Poted underwater plants?
My LFS has potted underwater plants...what is the purpose of this stuff in the pot? A fish store near my work, has plants in pots but they all waste away and thewy give me the pots with all the stuff in them for free...could I use this stuff as some sort of fert??? please let me know
The stuff in the pot is rockwool. It's not really useful for anything in the tank. It's used for hydroponics, for the roots to grow into. I assume some potted plants are grown emersed hydroponically. I still don't get why jave fern and anubias come potted, I've bought them before and the rhizomes were completely rotten.
