Seed (Sexual) Propagation
Concept: Selecting soilless media, sowing seeds, and managing their growth are important of the health
and schedule of marketable plants.
Objectives:
1. Select inserts for 1020 trays.
2. Fill inserts with media correctly for sowing.
3. Demonstrate 3 methods of sowing seeds.
4. Fill out pot sticks (labels) with required information.
5. Demonstrate proper irrigation techniques for new plants.
Introduction:
Seeds area means of rapidly increasing the numbers of a certain plant. It is quick and economical
method of starting plants. The care in this first stage of plant growth will lead to success in the
production of crops.

Media
Dirt = Stuff under your finger nails.
Soil = Sand, Silt, and/or Clay.
Soilless media = Medium in which plant are
grown without soil. May include sphagnum peat
moss, vermiculite, perlite, coir (coconut),
manure, bark, etc.
At our greenhouse we use Pro Mix #1 by
Sungro. It includes the following ingredients
and percentages?
Flats (Trays)
Flats are the tray structures that hold the inserts
and pots. Inserts are plastic structures that hold
media and plants while they grow. Inserts may
be individual cell or divided to have 2, 3, 4 6, 8
cells per insert.
Determining how inserts are named.
1st number represents how many inserts fit into a
flat.
2nd number is a “0” that separates the first and
third number (acts as space).
3rd number represents how many cells are in the
insert.
If you multiply the first number by the third
number it will tell you how many cells are in the
insert.
Seed Sowing Lab
Objective: At the completion of this lab students will demonstrate how to properly sow seeds.
Materials:
1020 Flat (Tray)
Humindomes
Inserts
Soil
Pot Sticks (Labels)
Steps
Markers
Hose
Mist Wand (Waterer)
Seeds
1. Gather required materials.
2. Place the inserts in the flat and fill with media. (Check off with instructor)
3. Plant seeds as directed 3 times deeper then the thickness of the seed. (Check off with instructor)
4. Mist gently until water saturates soil and drains out of the bottom. (Check off with instructor)
5. Fill out two (2) pot sticks with the required information and place on each end of the flat. (See below for
example and check off with instructor)
6. Place humidomes on and place on a bench as indicated by you instructor.
