Cheers man- i use sm90 in my res and have never had any root rot issues- grown over 40 plants using this system now. It helps keep the res clean too.
I use the nutrient pump to empty the res. Only empty qnd clean it 2 maybe 3 times during a grow.
Never used qutopots myself but theyre a great system for sure man.
@A-Train so far so good
i made 4 nice grows with it, no problem...then i had the problem...i didnt know about this product.thanks a lot for the info and maybe you will save me some money...as im making my plans for this year.no doubt about autopots but all am thinking is that it will give pretty much the same yields with wilma.
