Re: Red Hygro
An observation for what it's worth:
I have some red hygro growing under two Vitalite and one Ultra Tri-lux bulbs.
A single stem has branched in four directions about 5 inches below the
surface of the water. The two branches that are directly under the Tri-lux
bulb are compact and quite red. The branch that is in between a Vitalite and
the Tri-lux is somewhat red and longer. The fourth branch is under a
Vita-lite bulb and is considerably longer and mostly olive-green with just a
bit of red at the edges.
