Not sure what your laws are like but here we are very limited on how much usable meds we are able to have. So we went for a system that let us harvest every couple of weeks with fewer plants with 4 plants flowering.
You can see 4 stages of ph level's. There is no question which was experiencing the highest levels and which had perfect levels.
We also use the CX line of nutes. It's the cleanest system we could find and get magnificent results.
