Dry-stall vs Horticultural pumice ... was algae and moss in seedling pots

Hi Roland and All,

As a matter of fact, I had the same experience with seedlings as Ken did.
Just recently I got some seeds (nerine x amaryllis & amaryllis x brunsvigia)
via the BX that were donated by Ken. Since I had never grown these
particular interspecifics from seed, I wasn't sure how to go about it. I
sent a query to the group and Ken was nice enough to give me his formula for
starting these seeds.

Very shortly after they sprouted (100% by the way) I noticed some algae
starting to form on the growing media. I thought to myself, what do I have
in my arsenal to combat this? Right away I thought Physan 20 should help,
and it did. I water my plants with rainwater only, which is rather acidic in
the Northeast and since algae and mosses love acidic conditions, the only
conclusion was to make the water less acidic by adding the Physan 20. The
seedlings are growing nicely and starting their second leaf stage, but I do
keep and eye on the algae and as a preventative I give them a soak once a
month with the Physan.

Warm Regards,
