Hydroponic systems make an already vigorous sativa grow at a pace that is hard to manage, with stretch in the first weeks of flower hitting 10 centimetres a day in a DWC bucket. The upside is a shorter veg and quicker finish, the downside is that any reservoir mistake shows up in hours rather than days. Grower reports comparing DWC and coco for the same Haze cross are gathered on https://hazesativaseeds.com. Not for a first sativa, but worth trying on a later run.
