We are moving soon and I am going to take my plants out of their pots and move them in a bucket. Right now there are dirt and rocks in the pots and I have been thinking what substrate to use because I want to try something new. I was thinking safe t sorb but it seems like more work. My husband got a bag of plain clay cat litter, so I think I will experiment with washing a small amount and seeing what happens for the next few weeks with just cat litter and water in a cup. Has anyone used cat litter for substrate? I was reading some really positive things, but also people going right to putting in their tank and turned into a cloud/mud disaster.
