Hey all,

Should I have any concerns about keeping rain water stored over winter
for the orchids? I keep it in the same room and covered. No bad odors
but it does have a slight green tinge.

Thanks.

Mark



Mark-

I kept water in a 150 gallon tank in the basement over the winter for
years. As long as it isn't getting any light (solid container with lid,
nothing transparent/translucent) and was clean going in, it'll easily
last the winter. A little green from algae won't hurt. If it starts to
smell rotten, I wouldn't use it any more.

I have had a problem this year with the water turning black, stinky, and
oily now that it's kept in the GH. Still no light getting in, but I have
had to empty, scrub and bleach it twice now. Despite putting a little
physan in to keep it sterile. Go figure....
