Fully Controlled Greenhouse.
Sowing Method: Transplanting Germinants.
Seeds are sown in flats containing Sunshine Mix #4 Aggregate Plus (peat moss, perlite, major and minor nutrients, gypsum, and dolomitic lime).
Seeds are mixed with media to sow and are surface sown.
Flats are watered in with an automatic irrigation system and placed on a heated bench.
Seeds are sown on May 1st.
% Germination:60%
This species germinates very well; careful not to oversow flats. Disadvantage to direct seeding is that weed seeds are often mixed in with sandmat seeds.
