Run Off Catchment Gutters

Run Off Catchment Gutters are an economical way to collect nutrient runoff from media filled bags and slabs and divert it to a catchment tank.

When using a Drip fertigation system the grower usually maintians a run off volume of between 10 – 30% of the amount of nutrient solution applied to the crop.

This ensures the growing media (e.g. cocoslabs) are well flushed and excess nutrient salts do not accumulate in them.

The runoff that flows from the base of the cocoslabs therefore needs to be collected and diverted to a catchment tank where it can be used on outdoor soil crops, or else the runoff can be filtered, treated and reused in a dilute form in combination with fresh nutrient solution.

If the nutrient runoff is left to drain into the greenhouse floor it can promote the growth of algae on the floor and subsequent gnat fly infestation. Gnat flies are attracted to algae and bring soil borne diseases into the greenhouse on their legs and wings.

The excess runoff can also drain through the soil and create long term ground water contamination issues in nearby streams and rivers due to the excess nutrients leaching into the environment. This may be prohibited by local authorities or it soon will be.

A runoff catchment system therefor removes the excess runoff from the greenhouse and diverts it to a collection tank for reuse. 

Pure Hydroponics can supply a flexible or rigid catchment gutter system to suit different budgets or applications.
