Lechuza self watering plant pot (Wolverley DY11)

“LECHUZA Self Watering Plant Pot DELTINI Small Plastic Indoor Plant Pot without Drainage Hole D14 H18 cm White High-Gloss“ - bought this from Amazon in 2016 but didn’t work for my African violet and has just been stored since. Hopefully someone can make a better go at this with other plants. Link to see more - https://www.amazon.co.uk/dp/B00FJYMIIY/ref=pe_385721_145395771_TE_dp_1
