Its a good question but I don't really have experience with DWC so I cant speak about this with any authority. I would say that you can make any method simple or difficult depending on any number of variables.
What really makes what i do easy are two things.....
1)Promix straight out of the bag...no amendments.
2) Jacks Classic nutes
If i wanted to make this difficult I could just change my nutrient brand to one of the many overpriced selections available. I was at the hydro store the other day and the salesmen tried to sell me a new clone solution that cost $70 for a 8 oz bottle (approx). He gave me the companies brochure showing all the products you "need" to make the best buds. There must be 10 different things you need to add on top of whatever your favorite base nutrient might be.
I guess this stuff might work but you would need a fat wallet to keep paying for it, and a science degree to use it properly.
