These 18 litre black square pots are made from high quality plastic - they are thick, strong and will last grow after grow. Square pots are well liked within the hydroponic and horticulture industry as they take up less space when compared to regular round pots.
This 18L pot with holes can be used as a regular pot - the other purpose is to use it in conjunction with our square 24 litre pot with no holes (sold separately). This 18L pot will easily slide into the 24 litre pot and since the 24L bucket is deeper it acts a small reservoir. From there you can run an outlet from the bottom 24L pot and run a drip line into the top 18L pot.
