4. 1 The Basic Knowledge
5. What Plants Need to Grow ⊙ Sunlight ⊙Water ⊙ Nutrients ⊙Air ⊙ Soil is not a requirement – As long as the four is met, plants will grow.
6. KRATKY METHOD ⊙Named after B.A. Kratky. ⊙A passive hydroponics method. ⊙ No crazy pumps and lights. ⊙ Just a water reservoir and grow a plant on top of it. ⊙ This passive system will provide plants with what they need.
7. Partial Kratky ⊙ Recommended to still use soil coupled with expanded clay balls (LECA). ⊙ Soluble fertilizers can be expensive. ⊙Trying to get the correct PH value can be difficult for beginners. ⊙ Think of it as a low maintenance “self watering” system instead.
8. 2 The Build
9. What You Need - Materials ⊙ Recycled plastic bottle (non toxic ones preferred). ⊙ Cheap cardboard. Waterproof. ⊙ Veggie scraps that you can re-grow. ⊙Soil and LECA balls. ⊙ Some strings.
10. What You Need - Tools ⊙ A pair of scissors. ⊙Hot glue. ⊙ Tape – Masking tape, duct tape, whatever that holds things together. ⊙Spray paint if possible.
11. ⊙ Cut and join the bottles together with glue and tape. ⊙ Spray paint the bottles. ⊙ Make a “holding box” for the bottle. ⊙ Make smaller “pots” to grow the plants in. ⊙ Add water, and secure the setup down with some strings.
12. 3 Maintenance
13. Semi-regular Maintenance ⊙ Not a totally hands-free system. ⊙Still need to top up with water from time-to-time. ⊙ Check if pests are growing inside. ⊙If root rot (brown slimy roots) happens, quickly remove the plant, and change the water.
