i put the in a huge metal tub 150 gallons and add a bit of 3% proxide 1 gallon and start my fire underneath and let boil.all the roots left i missed fall apart and every thing is clean then i have a spegetti sive i use to scoop them out when cooleda bit.and rinse with garden hose , this method...
on my setup i have 4x8 table 24 adjustable flow drippers that run on 3 mins. 20 mins off and i also have 6 sprayers underneath the cover that mist the roots at the same time,but I use hydroton, and have a big pump, any one try this
