Introducting Royal Flush by
Humboldt Nutrients
Royal Flush by Humboldt Nutrients
is a premium flushing solution that
helps drop unwanted salt buildup.
Royal Flush will correct issues
with over-fertilizing, balancing
the grow medium. Royal Flush
can be used by indoor and
outdoor home gardeners for
all varieties of plants, including
flowers, vegetables, herbs, trees,
berries, shrubs, ornamentals,
annuals and perennials. Royal
Flush supercharges the flushing
process, binding together undesirable salts and heavy minerals.
Royal Flush then strips these
larger particles out of your plant,
leaving behind the sugars, strong
flavors and aromas. For more
information, visit your local indoor
gardening store.
