Yes. That means about 1/2 to one teaspoon per quart of distilled water
(don't use tap water). It works on starting any pepper seeds, and gets
them to sprout about twice as fast. It is a germinating procedure from
the Federal Seed Act for breaking dormancy in pepper seeds.
Also, alternating the soil temp. from 80-85 deg. f. and then nights at
60-70 degrees F. helps also---it's good to get an accurate soil
thermometer to do that. I just got a call last week where a pepper
grower was using a chicken egg incubator to keep the daytime soil temps
in the 80 deg. range very nicely---bought it from his local feed store
for about $40 and is 2 ft. x 2 ft.
