourself for at least one hour.
Epsom salt is an excellent source of magnesium and sulfur, which is great for your skin, and it makes your plants lush and green as well. I used a flexible bucket to carry the water to my plants after I was done. Use a light weight pitcher or other container to fill it up halfway. Otherwise its heavy!
