Hydroponics:
Bigger Yields – More Nutrition From Your Outdoor Garden!
About
the Author: Chris Wimmer is an urban hydroponic hobbyist who uses hydroponics
to maximize his 400 square foot yard and extend the short Chicago growing
season. Chris blogs about his hydroponic experiences at CaptainHydroponics.com.

Incorporating the elements of a hydroponic
system into outdoor gardening is the best way to ensure you get the biggest
yields and healthiest most nutrient-dense fruits, veggies, and herbs come
harvest time!
With indoor hydroponics, proper lighting
can be a challenge from a budget perspective, but with the powerful and “free”
sun shining down on your crops, bigger yields are always possible using a
soil-less, automated growing system.
Hydroponics
Defined:
Hydroponics maximize nutrient and oxygen
uptake in plants by eliminating soil from the mix. Plants are rooted in an
inert, bacteria free media such as peat moss, tree bark fibers, rockwool,
spagnum, perlite, clay or stone.
There are hundreds of variations to the
media used, but all provide a non-restrictive base for the plant's root system;
where a feeding solution containing water, oxygen, and fertilizer can be
introduced to the plants every few minutes via an automated watering system.
Slow and steady wins the race...
The plant's root system is “spoon-fed” what
it needs, then the excess drains out of the bottom of the planter, and back to
a nearby reservoir where it's held until a pump's activated via a timer a few
minutes later, and the plants receive another feeding.
Soil-free keeps the root system clean and
healthy, eliminates the plants wasting time searching for nutrients in the
soil. This maximizes the plant's ability
to produce healthy greens, veggies, fruits, or flowers.
Soil suffocates...
Soil, by comparison can retain too much water,
allowing bacteria to form (which bugs and parasites just love) and smothering
the root system of the plant blocking oxygen uptake.
Calcium and salt levels build in the soil,
slowly restricting its ability to uptake nutrients during the vegetation and
blooming phases. The plant's root system is also forced to grow downward in
search of more nutrient and oxygen-rich soil.
This means the plant has to use the energy
it receives from the sun (photosynthesis) to grow a larger root system, rather
than fortifying its stalk and producing seed-bearing fruits, veggies, flowers,
etc.
Benefits of
Hydroponics:
- Plants get all the nutrients they need – no wasted water or
fertilizer (25% of that used in soil grows)
- Little if any pesticides are needed – many crop eating bugs
live in soil
- Bigger yields – up to 10 times larger than soil
- Less babysitting your garden – an automated system can thrive
virtually on its own
- No weeding – weeds need soil to grow
Crop
Suggestions:
You can grow anything hydroponically but it's
important to do your research beforehand. There are many guides, videos, and
blogs out there which it can be difficult to decide where to start.
If you're just getting started, stick to
compact plants that don't require too much space, until you learn the ropes of
setting up your feeding system, maintaining a proper PH, and all the other
particulars. Corn, squash, zucchini, and melons are all best avoided as they
are large or create large vine systems.
Instead try these plants...
·
Herbs of all kinds – rosemary,
tyme, tarragon, sage, parsley, mint, dill, oregano (go nuts!)
·
Veggies – lettuce, cabbage,
watercress, radishes, peppers,
·
Fruits – tomatoes, raspberries,
blackberries, grapes, strawberries
Based on your crops of choice you can then
pick the best system. For herbs and
lettuce like veggies, I’d suggest starting with a simple lettuce raft. For larger fruits and vegetables, I’d
suggest starting with a basic bucket system which you can find on instructables.com.
