Doc's kit really isn't as complex as it looks. This is my second time using it, transplant day is rough heavy lifting and will probably be rough again at harvest time but other than that it's just water them once a week with whatever mix the chart says, and spray the next day.
Last year I grew OG Kush clones with MegaCrop, Rx Green, and Doc Buds and to be honest after the cure it was really hard to tell them apart. I did think Doc's was probably a bit smoother until the full cure, Rx Green yielded the best and was pretty close to Docs, and MegaCrop was easiest to grow and wasn't too far behind the other two in quality of buds but was a bit lower yielding.
