whats with the clover in ya pots ?
Clover is a way of fixing the nitrogen source in my medium. The roots are always dying off and the worms in turn feed on them as well. Sorry, I have been away for a while.
I also plant celosia in there too just for shits. The clover also helps out the living environment by keeping moister above the soil for a little longer. I have lots of beneficial bugs in there. When the grow is finished, I'll let the medium dry out and they chill out till the next one starts.
However this is the official answer you may be seeking.
Clover and symbiotic rhizobia bacteria found in root nodules can fix large amounts of N from the air (Figure 1). This reduces or eliminates the need for N fertilizer in fields having good
clover stands. However, the rhizobia bacteria only fix enough N for it and the
clover plant host.
