How I Fit a Hydroponics Laboratory Into My Tiny Office

So both of the reservoirs I’m using currently hold 20 litres of water, and the hydrogen peroxide I’m using is at an 11.9% concentration. The recommendation from the manufacturer on this hydrogen peroxide is 1ml per litre of water for daily use or 2ml per litre two to three times per week.

So, I was adding 20ml daily and am now also testing 10ml to see if there is a notable difference.
