Our indoor gardens are often challenged by limited space and sun but it is still pleasant to live surrounded by plants we love.
Since 2015 to accommodate our expanding strawberry garden, we grew vertically on our windows as well as horizontally on tables by the windows. We made pots out of recycled PET ( polyethylene terephthalate ) bottles to hang.
There are several reasons why we love these plastic bottles –
- Weight – Lightest among any other pots
- Free of charge and yet harmful to our environment if we just throw. Go Recycle!
- Cut-able – can be customized for individual plants’ needs
- Versatile – suitable for soil based or Kratky Hydroponic
SOIL BASED Bottles
Soil based needs a narrow dripping point, as we do not want water to splash on our floors whenever we irrigate our hanging gardens. Thus we used cap side for drip off and wider end at the bottom for plants.
This is how we turned ordinary plastic bottles into hydro or soil based hanging gardens.
Step 1 – Cut holes to string ropes through for hanging
Kratky Hydroponic – Cut 2 holes at opposite side of the bottle near the cap. We chose the wider end for inserting hydroponic bottles.
Soil based – Cut holes at bottom end of hanging pot for strings.
Step 2 – Knots at each hole to prevent wear and tear by rubbing, also keep bottle steady in the wind. Top knot (not shown) for hook to latch.
Step 3 – Cut hole (s) to insert hydroponic pot or plants (soil based)
For Kratky bottles (non circulating hydroponic) – Measure against hanging pot to estimate the size of opening to cut. I preferred to cut smaller and then widen when the plant is inside hanging bottle.
Soiled based – Cut size of hole as desired to plant
Step 4 –
Hydroponic – Cut holes at the bottom of hanging pot to drain rainwater if outdoor (prevent mosquitoes breeding)
Soil based – Net or cap over with holes for drainage
Wear Socks! – To shield liquid base or roots end from light (heat) to prevent unsightly algae.
Hydro pots are lighter than soil based pots
In late September 2018, these PET bottles pots became “fashion” accessories after the S-hooks ZehZeh’s craze in Singapore! Just for laughs –
The best thing about this no-tech vertical garden, beside being cheap to maintain and built, is that it allow both soil based and hydroponic to grow together.
Happy Green gardening by re-using PET bottles! 🙂
