my opinion, if u want one
dwc is the way, i have done soil, rockwool and hydro. all taste as good as eachother, but dwc is awesome for growth rate and yield, never mind ease of growing, no mess , medium from the tap ffs
... the secret i think is in the flush, which again is easier with dwc, one min they gt nutes available, quick bucket change and hey presto now its jus water
i still flush for 10 days or so in dwc, by this point the plant is yellow, and she always tastes great..
as for cost, u can set yaself up abucket for 15 quid, and that will last u years, u can re use the hydroton pebbles, the net pot ( unless split by dreadlock roots
) and water is in the tap,, grow one plant and yield as much as 2/3 soil grown plants hmmmmm easy choice for me, although others are bound to diagree, or at least we hope so
