HELP! All my WH have been choked to death by algae collecting on the
roots. The lettuce is still alive but not looking too good. The only
part of the VF not affected is the watercress. I was washing the roots
every day(what a pain) but forgot for three days.= rotten WH straight
to compost.
My water is clear .... some algae on sides ..... lots on
roots?????????
What can I do other than wash the roots every day? This is a new one
on me.

Hmm...I have not seen this before. What is your flow rate? Maybe the water
is sitting too long?
