“Green is the prime color of<br />
the world, and that from<br />
which its loveliness arises.<br />

The Basic<br />
Knowledge
What<br />
Plants<br />
Need to<br />
Grow<br />
⊙ Sunlight<br />
⊙ Water<br />
⊙ Nutrients<br />
⊙ Air<br />
⊙ Soil is not a requirement – As<br />
long as the four is met, plants<br />
will grow.
KRATKY METHOD<br />
⊙ Named after B.A. Kratky.<br />
⊙ A passive hydroponics method.<br />
⊙ No crazy pumps and lights.<br />
⊙ Just a water reservoir and<br />
grow a plant on top of it.<br />
⊙ This passive system will<br />
provide plants with what they<br />
need.
Partial<br />
Kratky<br />
⊙ Recommended to still use soil<br />
coupled with expanded clay balls<br />
(LECA).<br />
⊙ Soluble fertilizers can be expensive.<br />
⊙ Trying to get the correct PH value<br />
can be difficult for beginners.<br />
⊙ Think of it as a low maintenance<br />
“self watering” system instead.

The Build
What You<br />
Need -<br />
Materials<br />
⊙ Recycled plastic bottle (non toxic<br />
ones preferred).<br />
⊙ Cheap cardboard. Waterproof.<br />
⊙ Veggie scraps that you can re-grow.<br />
⊙ Soil and LECA balls.<br />
⊙ Some strings.
What You<br />
Need -<br />
Tools<br />
⊙ A pair of scissors.<br />
⊙ Hot glue.<br />
⊙ Tape – Masking tape, duct tape,<br />
whatever that holds things together.<br />
⊙ Spray paint if possible.
⊙ Cut and join the bottles<br />
together with glue and<br />
tape.<br />
⊙ Spray paint the bottles.<br />
⊙ Make a “holding box” for<br />
the bottle.<br />
⊙ Make smaller “pots” to<br />
grow the plants in.<br />
⊙ Add water, and secure<br />
the setup down with some<br />
strings.

Maintenance
Semi-regular<br />
Maintenance<br />
⊙ Not a totally hands-free system.<br />
⊙ Still need to top up with water from<br />
time-to-time.<br />
⊙ Check if pests are growing inside.<br />
⊙ If root rot (brown slimy roots)<br />
happens, quickly remove the plant,<br />
and change the water.
