Yea I been using FF line of products for at least 2 years now.
I used there ocean forest mixed with perlite
I used there soil lines all of them combined as directed when making "Moonshine Soil Mix" which is a super soil!
I also use there nutes for my plain DWC. I do not have a water pump just 4 10 inch air stones running off of two good size air pumps. In a 10 gallon tote of course, 3 system site. It is a DIY I made myself.
I am using just started today hygrozmye stuff and liquid karma. Guy at the hydro store told me to buy clear ex to flush out. I believe i missed that week according to ff schedule but can do it next change out.
When it comes to the DWC, It is my first time, however I have been using reduced feedings of all products I use.. I consider myself a newbie still. I also clean out the tub and flush it out with several gallons of tap water which is readily available from a hose with sprayer. The force from the sprayer helps remove residue build up.. plus I have a drainage...
Just some extra steps to avoid me screwing up... I have had some trial and error, hopefully adding the liquid karma and hygrozyme will not do any harm to my plants.
I love Fox Farms line of products, I am just not convinced about there soluables...but then again I am new...
