Soil health is the foundation of farming productivity. Fertile soil provides the essential nutrients to plants and allows water and air to infiltrate, roots to explore, and biota to thrive. Soil health and soil quality are terms used interchangeably to describe soils that are not only fertile but also possess adequate physical and biological properties to sustain productivity, maintain environmental quality and promote plant health.

 Step by Step instructions highlighting this simple method that requires zero drain to waste.

Step 1

Set your Grow Tray up on table in an ergonomic friendly height.

Purchase 3 x 4 grow tray –

Step 2

(2)  Square Soft Pot(s)
(1)  Plastic Tray
  • 3′ x 4′ Tray – (2) 34″ X 22″  Square Soft Pots (pictured below)
  • 4′ x 8′ Tray – (8) 22″ x 22″ Square Soft Pots

Step 3

Tuck in the edges so the dirt can fill in the gaps of the Square Soft Pots into the corners of the plastic trays.

Step 4

Select your soil mix.  SGS recommends using a light mix of soil rather than heavy NPK loaded soils for Sea of Green.
Additional Options:  Adding perlite to the bottom of the Square Soft Pots will add more drainage and an extra layer to keep the roots from resting directly in water.  Due to the light soil mix ability to drain out quickly  during the sea of green application this step is not needed if the tray has adequate drain channels.

NOTE: Recommended option is to add worm castings to base mix if your base mix soil does not already contain the worm castings.

Step 5

Load soil mix first.

Step 6

Add worm castings.

Step 7

Evenly mix up both the soil mix and worm casting together.

Step 8

Try and target 6.5 to 7 inches of soil height.  Using cuttings, your feeder roots will go wide not deep.

Step 9

For “sea of green” vertical application, the target for 80% of the strains is one plant every 4 inches.  This “four plants per cubic foot” is the baseline for all vertical grow decks.
SOG Plant Count Rule of Thumb
(4 plants every cubic ft.)
3′ x 4′ Tray
(2) 34″ X 22″ Square Soft Pots  (24 plants each)
48 total plants
4′ x 8′ Tray
(8) 22″ x 22″ Square Soft Pots  (16 plants each)

128 total plants

Step 10

For “sea of green” vertical application, its best to run a veg 18-6 schedule for 6-7 days after transplanting from clone stage.

Step 11

After a few days of running the light schedule in a veg 18-6 schedule the clones start to recover and strengthen.  Another important note is to adjust the light intensity at this veg transition stage around 180-200 micromoles.

Step 12

After 6-7 days of running in a veg 18-6 schedule the clones will jump up a few inches in one day.  This is when you flip your clones to flower schedule of 12 hours on and 12 hours off and increase the intensity to 300 micromoles at the canopy.  See our SGS grow charts for full Smart Grow Cycles.
