The Grow MachineView Instructable »
Hey, well with this one I didn't get any contamination which was surprising as since then i have been working with sterilisation processes to stop potential unwanted bacteria and molds. In all honesty I am quite surprised this worked so well. Now I sterilise in an autoclave for 3 hours, i used filter bags with a vacuum seal and grow in a Laminar flow, some work fantastically but some do still get contaminated. I think it depends on what substrate as I was using spent beer grain which was much more vulnerable to contamination than straw was.
Hey, Its from wholefoods, it is the Clearspring brand but I am sure it can be found online or in other food shops.
