they do not look to good going to put in dirt like stuff once I get home again . decided to try making new buckets . I got some free pails from the local truffle shop , They recycle these all the time . 4" net cup and some Hydro rocks , Its only a 4 watt air pump . I actually purchased an 18 watt one , but its so nosey I refuse to use it lets hope this is enough . tested the old waters PH was way out . thinking bacteria growth or something not sure . hope these bigger pails and top reflectors will help . still seriously thinking of putting in Dirt as just growing so slow its crazy , I know I am just new to DWC or they would be growing faster plus its not a real set up lul .
