Transcript of The Blue Jackets
-20 Plastic Net Pots
-Five small, square planters
-Expanded Clay Pellets
-4 3 Gallon Plant Trays
-Guano Liquid Nutrient
(for soil and water)
-Hydro Bubbler System
-Water Set Up: -5 Net Pots per 3 gal plant tray
-4 seeds per Net Pot
-Each plant tray gets 5 net pots filled
with different mediums. Box A- Clay
Pellets, Box B- Rockwool, Box C-
Rock Gravel, Box D- Soil
-In Boxes A-C: filled with one gallon
of water, with added nutrients (according
to Guano Nutrient directions). Plants in soil
are watered with nutrients diluted in water,
-Hydro Bubblers placed in Boxes A-C. Materials: Plant Height in Cm Quantitative: Hypothesis:
We postulate that the Spinach plants will initially grow faster in Rockwool, but will develop fuller root systems, and overall more stable fitness in the Expanded Clay Pellets. We also postulate that the plants grown in soil will develop at a slower rate than the other three growth mediums (gravel, rockwool, expanded clay pellets). -Initially the plants potted in soil
grew at a much slower rate, while the plants in the Extended Clay Pellets exhibit a steady, and faster growth rate than Rockwool or Gravel. In the end, plants potted in soil experienced a growth spurt and exceeded gravel growth.
Qualitative: -As we examined the plants during growth,
the plants grown in gravel maintained a
small and weak appearance, while Rockwool
eventually took on the same appearance in the middle of week 2. The extended clay pellets maintained bright coloring, and a healthy appearance throughtout the experiment, as did plants grown in soil. Pro's and Con's Hydro. Advantages:
-Soil gardens can offer more complete amount of nutrients and minerals to your plants.
-They also contain naturally occurring good bacteria, that a farmer does not necessarily need to add in order for healthy growth.
Soil Advantages: -Allows for greater customization for your garden.
-You are able to grow more plants, more efficiently
in a smaller area.
-Especially beneficial for urban farming, and main-
taining renewable resources such as re-using water.
-Can be self sustainable if set up as an aquaponic
-Does not reuire extensive space
Hydro Disadvantages Soil Disadvantages -Require more initial work and cost
-Less complete types of nutrients.
-Less research as to what plants grow
more successful within specific mediums
so trial and error is still a part of the
growth process. -You have less control over pests and diseases.
-Not as much space for oxygen exchange.
-Soil requires more water, and water that is non

to surrounding ecosystems from run-off and pesti-
