Dwc is super easy bro I also run a couple of dwc buckets growth rates are awesome.
I haven't had a failed run yet on DWC, I ended up with a large male last time and had to toss him which was disappointing. I do think there's lots of room for a new grower to make mistakes though (ie overcorrecting nute issues etc). I have to agree with you on growth rate though, lots of daily growth.
