I was considering Growit, which my local hydro store used when I purchased a 4 inch starter plant. The only drawback I can envision is if the area got tilled, there would be clay shards in the soil. I don't know how much of a concern it would be with such a small amount of clay material. Any sage advice?
Also, I don't want to spend the month of January washing it and have no idea if it would stuff up the drain.
