a pre filter is just a filter that goes over your carbon filter to filter dust or anything that will clog your carbon prematurely.
Rubberbubbler Reviewed by Rubberbubbler on . Blue Mystic grow log... Whats up... So finally got my strawberry male done and gone with pollen in the freezer. My Blue Mystic beans cracked in less than 6 hours so I am pumped to see what they can do. Now this will be my 2nd attempt at hydro. First was my strawberry male that did great. Will be using two 5 gallon DWC buckets with Fox Farms nutes. Rockwool plugs in hydroton, 3" netpots, and a UFO style LED inside my homebox tent. Hopefully some people with a hydro green thumb can keep an eye on these Rating: 5
