13 lt Monotub


This 13 litre mini monotub is used to spawn grain spawn into bulk substrate. It comes with the correct sized holes drilled and fulled with poly-fil for fresh air exchange.

It is the perfect size to spawn one of our grain kits with your bulk recipe at a ration of 1 part grain spawn (800ml) to 3 parts bulk substrate (2.4l)

A common bulk substrate recipe is 2 parts coco choir : 1 part vermiculite : 1 part horse manure , this needs to be sterilized at between 65C – 75C for 90 minutes and let cool to room temperature before being mixed with your grain spawn.

Optional Extra: add a heating pad to increase the temperature of the substrate in your monotub by about 5 degrees. Plug not included.
