Yes our entire lineup works well with DWC, now how much should you use?
A good rule of thumb is to use the online calculator or feed chart (insert link) and use approximately 55% - 65% of the normal rate. 
For example say it was 5 ml per litre on the soil recommendation, for DWC you would use 0.55 x 5ml = 2.75 ml or at the higher end 0.65 x 5ml = 3.25 ml.
