I have my pothos planted in clay pots foamed to the viv walls. But there is no drainage. they are withering, yellowing and leaves are falling off.
The other vivs with the same pothos are in plastic pots foamed to the walls with holes drilled for drainage and are doing well.

Where have you all gotten your abg? I'm not sure if there are generic knock offs or brands to avoid.

Thanks for your opinions! I'm going to have to check this stuff out!
