Been using sunshine for over a year now... no ph problems here. Four grows in a row came out every time. Just have to careful with measuring the nutes; I use AN with molasses during flower. Seems to drain really well - I have not had any overwatering issues. Sunshine seems to me to be the most painless method, maybe that is just what I am used to. Still chuckling over someone I know who was bragging about how 'hydro is the only way to go"- he went and spent a couple thousand $$ and six months later still has not one bud to show for it
